Socioeconomic Indicators of Treatment Prognosis for Adults With Depression: A Systematic Review and Individual Patient Data Meta-analysis

Financial performance of people with acquired cognitive impairments or affective disturbances - A prospective, European-wide study

BACKGROUND

Financial capability, encompassing both financial competence and financial performance, is essential for independent living. However, individuals with neurological and psychiatric disorders often demonstrate difficulties with financial capability. This study examined the influence of common neurological and psychiatric conditions, i.e., Alzheimer's disease (AD), Parkinson's disease (PD), stroke, and affective disturbances, on financial performance.

METHODS

Prospective data from wave 8 (n= 53,695) and wave 9 (n= 69,477) of the Survey of Health, Retirement and Ageing in Europe were used, which included individuals aged 50+; part of Wave 8 and all of Wave 9 data were collected during the COVID-19 pandemic. Logistic regressions and group comparisons were conducted to analyze the influence of self-reported disease diagnosis on three aspects of (future) financial performance: difficulties in managing money, difficulties in making ends meet, and debt situation.

RESULTS

Compared to controls, participants with one of the four conditions reported significantly more often having difficulties managing money. Within the AD group, over half of the participants reported these difficulties. The different diagnoses also predicted both current and future difficulties in managing money and making ends meet. However, only affective disorders were associated with and predicted a higher likelihood of having household debts.

DISCUSSION AND IMPLICATIONS

Compared to controls, individuals with PD, AD, stroke, or affective disorders are more prone to experiencing impairments with both current and future financial performance, potentially facing financial difficulties. These results emphasize the importance of recognizing financial difficulties in such individuals and offering financial assistance when needed.

Association Between Socioeconomic Status and Neuropsychiatric Symptoms in the UK Biobank: The Moderating Role of Sociability

Introduction: Neuropsychiatric symptoms are signs of cognitive decline and associated disorders. The effects of socioeconomic status and social interaction on cognitive decline have already been well documented. Accordingly, the present study aimed to build on the work investigating those factors and cognitive health by examining the relationships between socioeconomic status, sociability, and neuropsychiatric symptoms. Methods: Data from the UK Biobank (N = 301,848) were subjected to logistic regressions to examine the relationship between socioeconomic status, sociability, and neuropsychiatric symptoms and sociability to identify any potential moderator in the socioeconomic status-neuropsychiatric symptoms relationship. Specifically, socioeconomic status was defined by the Townsend deprivation index, while sociability was constructed using a cumulative score of four aspects. Meanwhile, neuropsychiatric symptoms were represented by depression, anxiety, and irritability, each of which had a genetic risk score calculated. Results: Individuals who reported lower socioeconomic status also reported more depression and anxiety, while those with higher sociability reported fewer depression and anxiety. Further, it was found that sociability moderated the relationship between socioeconomic status and two symptoms: depression and anxiety. No significant moderating effects were found regarding irritability. Conclusion: The study results indicate the need for interventions aimed at neuropsychiatric symptoms to reduce possible cognitive disorders. They also demonstrate the need to eliminate economic and social disparities and the importance of improving sociability.

Clinical and cost-effectiveness of lithium versus quetiapine augmentation for treatment-resistant depression in adults: LQD a pragmatic randomised controlled trial

Background

Lithium and several atypical antipsychotics are the recommended first-line augmentation options for treatment-resistant depression; however, few studies have compared them directly, and none for longer than 8 weeks. Consequently, there is little evidence-based guidance for clinicians when choosing an augmentation option for patients with treatment-resistant depression.

Objectives

This trial examined whether it is more clinically and cost-effective to prescribe lithium or quetiapine augmentation therapy for patients with treatment-resistant depression over 12 months.

Design

This was a parallel group, multicentre, pragmatic, open-label superiority trial comparing the clinical and cost-effectiveness of lithium versus quetiapine augmentation of antidepressant medication in treatment-resistant depression. Participants were randomised 1 : 1 at baseline to the decision to prescribe either lithium or quetiapine.

Setting

Six National Health Service trusts in England.

Participants

Eligible participants were aged ≥ 18 years, met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for major depressive disorder, scored ≥ 14 on the 17-item Hamilton Depression Rating Scale and whose depression had had an inadequate response to at least two therapeutic antidepressant treatment trials in the current episode, with a current antidepressant treatment at or above the therapeutic dose for ≥ 6 weeks. Patients with a history of psychosis or bipolar disorder were excluded. Patients were judged suitable for either treatment.

Interventions

After randomisation, pre-prescribing safety checks were undertaken as per standard care and trial clinicians decided whether to proceed with prescribing the allocated medication. Trial clinicians received recommendations for titration and dosing in line with current clinical guidelines; however, dosing regimens could be altered according to tolerability and response. Participants were followed up using weekly self-report questionnaires and 8-, 26- and 52-week research visits.

Main outcome measures

The co-primary outcome measures were depressive symptom severity over 52 weeks, measured weekly using the self-rated Quick Inventory of Depressive Symptomatology, and time to all-cause treatment discontinuation of the trial medication. Economic analyses compared costs between the two treatment arms over 52 weeks, from a National Health Service and Personal Social Services perspective, and a societal perspective.

Results

Two hundred and twelve participants were randomised, 107 to quetiapine and 105 to lithium. The quetiapine arm showed a significantly greater reduction in depressive symptoms than the lithium arm over 52 weeks (quetiapine vs. lithium area under the differences curve = -68.36, 95% confidence interval: -129.95 to -6.76, p = 0.0296). Median days to discontinuation did not significantly differ between the two arms (quetiapine = 365.0, interquartile range = 57.0-365.0, lithium = 212.0, interquartile range = 21.0-365.0), p = 0.1196. Quetiapine was more cost effective than lithium. Thirty-two serious adverse events were recorded, only one of which was deemed possibly related to the intervention (lithium).

Limitations

The trial was unblinded, therefore expectancies regarding the trial medications may have influenced the results. Further, there was substantial missing data for some of the secondary outcome measures.

Conclusions

As well as being more cost-effective, quetiapine may be a more clinically effective augmentation option for treatment-resistant depression.

Future work

Examining predictors of treatment response, including clinical, sociodemographic and biological factors, will help establish whether there are additional factors to consider when choosing an augmentation treatment for treatment-resistant depression.

Psychological Therapy Outcomes and Engagement in People of Different Religions

Importance

Identifying whether people of minoritized religious identities are less likely to benefit from psychological therapy is key to tackling inequalities in mental health treatment.

Objective

To assess inequalities in the effectiveness of routinely delivered psychological therapy across religious groups and by the intersections with ethnicity.

Design, Setting, and Participants

Retrospective cohort study including all patients who completed a course of treatment at 5 London-based National Health Service Talking Therapies for anxiety and depression (NHS TTad) services between 2011 and 2020. Individuals reported their religion using routine patient records collected by the services. Data were analyzed from September 2023 to October 2024.

Exposures

Self-identified religion was categorized into (1) no religion, (2) Christian, (3) Muslim, and (4) other (which was further categorized into Buddhist, Hindu, Jewish, Sikh, and any other in a sensitivity analysis). Ethnicity was conceptualized as a potential confounder and separately as an effect modifier. Self-reported ethnicity was categorized based on UK Census codes into Asian, Black, mixed race, White, and other ethnic groups.

Main Outcomes and Measures

Psychological treatment outcomes used to assess NHS TTad services nationally, including reliable recovery, recovery, and reliable deterioration. Dropout from treatment was also examined. These outcomes were defined based on pre-post treatment changes in depression and anxiety symptom measures according to national guidelines.

Results

A total of 70 098 patients with data on self-reported religion were included in the study (mean [SD] age at referral, 39.2 [14.1] years; 47 797 [68.2%] female). After adjusting for sociodemographic, treatment-related, and clinical characteristics, the odds of reliable recovery were higher in patients who did not have any religious belief (odds ratio [OR], 1.34; 95% CI, 1.26-1.42) or self-reported Christian (OR, 1.39; 95% CI, 1.31-1.48) and other religion (OR, 1.25; 95% CI, 1.17-1.34) compared with Muslim patients. While treatment outcomes improved each year in all groups, Muslim patients remained least likely to improve and more likely to deteriorate. There were interactions between religion and ethnicity; in particular, Muslim patients of White or other ethnic backgrounds had worse outcomes than Muslim patients of Asian, Black, or mixed race ethnic backgrounds and compared with non-Muslim patients of those ethnicities.

Conclusions and Relevance

In England, patients who identified as Muslim, and particularly those of White or other ethnicities, had poorer outcomes from psychological therapies for depression and anxiety disorders than patients who reported no religion or any other religion. This may be partly due to unmeasured characteristics that warrant further investigation (eg, nationality and asylum-seeking or refugee status). Best practice guidelines on working with people of minoritized ethnicities may inform some of the changes needed to reduce inequalities, but must address religious identity separate from ethnicity, as well as their intersections.

Self-report measures of fear learning and extinction and their association with internet-based cognitive behavioural therapy outcome

Despite the widespread use of cognitive-behavioural therapy (CBT), only about half of patients respond favourably. Understanding whether relevant psychological processes are associated with treatment response could help identify patients at risk of non-response prior to treatment and improve their outcomes by enabling clinicians to tailor interventions accordingly. Fear conditioning tasks are a valuable tool for studying the learning processes associated with anxiety disorders and their treatment. This study examined associations between outcomes from a remote fear conditioning task and responses to internet-based CBT. Anxious adults (n = 112) completed a fear conditioning task before receiving internet-based CBT. Participants rated their expectancy of an aversive noise (unconditioned stimulus; US) in response to a reinforced conditional stimulus (CS+) and a nonreinforced conditional stimulus (CS-) during acquisition, followed by extinction where neither stimulus was reinforced. Anxiety symptoms were assessed before each CBT session. Linear regression models indicated no significant association between mean US-expectancy ratings for 'safe' stimuli (acquisition CS- and extinction CS+) and change in anxiety across treatment. These findings contribute to the mixed literature on fear conditioning's role in treatment outcomes, highlighting the need for further research to elucidate the complex interplay between fear conditioning processes and response to CBT in anxiety disorders.

Clinical and cost-effectiveness of lithium versus quetiapine augmentation for treatment-resistant depression: a pragmatic, open-label, parallel-group, randomised controlled superiority trial in the UK

BACKGROUND

Lithium and quetiapine are first-line augmentation options for treatment-resistant depression; however, few studies have compared them directly, and none for longer than 8 weeks. We aimed to assess whether quetiapine augmentation therapy is more clinically effective and cost-effective than lithium for patients with treatment-resistant depression over 12 months.

METHODS

We did this pragmatic, open-label, parallel-group, randomised controlled superiority trial at six National Health Service trusts in England. Eligible participants were adults (aged ≥18 years) with a current episode of major depressive disorder meeting DSM-5 criteria, with a score of 14 or higher on the 17-item Hamilton Depression Rating Scale at screening who had responded inadequately to two or more therapeutic antidepressant trials. Exclusion criteria included having a diagnosis of bipolar disorder or current psychosis. Participants were randomly assigned (1:1) to the decision to prescribe lithium or quetiapine, stratified by site, depression severity, and treatment resistance, using block randomisation with randomly varying block sizes. After randomisation, pre-prescribing safety checks were undertaken as per standard care before proceeding to trial medication initiation. The coprimary outcomes were depressive symptom severity over 12 months, measured weekly using the Quick Inventory of Depressive Symptomatology, and time to all-cause treatment discontinuation. Economic analyses compared the cost-effectiveness of the two treatments from both an NHS and personal social services perspective, and a societal perspective. Primary analyses were done in the intention-to-treat population, which included all randomly assigned participants. People with lived experience were involved in the trial. The trial is completed and registered with the International Standard Randomised Controlled Trial registry, ISRCTN16387615.

FINDINGS

Between Dec 5, 2016, and July 26, 2021, 212 participants (97 [46%] male gender and 115 [54%] female gender) were randomly assigned to the decision to prescribe quetiapine (n=107) or lithium (n=105). The mean age of participants was 42·4 years (SD 14·0 years) and 188 (89%) of 212 participants were White, seven (3%) were of mixed ethnicity, nine (4%) participants were Asian, four (2%) were Black, three (1%) were of Other ethnicity, and ethnicity was not recorded for one (1%) participant. Participants in the quetiapine group had a significantly lower overall burden of depressive symptom severity than participants in the lithium group (area under the between-group differences curve -68·36 [95% CI -129·95 to -6·76; p=0·0296). Time to discontinuation did not significantly differ between the two groups. Quetiapine was more cost-effective than lithium. 32 serious adverse events were recorded in 18 participants, one of which was deemed possibly related to the trial medication in a female participant in the lithium group. The most common serious adverse event was overdose, occurring in three (3%) of 107 participants in the quetiapine group (seven events) and three (3%) of 105 participants in the lithium group (five events).

INTERPRETATION

Results of the trial suggest that quetiapine is more clinically effective than lithium as a first-line augmentation option for reducing symptoms of depression in the long-term management of treatment-resistant depression, and is probably more cost-effective than lithium.

Effective Components of Collaborative Care for Depression in Primary Care: An Individual Participant Data Meta-Analysis

Importance

Collaborative care is a multicomponent intervention for patients with chronic disease in primary care. Previous meta-analyses have proven the effectiveness of collaborative care for depression; however, individual participant data (IPD) are needed to identify which components of the intervention are the principal drivers of this effect.

Objective

To assess which components of collaborative care are the biggest drivers of its effectiveness in reducing symptoms of depression in primary care.

Data Sources

Data were obtained from MEDLINE, Embase, Cochrane Library, PubMed, and PsycInfo as well as references of relevant systematic reviews. Searches were conducted in December 2023, and eligible data were collected until March 14, 2024.

Study Selection

Two reviewers assessed for eligibility. Randomized clinical trials comparing the effect of collaborative care and usual care among adult patients with depression in primary care were included.

Data Extraction and Synthesis

The study was conducted according to the IPD guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. IPD were collected for demographic characteristics and depression outcomes measured at baseline and follow-ups from the authors of all eligible trials. Using IPD, linear mixed models with random nested effects were calculated.

Main Outcomes and Measures

Continuous measure of depression severity was assessed via validated self-report instruments at 4 to 6 months and was standardized using the instrument's cutoff value for mild depression.

Results

A total of 35 datasets with 38 comparisons were analyzed (N = 20 046 participants [57.3% of all eligible, with minimal differences in baseline characteristics compared with nonretrieved data]; 13 709 [68.4%] female; mean [SD] age, 50.8 [16.5] years). A significant interaction effect with the largest effect size was found between the depression outcome and the collaborative care component therapeutic treatment strategy (-0.07; P < .001). This indicates that this component, including its key elements manual-based psychotherapy and family involvement, was the most effective component of the intervention. Significant interactions were found for all other components, but with smaller effect sizes.

Conclusions and Relevance

Components of collaborative care most associated with improved effectiveness in reducing depressive symptoms were identified. To optimize treatment effectiveness and resource allocation, a therapeutic treatment strategy, such as manual-based psychotherapy or family integration, may be prioritized when implementing a collaborative care intervention.

Agomelatine as adjunctive therapy with SSRIs or SNRIs for major depressive disorder: a multicentre, double-blind, randomized, placebo-controlled trial

BACKGROUND

In general, traditional antidepressants often have limited efficacy in patients with major depressive disorder (MDD). Agomelatine, as an antidepressant with a different mechanism of action, might have adjunctive effects on traditional antidepressants. This study aimed to investigate the augmentation effect of agomelatine versus placebo in treating MDD patients who failed to respond to selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs).

METHODS

This is an 8-week, multi-centred, double-blinded, randomized, and placebo-controlled trial. Participants diagnosed with MDD and demonstrated inadequate response to SSRI or SNRI lasting at least 2 weeks were randomly allocated to receive either agomelatine or placebo in conjunction with SSRIs or SNRIs. The 17 items of the Hamilton Depression Scale (HAMD-17) were employed to assess depression severity. The primary outcome is the total score of HAMD-17 at week 8. Secondary outcomes included HAMD-17 scores at weeks 2 and 4 and clinical remission and response over 8 weeks. Adverse events (AEs) reported in both groups were recorded. A linear mixed model was established for both primary and secondary outcomes.

RESULTS

A total of 123 eligible participants were included, among which 60 were randomized into the agomelatine group, and 63 were randomized into the placebo group. The between-group difference in HAMD-17 score reduction from baseline to week 8 was not significant (difference = - 0.12, 95% CI = - 3.94 to 3.70, P = 0.90; Cohen's d = 0.022). In addition, we did not observe significant differences between the two treatment groups for secondary outcomes, including response remission, and AEs.

CONCLUSIONS

This study did not obtain significant findings in favour of the augmentation effect of agomelation for MDD patients. However, agomelatine was generally well tolerated and demonstrated a favourable safety profile when used in combination with SSRIs and SNRIs.

[Translated article] The influence of socioeconomic status and psychological factors on surgical outcomes of the carpometacarpal osteoarthritis of the thumb

OBJECTIVE

This study aimed to investigate to what extent people with carpometacarpal thumb osteoarthritis that are socioeconomically disadvantaged and have psychological disorders report higher pain levels and worse patient-rated upper-extremity functionality after surgical treatment.

MATERIAL AND METHOD

A single centre, retrospective observational cohort study analysing 100 patients diagnosed with thumb carpometacarpal osteoarthritis between 2013 and 2019. Patients were divided into two groups (50/50), depending on whether they received surgical or conservative treatment. The socio-economic status (ESeC classification) and presence of psychological comorbidities were investigated. Functional outcomes were assessed using the Visual Analogue Scale (VAS), Q-DASH questionnaire and Kapandji score. Current mental disorders were evaluated using STAI, PHQ-9 and PCS screening scales.

RESULTS

Measures of functional hand scores (Q-DASH) were higher and had considerably less pain in surgically treated participants, although thumb mobility (Kapandji) was more restricted. They were also associated with higher scores on psychological assessment scales. Sixty-four per cent of the patients came from lower socio-economic classes and suffered from poorer scores on the mental health screening questionnaires. Of the patients manage surgically, 54% were diagnosed of dysthymic disorder and showed significantly worse patient-rated upper-extremity function (Q-DASH questionnaire, median [IR]: 31.8 [20.5-54.6] than patients without psychological disorders (median [IR]: 13.6 [2.3-36.5]). No differences were found for patients with and without dysthymic disorder managed nonoperatively.

CONCLUSIONS

Patients with higher rates of depression, anxiety and pain catastrophizing behaviour showed significantly worse outcomes after surgery for osteoarthritis of the first carpometacarpal joint. Lower socio-economic class significantly influences levels of depression and anxiety but did not affect functional outcome. Surgical treatment of carpometacarpal thumb osteoarthritis achieved better self-perceived hand function (QDASH, VAS, Kapandji) than conservative treatment.

A systematic review of participant diversity in psychedelic-assisted psychotherapy trials

A lack of diverse and representative participant samples in mental health intervention research perpetuates mental health disparities. This issue has become a salient concern in studies of psychedelic-assisted psychotherapy (PAT), which is emerging as a promising mental health intervention. This systematic review evaluates the reporting, representation, and analysis of participant sociodemographic characteristics in randomized controlled trials (RCTs) of PAT. A total of 21 RCTs of psilocybin- and 3,4-methylenedioxy methamphetamine (MDMA)-assisted therapies (N = 1034) are summarized. Participants' gender (100%) and race or ethnicity (76%) were frequently reported, with socioeconomic status (SES) sometimes (57%) reported using heterogeneous metrics. Sexual orientation (9.5%) and immigration status (4.8%) were rarely reported, and no studies reported gender identity. Compared to their representation in the US population and non-psychedelic clinical trials, Black/African-American participants (2.2%) and Hispanic/Latino participants (7.2%) were significantly underrepresented in PAT RCTs. MDMA trials enrolled more diverse participant samples than psilocybin trials. Analyses on treatment effects based on demographic variables were virtually nonexistent. These findings underscore the need for more inclusive recruitment strategies, along with more rigorous reporting, to improve the generalizability of PAT research.

Social Determinants of Health Screening Tools for Adults in Primary Care: Protocol for a Scoping Review

BACKGROUND

Social determinants of health (SDH) have been shown to be predictors of health outcomes. Integrating SDH screening tools into primary care may help identify individuals or groups with a greater burden of social vulnerability and promote health equity.

OBJECTIVE

This study aimed (1) to identify the existing screening tools to assess social deprivation in adults in primary care settings; (2) to describe the characteristics of these tools and, where appropriate, their psychometric properties; (3) to describe their validity and reliability in those scales in which validation processes have been conducted; and (4) to identify evidence gaps and provide recommendations for future research.

METHODS

This study protocol was structured according to the Joanna Briggs Institute methodology for scoping reviews and reported according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. Furthermore, since not all SDH assessment tools are published as scientific papers, we will use a slightly modified form of the scoping review framework to retrieve specific information about specific tools for screening SDH in primary care contexts. The following electronic databases will be searched by 2 reviewers: MEDLINE (via PubMed), CINAHL Plus, Web of Science, and Scopus. In addition, the following sources will also be searched for gray literature: DART-Europe E-thesis Portal, OpenGrey, and Google Scholar. After the revision of inclusion and exclusion criteria, the titles, abstracts, and full text of the included studies will be separately screened by 2 reviewers. A PRISMA-ScR flowchart will be used to depict the sources of evidence screened, and data charting will be used to gain in-depth knowledge. The findings of the scoping review will be presented in both narrative and tabular formats, summarizing the existing literature on tools used for SDH in primary care settings. A critical analysis will be undertaken to address the variability in tool validation, cultural adaptability, and integration into different health care systems. Finally, key gaps in the existing evidence will be explored, and research priorities will be proposed, emphasizing the need for screening tools that are culturally sensitive, scalable, and easily integrated into primary care workflows. This critically appraised information may be useful for implementing SDH screening tools in primary care settings and may contribute to future research addressing feasibility and validation studies in different primary health care systems.

RESULTS

The study began in July 2024. Data collection is expected to be completed in April 2025, with publication expected in October 2025.

CONCLUSIONS

This scoping review will provide a comprehensive and critical description of the available tools aimed at screening SDH in primary care settings. Incorporating these tools into routine care has been recognized as a key strategy for addressing health inequalities, given the growing evidence base on the influence of SDH on health outcomes.

Socioeconomic factors and sex effects of postpartum maternal depression on offspring internalizing symptoms: a systematic review and meta-analysis

BACKGROUND

Postpartum maternal depression and socioeconomic factors are established risk factors for the mental health of offspring. It has been consistently unclear as to whether female or male offspring are more vulnerable to the effects of postpartum maternal depression at different stages of the child's life course. To determine whether the characteristics of postpartum maternal depression with a history of prenatal depression influence sex differences in offspring internalizing symptoms across childhood and adolescence, socioeconomic factors should be considered.

METHODS

We systematically searched PubMed, Embase, PsycINFO, CNKI, and SinoMed databases from inception to November 28, 2023, and selected longitudinal cohort studies that quantified sex differences in internalizing symptoms of children and adolescents. Pooled standardized mean differences (SMDs) were calculated using random-effects models. ROBINS-E tool was used to rate the quality of evidence.

RESULTS

Twenty-eight studies were eligible between 1997 and 2023, including 24,022 mother-child dyads. Sex-difference trajectories of offspring internalizing symptoms were identified after exposure to postpartum maternal depression, ranging from a lack of significant sex differences in childhood to a higher prevalence observed among girls than boys in adolescence (SMD, 0.25, 95% CI, 0.13-0.38). Economic income and maternal education affected the associations between the magnitude and concurrent recurrence of postpartum depression and significant sex differences in adolescent internalizing symptoms, respectively. After adjusting for socioeconomic factors, early nonconcurrent recurrence of postpartum depression was associated with greater odds of internalizing symptoms among adolescent girls than among boys (β = 0.03, 95% CI, 0.01-0.06); however, there was no statistical significance after adjusting for prenatal depression.

CONCLUSIONS

Socioeconomic factors differentially impacted the association between postpartum maternal depression and significant sex differences in adolescent internalizing symptoms. Independent of socioeconomic factors and prenatal depression, postpartum maternal depression was not associated with significant sex differences in adolescent internalizing symptoms. Therefore, the significant sex effects of postpartum maternal depression are more likely due to complex interactions between maternal depression and the intrauterine and postpartum environments that shape offspring sex-difference trajectories, with consequences occurring for later internalizing symptoms in adolescence.

Gender-specific dual effects of physical activity on depression and mortality: a nine-year cohort study in Chinese adults aged 45 and above

Background

Regular participation in physical activity (PA) reduces all-cause mortality (ACM) in the general population. However, the effects of PA on depressed patients and potential gender-specific responses have not been fully elucidated. In this study, we aimed to investigate the role of PA on new-onset depression and ACM in Chinese adults aged 45 year and older, with particular emphasis on gender differences.

Methods

This was a longitudinal cohort study that took place over a nine-year period and featured 2,264 participants drawn from the China Health and Retirement Longitudinal Study (CHARLS). PA levels were categorized into quartiles using metabolic equivalents (MET; minutes/week), and depression was evaluated according to the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10) scale. Specific relationships between PA, depression, and mortality were then investigated by applying multivariate logistic regression and Cox proportional hazards models.

Results

Highest quantile levels of PA were correlated with a 37% increase in the risk of new-onset depression in middle-aged (45-59 years) and older adults (>60 years). This association was predominantly influenced by a significant increase in the risk of mild depression (a score of 10-14 on the CESD-10) (odds ratio [OR]: 1.76; 95% confidence interval [CI]: 1.29-2.42, p < 0.001), with a more pronounced effect observed in women (OR: 1.83; 95% CI: 1.26-2.66, p = 0.002). A critical threshold for PA was identified at 4536 MET-minutes/week, beyond which the risk of depression increased significantly (p < 0.05). Conversely, higher levels of PA were linked to a 90% reduction in ACM (HR: 0.10; 95% CI: 0.02-0.44, p = 0.002), with the effect being more pronounced in men.

Conclusion

While PA reduces mortality, excessive activity may increase the risk of mild depression, particularly in women. These findings highlight the need for gender-specific PA guidelines that balance physical and mental health outcomes.

The mediating role of depression in the association between perceived financial wellbeing and somatization: a study in the context of Lebanon's financial crisis

The objectives of this study were to examine the association between financial wellbeing and somatization, in addition to the mediating effect of anxiety, depression and stress. To test such hypotheses, a cross-sectional study was carried out between September and October 2021; 403 participants (264 females; age = 32.76 ± 13.24 years) were recruited. Depression mediated the association between financial wellbeing and somatization. A worse financial wellbeing was significantly associated with more depression, which was associated with more somatization. Moreover, a worse financial wellbeing was significantly and directly associated with more somatization. Our study adds to the narrow body of research revolving around the relationship between financial wellbeing and somatization in Lebanese adults. Understanding that the effects of, depression are aggravated in a country such as Lebanon would help establish more preventative guidelines and mental health awareness campaigns. Identifying the correlates of somatization can also be translated into improved interventions.

The impact of sociocultural and psychological stress on the outcome of assisted reproductive technology in remarried families

OBJECTIVE

In China, there is a unique type of second marriage (SM) family where the woman is remarried, and the man is experiencing his first marriage. Additionally, the woman is older than the man. Therefore, these families experience many challenges: psychological, emotional, and societal pressure. Such family is a typical sample for studying sociocultural and psychological stress influencing on outcome of assisted reproductive technology (ART). This study aimed to investigate the impact of social psychological stress on the live birth outcomes AR.

METHODS

In this retrospective cohort, second marriage (SM) families who visited the Second Hospital of Hebei Medical University reproductive center between January 2012 to December 2022 were screened, and 561s marriage families (the SM group) with 5600 first marriage (FM) families (the FM group) were included undergoing their first ART cycles. The primary outcome of this study was the live birth rate (LBR).

RESULTS

The live birth rate (LBR) of SM group (30.7%) is lower than that of the FM group (43.6%) (p < 0.01). After adjustment by logistic regression, the second marriage group (OR = 1.269, 95%CI 1.031-1.562, p = 0.025) were independent factors associated with the outcome of live birth. After propensity score matching (PSM), the live birth rate of SM group (28.7%) is lower than the FM group (35.9%) (0 = 0.011).

CONCLUSION

The SM family experience higher levels of social and psychological pressure, which lead to lower level of LBR than FM family.

Association of unemployment and increased depressive symptoms with all-cause mortality: follow-up study of a cardiovascular prevention programme

Unemployment has been associated with increased risk of cardiovascular disease (CVD) and all-cause mortality. However, factors behind this association remain unsettled. A primary care CVD prevention programme was conducted in two Finnish towns in 2005-07. Of the participants (n = 4450), a cohort of apparently healthy CVD risk subjects belonging to the labour force (n = 1487) was identified. Baseline depressive symptoms were assessed by Beck's Depression Inventory. Data on employment status and mortality were obtained from official statistics. The effect of employment status and depressive symptoms on all-cause mortality after a median follow-up of 15 years was estimated in models adjusted for age, sex, body mass index, non-high-density lipoprotein cholesterol, physical activity, alcohol use, current smoking, glucose metabolism, and hypertension. In comparison to employed non-depressive subjects, fully adjusted hazard ratio (HR) for all-cause mortality was 3.53 (1.90-6.57) in unemployed subjects with increased depressive symptoms, 1.26 (0.68-2.34) in unemployed non-depressive subjects, and 1.09 (0.63-1.90) in employed depressive subjects. Factors independently associated with mortality were unemployment with increased depressive symptoms [HR 3.56 (95% CI 1.92-6.61)], screen-detected diabetes [HR 2.71 (95% CI 1.59-4.63)], current smoking [HR 1.77 (95% CI 1.19-2.65)], and higher age [HR 1.10 (95% CI 1.05-1.15)]. Unemployment in itself was not associated with all-cause mortality. If unemployment was accompanied with increased depressive symptoms, risk of death was significantly elevated.

Effectiveness of psychological therapies for depression and anxiety in atypical dementia

INTRODUCTION

People with dementia may benefit from psychological therapies for depression or anxiety, but evidence of their effectiveness in atypical dementia is limited.

METHODS

Using electronic health-care records of > 2 million people who attended psychological therapy services in England between 2012 and 2019, we examined pre-post therapy symptom changes and compared therapy outcomes among 523 people with atypical dementia, a matched cohort without dementia, and 1157 people with typical dementia.

RESULTS

People with atypical dementia experienced reductions in depression (Cohen d = -0.92 [-1.05 to -0.79]) and anxiety (d = -0.85 [-0.98 to -0.73]) symptoms. They had similar odds of improvement than people with typical dementia (odds ratio [OR] = 1.07, 95% confidence interval [CI]: 0.85 to 1.34), but lower odds than people living without dementia (OR = 0.70, 95% CI: 0.53 to 0.91). Reasons for discharge were similar between all groups.

DISCUSSION

People with atypical dementia may benefit from primary care psychological therapies, but further research is needed to explore necessary adaptations.

HIGHLIGHTS

Talking therapies for depression and anxiety may be beneficial for people with atypical dementia. Being younger and having a lower socioeconomic background are associated with poorer outcomes. Receiving more treatment sessions and shorter waiting times are associated with better outcomes.

Mind-Body Medicine in the Treatment of Depression: A Narrative Review of Efficacy, Safety and Mechanisms

PURPOSE OF THE REVIEW

This narrative review examines the efficacy, mechanisms and safety of mind-body medicine (MBM) in the treatment of depression. We reviewed the potential effects of various MBM interventions such as yoga, tai chi, qigong, mindfulness-based interventions and nutrition on clinical and subthreshold depressive symptoms.

RECENT FINDINGS

Current studies indicate a growing interest in the use of MBM for psychiatric disorders, including depression. MBM interventions demonstrate efficacy in reducing depressive symptoms with fewer adverse effects and costs compared to pharmacological treatments. MBM has significant potential to improve mental health outcomes for depression. These interventions encourage self-care and stress management through behavioural, exercise, relaxation and nutritional approaches. While existing data are promising, further, more rigorous studies are required to confirm long-term effectiveness and to determine the role of MBM in comprehensive depression treatment strategies.

The public health significance of prior homelessness: findings on multimorbidity and mental health from a nationally representative survey

AIMS

The associations of prior homelessness with current health are unknown. Using nationally representative data collected in private households in England, this study aimed to examine Common Mental Disorders (CMDs), physical health, alcohol/substance dependence, and multimorbidities in people who formerly experienced homelessness compared to people who never experienced homelessness.

METHODS

This cross-sectional study utilised data from the 2007 and 2014 Adult Psychiatric Morbidity Surveys. Former homelessness and current physical health problems were self-reported. Current CMDs, alcohol dependence and substance dependence were ascertained using structured validated scales. Survey-weighted logistic regression was used to compare multimorbidities (conditions in combination) for participants who formerly experienced homelessness with those who had never experienced homelessness, adjusting for sociodemographic characteristics, smoking status and adverse experiences. Population attributable fractions (PAFs) were calculated.

RESULTS

Of 13,859 people in the sample, 535 formerly experienced homelessness (3.6%, 95% CI 3.2-4.0). 44.8% of people who formerly experienced homelessness had CMDs (95% CI 40.2-49.5), compared to 15.0% (95% CI 14.3-15.7) for those who had never experienced homelessness. There were substantial associations between prior homelessness and physical multimorbidity (adjusted odds ratio [aOR] 1.98, 95% CI 1.53-2.57), CMD-physical multimorbidity (aOR 3.43, 95% CI 2.77-4.25), CMD-alcohol/substance multimorbidity (aOR 3.53, 95% CI 2.49-5.01) and trimorbidity (CMD-alcohol/substance-physical multimorbidity) (aOR 3.26, 95% CI 2.20-4.83), in models adjusting for sociodemographic characteristics and smoking. After further adjustment for adverse experiences, associations attenuated but persisted for physical multimorbidity (aOR 1.40, 95% CI 1.10-1.79) and CMD-physical multimorbidity (aOR 1.55, 95% CI 1.20-2.00). The largest PAFs were observed for CMD-alcohol/substance multimorbidity (17%) and trimorbidity (16%).

CONCLUSIONS

Even in people currently rehoused, marked inequities across multimorbidities remained evident, highlighting the need for longer-term integrated support for people who have previously experienced homelessness.

The Work and Social Adjustment Scale (WSAS): An investigation of reliability, validity, and associations with clinical characteristics in psychiatric outpatients

OBJECTIVE

This study, the first to assess the reliability and validity of the Work and Social Assessment Scale (WSAS) in Norwegian routine mental health care, examines differences in functional impairment based on sick leave status, psychiatric diagnosis, and sex.

METHOD

Including 3573 individuals from community mental health services (n1 = 1157) and a psychiatric outpatient clinic (n2 = 2416), exploratory factor analysis (EFA) on subsample 1 and confirmatory factor analysis (CFA) on subsample 2 were utilized to replicate the identified factor structure.

RESULTS

EFA supported a one-factor model, replicated by the CFA, with high internal consistency (α = .82, ω = .81). Patients on sick leave reported greater impairments in all aspects of functioning, except for relationships, with the largest effect size observed in the reported ability to work (d = .39). Psychiatric outpatients with major depressive disorder were associated with difficulties in home management, private leisure activities, and forming close relationships. Patients with attention-deficit/hyperactivity disorder reported less impairment than those with other disorders. Patients with personality disorders reported more relationship difficulties than those with PTSD, ADHD, and anxiety. No differences were found in the perceived ability to work between diagnoses. Women had a higher impairment in private leisure activities, whereas men reported more impairment in relationships.

CONCLUSION

The demonstrated reliability and validity suggest that WSAS is a valuable assessment tool in Norwegian routine mental health care. Variations in functional impairment across sick leave status, sex, and psychiatric diagnoses highlight the importance of integrating routine assessments of functional impairment into mental health care practices. Future research should combine WSAS with register data to allow for a broader understanding of treatment effectiveness, emphasizing improvements in functional outcomes alongside symptom alleviation.

Association between neighborhood socioeconomic status and healthcare utilization among individuals with a first diagnosis of major depressive disorder in primary care in the Stockholm region

BACKGROUND

Population-based surveys suggest that low socioeconomic status (SES) is associated with higher prevalence of depressive symptoms, while their healthcare utilization is not necessarily higher.

OBJECTIVE

To investigate the association between neighborhood socioeconomic status (NSES) and healthcare utilization among individuals diagnosed with major depressive disorder (MDD).

METHOD

This was a retrospective longitudinal study of all adults with a first MDD diagnosis within primary care during 2010-2018. NSES was defined by the household area of residence using the Mosaic™ classification. Outcomes were AD (antidepressants) (N06A) dispensation and psychiatric outpatient visit, both of which are outlined as options in depression guidelines. Cox multivariable regression was used for the time to event analyses.

RESULTS

A total of 117,193 individuals were included, of which 87,499 (75 %) were dispensed an AD and 35,989 (31 %) had a recorded psychiatric outpatient visit. Low NSES was associated with lower rate of AD dispensation in the first-year post-diagnosis (HR: 0.95, 95 % CI: 0.93-0.96, p < 0.001) and higher rate of psychiatric visit (HR: 1.10, 95 % CI: 1.07-1.12, p < 0.001) compared with high NSES.

LIMITATIONS

Data sources have high coverage. A minority of psychiatric care provided by non-publicly financed providers was not included. It was not possible to adjust for depression severity.

CONCLUSION

Socioeconomic status as measured by the neighborhood of residency was associated with AD dispensation and psychiatric outpatient visit in MDD, also in a healthcare system with virtually free access. This is of relevance for clinical practice, considering the focus on equity of care and the increase in depression prevalence worldwide.

Long-term effects of fine particulate matter components on depression among middle-aged and elderly adults in China: A nationwide cohort study

BACKGROUND

Fine particulate matter (PM2.5) has been implicated in various health concerns. However, a comprehensive understanding of the specific PM2.5 components affecting depression remains limited.

METHODS

This study conducted a Cox proportional-hazards model to assess the effect of PM2.5 components on the incidence of depression based on the China Health and Retirement Longitudinal Study (CHARLS). Participants with 10-item Center for Epidemiologic Studies Depression Scale (CESD-10) score of 10 or higher were classified as exhibiting depression.

RESULTS

Our findings demonstrated a significant positive correlation between long-term exposure to black carbon (BC), sulfate (SO42-), and organic matter (OM) components of PM2.5 and the prevalence of depression. Per 1 Interquartile Range (IQR) increment in 3-year average concentrations of BC, OM, and SO42- were associated with the hazard ratio (HR) of 1.54 (95 % confidence intervals (CI): 1.44, 1.64), 1.24 (95%CI: 1.16, 1.34) and 1.25 (95%CI: 1.16, 1.35). Notably, females, younger individuals, those with lower educational levels, urban residents, individuals who were single, widowed, or divorced, and those living in multi-story houses exhibited heightened vulnerability to the adverse effects of PM2.5 components on depression.

LIMITATIONS

Firstly, pollutant data is confined to subjects' fixed addresses, overlooking travel and international residence history. Secondly, the analysis only incorporates five fine particulate components, leaving room for further investigation into the remaining fine particulate components in future studies.

CONCLUSIONS

This study provides robust evidence supporting the detrimental impact of PM2.5 components on depression. The identification of specific vulnerable populations contributes to a deeper understanding of the underlying mechanisms involved in the relationship between PM2.5 components and depression.

Differences in psychological treatment outcomes by ethnicity and gender: an analysis of individual patient data

PURPOSE

There are discrepancies in mental health treatment outcomes between ethnic groups, which may differ between genders. NHS Talking Therapies for anxiety and depression provide evidence-based psychological therapies for common mental disorders. This study examines the intersection between ethnicity and gender as factors associated with psychological treatment outcomes. Aims were to explore by gender: (1) differences in psychological treatment outcomes for minoritized ethnic people compared to White-British people, (2) whether differences are observed when controlling for clinical and socio-demographic factors associated with outcomes, and (3) whether organization-level factors moderate differences in outcomes between ethnic groups.

METHODS

Patient data from eight NHS Talking Therapies for anxiety and depression services (n = 98,063) was used to explore associations between ethnicity and outcomes, using logistic regression. Stratified subsamples were used to separately explore factors associated with outcomes for males and females.

RESULTS

In adjusted analyses, Asian (OR = 0.82 [95% CI 0.78; 0.87], p < .001, 'Other' (OR = 0.79 [95%CI 0.72-0.87], p < .001) and White-other (0.93 [95%CI 0.89-0.97], p < .001) ethnic groups were less likely to reliably recover than White-British people. Asian (OR = 1.48 [95% CI 1.35-1.62], p < .001), Mixed (OR = 1.18 [95% CI 1.05-1.34], p = .008), 'Other' (OR = 1.60 [95% CI 1.38-1.84], p < .001) and White-other (OR = 1.18 [95% CI 1.09-1.28], p < .001) groups were more likely to experience a reliable deterioration in symptoms. Poorer outcomes for these groups were consistent across genders. There was some evidence of interactions between ethnic groups and organization-level factors impacting outcomes, but findings were limited.

CONCLUSIONS

Across genders, Asian, 'Other' and White-other groups experienced worse treatment outcomes across several measures in adjusted models. Reducing waiting times or offering more treatment sessions might lead to increased engagement and reduced drop-out for some patient groups.

The differential role of socioeconomic status dimensions in depressive symptoms of aging adults: data from the Hamburg City Health cohort Study

Background

Socioeconomic status (SES) has consistently been associated with depressive symptoms, however, it remains unclear which subset of SES variables is most relevant to the development of depressive symptoms. This study determined a standardized SES-Index to test the relationship of its sub-dimensions with depressive symptoms.

Methods

HCHS data (N = 10,000; analysis sample n = 8,400), comprising participants 45+ years of age, was used. A standardized approach to quantify SES was employed. Depressive symptoms were quantified using the Patient Health Questionnaire-9 (PHQ-9). Using multiple linear regression models, PHQ-9-scores were modeled as a function of age and sex, and (1a) total SES-Index score versus (1b) its three sub-dimension scores (education, occupational status, income). Models were compared on explained variance and goodness of fit. We determined risk ratios (RR, concerning a PHQ-9 sum score ≥ 10) based on (low, middle, high; 2a) SES-Index scores and (2b) the sub-dimension scores, with groups further differentiated by sex and age (45-64 versus 65+). We distinguished between the total SES-Index score and its three sub-dimension scores to identify relevant SES sub-dimensions in explaining PHQ-9-variability or risk of depression.

Results

Among all regression models (total explained variance 4-6%), income explained most variance, but performance of the SES-Index was comparable. Low versus high income groups showed the strongest differences in depressive trends in middle-aged females and males (RRs 3.57 and 4.91). In older age, this result was restricted to females (RR ≈ 2). Middle-aged males (versus females) showed stronger discrepancies in depressive trends pertaining to low versus high SES groups. In older age, the effect of SES was absent. Education was related to depressive trends only in middle-aged females and males. In an exploratory analysis, marital status and housing slightly increased model fit and explained variance while including somatic symptoms lead to substantial increases (R2 adj = 0.485).

Conclusion

In line with previous research, the study provides evidence for SES playing a significant role in depressive symptoms in mid to old age, with income being robustly linked to depressive trends. Overall, the relationship between SES and depressive trends appears to be stronger in males than females and stronger in mid compared to old age.

Efficacy and safety of Chinese patent medicines combined with antidepressants for treatment of depression in adults: A multiple-treatment meta-analysis

BACKGROUND

Combinations of Chinese patent medicines (CPM) with antidepressants (including selective serotonin reuptake inhibitors (SSRI), selective serotonin-norepinephrine reuptake inhibitors (SNRI), tricyclic antidepressants (TCA), and noradrenergic and specific serotonergic antidepressants (NaSSA)) are frequently utilized for treating depression in adults. However, the efficacy and safety of these combination treatments remain to be established.

METHODS

Systematic search was conducted in seven electronic databases, regulatory websites and international registers of trials from 1994 to 2023 that included adult patients with depressive disorders who received CPM combined with antidepressants. The Multiple-Treatment Meta-Analysis (MTMA) was conducted using a random effects model with Stata/MP17 and R4.3.5 software. Primary outcomes were total efficacy rate, Hamilton Depression Scale (HAMD) score, and Treatment Emergency Symptom Scale (TESS) score. Secondary outcomes included brain-derived neurotrophic factor (BDNF) levels.

RESULTS

A total of 146 randomized controlled trials (13,754 participants: 6929 in intervention and 6825 in control groups) were included. For total effective rate, Multiple-Treatment Meta-Analysis results showed that the overall effect of combined intervention was better compared with antidepressants alone, where Jieyuanshenkeli (JYASKL) presented the optimal option for improving total efficacy (OR = 5.39, 95% CI [2.60, 11.18], SUCRA = 84.50%). In reduding the HAMD, Shuganjieyujiaonang (SGJYJN) was most likely to reduce the HAMD score (SMD = -2.20, 95% CI [-3.06, -1.33], SUCRA = 86.10%), Jieyuanshenkeli (JYASKL),Tianewangbuxindan (TWBXD), Shuyukeli (SYKL), Anshenbuxinwan (ASBXW) combination intervention did not appear to be statistically superior to antidepressants alone. In theTreatment Emergency Symptom Scale (TESS), Wulinjiaonang induced the most significant reduction in TESS score (SMD = -1.98, 95% CI [-3.59, -0.36], SUCRA = 90.40%). Tianmengjiaonang (TMJN) + Antidepressants(AD) (SUCRA = 88.30%) displayed the highest scores in increasing the levels of BDNF, although not statistically significant compared to Antidepressants(AD) alone (SMD = 1.23, 95% CI [0.90, 1.55]).

CONCLUSION

Combinations of CPM and antidepressants showed superior efficacy over antidepressants alone. The optimal combinations were determined as Shuganjieyu Jiaonang (SGJYJN)/SSRIs and Jieyuanshenkeli (JYASKL)/SSRIs. In terms of safety, results showed that combination therapy did not show better TESS efficacy than antidepressants alone.Although some of the combination interventions were not superior than antidepressants alone in reducing HAMD scores,our findings provide a potentially significant alternative option for clinical complementary therapy. However, these results require further validation through larger sample sizes, multicenter randomized controlled trials, and real-world data.

Predictors of primary care psychological therapy outcomes for depression and anxiety in people living with dementia: evidence from national healthcare records in England

BACKGROUND

Psychological therapies can be effective in reducing symptoms of depression and anxiety in people living with dementia (PLWD). However, factors associated with better therapy outcomes in PLWD are currently unknown.

AIMS

To investigate whether dementia-specific and non-dementia-specific factors are associated with therapy outcomes in PLWD.

METHOD

National linked healthcare records were used to identify 1522 PLWD who attended psychological therapy services across England. Associations between various factors and therapy outcomes were explored.

RESULTS

People with frontotemporal dementia were more likely to experience reliable deterioration in depression/anxiety symptoms compared with people with vascular dementia (odds ratio 2.98, 95% CI 1.08-8.22; P = 0.03) or Alzheimer's disease (odds ratio 2.95, 95% CI 1.15-7.55; P = 0.03). Greater depression severity (reliable recovery: odds ratio 0.95, 95% CI 0.92-0.98, P < 0.001; reliable deterioration: odds ratio 1.73, 95% CI 1.04-2.90, P = 0.04), lower work and social functioning (recovery: odds ratio 0.98, 95% CI 0.96-0.99, P = 0.002), psychotropic medication use (recovery: odds ratio 0.67, 95% CI 0.51-0.90, P = 0.01), being of working age (recovery: odds ratio 2.03, 95% CI 1.10-3.73, P = 0.02) and fewer therapy sessions (recovery: odds ratio 1.12, 95% CI 1.09-1.16, P < 0.001) were associated with worse therapy outcomes in PLWD.

CONCLUSIONS

Dementia type was generally not associated with outcomes, whereas clinical factors were consistent with those identified for the general population. Additional support and adaptations may be required to improve therapy outcomes in PLWD, particularly in those who are younger and have more severe depression.

The Importance of Conducting Practice-oriented Research with Underserved Populations

There has been a growing emphasis on dissemination of empirically supported treatments. Dissemination, however, should not be restricted to treatment. It can and, in the spirit of the scientific-practitioner model, should also involve research. Because it focuses on the investigation of clinical routine as it takes place in local settings and because it can involve the collaboration of several stakeholders, practice-oriented research (POR) can be viewed as an optimal research method to be disseminated. POR has the potential of addressing particularly relevant gaps of knowledge and action when implemented in regions of the world that have limited resources for or experiences with empirical research, and/or in clinical settings that are serving clinical populations who are not typically receiving optimal mental care services - specifically, individuals in rural and inner cities that have limited economic and social resources. The establishment and maintenance of POR in such regions and/or settings, however, come with specific obstacles and challenges. Integrating the experiences acquired from research conducted in various continents (Africa, Europe, Latin America, and North America), the goal of this paper is to describe some of these challenges, strategies that have been implemented to address them, as well as new possible directions to facilitate the creation and growth of POR. It also describes how these challenges and ways to deal with them can provide helpful lessons for already existing POR infrastructures.

Men's Depression and Anxiety: Contributing Factors and Barriers to Intervention

BACKGROUND

Urban, ethnically/racially diverse, impoverished men are predisposed to experience unaddressed depression and anxiety. The overlap of these factors creates significant mental health inequity.

AIMS

This study sought to capture men's impressions of the factors that contributed to their experience of depression and anxiety as well as barriers that they experienced in pursuing intervention.

METHODS

Using community-based participatory research, in the context of long-term partnerships between a department of nursing and three urban, racially/ethnically diverse, and impoverished neighborhoods, the researchers recruited 50 men ages 23-83 years. Data were collected via six homogeneous, Zoom-based focus groups composed of Black, Hispanic, and White men, respectively.

RESULTS

The men identified multiple themes pertaining to modifiable and non-modifiable contributing factors that played a role in their development of depression and anxiety as well as barriers related to stigma, resource issues, and a lack of knowledge of mental illness that they faced when seeking intervention.

CONCLUSIONS

Understanding men's perspectives on the contributing factors and barriers to mental health intervention can provide an evidence base with which to address mental health inequity via tailored care, policy, and research agendas.

Different components of cognitive-behavioral therapy affect specific cognitive mechanisms

Psychological therapies are among the most effective treatments for common mental health problems-however, we still know relatively little about how exactly they improve symptoms. Here, we demonstrate the power of combining theory with computational methods to parse effects of different components of cognitive-behavioral therapies onto underlying mechanisms. Specifically, we present data from a series of randomized-controlled experiments testing the effects of brief components of behavioral and cognitive therapies on different cognitive processes, using well-validated behavioral measures and associated computational models. A goal setting intervention, based on behavioral activation therapy activities, reliably and selectively reduced sensitivity to effort when deciding how to act to gain reward. By contrast, a cognitive restructuring intervention, based on cognitive therapy materials, reliably and selectively reduced the tendency to attribute negative everyday events to self-related causes. The effects of each intervention were specific to these respective measures. Our approach provides a basis for beginning to understand how different elements of common psychotherapy programs may work.

Long-term depressive symptom trajectories and related baseline characteristics in primary care patients: Analysis of the PsicAP clinical trial

BACKGROUND

There is heterogeneity in the long-term trajectories of depressive symptoms among patients. To date, there has been little effort to inform the long-term trajectory of symptom change and the factors associated with different trajectories. Such knowledge is key to treatment decision-making in primary care, where depression is a common reason for consultation. We aimed to identify distinct long-term trajectories of depressive symptoms and explore pre-treatment characteristics associated with them.

METHODS

A total of 483 patients from the PsicAP clinical trial were included. Growth mixture modeling was used to identify long-term distinct trajectories of depressive symptoms, and multinomial logistic regression models to explore associations between pre-treatment characteristics and trajectories.

RESULTS

Four trajectories were identified that best explained the observed response patterns: "recovery" (64.18%), "late recovery" (10.15%), "relapse" (13.67%), and "chronicity" (12%). There was a higher likelihood of following the recovery trajectory for patients who had received psychological treatment in addition to the treatment as usual. Chronicity was associated with higher depressive severity, comorbidity (generalized anxiety, panic, and somatic symptoms), taking antidepressants, higher emotional suppression, lower levels on life quality, and being older. Relapse was associated with higher depressive severity, somatic symptoms, and having basic education, and late recovery was associated with higher depressive severity, generalized anxiety symptoms, greater disability, and rumination.

CONCLUSIONS

There were different trajectories of depressive course and related prognostic factors among the patients. However, further research is needed before these findings can significantly influence care decisions.

Short-Term Exposure to PM2.5 Chemical Components and Depression Outpatient Visits: A Case-Crossover Analysis in Three Chinese Cities

BACKGROUND

The association between specific chemical components of PM2.5 and depression remains largely unknown.

METHODS

We conducted a time-stratified case-crossover analysis with a distributed lag nonlinear model (DLNM) to evaluate the relationship of PM2.5 and its chemical components, including black carbon (BC), organic matter (OM), sulfate (SO42-), nitrate (NO3-), and ammonium (NH4+), with the depression incidence. Daily depression outpatients were enrolled from Huizhou, Shenzhen, and Zhaoqing.

RESULTS

Among 247,281 outpatients, we found the strongest cumulative effects of PM2.5 and its chemical components with the odd ratios (ORs) of 1.607 (95% CI: 1.321, 1.956) and 1.417 (95% CI: 1.245, 1.612) at the 50th percentile of PM2.5 and OM at lag 21, respectively. Furthermore, the ORs with SO42- and NH4+ at the 75th percentile on the same lag day were 1.418 (95% CI: 1.247, 1.613) and 1.025 (95% CI: 1.009, 1.140). Relatively stronger associations were observed among females and the elderly.

CONCLUSIONS

Our study suggests that PM2.5 and its chemical components might be important risk factors for depression. Reducing PM2.5 emissions, with a particular focus on the major sources of SO42- and OM, might potentially alleviate the burden of depression in South China.

Sociodemographic and clinical predictors of adherence to antidepressants in depressive disorders: a systematic review with a meta-analysis

Introduction: Current evidence reveals concerning rates of non-adherence to antidepressant treatment, possibly influenced by various relevant determinants such as sociodemographic factors or those related to the health system and their professionals. The aim of this paper is to review the scientific evidence on sociodemographic and clinical predictors of adherence to pharmacological treatment in patients diagnosed with a depressive disorder. Methods: a systematic review (SR) was conducted. The search for a previous SR was updated and de novo searches were performed in Medline, EMBASE, Web of Science (WoS) and PsycInfo (last 10 years). The risk of bias was assessed using the Cochrane tool for non-randomized studies-of Exposure (ROBINS-E). Meta-analyses were conducted. Results: Thirty-nine studies (n = 2,778,313) were included, 24 of them in the meta-analyses. In the initiation phase, no association of adherence was found with any of the predictors studied. In the implementation and discontinuation phases, middle-aged and older patients had better adherence rates and lower discontinuation rates than younger ones. White patients adhered to treatment better than African-American patients. Discussion: Age and ethnicity are presented as the predictive factors of pharmacological adherence. However, more research is needed in this field to obtain more conclusive results on other possible factors.

Risk Factors for Depression Among Middle-Aged to Older People Living With HIV in Lima, Peru

INTRODUCTION

Depression is prevalent among aging people living with HIV (PLWH) worldwide. We sought to identify depression risk factors among a group of middle-aged and older PLWH in Lima, Peru.

MATERIALS AND METHODS

We assessed risk factors for depression among PLWH over age 40 receiving care in an HIV clinic in Lima, Peru. The Patient Health Questionnaire-9 (PHQ-9) was administered. We performed descriptive statistics and logistic regression analyses.

RESULTS

Mean age was 51.7 ± 7.7 years with 15.3% females. One-quarter of participants had depression with higher frequency in females. Risk factors that significantly increased the risk of depression included female sex (adjusted prevalence ratio [aPR] = 2.19 [95%CI 1.07-4.49]), currently smoking (aPR = 2.25 [95%CI 1.15-4.43]), and prior opportunistic infection (aPR = 2.24 [95%CI 1.05-4.76]).

DISCUSSION

Our study demonstrates that PLWH who are female, current smokers, or had an opportunistic infection have higher risk of depression. Identifying PLWH at-risk for depression is key to early mental health interventions.

Prognostic Risk Factors in Randomized Clinical Trials of Face-to-Face and Internet-Based Psychotherapy for Depression: A Systematic Review and Meta-Regression Analysis

Importance

Variables such as severe symptoms, comorbidity, and sociodemographic characteristics (eg, low educational attainment or unemployment) are associated with a poorer prognosis in adults treated for depressive symptoms. The exclusion of patients with a poor prognosis from RCTs is negatively associated with the generalizability of research findings.

Objective

To compare the prognostic risk factors (PRFs) in patient samples of RCTs of face-to-face therapy (FTF) and internet-based therapy (IBT) for depression.

Data Sources

PsycINFO, Cochrane CENTRAL, and reference lists of published meta-analyses were searched from January 1, 2000, to December 31, 2021.

Study Selection

RCTs that compared FTF (individual or group therapy) and IBT (guided or self-guided interventions) against a control (waitlist or treatment as usual) in adults with symptoms of depression were included.

Data Extraction and Synthesis

Data were extracted by 2 independent observers. The Cochrane revised risk-of-bias tool was used to assess the risk of bias. The study was preregistered with OSF Registries and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.

Main Outcomes and Measures

The primary outcome was the standardized mean difference (Hedges g effect size) in depressive symptoms at treatment termination (assessed with standard patient self-report questionnaires), with a positive standardized mean difference indicating larger improvements in the intervention compared with those in the control group. Meta-regression analyses were adjusted for the type of control group. Three preregistered and 2 exploratory sensitivity analyses were conducted. A prognostic risk index (PROG) was created that calculated the sum of 12 predefined individual indicators, with scores ranging from 0 to 12 and higher scores indicating that a sample comprised patients with poorer prognoses.

Results

This systematic review and meta-regression analysis identified 105 eligible RCTs that comprised 18 363 patients. In total, 48 studies (46%) examined FTF, and 57 studies (54%) examined IBT. The PROG was significantly higher in the RCTs of FTF than in the RCTs of IBT (FTF: mean [SD], 3.55 [1.75]; median [IQR], 3.5 [2.0-4.5]; IBT: mean [SD], 2.27 [1.66]; median [IQR], 2.0 [1.0-3.5]; z = -3.68, P < .001; Hedges g = 0.75; 95% CI, 0.36-1.15). A random-effects meta-regression analysis found no association of the PROG with the effect size. Sensitivity analyses with outliers excluded and accounting for risk of bias or small-study effects yielded mixed results on the association between the PROG and effect size.

Conclusions and Relevance

The findings of this systematic review and meta-regression analysis suggest that samples of RCTs of FTF vs IBT differ with regard to PRFs. These findings have implications for the generalizability of the current evidence on IBT for depression. More RCTs of internet-based interventions with clinically representative samples are needed, and the reporting of PRFs must be improved.

Hypertension, socioeconomic status and depressive and anxiety disorders: a cross-sectional study of middle-aged and older Chinese women

OBJECTIVES

To investigate the association of hypertension with depressive and anxiety disorders in middle-aged and older Chinese women, and to further assess whether the association was influenced by socioeconomic status (SES).

DESIGN

Nationwide cross-sectional study.

SETTING

Six provinces of the eastern, central and western regions of China.

PARTICIPANTS

Women aged 40-70 years were included by a multistage stratified random cluster sampling in 2018 (N=9900).

PRIMARY OUTCOME MEASURES

Depressive and anxiety disorders were measured by the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, respectively. Logistic regression models were used to evaluate the OR and 95% CI for hypertension and the odds of depressive and anxiety disorders.

RESULTS

18.5% of participants reported having hypertension; 20.9% and 15.3% of women experienced depressive and anxiety disorders, respectively. After adjusting for potential confounders, women diagnosed with hypertension were more likely to have depressive (OR=1.27, 95% CI 1.11 to 1.45) and anxiety disorders (OR=1.48, 95% CI 1.28 to 1.71) than those without hypertension. Stratified analyses demonstrated that hypertension was significantly associated with higher odds of depressive disorders in women living in rural areas (OR=1.34, 95% CI 1.13 to 1.59), with lower levels of education (OR=1.28, 95% CI 1.12 to 1.46) and with average monthly household income <¥3000 (OR=1.33, 95% CI 1.12 to 1.59), while hypertension was significantly correlated with increased odds of anxiety disorders in women living in urban (OR=1.41, 95% CI 1.12 to 1.79) and rural areas (OR=1.53, 95% CI 1.27 to 1.84), with lower levels of education (OR=1.47, 95% CI 1.27 to 1.70), and with average monthly household income <¥3000 (OR=1.45, 95% CI 1.20 to 1.75) and ≥¥3000 (OR=1.49, 95% CI 1.18 to 1.86).

CONCLUSIONS

Hypertension was associated with increased odds of depressive and anxiety disorders among middle-aged and older women, especially in those with low SES. Effective strategies and actions for identification and management of hypertension and depressive and anxiety disorders are needed.

Prevalence and associations of poor mental health in the third year of COVID-19: U.S. population-based analysis from 2020 to 2022

BACKGROUND

Poorer mental health was found early in the COVID-19 pandemic, yet mental health in the third year of COVID-19 has not been assessed on a general adult population level in the United States.

METHODS

We used a nationally representative cross-sectional survey (Health Information National Trends Survey, HINTS 5 2020 n = 3,865 and HINTS 6 2022 n = 6,252). The prevalence of poor mental health was examined using a Patient Health Questionnaire-4 scale in 2020 and 2022. We also investigated the factors associated with poor mental health in 2022 using a weighted multivariable logistic regression adjusting for sociodemographic and health status characteristics to obtain the odds ratio (OR).

OUTCOMES

The prevalence of poor mental health in adults increased from 2020 to 2022 (31.5% vs 36.3 %, p = 0.0005). U.S. adults in 2022 were 1.28 times as likely to have poor mental health than early in the pandemic. Moreover, individuals with food insecurity, housing instability, and low income had greater odds of poor mental health (ORs=1.78-2.55). Adults who were females, non-Hispanic Whites, or age 18-64 years were more likely to have poor mental health (ORs=1.46-4.15).

INTERPRETATION

Mental health of U.S. adults worsened in the third year of COVID-19 compared to the beginning of the pandemic.

The influence of peer non-suicidal self-harm on young adults' urges to self-harm: experimental study

OBJECTIVE

To test the hypothesis that exposure to peer self-harm induces adolescents' urges to self-harm and that this is influenced by individual suggestibility.

METHODS

We recruited 97 UK-based adults aged 18-25 years with a recent history of self-harm, measuring baseline suggestibility (Resistance to Peer Influence; RPI) and perceived ability to control urges to self-harm (using an adapted item from the Self-Efficacy to Resist Suicidal Action scale; SEASA) before and after two self-harm vignettes featuring named peers from the participant's social network (to simulate exposure to peer non-suicidal self-harm) and after a wash-out exposure. We used paired t-tests to compare mean SEASA scores pre- and post-exposure, and linear regression to test for an association between RPI and change in SEASA scores pre- and post-exposure.

RESULTS

Perceived ability to control urges to self-harm was significantly reduced following exposure to peer self-harm (t(96) = 4.02, p < 0.001, mean difference = 0.61; 95% CI = 0.31, 0.91), but was not significantly different from baseline after exposure to a wash-out. We found no association between suggestibility and change in urges to self-harm after exposure to peer self-harm.

CONCLUSION

Our findings support social influences on self-harm in a sample of young adults, regardless of their individual degree of suggestibility.

Trajectories of depression symptoms, anxiety symptoms and functional impairment during internet-enabled cognitive-behavioural therapy

Underlying classes capture differences between patient symptom trajectories during psychological therapy. This has not been explored for one-to-one internet-delivered therapy or functional impairment trajectories. Patients experiencing depression or anxiety received cognitive-behavioural therapy with a therapist using an online chat platform (N = 52,029). Trajectory classes of depression symptoms (PHQ9), anxiety symptoms (GAD7) and functional impairment (WSAS) were investigated using growth mixture modelling. Multinomial regressions tested associations between baseline variables and trajectory class. A four-class trajectory model was selected for each outcome, and these were highly similar. Each outcome showed three classes with initially moderate-severe symptoms or impairment: one demonstrated no change, one gradual improvement and one fast improvement. A fourth class had mild baseline scores and minimal improvement. In the moderate-severe classes, patients in the two with improvement were more likely to be employed and not to have obsessive-compulsive disorder. Fast improvement was likelier than gradual improvement or no change for patients with older age, no disability (e.g., physical, learning), or lower comorbid symptom or impairment scores. Associations with functional impairment classes were more similar to associations with depression classes than anxiety classes. Results were largely consistent with findings from face-to-face therapy. This study is an important step towards personalising therapy in terms of suitability and continuation.

Trajectories of depression and anxiety symptom severity during psychological therapy for common mental health problems

BACKGROUND

There is substantial variation in patient symptoms following psychological therapy for depression and anxiety. However, reliance on endpoint outcomes ignores additional interindividual variation during therapy. Knowing a patient's likely symptom trajectories could guide clinical decisions. We aimed to identify latent classes of patients with similar symptom trajectories over the course of psychological therapy and explore associations between baseline variables and trajectory class.

METHODS

Patients received high-intensity psychological treatment for common mental health problems at National Health Service Improving Access to Psychological Therapies services in South London (N = 16 258). To identify trajectories, we performed growth mixture modelling of depression and anxiety symptoms over 11 sessions. We then ran multinomial regressions to identify baseline variables associated with trajectory class membership.

RESULTS

Trajectories of depression and anxiety symptoms were highly similar and best modelled by four classes. Three classes started with moderate-severe symptoms and showed (1) no change, (2) gradual improvement, and (3) fast improvement. A final class (4) showed initially mild symptoms and minimal improvement. Within the moderate-severe baseline symptom classes, patients in the two showing improvement as opposed to no change tended not to be prescribed psychotropic medication or report a disability and were in employment. Patients showing fast improvement additionally reported lower baseline functional impairment on average.

CONCLUSIONS

Multiple trajectory classes of depression and anxiety symptoms were associated with baseline characteristics. Identifying the most likely trajectory for a patient at the start of treatment could inform decisions about the suitability and continuation of therapy, ultimately improving patient outcomes.

Predictors of transitioning to adult mental health services and associated costs: a cross-country comparison

BACKGROUND

Young people are at risk of falling through the care gap after leaving child and adolescent mental health services (CAMHS) despite an ongoing need for mental health support. Currently, little is known about the predictors of transitioning to adult mental health services (AMHS), and associated healthcare and societal costs as young people cross the transition boundary.

OBJECTIVE

To conduct a secondary data analysis exploring predictors of transitioning or falling through the gap and associated costs.

METHODS

Data were used from a longitudinal study, which followed young people from seven European countries for 2 years after reaching their CAMHS boundary. Predictors of transitioning (including sociodemographic and clinical variables) and longitudinal resource use were compared for 488 young people who transitioned to AMHS versus those who fell through the gap.

FINDINGS

Young people were more likely to transition to AMHS if they were severely ill. Those from Italy, the Netherlands and the UK were more likely to fall through the gap than transition to AMHS. Healthcare costs fell for all young people over the study, with a sharper decrease for those who fell through the gap.

CONCLUSIONS

Total healthcare costs fell for all participants, indicating that the intensity of mental health support reduces for all young people as they cross the CAMHS boundary, regardless of clinical need.

CLINICAL IMPLICATIONS

It is important that alternative forms of mental health support are available for young people who do not meet the AMHS care threshold but still have mental health needs after leaving CAMHS.

No benefit of antidepressants in inpatient treatment of depression. A longitudinal, quasi-experimental field study

RATIONALE

Antidepressants (AD) are mostly considered indispensable for the treatment of major depression. The vast majority of depressive inpatients are treated with AD. However, there is a growing body of studies indicating that the effectiveness of AD is greatly overestimated due to methodological issues with the AD efficacy studies (e.g., publication bias, unintentional unblinding, confusion between withdrawal symptoms and relapse).

OBJECTIVES

The benefit of the additional use of AD in the inpatient treatment of depression with intensive cognitive-behavioral therapy (CBT) has been investigated in a naturalistic design.

METHODS

Depressiveness was assessed using the Beck Depression Inventory (BDI-II) during a preliminary interview (T0), at admission (T1), at discharge (T2), and at a 6-month follow-up (T3). Two study phases were compared: During Phase A, AD were recommended in accordance with the German guideline. In Phase B, AD were no longer recommended, and they were only prescribed upon explicit request from patients. In phase A (N = 574), 60.3% of all patients were taking AD at discharge. In Phase B (N = 424), 27.9% of patients were on AD at discharge. Apart from the difference in AD usage, the two treatment conditions were similar, and the samples did not significantly differ in terms of age, sex, diagnoses, history of suicide attempts, comorbid anxiety disorders, and unemployment.

RESULTS

In both study phases, BDI-II scores were strongly decreased at T2 and T3, respectively, compared with T1. The BDI-II scores of the two phases did not differ at any of the measurement time points. Depression changes were similar in both phases. In sequential multiple regression analyses with the total sample, AD were no significant predictors for the reduction of depression at either T2 or T3.

CONCLUSIONS

The inpatient CBT was effective in depression. The effectiveness of CBT is not improved by the additional use of AD. The current prescribing practices of AD should be questioned.

Quality of Depression Care for Veterans Affairs Primary Care Patients with Experiences of Homelessness

BACKGROUND

Persons who experience homelessness (PEH) have high rates of depression and incur challenges accessing high-quality health care. Some Veterans Affairs (VA) facilities offer homeless-tailored primary care clinics, although such tailoring is not required, within or outside VA. Whether services tailoring enhances care for depression is unstudied.

OBJECTIVE

To determine whether PEH in homeless-tailored primary care settings receive higher quality of depression care, compared to PEH in usual VA primary care.

DESIGN

Retrospective cohort study of depression treatment among a regional cohort of VA primary care patients (2016-2019).

PARTICIPANTS

PEH diagnosed or treated for a depressive disorder.

MAIN MEASURES

The quality measures were timely follow-up care (3 + completed visits with a primary care or mental health specialist provider, or 3 + psychotherapy sessions) within 84 days of a positive PHQ-2 screen result, timely follow-up care within 180 days, and minimally appropriate treatment (4 + mental health visits, 3 + psychotherapy visits, 60 + days antidepressant) within 365 days. We applied multivariable mixed-effect logistic regressions to model differences in care quality for PEH in homeless-tailored versus usual primary care settings.

KEY RESULTS

Thirteen percent of PEH with depressive disorders received homeless-tailored primary care (n = 374), compared to usual VA primary care (n = 2469). Tailored clinics served more PEH who were Black, who were non-married, and who had low income, serious mental illness, and substance use disorders. Among all PEH, 48% received timely follow-up care within 84 days of depression screening, 67% within 180 days, and 83% received minimally appropriate treatment. Quality metric attainment was higher for PEH in homeless-tailored clinics, compared to PEH in usual VA primary care: follow-up within 84 days (63% versus 46%; adjusted odds ratio [AOR] = 1.61, p = .001), follow-up within 180 days (78% versus 66%; AOR = 1.51, p = .003), and minimally appropriate treatment (89% versus 82%; AOR = 1.58, p = .004).

CONCLUSIONS

Homeless-tailored primary care approaches may improve depression care for PEH.

Income inequalities beyond access to mental health care: a Dutch nationwide record-linkage cohort study of baseline disease severity, treatment intensity, and mental health outcomes

BACKGROUND

Existing literature shows low and unequal access to mental health treatment globally, resulting in policy efforts to promote access for vulnerable groups. Yet, there is little evidence about how inequalities develop once individuals start treatment. The greater use of mental health care among individuals with low income, such as in the Dutch system, might be driven by differences in need and might not necessarily lead to better treatment outcomes. In this study, we aimed to examine income inequalities in four stages of the mental health treatment pathway while adjusting for need.

METHODS

We constructed a nationwide retrospective cohort study, examining all patients aged older than 18 years with a first specialist mental health treatment record in the Netherlands between 2011 and 2016, excluding those who did not receive any treatment minutes. We linked patient-level data from treatment records to administrative data on income, demographics from municipal registries, and health insurance claims. We used multivariate models to estimate adjusted associations between household income quintile (standardised for household size) and outcomes characterising four stages of mental health treatment: severity at baseline assessment based on the Global Assessment of Functioning (GAF) score, treatment minutes received, functional improvement by the end of the initial record, and additional treatment in a subsequent record. Estimates were adjusted for patient need (97 categories of primary diagnosis and severity at baseline assessment measured by GAF) and demographic covariates.

FINDINGS

Our study population consisted of 951 530 adults with a first specialist mental health treatment record in the Netherlands between Jan 1, 2011, and Dec 31, 2016. Patients in our cohort were on average aged 45·0 years (range 19-107) and mostly female (529 859 [55·7%] women and 421 671 [44·3%] men; no ethnicity data were available). First, we found that patients with the lowest income had the greatest initial therapist-assessed disease severity (5·545 GAF points), which was 0·353 GAF points (95% CI 0·347-0·360) lower than those in the highest income quintile. Second, we found that the negative association between income and treatment minutes was reversed once we adjusted for diagnosis and severity at baseline, with patients with the lowest income receiving 1·8% fewer treatment minutes (95% CI 1·1-2·4) than those in the highest quintile. Third, those in the highest income quintile were 17·3 percentage points (95% CI 17·0-17·6) more likely to have functional improvements by the end of the initial record, compared with 25·8% of patients with an improvement in the lowest income quintile. Fourth, while 35·7% of patients in the lowest income quintile received additional treatment in a subsequent record, this was only 3·0 percentage points (95% CI 2·7-3·3) lower for those in the highest quintile. None of these patterns were explained by diagnosis, severity at baseline, or treatment minutes received.

INTERPRETATION

Disparities favourable to patients with a higher income persist through the different stages of mental health treatment. These differences highlight the limitations of solely focusing on improving access to care to reduce the mental health gap. Our findings call for a better understanding of the role of social environment and quality of care as complementary mechanisms explaining inequalities during mental health treatment.

Examining bi-directional change in sleep and depression symptoms in individuals receiving routine psychological treatment

BACKGROUND

Sleep disturbance is a common symptom of depression. There is conflicting evidence whether improvements in sleep might impact depressive symptoms, or whether treating the core depressive symptoms might improve sleep disturbance. This study explored the bi-directional impact of sleep and depressive symptom change among individuals receiving psychological treatment.

METHODS

Session-by-session change in sleep disturbance and depressive symptom severity scores were explored in patients receiving psychological therapy for depression from Improving Access to Psychological Therapies services in England. Bi-directional change in sleep disturbance and depressive symptoms was modelled using random-intercept cross-lagged panel models with items from the PHQ-9.

RESULTS

The sample included 17,732 adults that had received three or more treatment sessions. Both depressive symptoms and sleep disturbance scores decreased. Between initial timepoints, higher sleep disturbance was associated with lower depression scores, but after this point positive cross-lagged effects were observed for both the impact of sleep disturbance on later depressive symptoms, and depressive symptoms on later sleep disturbance scores. The magnitude of effects suggested depressive symptoms may have more impact on sleep than the reverse, and this effect was larger in sensitivity analyses.

CONCLUSIONS

Findings provide evidence that psychological therapy for depression results in improvements in core depressive symptoms and sleep disturbance. There was some evidence that depressive symptoms may have more impact on sleep disturbance scores at the next therapy session, than sleep disturbance does on later depressive symptoms. Targeting the core symptoms of depression initially may optimise outcomes, but further research is needed to elucidate these relationships.

Financial strain and depression in the U.S.: a scoping review

While the association between assets and depression has been established, less is known about the link between financial strain and depression. Given rising financial strain and economic inequity due to the COVID-19 pandemic, understanding the role that financial strain plays in shaping population depression in the United States is particularly salient. We conducted a scoping review of the peer-reviewed literature on financial strain and depression published from inception through January 19, 2023, in Embase, Medline via PubMed, and PsycINFO, PsycArticles, SocINDEX, and EconLit via Ebsco. We searched, reviewed, and synthesized the literature on longitudinal studies on financial strain and depression conducted in the United States. Four thousand and four unique citations were screened for eligibility. Fifty-eight longitudinal, quantitative articles on adults in the United States were included in the review. Eighty-three percent of articles (n = 48) reported a significant, positive association between financial strain and depression. Eight articles reported mixed results, featuring non-significant associations for some sub-groups and significant associations for others, one article was unclear, and one article reported no significant association between financial strain and depression. Five articles featured interventions to reduce depressive symptoms. Effective interventions included coping mechanisms to improve one's financial situation (e.g., mechanisms to assist in finding employment), to modify cognitive behavior (e.g., reframing mindset), and to engage support (e.g., engaging social and community support). Successful interventions were tailored to participants, were group-based (e.g., they included family members or other job seekers), and occurred over multiple sessions. While depression was defined consistently, financial strain was defined variably. Gaps in the literature included studies featuring Asian populations in the United States and interventions to reduce financial strain. There is a consistent, positive association between financial strain and depression in the United States. More research is needed to identify and test interventions that mitigate the ill effects of financial strain on population's mental health.

Psychological therapies for depression and cardiovascular risk: evidence from national healthcare records in England

AIMS

People with depression are up to 72% more at risk to develop cardiovascular disease (CVD) in their lifetime. Evidence-based psychotherapies are first-line interventions for the treatment of depression and are delivered nationally in England through the National Health Service via the Improving Access to Psychological Therapy (IAPT) primary care programme. It is currently unknown whether positive therapy outcomes may be associated with cardiovascular risk reduction. This study aimed to examine the association between psychotherapy outcomes for depression and incident CVD.

METHODS AND RESULTS

A cohort of 636 955 individuals who have completed a course of psychotherapy was built from linked electronic healthcare record databases of national coverage in England: the national IAPT database, the Hospital Episode Statistics (HES) database, and the HES-ONS (Office of National Statistics) mortality database. Multivariable Cox models adjusting for clinical and demographic covariates were run to estimate the association between reliable improvement from depression and the risk of subsequent incidence of cardiovascular events. After a median follow-up of 3.1 years, reliable improvement from depression symptoms was associated with a lower risk of new onset of any CVD [hazard ratio (HR): 0.88, 95% confidence interval (CI): 0.86, 0.89], coronary heart disease (HR: 0.89, 95% CI: 0.86, 0.92), stroke (HR: 0.88, 95% CI: 0.83, 0.94), and all-cause mortality (HR: 0.81, 95% CI: 0.78, 0.84). This association was stronger in the under 60 compared with the over 60 for all outcomes. Results were confirmed in sensitivity analyses.

CONCLUSION

Management of depression through psychological interventions may be associated with reduced risk of CVD. More research is needed to understand the causality of these associations.

Symptom-specific effects of counselling for depression compared to cognitive-behavioural therapy

BACKGROUND

Cognitive-behavioural therapy (CBT) and counselling for depression (CfD) are recommended first-line treatments for depression. While they approach change differently, there is little understanding of the impact those approaches have on change during treatment.

OBJECTIVES

This study aimed to identify whether CBT and CfD target different symptoms and explore the implications of modelling choices when quantifying change during treatment.

METHODS

Symptom-specific effects of treatment were identified using moderated network modelling. This was a retrospective cohort study of 12 756 individuals who received CBT or CfD for depression in primary/community care psychological therapy services in England. Change was modelled several ways within the whole sample and a propensity score matched sample (n=3446).

FINDINGS

CBT for depression directly affected excessive worry, trouble relaxing and apprehensive expectation and had a stronger influence on changes between suicidal ideation and concentration. CfD had a stronger direct influence on thoughts of being a failure and on the associated change between being an easily annoyed and apprehensive of expectation. There were inconsistencies when modelling change using the first and second appointments as the baseline. Residual score models produced more conservative findings than models using difference scores.

CONCLUSIONS

CfD and CBT for depression have differential effects on symptoms demonstrating specific mechanisms of change.

CLINICAL IMPLICATIONS

CBT was uniquely associated with changes in symptoms associated with anxiety and may be better suited to those with anxiety symptoms comorbid to their depression. When assessing change, the baseline should be the first therapy session, not the pretreatment assessment. Residual change scores should be preferred over difference score methods.

Prevalence of anxiety disorders and association to socioeconomic position. Results from the Lolland Falster Health Study

PURPOSE

The purpose of this study is to describe the prevalence of anxiety disorders in a general population and the association to socioeconomic position (SEP), which has not been described in a Danish context before.

MATERIAL AND METHODS

We present data on anxiety symptoms from respondents in the rural-provincial Lolland-Falster population Health Study (LOFUS). Analyses of the questionnaire responses to the Anxiety Symptom Scale were done by descriptive statistics and logistic regression analyses adjusted for sex and age.

RESULTS

14,834 LOFUS respondents who completed the Anxiety Symptom Scale were included; According to the original algorithm 371 (2.5%) had an anxiety disorder. The adjusted odds ratios (aOR) for anxiety disorder were strongly associated to SEP. We found aOR for anxiety to be: 3.8 (confidence interval (CI 95%) 2.54 - 5.92) for respondents with no postsecondary education compared to those with 3+ years of postsecondary education; 11.9 (CI 8.89 - 16.01) for respondents temporarily out of a job compared to those working; 9.4 (CI 6.06 - 14.51) for those experiencing constant financial strain compared to those not experiencing financial strain. Relaxing the criteria for anxiety to item 10 > 1, the prevalence raised to 3.9%. The association was unchanged related to education; however, the aOR dropped to 9 and 8 respectively, for being temporally out of job, or in financial strain every month- when doing same comparisons.

CONCLUSIONS

The 14-day prevalence of anxiety disorder seems low but strongly associated to SEP especially for individuals temporarily out of a job or experiencing financial strain.
