Cognitive behaviour therapy for depression in primary care: systematic review and meta-analysis

Are cognitive behavioural therapy, cognitive therapy, and behavioural activation for depression effective in primary care? A systematic review and meta-analysis

Cognitive behavioural therapy (CBT) is a recommended first-line treatment for depression. Evidence mainly derives from studies in secondary care, though most treatment occurs in primary care. This review examined efficacy of CBT, cognitive therapy (CT), or behavioural activation (BA) for depression within primary care. Databases were searched for trials up to 23rd July 2024. Risk of bias was assessed using the Cochrane risk-of-bias tool, version 2.0.44 studies were included. CBT, CT, and BA significantly reduced depression symptoms compared to inactive controls (k = 40, g = 0.44, p < .001), but not active comparators (other therapies, medication or exercise) (k = 9, g = -0.06, p = .24). Heterogeneity was significant in studies comparing CBT, CT, or BA to inactive controls, but not in studies using active comparators. Most studies were rated at high risk of bias (36 studies, 81.8 %), predominantly due to use of patient-rated outcome measures in non-blinded studies, lack of ITT analyses, and lack of pre-registering protocols, all of which may result in inflated effect sizes. Although CBT, CT, or BA appears effective for depression in primary care against usual care or waiting list controls, when compared to active comparators no significant difference is seen, likely a result of variability in the quality of the included studies. Large studies of improved quality (including use of blinded observer-rated outcome measures and ITT analyses) may be required to justify guideline recommendations for CBT over other interventions for depression specifically in primary care.

Antidepressant Use in New-Onset Depression After Total Joint Arthroplasty Is Not Associated With Reduced Arthroplasty-Related Complications

Background and objective Some patients without pre-existing depression develop new-onset depression (NOD) following total joint arthroplasty (TJA), potentially impacting recovery and quality of life. New-onset depression has been associated with increased TJA complications (i.e., periprosthetic fracture, prosthetic joint infection, and revision), but the role of antidepressants in this population remains unexplored. This paper assessed the prevalence of antidepressant use in TJA patients with NOD and its association with postoperative complications. Methods We conducted a retrospective cohort study using a national database (2010-2022). Primary TJA patients aged ≥18 years with osteoarthritis and NOD within six months were included, while those with preoperative depression, antidepressant use, or < one-year follow-up were excluded. Study groups comprised those on antidepressants; controls consisted of those not on antidepressants. Logistic regressions adjusting for age, sex, and comorbidities assessed the odds of one-year postoperative complications. Results Among TJA patients with NOD, 25.3% (n=1,735) of total hip arthroplasty (THA) and 27.6% (n=4,365) of total knee arthroplasty (TKA) patients used antidepressants. Total hip arthroplasty patients on antidepressants had 1.70 times higher odds of periprosthetic fracture (95% CI: 1.22, 2.36) but showed no significant differences in prosthetic joint infection or revision. No significant differences were found in the TKA group. Conclusions Antidepressant use in NOD was not associated with reduced arthroplasty-related complications; however, treating depressive symptoms may still aid recovery. Further research, incorporating patient-level data on depression severity, therapy, and social support, antidepressant subclassification, and medication dosing and duration, is needed to identify which patients benefit from antidepressants and optimize postoperative mental health management.

Design and methods of the research unit 5187 PREACT (towards precision psychotherapy for non-respondent patients: from signatures to predictions to clinical utility) - a study protocol for a multicentre observational study in outpatient clinics

INTRODUCTION

Cognitive-behavioural therapy (CBT) works-but not equally well for all patients. Less than 50% of patients with internalising disorders achieve clinically meaningful improvement, with negative consequences for patients and healthcare systems. The research unit (RU) 5187 seeks to improve this situation by an in-depth investigation of the phenomenon of treatment non-response (TNR) to CBT. We aim to identify bio-behavioural signatures associated with TNR, develop predictive models applicable to individual patients and enhance the utility of predictive analytics by collecting a naturalistic cohort with high ecological validity for the outpatient sector.

METHODS AND ANALYSIS

The RU is composed of nine subprojects (SPs), spanning from clinical, machine learning and neuroimaging science and service projects to particular research questions on psychological, electrophysiological/autonomic, digital and neural signatures of TNR. The clinical study SP 1 comprises a four-centre, prospective-longitudinal observational trial where we recruit a cohort of 585 patients with a wide range of internalising disorders (specific phobia, social anxiety disorder, panic disorder, agoraphobia, generalised anxiety disorder, obsessive-compulsive disorder, post-traumatic stress disorder, and unipolar depressive disorders) using minimal exclusion criteria. Our experimental focus lies on emotion (dys)-regulation as a putative key mechanism of CBT and TNR. We use state-of-the-art machine learning methods to achieve single-patient predictions, incorporating pretrained convolutional neural networks for high-dimensional neuroimaging data and multiple kernel learning to integrate information from various modalities. The RU aims to advance precision psychotherapy by identifying emotion regulation-based biobehavioural markers of TNR, setting up a multilevel assessment for optimal predictors and using an ecologically valid sample to apply findings in diverse clinical settings, thereby addressing the needs of vulnerable patients.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Institutional Ethics Committee of the Department of Psychology at Humboldt-Universität zu Berlin (approval no. 2021-01) and the Ethics Committee of Charité-Universitätsmedizin Berlin (approval no. EA1/186/22).Results will be disseminated through peer-reviewed journals and presentations at national and international conferences. Deidentified data and analysis scripts will be made available to researchers within the RU via a secure server, in line with ethical guidelines and participant consent. In compliance with European and German data protection regulations, patient data will not be publicly available through open science frameworks but may be shared with external researchers on reasonable request and under appropriate data protection agreements.

Trajectory of peripheral inflammation during index ECT in association with clinical outcomes in treatment-resistant depression

Background

Electroconvulsive therapy (ECT) is a highly efficacious intervention for severe and intractable depression. Evidence suggests ECT provokes an initial acute inflammatory response that subsequently decreases with repeated administration. However, relationships between inflammatory changes and clinical effects are unclear. Improved understanding of these processes may provide critical insight into effective intervention for treatment-resistant depression (TRD).

Methods

Plasma inflammatory markers were assessed at pre-treatment (T1), after the second ECT session (T2), and after ECT index series completion (post-treatment/T3) in TRD (n = 40). Changes were examined over time and in association with post-treatment Responder/Non-responder status (≥50% reduction in global depression severity) and percent change in affective, cognitive and neurovegetative depressive symptom domains.

Results

C-reactive protein (CRP) and interleukin-6 (IL-6) increased from pre-treatment to T2, and decreased from T2 to post-treatment. Neither early (%T2-T1) nor total (%T1-T3) change in inflammation predicted clinical outcomes, however, the interaction between early/acute inflammatory response and post-treatment inflammation (relative to baseline) was associated with clinical outcomes. Larger initial increases in IL-6 predicted greater reductions in both affective and cognitive symptoms in subjects with higher post-treatment IL-6; those with lower post-treatment IL-6 trended toward the opposite. The same was found between changes in CRP and neurovegetative symptoms.

Conclusions

Though preliminary, these results demonstrate how processes involved in the acute inflammatory response to ECT may differentially influence clinical outcomes depending on overall trajectory of inflammation following ECT. Findings also highlight the importance of examining symptom-specific changes in depression when studying treatment mechanisms, rather than relying solely on global measures of severity.

Shared Paths to Well-Being: The Impact of Group Therapy

This study explored the impact of an art of living intervention within group psychotherapy for depression, focusing on constructs like life satisfaction, self-efficacy, and depression. Mental illness prevalence often exceeds available treatment options, particularly in Germany, where group psychotherapy is a viable alternative. While less researched, group therapy effectively improves well-being, especially through interpersonal exchange. Meta-analyses confirm cognitive behavioral group therapy's effectiveness against depression, encouraging further investigation. This study employed a two-factor experimental design with randomized group allocation. The control group (CG) participated in weekly 50 min sessions for four weeks, while the experimental group (EG) received identical therapy plus reflective life-stimulating questions. Measures of depression, art of living, life satisfaction, and self-efficacy were taken before, after, and three months post-intervention. Among 107 participants, 52 were in the EG and 55 were in the CG. The results showed a significant 24% reduction in depression scores in the experimental group, a significant 16% increase in the art of living and a significant 19% increase in life satisfaction, while the CG showed no significant changes. Self-efficacy did not significantly improve in the EG. Follow-up data indicated sustained improvements in depression and art of living for the EG. The limitations of this study include a limited scope, practical constraints, randomization challenges and confounding variables, which are typical for experimental studies. These findings highlight the intervention's potential, suggesting future research focusing on long-term effects, personality factors and disorder-specific applications.

Psychological stressors involved in the pathogenesis of premature ovarian insufficiency and potential intervention measures

Premature ovarian insufficiency (POI) is a common gynecological endocrine disease, which seriously affects women's physical and mental health and fertility, and its incidence is increasing year by year. With the development of social economy and technology, psychological stressors such as anxiety and depression caused by social, life and environmental factors may be one of the risk factors for POI. We used PubMed to search peer-reviewed original English manuscripts published over the last 10 years to identify established and experimental studies on the relationship between various types of stress and decreased ovarian function. Oxidative stress, follicular atresia, and excessive activation of oocytes, caused by Stress-associated factors may be the main causes of ovarian function damage. This article reviews the relationship between psychological stressors and hypoovarian function and the possible early intervention measures in order to provide new ideas for future clinical treatment and intervention.

Cost-Effectiveness of Computer-Assisted Cognitive Behavioral Therapy for Depression Among Adults in Primary Care

Importance

Approximately 1 in 5 adults are diagnosed with depression in their lifetime. However, less than half receive help from a health professional, with the treatment gap being worse for individuals with socioeconomic disadvantage. Computer-assisted cognitive behavioral therapy (CCBT) is an effective and convenient strategy to treat depression; however, its cost-effectiveness in a sociodemographically diverse population remains unknown.

Objective

To evaluate the cost-effectiveness of clinician-supported CCBT compared with treatment as usual (TAU) in a primary care population with a substantial number of patients with low income, limited computer or internet access, and lack of college education.

Design, Setting, and Participants

This economic evaluation was a randomized clinical trial-based cost-effectiveness analysis. The trial was conducted at the Departments of Family and Geriatric Medicine and Internal Medicine at the University of Louisville. Enrollment occurred from June 24, 2016, to May 13, 2019. Participants had mild to moderate depression and were followed up for 6 months after treatment completion. The last follow-up assessment was conducted on January 30, 2020. Statistical analysis was performed from August 2023 to August 2024.

Exposure

CCBT intervention was provided for 12 weeks and included 9 modules ranging from behavioral activation and cognitive restructuring to relapse prevention strategies, supported by telephonic sessions with a clinician, in addition to TAU, which included standard clinical management in primary care.

Main Outcomes and Measures

The primary health outcome was quality-adjusted life years (QALYs), estimated using the Short-Form 12 questionnaire (SF-12). The secondary outcome was treatment response, defined as at least 50% improvement in the Patient Health Questionnaire. The intervention cost included sessions with mental health clinicians and the cost of the CCBT software, plus the cost of loaner computer and internet data plan for low-resource households. An incremental cost-effectiveness ratio (ICER) was computed, while adjusting for baseline scores, age, and sex. The cost-effectiveness acceptability curve presented the probability of CCBT being cost-effective for a range of willingness-to-pay values.

Results

Among the 175 primary care patients included in this study, 148 (84.5%) were female; 48 (27.4%) were African American, 2 (1.2%) were American Indian or Alaska Native, 4 (2.5%) were Hispanic, 106 (60.5%) were White, and 15 (8.6%) were multiracial; and the mean (SD) age was 47.03 (13.15) years. CCBT was associated with better quality of life and higher chance of treatment response at the posttreatment and 6-month time points, compared with the TAU group. The ICER for CCBT was $37 295 (95% CI, $22 724-$66 546) per QALY, with a probability of 89.4% of being cost-effective at a willingness-to-pay threshold of $50 000/QALY. The ICER per case of treatment response was $3623 (95% CI, $2617-$5377).

Conclusions and Relevance

In this trial-based economic evaluation, CCBT was found to be cost-effective, compared with TAU, in primary care patients with depression. As this study included individuals with low income and with limited internet access who are underrepresented in cost-effectiveness studies, it has important policy implications for addressing unmet needs in sociodemographically diverse populations.

Toward a Comprehensive Model of Medical-Dental-Behavioral Integration

INTRODUCTION

Existing models of medical-dental integration, as well as those from behavioral health care integrated with primary medical treatment, provide a basis for a truly synthesized and expanded model incorporating medical, dental, and behavioral components. Such a comprehensive model allows for collaborative health care serving patients seamlessly without disciplinary silos, promoting optimal whole-person health. This innovative approach is consistent with recent developments in the behavioral and social oral health sciences that include an imperative for their full inclusion in dental health care, research, and education.

METHODS

Existing models of medical-dental integration are described, along with current models from integrated primary medical and behavioral health care. Using these existing approaches as a basis, a new multilevel model is proposed to include social and cultural determinants of health.

RESULTS

Contemporary approaches to providing health care across disciplines include referral to a geographically separate entity, co-location of services, and integrated, side-by-side care. Integration of electronic health records and interoperability are necessary (but not sufficient) factors that affect transdisciplinary health care. Effective communication among health care providers and the need for interprofessional education, comprehensive training, and ongoing cross-disciplinary consultation also are noted as crucial factors in truly collaborative care. Evidence for existing models varies greatly depending on the target population and type of services provided.

CONCLUSIONS

A fully integrated, transdisciplinary model of health care is possible, theoretically and practically. Combining aspects of extant integrated models and extending them provides opportunity for a greater focus on systemic factors and more emphasis on prevention. Consistent with this new model, medical and dental home concepts can be expanded to that of a person-centered health care home that includes interprofessional practice. This transdisciplinary approach contributes to greater health equity given the multilevel approach. Multidirectional integration of diverse disciplines representing the various realms of medicine, dentistry, and behavioral health care is essential for optimal health of all.

KNOWLEDGE TRANSFER STATEMENT

This article can be used by clinicians, scientists, administrators, and policy makers in developing and implementing integrated systems of care that provide for patients' medical, dental, and behavioral health needs.

Model of integrated mental health video consultations for people with depression or anxiety in primary care (PROVIDE-C): assessor masked, multicentre, randomised controlled trial

OBJECTIVE

To evaluate whether an integrated mental health video consultation approach (PROVIDE model) can improve symptoms compared with usual care in adults with depression and anxiety disorders attending primary care.

DESIGN

Assessor masked, multicentre, randomised controlled trial (PROVIDE-C).

SETTING

In 29 primary care practices in Germany, working remotely online from one trial hub.

PARTICIPANTS

376 adults (18-81 years) who presented to their general practitioner (GP) with depression or anxiety, or both.

INTERVENTION

Participants were randomised (1:1) to receive the PROVIDE model (n=187) or usual care (n=189). Usual care was provided by GPs through interventions such as brief counselling and psychotropic medication prescriptions and may or may not have included referrals to mental health specialists. The PROVIDE model comprised transdiagnostic treatment provided through five real-time video sessions between the patient at the primary care practice and a mental health specialist at an offsite location.

MAIN OUTCOME MEASURES

The primary outcome was the absolute change in the mean severity of depressive and anxiety symptoms measured using the patient health questionnaire anxiety and depression scale (PHQ-ADS) at six months, in the intention-to-treat population. Secondary outcomes, measured at six and 12 months, included PHQ-ADS subscores, psychological distress related to somatic symptoms, recovery, health related quality of life, quality and patient centredness of chronic illness care, and adverse events.

RESULTS

Between 24 March 2020 and 23 November 2021, 376 patients were randomised into treatment groups. Mean age was 45 years (standard deviation (SD) 14), 63% of the participants were female, and mean PHQ-ADS-score was 26 points (SD 7.6). Compared with usual care, the PROVIDE intervention led to improvements in severity of depressive and anxiety symptom (adjusted mean change difference in the PHQ-ADS score -2.4 points (95% confidence interval -4.5 to -0.4), P=0.02) at six months. The effects were sustained at 12 months (-2.9 (-5.0 to -0.7), P<0.01). No serious adverse events were reported in either group.

CONCLUSIONS

Through relatively low intensity treatment, the PROVIDE model led to a decrease in depressive and anxiety symptoms with small effects in the short and long term. Depression and anxiety disorders are prevalent and therefore the small effect might cumulatively impact on population health in this population.

Investigation of Ukrainian refugees' eating behavior, food intake, and psychological distress: Study protocol and baseline data

Since the start of the war in Ukraine, almost 8 million people left the country; more than 1 million of them relocated to Germany. It is to be expected that the war puts considerable strain on refugees, which will impact the public health system in host countries. This paper presents baseline data and protocol of longitudinal online experimental study of 619 Ukrainian refugees in Germany started in autumn 2022, focusing on participants' self-reports of appetite, food intake, and levels of stress, anxiety, and depressive symptoms to examine their associations. Results indicate that levels of stress, anxiety, and depressive symptoms in refugees significantly exceed the indicators of relevant parameters as reported by independent large-scale surveys conducted in Ukraine before the war as well as strong correlations between these deviations (.59 ≤ r ≤ .69, p = .005). Changes in appetite were related to more severe psycho-emotional deviations (.15 ≤ r ≤ .19, p = .003) and somewhat unhealthier food intake (r = -.08, p < .001). The study underlines the need of psychological care for refugees to improve their mental health and counteract potential negative consequences for physical health via changes in food intake, for which suitable interventions need to be developed.

Nurse-delivered sleep restriction therapy to improve insomnia disorder in primary care: the HABIT RCT

Background

Insomnia is a prevalent and distressing sleep disorder. Multicomponent cognitive-behavioural therapy is the recommended first-line treatment, but access remains extremely limited, particularly in primary care where insomnia is managed. One principal component of cognitive-behavioural therapy is a behavioural treatment called sleep restriction therapy, which could potentially be delivered as a brief single-component intervention by generalists in primary care.

Objectives

The primary objective of the Health-professional Administered Brief Insomnia Therapy trial was to establish whether nurse-delivered sleep restriction therapy in primary care improves insomnia relative to sleep hygiene. Secondary objectives were to establish whether nurse-delivered sleep restriction therapy was cost-effective, and to undertake a process evaluation to understand intervention delivery, fidelity and acceptability.

Design

Pragmatic, multicentre, individually randomised, parallel-group, superiority trial with embedded process evaluation.

Setting

National Health Service general practice in three regions of England.

Participants

Adults aged ≥ 18 years with insomnia disorder were randomised using a validated web-based randomisation programme.

Interventions

Participants in the intervention group were offered a brief four-session nurse-delivered behavioural treatment involving two in-person sessions and two by phone. Participants were supported to follow a prescribed sleep schedule with the aim of restricting and standardising time in bed. Participants were also provided with a sleep hygiene leaflet. The control group received the same sleep hygiene leaflet by e-mail or post. There was no restriction on usual care.

Main outcome measures

Outcomes were assessed at 3, 6 and 12 months. Participants were included in the primary analysis if they contributed at least one post-randomisation outcome. The primary end point was self-reported insomnia severity with the Insomnia Severity Index at 6 months. Secondary outcomes were health-related and sleep-related quality of life, depressive symptoms, work productivity and activity impairment, self-reported and actigraphy-defined sleep, and hypnotic medication use. Cost-effectiveness was evaluated using the incremental cost per quality-adjusted life-year. For the process evaluation, semistructured interviews were carried out with participants, nurses and practice managers or general practitioners. Due to the nature of the intervention, both participants and nurses were aware of group allocation.

Results

We recruited 642 participants (n = 321 for sleep restriction therapy; n = 321 for sleep hygiene) between 29 August 2018 and 23 March 2020. Five hundred and eighty participants (90.3%) provided data at a minimum of one follow-up time point; 257 (80.1%) participants in the sleep restriction therapy arm and 291 (90.7%) participants in the sleep hygiene arm provided primary outcome data at 6 months. The estimated adjusted mean difference on the Insomnia Severity Index was -3.05 (95% confidence interval -3.83 to -2.28; p < 0.001, Cohen's d = -0.74), indicating that participants in the sleep restriction therapy arm [mean (standard deviation) Insomnia Severity Index = 10.9 (5.5)] reported lower insomnia severity compared to sleep hygiene [mean (standard deviation) Insomnia Severity Index = 13.9 (5.2)]. Large treatment effects were also found at 3 (d = -0.95) and 12 months (d = -0.72). Superiority of sleep restriction therapy over sleep hygiene was evident at 3, 6 and 12 months for self-reported sleep, mental health-related quality of life, depressive symptoms, work productivity impairment and sleep-related quality of life. Eight participants in each group experienced serious adverse events but none were judged to be related to the intervention. The incremental cost per quality-adjusted life-year gained was £2075.71, giving a 95.3% probability that the intervention is cost-effective at a cost-effectiveness threshold of £20,000. The process evaluation found that sleep restriction therapy was acceptable to both nurses and patients, and delivered with high fidelity.

Limitations

While we recruited a clinical sample, 97% were of white ethnic background and 50% had a university degree, which may limit generalisability to the insomnia population in England.

Conclusions

Brief nurse-delivered sleep restriction therapy in primary care is clinically effective for insomnia disorder, safe, and likely to be cost-effective.

Future work

Future work should examine the place of sleep restriction therapy in the insomnia treatment pathway, assess generalisability across diverse primary care patients with insomnia, and consider additional methods to enhance patient engagement with treatment.

Change in negative mental filter is associated with depression reduction in metacognitive training for depression in older adults (MCT-Silver)

Identifying components of modularized psychological interventions that contribute to symptom reduction is essential to improving depression treatment. In a secondary analysis of a randomized controlled trial (RCT), session-specific effects of Metacognitive Training-Silver, a group intervention for older adults with depression, were investigated. Thirty-eight older adults with major depressive disorder or dysthymia participated in up to eight sessions of MCT-Silver. A clinical assessment of depressive symptoms (Hamilton Depression Rating Scale) as well as additional interviews and questionnaires administered as part of the RCT were completed at pre- and post-intervention. Depressive symptoms, negative (meta)cognitive beliefs, emotion regulation strategies and attitudes toward aging were assessed pre- and post-session. The rate of change in each variable per module, elevation following the module in which the variable was addressed, and the rate of change post module were examined via linear mixed models. Clinician-rated depressive symptoms were significantly reduced from pre- to post-intervention (Cohens d = 1.31). Self-reported depression and negative mental filter measured within sessions improved significantly over treatment, whereas black-and-white thinking improved after module #3 (Should Statements, All or Nothing Thinking and Acceptance). Module-specific within-session effects were found for overgeneralization (module #1: Mental Filter) and rumination (module #6: Rumination and Social Withdrawal). Improvement in mental filter in module #1 was significantly associated with depression reduction. This study provides initial evidence that MCT-Silver partially meets its aims of reducing depression and specific cognitive variables within and across sessions. Improvement of the instrument used to measure change may improve detection of module-specific effects.Trial registration: NCT03691402.

Brief scales for the measurement of target variables and processes of change in cognitive behaviour therapy for major depression, panic disorder and social anxiety disorder

BACKGROUND

The measurement of process variables derived from cognitive behavioural theory can aid treatment development and support the clinician in following treatment progress. Self-report process measures are ideally brief, which reduces the burden on patients and facilitates the implementation of repeated measurements.

AIMS

To develop 13 brief versions (3-6 items) of existing cognitive behavioural process scales for three common mental disorders: major depression, panic disorder, and social anxiety disorder.

METHOD

Using data from a real-world teaching clinic offering internet-delivered cognitive behavior therapy (n=370), we drafted brief process scales and then validated these scales in later cohorts (n=293).

RESULTS

In the validation data, change in the brief process scales significantly mediated change in the corresponding domain outcomes, with standardized coefficient point estimates in the range of -0.53 to -0.21. Correlations with the original process scales were substantial (r=.83-.96), internal consistency was mostly adequate (α=0.65-0.86), and change scores were moderate to large (|d|=0.51-1.18). For depression, the brief Behavioral Activation for Depression Scale-Activation subscale was especially promising. For panic disorder, the brief Agoraphobic Cognitions Questionnaire-Physical Consequences subscale was especially promising. For social anxiety disorder, the Social Cognitions Questionnaire, the Social Probability and Cost Questionnaire, and the Social Behavior Questionnaire-Avoidance and Impression Management subscales were all promising.

CONCLUSIONS

Several brief process scales showed promise as measures of treatment processes in cognitive behaviour therapy. There is a need for replication and further evaluation using experimental designs, in other clinical settings, and preferably in larger samples.

Neuroregulatory Effects of Microcone Patch Stimulation on the Auricular Branch of the Vagus Nerve and the Prefrontal Cortex: A Feasibility Study

Background: The primary purpose of this study was to preliminarily examine the effects of autonomic nervous system activity on the dorsolateral prefrontal cortex. Recent studies have examined approaches to modulating autonomic activity using invasive and non-invasive methods, but the effects of changes in autonomic activity during cognitive tasks on the dorsolateral prefrontal cortex have not been fully investigated. The purpose of this preliminary investigation was to examine changes in autonomic activity and blood oxygen saturation in the dorsolateral prefrontal cortex during reading tasks induced by vagus nerve stimulation using a microcone patch. Methods: A cohort of 40 typically developing adults was enrolled in this study. We carefully examined changes in autonomic nervous system activity and blood oxygen saturation in the dorsolateral prefrontal cortex during a reading task in two conditions: with and without microcone patch stimulation. Results: Significant changes in brain activation in the dorsolateral prefrontal cortext due to microcone patch stimulation were confirmed. In addition, hierarchical multiple regression analysis revealed specific changes in reading task-related blood oxygen saturation in the dorsolateral prefrontal region during microcone patch stimulation. Conclusions: It should be recognized that this study is a preliminary investigation and does not have immediate clinical applications. However, our results suggest that changes in autonomic nervous system activity induced by external vagal stimulation may affect activity in specific reading-related regions of the dorsolateral prefrontal cortex. Further research and evaluation are needed to fully understand the implications and potential applications of these findings.

Internet-delivered transdiagnostic psychological treatments for individuals with depression, anxiety or both: a systematic review with meta-analysis of randomised controlled trials

OBJECTIVE

Depression and anxiety are major public health problems. This study evaluated the effects of internet-delivered transdiagnostic psychological treatments for individuals with depression, anxiety, or both.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

Medline (Ovid), Cochrane Library (Wiley), the Web of Science Core Collection (Clarivate), and PsycInfo (EBSCO) were searched on 24 May 2021, with an update on 6 February 2023.

ELIGIBILITY CRITERIA

Randomised controlled trials of internet-delivered transdiagnostic psychological treatments, open to both participants with primary depression and participants with primary anxiety. This review concerned all treatment frameworks, both guided and unguided formats and all age groups.

DATA EXTRACTION AND SYNTHESIS

In random-effects meta-analysis, we estimated pooled effects on depression symptoms and anxiety in terms of Hedges' g with 95% CIs. Absolute and relative heterogeneity was quantified as the τ2 and I 2.

RESULTS

We included 57 trials with 21 795 participants. Nine trials (16%) recruited exclusively from routine care, and three (5%) delivered treatment via video. For adults, large within-group reductions were seen in depression (g=0.90; 95% CI 0.81 to 0.99) and anxiety (g=0.87; 95% CI 0.78 to 0.96). Compared with rudimentary passive controls, the added effects were moderate (depression: g=0.52; 95% CI 0.42 to 0.63; anxiety: g=0.45; 95% CI 0.34 to 0.56) and larger in trials that required all participants to meet full diagnostic criteria for depression or an anxiety disorder. Compared with attention/engagement controls, the added effects were small (depression: g=0.30; 95% CI 0.07 to 0.53; anxiety: g=0.21; 95% CI 0.01 to 0.42). Heterogeneity was substantial, and the certainty of the evidence was very low. Two trials concerned adolescents and reported mixed results. One trial concerned older adults and reported promising results.

CONCLUSION

Internet-delivered transdiagnostic treatments for depression and anxiety show small-to-moderate added effects, varying by control condition. Research is needed regarding routine care, the video format, children and adolescents and older adults.

Value-based pricing of cognitive behavioral therapy for depression in primary care: an economic evaluation

OBJECTIVES

Value-based pricing (VBP) determines product prices based on their perceived benefits. In healthcare, VBP prices medical technologies considering health outcomes and other relevant factors. This study applies VBP using economic evaluation to provider-patient communication, taking cognitive behavioral therapy (CBT) for adult primary care patients with depressive disorders as a case study.

METHODS

A 12-week decision-tree model was developed from the German social health insurance system's perspective, comparing CBT against the standard of care. The influence of an extended time horizon on VBP was assessed using a theoretical model and long-term data spanning 46 months.

RESULTS

Using a willingness-to-pay threshold of €88,000 per quality-adjusted life year gained, the base-case 50-minute compensation rate for CBT was €45. Assuming long-term effects of CBT significantly affected the value-based compensation, increasing it to €226.

CONCLUSIONS

This study showcases the potential of applying VBP to CBT. However, significant price variability is highlighted, contingent upon assumptions regarding CBT's long-term impacts.

Psychological treatment of adult depression in primary care compared with outpatient mental health care: A meta-analysis

BACKGROUND

It is not yet known whether psychological treatments of depression in primary care have comparable effects to treatments in specialized mental health care. We conducted a meta-analysis comparing randomized controlled trials in primary and specialized care.

METHODS

We selected studies from an existing database of randomized trials of psychological treatments of depression in adults, which was built through searches in PubMed, PsychINFO, Embase and the Cochrane Library. Random effects meta-analyses were conducted to examine the effects of therapies and mixed effects subgroup analyses were used to compare the effects in primary and specialized care.

RESULTS

We included 52 trials (7984 patients) in primary care and compared them with 50 trials (3685 patients) in specialized care. The main effect of therapies in primary care was g = 0.43 (95 % CI: 0.32; 0.53; PI: -0.18; 1.03). The overall effects were significantly smaller than those in specialized care (p = 0.006), but this was no longer significant after adjustment for differences between the two settings. The proportion of patients responding to treatment was comparable in primary (0.38; 95 % CI: 0.33; 0.43) and specialized care (0.34; 95 % CI: 0.28; 0.41; p = 0.41), but higher in control conditions in primary care (0.25; 95 % CI: 0.22; 0.28) compared to specialized care (0.16; 95 % CI: 0.12; 0.20; p < 0.001).

DISCUSSION

Psychological treatments are effective in primary care, but somewhat less than in specialized care. Response rates in control conditions in primary care are higher than in specialized care, which may point at a transient nature of depression in primary care.

Clinical and cost-effectiveness of nurse-delivered sleep restriction therapy for insomnia in primary care (HABIT): a pragmatic, superiority, open-label, randomised controlled trial

BACKGROUND

Insomnia is prevalent and distressing but access to the first-line treatment, cognitive behavioural therapy (CBT), is extremely limited. We aimed to assess the clinical and cost-effectiveness of sleep restriction therapy, a key component of CBT, which has the potential to be widely implemented.

METHODS

We did a pragmatic, superiority, open-label, randomised controlled trial of sleep restriction therapy versus sleep hygiene. Adults with insomnia disorder were recruited from 35 general practices across England and randomly assigned (1:1) using a web-based randomisation programme to either four sessions of nurse-delivered sleep restriction therapy plus a sleep hygiene booklet or a sleep hygiene booklet only. There was no restriction on usual care for either group. Outcomes were assessed at 3 months, 6 months, and 12 months. The primary endpoint was self-reported insomnia severity at 6 months measured with the insomnia severity index (ISI). The primary analysis included participants according to their allocated group and who contributed at least one outcome measurement. Cost-effectiveness was evaluated from the UK National Health Service and personal social services perspective and expressed in terms of incremental cost per quality-adjusted life year (QALY) gained. The trial was prospectively registered (ISRCTN42499563).

FINDINGS

Between Aug 29, 2018, and March 23, 2020 we randomly assigned 642 participants to sleep restriction therapy (n=321) or sleep hygiene (n=321). Mean age was 55·4 years (range 19-88), with 489 (76·2%) participants being female and 153 (23·8%) being male. 580 (90·3%) participants provided data for at least one outcome measurement. At 6 months, mean ISI score was 10·9 (SD 5·5) for sleep restriction therapy and 13·9 (5·2) for sleep hygiene (adjusted mean difference -3·05, 95% CI -3·83 to -2·28; p<0·0001; Cohen's d -0·74), indicating that participants in the sleep restriction therapy group reported lower insomnia severity than the sleep hygiene group. The incremental cost per QALY gained was £2076, giving a 95·3% probability that treatment was cost-effective at a cost-effectiveness threshold of £20 000. Eight participants in each group had serious adverse events, none of which were judged to be related to intervention.

INTERPRETATION

Brief nurse-delivered sleep restriction therapy in primary care reduces insomnia symptoms, is likely to be cost-effective, and has the potential to be widely implemented as a first-line treatment for insomnia disorder.

Anatomy of a Woebot® (WB001): agent guided CBT for women with postpartum depression

INTRODUCTION

Postpartum depression (PPD) is common, persistent, and stigmatized. There are insufficient trained professionals to deliver appropriate screening, diagnosis, and treatment.

AREAS COVERED

WB001 is a Software as a Medical Device (SaMD) based Agent-Guided Cognitive-Behavioral Therapy (AGCBT) program for the treatment of PPD, for which Breakthrough Device Designation was recently granted by the US Food and Drug Administration. WB001 combines therapeutic alliance, human-centered design, machine learning techniques, and established principles from CBT and interpersonal therapy (IPT). We introduce AGCBT as a new model of service delivery, whilst describing Woebot, the agent technology that enables guidance through the replication of some elements of human relationships. The profile describes the device's design principles, enabling technology, risk handling, and efficacy data in PPD.

EXPERT OPINION

WB001 is a dynamic and personalized tool with which patients may establish a therapeutic bond. Woebot is designed to augment (rather than replace) human healthcare providers, unlocking the therapeutic potency associated with guidance, whilst retaining the scalability and agency that characterizes self-help approaches. WB001 has the potential to improve both the quality and the scalability of care through providing support to patients on waiting lists, in between clinical encounters, and enabling automation of measurement-based-care.

Feasibility and Preliminary Efficacy of Digital Interventions for Depressive Symptoms in Working Adults: Multiarm Randomized Controlled Trial

BACKGROUND

Depressive symptoms are highly prevalent and have broad-ranging negative implications. Digital interventions are increasingly available in the workplace context, but supporting evidence is limited.

OBJECTIVE

This study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of 3 digital interventions for depressive symptoms in a sample of UK-based working adults experiencing mild to moderate symptoms.

METHODS

This was a parallel, multiarm, pilot randomized controlled trial. Participants were allocated to 1 of 3 digital interventions or a waitlist control group and had 3 weeks to complete 6 to 8 short self-guided sessions. The 3 interventions are available on the Unmind mental health app for working adults and draw on behavioral activation, cognitive behavioral therapy, and acceptance and commitment therapy. Web-based assessments were conducted at baseline, postintervention (week 3), and at 1-month follow-up (week 7). Participants were recruited via Prolific, a web-based recruitment platform, and the study was conducted entirely on the web. Feasibility and acceptability were assessed using objective engagement data and self-reported feedback. Efficacy outcomes were assessed using validated self-report measures of mental health and functioning and linear mixed models with intention-to-treat principles.

RESULTS

In total, 2003 individuals were screened for participation, of which 20.22% (405/2003) were randomized. A total of 92% (373/405) of the participants were retained in the study, 97.4% (295/303) initiated their allocated intervention, and 66.3% (201/303) completed all sessions. Moreover, 80.6% (229/284) of the participants rated the quality of their allocated intervention as excellent or good, and 79.6% (226/284) of the participants were satisfied or very satisfied with their intervention. All active groups showed improvements in well-being, functioning, and depressive and anxiety symptoms compared with the control group, which were maintained at 4 weeks. Hedges g effect sizes for depressive symptoms ranged from -0.53 (95% CI -0.25 to -0.81) to -0.74 (95% CI -0.45 to -1.03).

CONCLUSIONS

All interventions were feasible and acceptable, and the preliminary efficacy findings indicated that their use may improve depressive symptoms, well-being, and functioning. The predefined criteria for a definitive trial were met.

Characteristics of effective teletherapy for major depression: A systematic review

BACKGROUND

People would prefer to have psychotherapy as treatment over medication for major depression. There is evidence that psychotherapy does not require in-person delivery to be effective. Other modes of delivery, such as videoconferencing teletherapy, may make it a more accessible treatment.

METHOD

The aim of this review was to identify the characteristics of effective psychotherapy delivered by videoconference for adults in primary care with a primary diagnosis of depression. A quantitative systematic review was conducted and reported according to PRISMA guidelines.

RESULTS

There were 8 studies included in the review. The therapies studied were tele problem-solving therapy, behavioural activation and cognitive behavioural therapy. All studies had a medium to high risk of bias. Six were randomized controlled trials, one was a pragmatic retrospective cohort study and one was an open-label design. Four studies found similar outcomes to the in-person comparators, one study found tele problem-solving therapy was more effective than behavioural activation, and one study found cognitive behavioural therapy to be similar to usual care.

LIMITATIONS

The search identified only 8 studies. Due to the heterogeneity of outcome measures and comparators, a meta-analysis could not be conducted.

CONCLUSIONS

No definitive conclusions can be drawn about the effectiveness of teletherapy in primary care based on this review, however, there is emerging evidence to suggest it has similar outcomes to in-person therapy for people with a primary diagnosis of depression. There is no evidence regarding the superiority of one model of therapy over the others.

Internet-Based Cognitive Behavioural Therapy for Individuals With Depression and Chronic Health Conditions: A Systematic Review

Cognitive behavioural therapy (CBT) has heightened the need for internet-delivered intervention for depression with chronic diseases than a traditionally-based treatment procedure, and the need for CBT as an internet-delivered intervention has increased because it scales down the stigma of proceeding to a therapist, saves travel time from different geographical areas, and increases access to the service. This study aimed to evaluate the contemporary evidence for the effectiveness of internet-delivered cognitive behavioural therapy (CBT) as a treatment option for depression with chronic illness (CVD, diabetes, chronic pain, cancer, and chronic obstructive pulmonary disease (COPD)) among adult populations in high-income countries. A systematic search strategy was devised based on selecting search terms, inclusion and exclusion criteria, and refinement processes. Electronic searches were conducted using databases related to healthcare and containing peer-reviewed literature: the Cumulated Index to Nursing and Allied Health Literature (CINAHL), the Excerpta Medica Database (Embase), the Medical Literature Analysis and Retrieval System Online (Medline), and PsycINFO. Key search terms were applied to all databases and combined using Boolean operators to maximise the efficiency of the search. This review included randomised controlled trials (RCTs) evaluating the adult population aged ≥18 years published from 2006-2021. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was employed to guide the review process. The initial search yielded 134 studies across all databases, which were refined, leading to 18 studies in the final review data set. This review suggests that internet-based CBT is an effective strategy for reducing depressive symptoms in patients with comorbid depression and chronic diseases.

Medicaid reimbursement rates for primary care services and behavioral health outcomes

We study the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. Medicaid enrollees are at elevated risk for these, and other, chronic conditions and are likely to have unmet treatment needs. We apply two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016. We find that higher primary care reimbursement rates reduce mental illness and substance use disorders among non-elderly adult Medicaid enrollees, although we interpret findings for substance use disorders with some caution as they may be vulnerable to differential pre-trends. Overall, our findings suggest positive spillovers from a policy designed to target primary care services to behavioral health outcomes.

Treating depression with a smartphone-delivered self-help cognitive behavioral therapy for insomnia: a parallel-group randomized controlled trial

BACKGROUND

Despite its efficacy in treating comorbid insomnia and depression, cognitive behavioral therapy for insomnia (CBT-I) is limited in its accessibility and, in many countries, cultural compatibility. Smartphone-based treatment is a low-cost, convenient alternative modality. This study evaluated a self-help smartphone-based CBT-I in alleviating major depression and insomnia.

METHODS

A parallel-group randomized, waitlist-controlled trial was conducted with 320 adults with major depression and insomnia. Participants were randomized to receive either a 6-week CBT-I via a smartphone application, proACT-S, or waitlist condition. The primary outcomes included depression severity, insomnia severity, and sleep quality. The secondary outcomes included anxiety severity, subjective health, and acceptability of treatment. Assessments were administered at baseline, post-intervention (week 6) follow-up, and week 12 follow-up. The waitlist group received treatment after the week 6 follow-up.

RESULTS

Intention to treat analysis was conducted with multilevel modeling. In all but one model, the interaction between treatment condition and time at week 6 follow-up was significant. Compared with the waitlist group, the treatment group had lower levels of depression [Center for Epidemiologic Studies Depression Scale (CES-D): Cohen's d = 0.86, 95% CI (-10.11 to -5.37)], insomnia [Insomnia Severity Index (ISI): Cohen's d = 1.00, 95% CI (-5.93 to -3.53)], and anxiety [Hospital Anxiety and Depression Scale - Anxiety subscale (HADS-A): Cohen's d = 0.83, 95% CI (-3.75 to -1.96)]. They also had better sleep quality [Pittsburgh Sleep Quality Index (PSQI): Cohen's d = 0.91, 95% CI (-3.34 to -1.83)]. No differences across any measures were found at week 12, after the waitlist control group received the treatment.

CONCLUSION

proACT-S is an efficacious sleep-focused self-help treatment for major depression and insomnia.

Feasibility of a video-delivered mental health course for primary care patients: a single-group prospective cohort study

BACKGROUND

In many health care systems, primary care is tasked with offering psychological treatment for common mental disorders. Resources are often limited, which complicates widespread dissemination of traditional psychological treatments. Stepped care models where the less resource-intensive interventions are delivered first, can be employed, but often do not eliminate the need for a thorough diagnostic assessment, which can be time-consuming, has the potential to bottleneck patient intake, and can add to waiting times. Novel low-threshold formats are needed to improve access to mental health care in the primary care setting.

METHODS

This was a single-group prospective cohort study (N = 91). We assessed the feasibility of a video-delivered course as a first-line intervention for patients seeking help for mental health problems at a primary care center. The course had a transdiagnostic approach, suitable for both depression and anxiety disorders, and was based on cognitive behavioral techniques. Patients in need of psychosocial assessment, which usually entailed a four- to six-week wait, were referred by physicians or triage nurses. Study participants could start within a week, without the need for conventional diagnostic assessment, and were informed that they would be offered assessment after the course if needed. Key feasibility outcomes included participant satisfaction, attendance rates, the proportion of participants in need of additional clinical intervention after the course, and the rate of clinically significant improvement in anxiety and depression symptoms.

RESULTS

Participants scored a mean of 21.8 (SD = 4.0, 9-32, n = 86) on the Client Satisfaction Questionnaire-8; just below our target of 22. The mean attendance rate was 5.0/6 lectures (SD = 1.6, range: 0-6, n = 91). Forty-six percent (37/81) reported experiencing no need of further clinical intervention after the course. The rate of clinically significant improvement was 59% (27/46) for anxiety and 48% (22/46) for depression. No serious adverse event was reported.

CONCLUSIONS

Delivering a low-threshold online video-delivered mental health course in primary care appears to be feasible. Adjustments to further improve patient satisfaction are warranted, such as offering the choice of participating online or face-to-face.

Exploring service users experiences of remotely delivered CBT interventions in primary care during COVID-19: An interpretative phenomenological analysis

Primary Care Mental Health Services (PMHCS) aim to provide accessible and effective psychological interventions. However, there is a scarcity of qualitative research focused on patients' experiences. Service users' experience can inform development of accessible, high-quality mental health services. Nine semi-structured interviews were analysed from Primary Care Mental Health users in Northern Scotland using Interpretative Phenomenological Analysis (IPA). Four superordinate themes were generated: Orientating to treatment, Intervention features, Change enablers, and Impact. The results identified both facilitators and barriers associated with access and psychological change; and narratives around CBT acceptability, outcomes and remote delivery. The role of GPs emerged as a key determinant of access to PMHCS. The therapeutic relationship contributed to person-centred care provision, idiosyncratic change processes and self-empowerment. A personal commitment to engage with homework was described as a crucial change enabler. Findings are discussed in relation to existing literature, practical implications and suggestions for future research.

Physical exercise training as preceding treatment to cognitive behavioral therapy in mild to moderate major depressive disorder: A randomized controlled trial

BACKGROUND

Many patients with major depressive disorder (MDD) remain untreated or do not respond to cognitive behavioral therapy (CBT). Physical exercise shows antidepressive effects and may serve as an effective augmentation treatment. However, research on combining exercise with CBT is sparse in MDD and underlying mechanisms of exercise are not well understood to date.

METHODS

120 outpatients with MDD were randomized to either a high intensity exercise group (HEX), a low intensity exercise group (LEX), or a waiting list control group (WL). After 12 weeks of exercise training or waiting period, all patients received a manualized CBT.

RESULTS

Seventy-five patients with MDD completed both the exercise program/ waiting period and the CBT. While physical fitness improved in HEX after the exercise program, it did not change in LEX and WL. Depressive symptoms improved in all three groups from baseline to post-CBT and the group by time interaction was not significant. Regression analyses revealed that the amount of fitness improvement during exercise predicted the subsequent CBT response.

LIMITATIONS

The dropout rate was relatively high, preparatory CBT sessions during exercise / waiting period may have influenced depressive symptoms, and no patients with severe MDD were included.

CONCLUSIONS

High intense physical exercise did not lead to a general enhancement of CBT outcome, but higher increases in physical fitness seem to improve symptom change during CBT. Our results suggest that the implementation of more individually tailored exercise programs could be a promising approach for future research and clinical practice.

A cross-sectional study on fatigue, anxiety, and symptoms of depression and their relation with medical status in adult patients with Marfan syndrome. Psychological consequences in Marfan syndrome

Marfan syndrome (MFS) is a connective tissue disorder affecting the cardiovascular, ocular, and skeletal system, which may be accompanied by psychological features. This study aimed to determine the prevalence of fatigue, anxiety, and symptoms of depression in MFS patients, and to assess the degree to which sociodemographic and clinical variables are associated with fatigue and psychological aspects. The prevalence of fatigue, anxiety, and symptoms of depression were assessed in two cohorts of MFS patients and compared with healthy controls. The checklist individual strength (CIS), and hospital anxiety and depression scale (HADS) questionnaires were utilized. Medical status was assessed (family history of MFS, aortic root dilatation >40 mm, previous aortic surgery, aortic dissection, chronic pain, skeletal involvement, and scoliosis). Severe fatigue was experienced by 37% of the total MFS cohort (n = 155). MFS patients scored significantly higher on the CIS questionnaire, concerning severe fatigue, as compared with the general Dutch population (p < 0.0001). There were no differences in HADS anxiety or depression scores. In older MFS patients, with a more severe cardiovascular phenotype, chronic pain, and a higher unemployment rate, significantly more symptoms of depression were observed, when compared with the general population (p = 0.027) or compared with younger MFS patients (p = 0.026). Multivariate analysis, showed that anxiety was associated with chronic pain (p = 0.022) and symptoms of depression with unemployment (p = 0.024). MFS patients report significantly more severe fatigue as compared with the general population. Since the cause of fatigue is unclear, more research may be needed. Psychological intervention, for example, cognitive behavioral therapy, may contribute to a reduction in psychological symptoms.

The effect of cognitive behavior therapy on anxiety and depression during COVID-19 pandemic: a systematic review and meta-analysis

BACKGROUND

The global spread of coronavirus has caused many physical and mental health problems throughout the world. Depression and anxiety are among the issues that people are experiencing abundantly, along with other mental health disorders, during this period. Cognitive behavior therapy (CBT) is one of the approaches that is effective on improving most of the psychological issues including depression and anxiety. The objective of this systematic review and meta-analysis was to assess the effects of CBT on depression and anxiety during COVID-19 pandemic period.

METHODS

English databases such as Cochrane, PubMed, Google Scholar, Web of Science and Persian databases such as SID, MagIran and IranDoc were searched with a time limit of 2019 to 2022. Two researchers independently evaluated the quality of the entered studies based on Cochrane handbook. Subgroup analysis was conducted separately on the basis of being infected with coronavirus, not being infected with coronavirus, and having a history of depression or anxiety before the intervention and internet-based CBT for depression and anxiety. Meta-analysis results were reported using standardized mean difference (SMD) and 95% confidence interval (95% CI). Heterogeneity of studies was analyzed by means of I2 index; and in the case of heterogeneity presence, random effects model was used instead of fixed effects model. Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used for evaluating the quality of evidence.

RESULTS

Totally, 2015 articles were analyzed of which 11 articles entered meta-analysis. The overall results of meta-analysis showed that mean score of anxiety in the group receiving CBT was significantly lower than the control group (SMD: - 0.95, 95% CI - 1.29 to - 0.62; P < 0.00001, I2 = 94%). In addition, mean score of depression in the intervention group was significantly lower than the control group (SMD: - 0.58; 95% CI - 1.00 to - 0.16, P < 0.00001, I2 = 94%). In addition, the results of subgroup meta-analysis showed that internet-based CBT was effective in reducing of depression (SMD - 0.35; 95% CI - 0.50 to - 0.20; P < 0.00001; I2 = 0%) and anxiety (SMD - 0.90; 95%CI - 1.47 to - 0.33; P = 0.002; I2 = 94%). The evidence about the effectiveness of CBT on depression and anxiety compared with control group on the basis of GRADE approach had low quality.

CONCLUSIONS

Meta-analysis results showed that CBT reduced the mean scores of anxiety and depression significantly during COVID-19 pandemic period. Due to the low quality of evidence, conducting more randomized controlled trials with rigorous design is suggested.

Patient characteristics and changes in anxiety symptoms in patients with panic disorder: Post-hoc analysis of the PARADIES cluster randomised trial

Anxiety disorders are among the most common mental health problems in primary care. The PARADIES (Patient Activation foR Anxiety DIsordErS) intervention combined elements of cognitive behavioural therapy with case management and has demonstrated efficacy. Our aim was to explore patient characteristics, which may influence the course of anxiety symptoms over a 12 months period. Multiple linear regression was used to quantify associations of baseline characteristics (demographics, clinical parameters, medication use) with changes in anxiety symptoms as measured by the Beck anxiety inventory. Treatment modalities (e.g. adherence to appointment schedules) were considered as confounders. We examined univariate associations between dependent and independent variables before considering all independent variables in a multivariate final model. To find the best model to explain BAI score changes, we performed step-wise selection of independent variables based on Akaike information criteria. We tested for interaction terms between treatment allocation (intervention vs control) and independent variables using the multivariate model. We repeated these analyses in control vs intervention groups separately. From the original trial (N = 419), 236 patients (56.3%) were included. In the multivariate model, receiving the intervention (p<0.001), higher anxiety symptom severity (p<0.001) and longer illness duration at baseline (p = 0.033) were significantly associated with changes in anxiety symptom severity to the better while depression severity at baseline (p<0.001) was significantly associated with changes in anxiety symptoms to the worse. In stratified analyses, the control group showed significant associations between depression symptom severity and illness duration with anxiety symptom changes while baseline severity of anxiety symptoms remained significantly associated with anxiety symptom changes in both groups. A brief primary-care-based exposure training combined with case management is effective in a broad range of patients with panic disorder with/without agoraphobia, including those with longer illness duration and co-existing symptoms of depression at baseline.

Group intervention programs and their impact on well-being and quality-of-life for adults living with a rare or orphan disease - realist review of literature

PURPOSE

Adults living with a rare or orphan diseases (ROD) experience common psychosocial difficulties that are often poorly addressed in usual care. This realist literature review aims to inform the development, evaluation and implementation of evidence based group therapy programs adapted to shared needs of patients living with various ROD.

METHOD

The review is based on an analysis of Context-Mechanism-Outcome configurations. It included 21 primary studies published between 2010 and April 2022 and used a PRISMA process for study selection and inclusion.

RESULTS

Our results show that group psychosocial interventions can help reduce perception of symptoms and psychological impacts of disease, improve social functioning and support and quality of life in patients.

CONCLUSION

Group therapy programs seem promising for ROD-patients and should be considered within comprehensive treatment and support plans. However, more comprehensive studies of group therapies in context should aim to identify core active components of these interventions with ROD-patients. Implications for Rehabilitation:Rare or Orphan Diseases are varied, difficult to diagnose and have a major impact on all aspects of the patients' lives (physical, emotional, psychological, social, professional).Psychosocial support is a key but underdeveloped component to support the recovery trajectory for these patients.In this review of group interventions, we identified a few promising practices adaptable to patients living with Rare or Orphan Diseases (Acceptance and commitment therapy, cognitive behavioural therapies, psychoeducational programs).Patients who received psychosocial group interventions are likely to experience improvement in their quality of life.

Religious-based interventions for depression: A systematic review and meta-analysis of experimental studies

BACKGROUND

Depression is the most prevalent mental disorder. In the treatment of depressive symptoms, patients' religious practices and beliefs are often not considered. We carried out a systematic review and meta-analysis of RCTs to analyse the effect of religious interventions on depression.

METHODS

A literature screening was performed on August 2021, using the Cochrane Collaboration, PubMed, Scopus, and Web of Science databases. Primary source articles published from 2015 to August 2021 in peer-reviewed journals were eligible for inclusion if data were presented on religious interventions' effects on depression.

RESULTS

The literature search yielded 208 potentially relevant publications. Eight articles were identified and included in the review. One of the articles was excluded from the meta-analysis because it did not report the mean data for the baseline and follow-up assessment results. From the 7 out of 8 included studies, the results consistently indicated that religious-based interventions effectively reduced depressive symptoms among vulnerable persons with chronic medical illness, pregnant women, haemodialysis patients, elderly nursing home residents, people with major depressive disorders or dysthymia, and coronary artery bypass graft surgery patients.

LIMITATIONS

The definition of the religious-based intervention varied substantially among the trials. These differences can make interpretation and comparing implications on the treatment of depression difficult.

CONCLUSION

Compared to standard/other usual therapies for treating depression, religious-based interventions provide superior effects. This review and meta-analysis strongly suggest that patients' religious beliefs should be considered when diagnosing and treating depression.

Utilization of passive visual perception task indetecting patients with major depressive disorder for active health

Depression is a common emotional and mental disease. At present, doctors' diagnosis mainly depends on the existing evaluation scales and their accumulated experience, lack of objective electrophysiological quantitative evaluation indicators. This study explores the difference in event-related potential (ERP) between patients with depression and healthy controls under the stimulation of multi-dimensional tasks, extracts the characteristic data, and uses a t-test for statistical analysis to provide an objective evaluation index for the clinical diagnosis of depression. Ninety-nine patients in the major depression group (MDD) and thirty patients in the healthy control group (HC) were used to compare the responses to positive, negative, and neutral stimulation, the results showed that there were significant differences between the left and right occipital lobes and one frontal lobe, and the frontal lobe showed lateralization; There were significant differences between the depression group and the healthy control group under multi-dimensional stimulation (P < 0.01), and the depression patients were significantly lower than the healthy patients. The results showed that emotional information was processed differently in patients with depression in the early stages of visual face processing. Therefore, EEG indices could be used as an objective index for the early detection of depression. Moreover, according to the instructions before the test, the subject is only asked to recognize visual pictures instead report emotional feelings. Stigma about psychiatric disorders could thus be reduced in this way. The explorations above facilitate designing more accurate and implicit active mental health techniques.

Efficacy of Internet-Based Cognitive Behavioral Therapy for Depression and Anxiety among Global Population during the COVID-19 Pandemic: A Systematic Review and Meta-Analysis of a Randomized Controlled Trial Study

Background: Depression and anxiety have become the most common mental health disorders worldwide during the COVID-19 pandemic, and increasing interest in telemedicine has led to the innovation of using internet-based cognitive behavioral therapy (iCBT). Objective: This systematic review and meta-analysis aimed to evaluate the efficacy of iCBT for depression and anxiety among the global population during the COVID-19 pandemic. Methods: A literature search was conducted on PubMed, Scopus, Cochrane, ProQuest, Wiley, and Web of Science using the PRISMA framework, and only randomized controlled trials (RCTs) were included in the study. A critical appraisal was also performed using Cochrane’s Risk of Bias (RoB) 2. The meta-analysis used random-effects models to analyze pooled mean difference (MD) and its p-value. Results: Twelve RCTs were included for qualitative analysis and nine RCTs, which yielded 6778 patients with depression and 6556 patients with anxiety during the COVID-19 pandemic, were included for quantitative analysis. Despite high heterogeneity, all studies had a low risk of bias. Pre- and post-iCBT intervention in the depression forest plot depicts a significant effect (p < 0.00001) with a pooled MD of 4.73 (95% CI: 4.55−4.90), while the pre- and post-iCBT intervention depicts a significant effect (p < 0.00001) with a pooled MD of 4.50 (95% CI: 4.34−4.67). This demonstrates that iCBT was found to significantly decrease depression and anxiety scores in patients during the COVID-19 pandemic. However, substantial heterogeneity was also found (I2 = 93%; p < 0.00001 and I2 = 90%) for the pre-/post-depression and anxiety forest plots, respectively. Conclusions: This meta-analysis comprises an evidence-based result for iCBT to treat depression and anxiety in the COVID-19 population, as indicated by the significantly lower assessment scores. Delivering iCBT in this situation needs to be considered more extensively, as it has promising results and yields the benefits of technological advancement in psychotherapy.

A pragmatic preference trial of therapeutic yoga as an adjunct to group cognitive behaviour therapy versus group CBT alone for depression and anxiety

BACKGROUND

Yoga has several mechanisms that make it a promising treatment for depression and anxiety, including physical activity, behavioural activation, and mindfulness. Following positive outcomes from adapted CBT interventions incorporating mindfulness-based practices, this study explored the effects of a therapeutic yoga program as an adjunct to group-based CBT for depression or anxiety.

METHODS

This was a pragmatic preference trial involving adults diagnosed with depression or anxiety in a regional primary mental healthcare service (n = 59), comparing transdiagnostic group CBT (n = 27) with transdiagnostic group CBT combined with an adjunct therapeutic yoga program (n = 32). A preference recruitment design allowed eligible participants (n = 35) to self-select into the adjunct program. The Depression Anxiety Stress Scale-21 (DASS) was assessed at baseline, post-intervention, and three-months follow up.

RESULTS

CBT + Yoga was an acceptable alternative to CBT alone. Significant reductions were observed in total DASS scores and the 3 subscales of the DASS for both groups, however CBT + Yoga showed significantly lower depressive and anxiety symptoms post-intervention, compared to CBT alone. CBT + Yoga also showed sustained reductions in depressive symptoms over three-months, and more rapid reductions in depressive symptoms, compared to CBT alone.

LIMITATIONS

These findings should be considered preliminary due to the moderate sample size, with a rigorous randomised control trial necessary to definitively support the integration of yoga within mental health care to augment the benefits and uptake of transdiagnostic CBT for depression and anxiety.

CONCLUSIONS

Complementing other mindfulness-based practices, therapeutic yoga shows promise as an adjunct to transdiagnostic CBT.

Use of behavioural activation to manage pain: a systematic scoping review

BACKGROUND

Behavioural activation (BA) is an effective treatment for depression; however, it is unclear if it can be used to manage pain.

OBJECTIVES

To conduct a scoping review of primary research that reported using BA to support people living with chronic pain to understand how BA had been used in relation to pain. In addition, we wanted to understand whether there were any reported changes in that pain, and how and who delivered BA.

We searched seven databases MEDLINE, Ovid Embase, Ovid Emcare, PsycINFO, CINAHL, Scopus and Web of Science, for primary research. No initial date limit was used with the date the searches were conducted used as the end date limit (1 July 2021).

CHARTING METHODS

A customised data extraction table was developed, piloted and used.

RESULTS

551 papers were screened for inclusion, with 15 papers included in our review. Studies were conducted in North America and in Canada. These included three case studies, nine uncontrolled trials and three randomised controlled trials. Only two studies reported pain as the primary outcome. BA was applied across a range of pain related conditions. The dose of BA ranged from 3 to 16 sessions. Duration of treatment was 3 weeks to 12 months. Most studies reported reductions in pain following exposure to BA.

CONCLUSION

BA has the potential to reduce pain. Caution needs to be exercised in the interpretation of these findings as a high risk of bias was observed in most studies. High-quality research is required to test if BA is an effective intervention for chronic pain.

Effects of COVID-19 Mental Health Interventions Among Children, Adolescents, and Adults Not Quarantined or Undergoing Treatment Due to COVID-19 Infection: A Systematic Review of Randomised Controlled Trials

OBJECTIVES

Our objective was to assess the effects of mental health interventions for children, adolescents, and adults not quarantined or undergoing treatment due to COVID-19 infection.

METHODS

We searched 9 databases (2 Chinese-language) from December 31, 2019, to March 22, 2021. We included randomised controlled trials of interventions to address COVID-19 mental health challenges among people not hospitalised or quarantined due to COVID-19 infection. We synthesized results descriptively due to substantial heterogeneity of populations and interventions and risk of bias concerns.

RESULTS

We identified 9 eligible trials, including 3 well-conducted, well-reported trials that tested interventions designed specifically for COVID-19 mental health challenges, plus 6 other trials with high risk of bias and reporting concerns, all of which tested standard interventions (e.g., individual or group therapy, expressive writing, mindfulness recordings) minimally adapted or not specifically adapted for COVID-19. Among the 3 well-conducted and reported trials, 1 (N  =  670) found that a self-guided, internet-based cognitive-behavioural intervention targeting dysfunctional COVID-19 worry significantly reduced COVID-19 anxiety (standardized mean difference [SMD] 0.74, 95% confidence interval [CI], 0.58 to 0.90) and depression symptoms (SMD 0.38, 95% CI, 0.22 to 0.55) in Swedish general population participants. A lay-delivered telephone intervention for homebound older adults in the United States (N  =  240) and a peer-moderated education and support intervention for people with a rare autoimmune condition from 12 countries (N  =  172) significantly improved anxiety (SMD 0.35, 95% CI, 0.09 to 0.60; SMD 0.31, 95% CI, 0.03 to 0.58) and depressive symptoms (SMD 0.31, 95% CI, 0.05 to 0.56; SMD 0.31, 95% CI, 0.07 to 0.55) 6-week post-intervention, but these were not significant immediately post-intervention. No trials in children or adolescents were identified.

CONCLUSIONS

Interventions that adapt evidence-based strategies for feasible delivery may be effective to address mental health in COVID-19. More well-conducted trials, including for children and adolescents, are needed.

Evaluating telehealth lifestyle therapy versus telehealth psychotherapy for reducing depression in adults with COVID-19 related distress: the curbing anxiety and depression using lifestyle medicine (CALM) randomised non-inferiority trial protocol

BACKGROUND

There is increasing recognition of the substantial burden of mental health disorders at an individual and population level, including consequent demand on mental health services. Lifestyle-based mental healthcare offers an additional approach to existing services with potential to help alleviate system burden. Despite the latest Royal Australian New Zealand College of Psychiatrists guidelines recommending that lifestyle is a 'first-line', 'non-negotiable' treatment for mood disorders, few such programs exist within clinical practice. Additionally, there are limited data to determine whether lifestyle approaches are equivalent to established treatments. Using an individually randomised group treatment design, we aim to address this gap by evaluating an integrated lifestyle program (CALM) compared to an established therapy (psychotherapy), both delivered via telehealth. It is hypothesised that the CALM program will not be inferior to psychotherapy with respect to depressive symptoms at 8 weeks.

METHODS

The study is being conducted in partnership with Barwon Health's Mental Health, Drugs & Alcohol Service (Geelong, Victoria), from which 184 participants from its service and surrounding regions are being recruited. Eligible participants with elevated psychological distress are being randomised to CALM or psychotherapy. Each takes a trans-diagnostic approach, and comprises four weekly (weeks 1-4) and two fortnightly (weeks 6 and 8) 90-min, group-based sessions delivered via Zoom (digital video conferencing platform). CALM focuses on enhancing knowledge, behavioural skills and support for improving dietary and physical activity behaviours, delivered by an Accredited Exercise Physiologist and Accredited Practising Dietitian. Psychotherapy uses cognitive behavioural therapy (CBT) delivered by a Psychologist or Clinical Psychologist, and Provisional Psychologist. Data collection occurs at baseline and 8 weeks. The primary outcome is depressive symptoms (assessed via the Patient Health Questionnaire-9) at 8 weeks. Societal and healthcare costs will be estimated to determine the cost-effectiveness of the CALM program. A process evaluation will determine its reach, adoption, implementation and maintenance.

DISCUSSION

If the CALM program is non-inferior to psychotherapy, this study will provide the first evidence to support lifestyle-based mental healthcare as an additional care model to support individuals experiencing psychological distress.

Effectiveness of Videoconference-Delivered Cognitive Behavioral Therapy for Adults With Psychiatric Disorders: Systematic and Meta-Analytic Review

Background

Cognitive behavioral therapy (CBT) is the gold standard of psychotherapy for psychiatric disorders. However, the format of delivering CBT in person limits access to the intervention. The advancements in information and communication technology, especially the internet, present an opportunity for cognitive behavioral therapists to service patients or clients in remote areas through videoconferencing. Although many randomized controlled trials of videoconference-delivered cognitive behavioral therapy (VCBT) have already been conducted, the overall estimated effect size of VCBT for psychiatric disorders has not been examined by systematic reviews and meta-analyses.

Objective

This study attempts to evaluate the effectiveness of VCBT for psychiatric disorders through a systematic and meta-analytic review.

Methods

A systematic review and meta-analysis of studies in which VCBT was directly compared to control groups (such as treatment as usual, attention control, wait-list control, and other minimal supports) was carried out. To identify previous studies that meet our study objective, 2 independent reviewers undertook a systematic search through seven databases: MEDLINE (via PubMed), Web of Science, Science Direct, PsycINFO, CINAHL, LILACS, and SciELO. Other databases (ClinicalTrials.gov and Cochrane Central Resister of Controlled Trials) were also checked. All studies included in the review were assessed using the quality criteria of the Cochrane Collaboration. Statistical analysis was performed by using Cochrane Review Manager (RevMan, version 5.4.0). Standardized mean difference was used in major meta-analyses where a P value of .05 or less was the threshold for statistical significance. A heterogeneity test and the chi-square test were performed to assess the presence and extent of statistical heterogeneity with significance set at P<.10. Funnel plots were visually inspected to assess the risk of bias. Subgroup analyses were conducted for each disorder to estimate intervention effects.

Results

The systematic search resulted in 16 studies (total N=1745) that met the criteria for this study and were included in the review. There were 10 studies on depressive symptoms, 3 on chronic pain, 1 on generalized anxiety disorder, 1 on obsessive-compulsive disorder, and 1 on hypochondriasis. The quality and risk of bias was also assessed. Results showed a pooled effect size (Hedge g) post treatment of −0.49 (95% CI –0.68 to –0.29), indicating that VCBT is effective for clients with psychiatric disorders. Study quality did not affect outcomes.

Conclusions

While the overall results indicate the effectiveness of VCBT, there are still only a limited number of studies on specific psychiatric and somatic conditions. Therefore, more randomized controlled trials are needed to establish the effectiveness of VCBT for different disorders.

The Effectiveness of Mindfulness-Based Cognitive Therapy in Primary Care and the Role of Depression Severity and Treatment Attendance

OBJECTIVES

Evidence suggests the efficacy of mindfulness-based cognitive therapy (MBCT) to prevent depression relapse and decrease depressive symptoms during the acute phase. However, the effectiveness of MBCT in real-world heterogeneous samples treated in clinical health settings, including primary care, has received little attention. This study had two aims: (1) to evaluate the effectiveness of MBCT delivered in primary care considering pre-treatment depression scores and (2) to explore the role of participants' characteristics on symptom improvement.

METHODS

Data were obtained from 433 individuals who received MBCT. Participants completed the Personality Inventory for ICD-11 (PiCD) pretreatment and the Beck Depression Inventory (BDI-II) pre- and post-treatment.

RESULTS

Sixty percent presented moderate-to-severe depression according to scores on the BDI-II, 18.1% presented mild depression, and 21.7% were in the non-depressed range. The severity of pre-treatment depressive symptoms was associated with outcomes. Most individuals who lacked depressive symptoms at baseline remained in the non-clinical range after the treatment. Those in the severe group benefited the most from the intervention, since 35.6% were considered recovered. Rates of deterioration ranged from 2.1 to 2.7%, depending on the depression-baseline scores. Depression severity at the entrance, attendance, and age, but not personality traits, appear to be related to symptom improvement.

CONCLUSIONS

According to our results, MBCT can be effectively and safely delivered in primary care.

Gut Hormones as Potential Therapeutic Targets or Biomarkers of Response in Depression: The Case of Motilin

Recent research has identified the gut–brain axis as a key mechanistic pathway and potential therapeutic target in depression. In this paper, the potential role of gut hormones as potential treatments or predictors of response in depression is examined, with specific reference to the peptide hormone motilin. This possibility is explored through two methods: (1) a conceptual review of the possible links between motilin and depression, including evidence from animal and human research as well as clinical trials, based on a literature search of three scientific databases, and (2) an analysis of the relationship between a functional polymorphism (rs2281820) of the motilin (MLN) gene and cross-national variations in the prevalence of depression based on allele frequency data after correction for potential confounders. It was observed that (1) there are several plausible mechanisms, including interactions with diet, monoamine, and neuroendocrine pathways, to suggest that motilin may be relevant to the pathophysiology and treatment of depression, and (2) there was a significant correlation between rs2281820 allele frequencies and the prevalence of depression after correcting for multiple confounding factors. These results suggest that further evaluation of the utility of motilin and related gut peptides as markers of antidepressant response is required and that these molecular pathways represent potential future mechanisms for antidepressant drug development.

Self-guided Cognitive Behavioral Therapy Apps for Depression: Systematic Assessment of Features, Functionality, and Congruence With Evidence

Background

Mental health disorders affect 1 in 10 people globally, of whom approximately 300 million are affected by depression. At least half of the people affected by depression remain untreated. Although cognitive behavioral therapy (CBT) is an effective treatment, access to mental health specialists, habitually challenging, has worsened because of the COVID-19 pandemic. Internet-based CBT is an effective and feasible strategy to increase access to treatment for people with depression. Mental health apps may further assist in facilitating self-management for people affected by depression; however, accessing the correct app may be cumbersome given the large number and wide variety of apps offered by public app marketplaces.

Objective

This study aims to systematically assess the features, functionality, data security, and congruence with evidence of self-guided CBT-based apps targeting users affected by depression that are available in major app stores.

Methods

We conducted a systematic assessment of self-guided CBT-based apps available in Google Play and the Apple App Store. Apps launched or updated since August 2018 were identified through a systematic search in the 42matters database using CBT-related terms. Apps meeting the inclusion criteria were downloaded and assessed using a Samsung Galaxy J7 Pro (Android 9) and iPhone 7 (iOS 13.3.1). Apps were appraised using a 182-question checklist developed by the research team, assessing their general characteristics, technical aspects and quality assurance, and CBT-related features, including 6 evidence-based CBT techniques (ie, psychoeducation, behavioral activation, cognitive restructuring, problem solving, relaxation, and exposure for comorbid anxiety) as informed by a CBT manual, CBT competence framework, and a literature review of internet-based CBT clinical trial protocols. The results were reported as a narrative review using descriptive statistics.

Results

The initial search yielded 3006 apps, of which 98 met the inclusion criteria and were systematically assessed. There were 20 well-being apps; 65 mental health apps, targeting two or more common mental health disorders, including depression; and 13 depression apps. A total of 28 apps offered at least four evidence-based CBT techniques, particularly depression apps. Cognitive restructuring was the most common technique, offered by 79% (77/98) of the apps. Only one-third of the apps offered suicide risk management resources, whereas 17% (17/98) of the apps offered COVID-19–related information. Although most apps included a privacy policy, only a third of the apps presented it before account creation. In total, 82% (74/90) of privacy policies stated sharing data with third-party service providers. Half of the app development teams included academic institutions or health care providers.

Conclusions

Only a few self-guided CBT-based apps offer comprehensive CBT programs or suicide risk management resources. Sharing of users’ data is widespread, highlighting shortcomings in health app market governance. To fulfill their potential, self-guided CBT-based apps should follow evidence-based clinical guidelines, be patient centered, and enhance users’ data security.

New Evidence in the Booming Field of Online Mindfulness: An Updated Meta-analysis of Randomized Controlled Trials

BACKGROUND

There is a need to regularly update the evidence base on the effectiveness of online mindfulness-based interventions (MBIs), especially considering how fast this field is growing and developing.

OBJECTIVE

This study presents an updated meta-analysis of randomized controlled trials assessing the effects of online MBIs on mental health and the potential moderators of these effects.

METHODS

We conducted a systematic literature search in PsycINFO, PubMed, and Web of Science up to December 4, 2020, and included 97 trials, totaling 125 comparisons. Pre-to-post and pre-to-follow-up between-group effect sizes (Hedges g) were calculated for depression, anxiety, stress, well-being, and mindfulness using a random effects model.

RESULTS

The findings revealed statistically significant moderate pre-to-post effects on depression (g=0.34, 95% CI 0.18-0.50; P<.001), stress (g=0.44, 95% CI 0.32-0.55; P<.001), and mindfulness (g=0.40, 95% CI 0.30-0.50; P<.001) and small effects on anxiety (g=0.26, 95% CI 0.18-0.33; P<.001). For well-being, a significant small effect was found only when omitting outliers (g=0.22, 95% CI 0.15-0.29; P<.001) or low-quality studies (g=0.26, 95% CI 0.12-0.41; P<.001). Significant but small follow-up effects were found for depression (g=0.25, 95% CI 0.12-0.38) and anxiety (g=0.23, 95% CI 0.13-0.32). Subgroup analyses revealed that online MBIs resulted in higher effect sizes for stress when offered with guidance. In terms of stress and mindfulness, studies that used inactive control conditions yielded larger effects. For anxiety, populations with psychological symptoms had higher effect sizes. Adherence rates for the interventions ranged from 35% to 92%, but most studies lacked clear definitions or cut-offs.

CONCLUSIONS

Our findings not only demonstrate that online MBIs are booming but also corroborate previous findings that online MBIs are beneficial for improving mental health outcomes in a broad range of populations. To advance the field of online MBIs, future trials should pay specific attention to methodological quality, adherence, and long-term follow-up measurements.

Brief cognitive behavioral therapy in pregnant women at risk of postpartum depression: Pre-post therapy study in a city in southern Brazil

BACKGROUND

Postpartum depression (PPD) affects a high number of women, often the first manifestation of a mood disorder that will occur later in life, bringing serious consequences for the patient and her offspring. Depression today is the leading cause of disability worldwide. The aim of this study was to evaluate the effectiveness of a preventive cognitive behavioral therapy (CBT) for PPD.

METHODS

Pre-post therapy study, as part of a population-based cohort study. Pregnant women without a diagnosis of depression participated, who were divided into two groups: risk of depression (CBT) and a control group (without therapy). The preventive therapy consisted of six sessions of CBT, administered weekly. The Outcome Questionnaire (OQ-45) was used in all sessions. The Mini International Neuropsychiatric Interview and Beck Depression Inventory-II were used on three occasions. The final statistical analyses were performed by Poisson regression.

RESULTS

The prevalence of PPD in the risk group was 5.5% and in the control group 2.2%, with no difference between the groups (PR 1.66 95% CI 0.44-6.18). The OQ-45 averages gradually reduced during the therapy sessions, indicating therapeutic progress. Schooling was an associated factor, both with the manifestation of PPD and with the greater effectiveness of the therapy.

LIMITATIONS

Rate of 40.5% refusal to preventive treatment and absence of a group with similar characteristics in another therapy model.

CONCLUSIONS

Brief cognitive behavioral therapy applied by mental health professionals with basic training was effective in preventing the manifestation of PPD.

Psychological and social interventions for mental health issues and disorders in Southeast Asia: a systematic review

BACKGROUND

Mental health issues and disorders are major public health challenges, particularly in low- and middle-income countries in Southeast Asia, where chronic shortages in mental health services and human resources exist. The development of effective and accessible mental health systems in Southeast Asia will require evidence based psychological and social interventions. This systematic review provides a narrative synthesis of the evidence on the effectiveness of such interventions for mental health issues and disorders in Southeast Asia.

METHODS

A comprehensive literature search of 7 electronic databases (PsycINFO, Medline (Ovid), Cochrane library, EMBASE, SCOPUS, APA PsycArticles, and Social Care Online) was undertaken.

RESULTS

Thirty two studies employing RCT designs to evaluate the effectiveness of a range of psychological and social mental health interventions on a number of different mental health outcomes were included in this review. The disparate intervention programmes reviewed were categorised as: lay delivered, yoga, aerobic and/or meditation based, cognitive behavioural therapy oriented, eye movement desensitization and reprocessing based (EMDR), health worker delivered, and hybrid programmes. The majority of the studies included in this review were of low to moderate quality due to the variability in the quality of the study design. The highest quality, and most promising evidence came from the evaluations of lay delivered interventions. This evidence demonstrates the feasibility and potential sustainability of implementing such interventions in resource constrained contexts.

CONCLUSIONS

The review findings indicate that a disparate array of mental health interventions can be implemented effectively in a range of Southeast Asian mental health and health settings. There is a clear need for significantly more research however, through higher quality and larger scale RCTs before it will be known more definitively, if these interventions are effective, and for whom they are most effective in different Southeast Asian contexts.

The importance of transdiagnostic symptom level assessment to understanding prognosis for depressed adults: analysis of data from six randomised control trials

BACKGROUND

Depression is commonly perceived as a single underlying disease with a number of potential treatment options. However, patients with major depression differ dramatically in their symptom presentation and comorbidities, e.g. with anxiety disorders. There are also large variations in treatment outcomes and associations of some anxiety comorbidities with poorer prognoses, but limited understanding as to why, and little information to inform the clinical management of depression. There is a need to improve our understanding of depression, incorporating anxiety comorbidity, and consider the association of a wide range of symptoms with treatment outcomes.

METHOD

Individual patient data from six RCTs of depressed patients (total n = 2858) were used to estimate the differential impact symptoms have on outcomes at three post intervention time points using individual items and sum scores. Symptom networks (graphical Gaussian model) were estimated to explore the functional relations among symptoms of depression and anxiety and compare networks for treatment remitters and those with persistent symptoms to identify potential prognostic indicators.

RESULTS

Item-level prediction performed similarly to sum scores when predicting outcomes at 3 to 4 months and 6 to 8 months, but outperformed sum scores for 9 to 12 months. Pessimism emerged as the most important predictive symptom (relative to all other symptoms), across these time points. In the network structure at study entry, symptoms clustered into physical symptoms, cognitive symptoms, and anxiety symptoms. Sadness, pessimism, and indecision acted as bridges between communities, with sadness and failure/worthlessness being the most central (i.e. interconnected) symptoms. Connectivity of networks at study entry did not differ for future remitters vs. those with persistent symptoms.

CONCLUSION

The relative importance of specific symptoms in association with outcomes and the interactions within the network highlight the value of transdiagnostic assessment and formulation of symptoms to both treatment and prognosis. We discuss the potential for complementary statistical approaches to improve our understanding of psychopathology.
