Twelve-month prevalence, comorbidity and correlates of mental disorders in Germany: the Mental Health Module of the German Health Interview and Examination Survey for Adults (DEGS1-MH)

Waning waves of mood: The declining trend of hospitalized patients with affective disorders in Germany

INTRODUCTION

Affective disorders profoundly affect individuals' emotional well-being and quality of life. This study investigates the epidemiology of affective disorders in Germany from 2011 to 2021, focusing on incidence rates, age- and sex-standardized rates, and developmental trends.

METHODS

Using nationwide data of ICD-10 diagnosis codes from 2011 to 2021, this cross-sectional study analyzed inpatient cases of affective disorders in individuals aged 20 years or older. Age- and sex-standardized incidence rates were calculated based on the population size of each birth cohort in the 16 German federal states. Incidence rate ratios (IRRs) for 2011 to 2021 and 2019 to 2021 were compared with a two-sample z-test.

RESULTS

Between 2011 and 2021, F30 (manic episode) showed a decline of 42.8 % to an incidence of 4.9 per 100,000 inhabitants, even though not statistically significant (p = 0.322). F31 (bipolar affective disorder) remained relatively stable with a reduction of 15.3 % to an incidence of 13.6 per 100,000 inhabitants in 2021 (p = 0.653). F32 (depressive episode) decreased statistically significant by 25.7 % to an incidence of 64.1 per 100,000 inhabitants (p = 0.072). F33 (recurrent depressive disorder) slightly increased by 18.3 % to an incidence of 94.6 per 100,000 inhabitants (p = 0.267). No statistically significant differences were found when comparing the COVID-19 pandemic year 2021 to 2019 incidences (p ≥ 0.529).

CONCLUSION

The study provides valuable insights into the changing landscape of affective disorders in Germany over the past decade. The observed decline in incidence rates underscores the importance of continued efforts to promote mental health awareness and access to care.

Do the elderly and those with comorbid chronic physical conditions have improved access to outpatient psychotherapy post structural reforms in Germany? Results of the ES-RiP study

Background

In 2017, a reform of the German outpatient psychotherapy guideline was carried out, aiming to reduce waiting times and facilitate low-threshold access. This study analyzes the extent to which the implementation of the two new service elements 'psychotherapeutic consultation times' and 'acute short-term psychotherapeutic interventions' improved psychotherapeutic care for patients with mental disorders and chronic physical conditions (cMPs), for patients with mental disorders without chronic physical conditions (MnoP), and elderly patients.

Methods

In a quantitative secondary analysis, we analyzed health insurance data of patients with psychotherapy billing codes obtained from the National Association of Statutory Health Insurance Physicians (KBV) for the years 2015-2019, evaluating descriptive statistical parameters for specific patient groups and care services.

Results

Between 2015 and 2019, the number of mentally ill receiving psychotherapy at least once in the corresponding year increased by 30.7%. Among these, the proportion of cMPs-patients increased from 26.8% to 28.2% (+1.4%), while that of MnoP-patients decreased from 68.3% to 66.4% (-1.9%). The number of elderly people receiving treatment also increased.

Conclusion

Since increases and decreases in the percentage shares occur evenly over the years investigated, it is questionable whether the reform in 2017 has had a direct influence on these changes.

Independent and Joint Associations of Physical Activity and Sleep on Mental Health Among a Global Sample of 200,743 Adults

BACKGROUND

Previous research has demonstrated that both sleep and physical activity (PA) are independently associated with various indicators of mental health among adults. However, their joint contribution to mental health has received limited attention. The present study used cross-sectional data from the Mental Health Million Project to examine the independent and joint effects of sleep and PA on mental health among a global sample of adults, and whether these effects differ among individuals receiving mental health treatment.

METHOD

The sample included 200,743 participants (33.1% young adults, 45.6% middle-aged adults, 21.3% older adults; 57.6% females, 0.9% other) from 213 countries, territories, and archipelagos worldwide that completed a comprehensive 47-item assessment of mental health including both problems (i.e., ill-being) and assets (i.e., well-being): the Mental Health Quotient. Participants also reported their weekly frequency of PA and adequate sleep, and mental health treatment status. A series of generalized linear mixed models were computed.

RESULTS

Independent dose-response associations were observed, whereby greater amounts of PA and adequate sleep were each associated with better mental health. In addition, a synergistic interaction was observed in which the positive correlation of PA with mental health was strengthened with greater frequency of adequate sleep. These benefits were less pronounced among adults receiving mental health treatment.

CONCLUSION

While findings suggest sleep can help to offset the negative influence of a physically inactive lifestyle (and vice versa), our results point to a "more is better" approach for both behaviors when it comes to promoting mental health.

TONI - One for all? Participatory development of a transtheoretic and transdiagnostic online intervention for blended care

Background

Internet-based interventions offer a way to meet the high demand for psychological support. However, this setting also has disadvantages, such as the lack of personal contact and the limited ability to respond to crises. Blended care combines Internet-based interventions with face-to-face psychotherapy and merges the benefits of both settings. To ensure the uptake of blended care in routine care, Internet-based interventions need to be suitable for different therapeutic approaches and mental disorders.

Objective

This paper describes the participatory development process of the Internet-based intervention "TONI" using a common therapeutic language and content on various transdiagnostic topics to be integrated into routine outpatient psychotherapy.

Methods

To develop this intervention in a participatory manner, we followed the Integrate, Design, Assess, and Share (IDEAS) framework. In a multilevel development process, we used a combination of interviews, focus groups, and proofreading to optimally tailor online modules to routine outpatient psychotherapy. Building on well-established cognitive-behavioral online content, we included expert interviews with psychodynamic (n = 20) and systemic psychotherapists (n = 9) as well as focus groups with psychotherapists of different approaches (n = 10) and persons with lived experience of mental illness (PWLE; n = 10).

Results

We describe the development process of TONI step-by-step, outlining the specific requirements that therapists from different therapeutic approaches as well as PWLE have and how we implemented them in our intervention. This includes the content and specific exercises in the online modules, aspects of data protection, language, design, and usability.

Conclusion

Internet-based interventions that use a common therapeutic language and address therapeutic principles across different approaches have the potential to advance digitalization in psychotherapy. Involving psychotherapists and PWLE in intervention development may positively impact acceptance and usage in practice. This study shows how participatory intervention development involving both psychotherapists and PWLE can be carried out.

Making un/equal: reassessing inequality and mental health through a praxeographic approach on welfare categorization processes

PURPOSE

In recent decades, Europe has seen a steady increase in psychiatric diagnoses, which, besides affecting the population in many ways, also challenges the organization of welfare. This paper explores how welfare classification processes impact the contemporary production of mental (ill) health and social inequality in the German welfare state.

METHODS

Based on comprehensive ethnographic research in the public mental healthcare landscape in Berlin between 2011 and 2017, this paper discusses in detail the case of a mandatory prescription of a psychosocial rehabilitation measure for Ms Reisch, a psychiatric service user and ethnographic research partner. The analysis draws on the methodological approach of praxeography to examine how this case challenges the social determinants of mental health framework and the conceptual work of the sociology of inequality on which the categories of welfare are largely built.

RESULTS

The paper highlights the essentializing properties of social categories, whether in the sociology of inequality or in social and mental health policy. It also demonstrates the strength of praxeography to expose how multiple welfare categorization processes shape experiences and events of dis/ability in practice, potentially contradicting the stated intentions of social policy.

CONCLUSION

The results suggest that the attachment of categories to people in public welfare needs to be changed to make public administration more flexible to responding to the situated processes that bring about differentiations of equal and unequal in practice. The paper, therefore, encourages social inquiry into the potentialities of a post-categorical social policy framework.

Neuroenhancement and mental health in students from four faculties - a cross-sectional questionnaire study

Background

Students face great challenges at the beginning of and during their studies. Competitive experience, exam anxiety, and especially the new performance requirements often cause test anxiety and stressful experiences. The extent of substance use in terms of neuroenhancement (NE) is unclear. Evidence shows associations between NE, increased stress levels, and mental health.

Objectives

We aim to determine the prevalence of NE and alcohol and tobacco use among college students. We also investigate the associations between NE and ADHD, anxiety, depression, and stress experience.

Methods

In spring 2021, an anonymous online cross-sectional survey was conducted among students of medicine, dentistry, business economics, and business informatics in Würzburg. The survey included the instruments ASRS (ADHD), PSS-10 (stress), PHQ-4 (depression and anxiety), and AUDIT-C (alcohol comsumption), as well as questions about consumption patterns, prior knowledge, and reasons for NE.

Results

Of the 5564 students who were invited to participate, 1010 completed the questionnaire (18.2%). Of these, 12.4% indicated NE for the studied period. NE was used in particular during preparations for exams, to enhance performance, and/or to regulate emotions, most commonly through caffeine tablets, cannabis, and methylphenidate. NE was associated with risky use of alcohol or tobacco, and to a lesser extent with ADHD symptoms and stress experience.Conclusions: Students are at risk of substance abuse and NE. Effective stress management and prevention approaches as well as low-threshold services are needed to identify and support students with risk profiles.

Gender differences in the prevalence of mental distress in East and West Germany over time: a hierarchical age-period-cohort analysis, 2006-2021

PURPOSE

Mental distress has become a major public health concern. Temporal trends in psychological distress are complex and depend on numerous factors. In this study, we examined age-period-cohort effects for mental distress including gender and German region over a 15 years' time span.

METHODS

Data on mental distress from ten cross-sectional surveys of the general German population, covering the years from 2006 to 2021, was used. Hierarchical age-period-cohort analyses including gender and German region as predictors were performed to disentangle age, period, and cohort effects. The Patient Health Questionnaire-4 was used as a brief screener for mental distress.

RESULTS

We found significant period and cohort effects, with peek values for mental distress in the years 2017 and 2020 and for the oldest birth cohort (born before 1946). Age did not affect mental distress when cohort- and period effects as well as gender and German region were considered. An interaction effect for gender and the German region was found. Women in West Germany reported significantly higher mental distress compared to women in East Germany. Compared to men, women reported the highest prevalence in both regions.

CONCLUSION

Important political events as well as major crises can lead to an increase of mental distress in societies. Furthermore, an association between birth cohort and mental distress could be linked to socialization effects of that certain time, causing traumatic experiences or a specific coping style within this cohort group. Prevention and intervention strategies could benefit from acknowledging structural differences linked to period and cohort effects.

Validation of the Patient Health Questionnaire-4 for longitudinal mental health evaluation in elite Para athletes

BACKGROUND

Despite the increasing amount of research regarding mental health in elite athletes in recent years, athletes with impairments are hardly represented. Due to this lack of data and the significant need of athlete-specific mental health screening tools, a continuous mental health monitoring program for elite Para athletes was implemented.

OBJECTIVE

Validation of the Patient Health Questionnaire-4 (PHQ-4) as a suitable tool for continuous mental health evaluation in elite Para athletes.

DESIGN

A 43-week prospective observational cohort study.

SETTING

Online questionnaire, provided weekly via web browser and mobile app.

PARTICIPANTS

Seventy-eight Para athletes preparing for Paralympic Summer and Winter Games.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Weekly PHQ-4 scores, stress level, and mood.

RESULTS

With a mean weekly response rate of 82.7% (SD = 8.0), 2149 PHQ-4, 2159 stress level and 2153 mood assessments were completed. Mean PHQ-4 score among all participating athletes was 1.2 (SD = 1.8; 95% confidence interval [CI], [1.1-1.3]). Individual weekly scores ranged from 0 to 12 and showed significant floor effects, with 54% of the scores being zero. PHQ-4 scores were significantly higher among female athletes and team sport members (p < .001). Internal consistency of the PHQ-4 was satisfying, Cronbach's α being 0.839. There were significant cross-sectional as well as longitudinal correlations of PHQ-4 and stress level as well as mood values (p < .001). 39.7% of all athletes (n = 31) had at least one positive screen for mental health symptoms.

CONCLUSIONS

The PHQ-4 was shown to be a valid tool for mental health surveillance in elite Para athletes. Significant correlations of the PHQ-4 and stress level as well as mood were shown. High weekly response rates among participating athletes indicated good acceptance of the program. The weekly monitoring allowed for the identification of individual fluctuations and could identify potential athletes at risk for mental health problems when combined with clinical follow-up.

The crisis is over, long live the crisis: mental health in emerging adulthood during the course of the COVID-19 pandemic

Introduction

As a multidimensional stressor, the COVID-19 pandemic posed a significant threat to mental health, with studies showing younger age groups to be particularly vulnerable. Thus, this study aimed to monitor mental health, potential risk/protective factors, and pandemic-related variables among young university students during the pandemic.

Methods

Students of the University of Greifswald (M age = 23.0 years, 73.9% female) participated in five cross-sectional online surveys in December 2020 (N = 1,127), March 2021 (N = 760), June/July 2021 (N = 531), December 2021 (N = 1,226), and December 2022 (N = 814). Sociodemographic data, depression and anxiety severity, loneliness, quality of life, coping strategies, resilience, self-esteem, and emotion regulation were measured. First, results from December 2020 were compared to pre-pandemic normative data. Second, the time course during the pandemic was analyzed. Third, linear models were calculated to examine the influence of risk and protective factures on depression and anxiety severity.

Results

Higher levels of depression, anxiety, and loneliness, as well as lower levels of self-esteem, physical and mental health, social relationships and well-being were found in December 2020 compared to pre-pandemic. Levels of depression and anxiety severity peaked in December 2022. Female sex, loneliness, and previous mental treatment showed associations with higher depression and anxiety severity, while higher self-esteem, resilience and use of reappraisal strategies appeared to act as protective factors.

Discussion

The study indicates the pandemic's detrimental impact on students' mental health and quality of life. Identified risk and protective factors provide guidance for tailored prevention and treatment, as well as the design of measures for future pandemics and other crisis.

[The Structural Reform of The Psychotherapy Guidelines in Germany]

OBJECTIVES

Our study investigates how psychotherapists implement and assess the newly introduced elements of the structural reform of the psychotherapy guideline in Germany.

METHODS

We asked psychotherapists about their experiences with the structural reform in semi-structured interviews. The data was analysed using qualitative content analysis.

RESULTS

A total of 37 h of audio material from 41 psychotherapists were available. The interviews showed that acute treatment and relapse prevention are welcomed by psychotherapists. However, due to lack of appointment capacity as well as conceptual barriers, these are rarely used. Concerning psychotherapeutic assessment consultations, the opinions were heterogeneous.

CONCLUSION

Individual aspects of the new care elements are assessed positively. However, these can only be implemented to a limited extent and are not sufficient to significantly improve the strained supply situation.

Prevalence, persistence, and course of symptoms of depression, anxiety, and stress of mothers and fathers. Results of an 18-year longitudinal study

BACKGROUND

Mental health problems in mothers and fathers are common. This longitudinal study analyzed the prevalence, course, and persistence of symptoms of depression, anxiety, and stress over 18 years in parents based on a sample from the Future Family project (N = 316).

METHODS

At pre-assessment the children were on average 4.2, the mothers 35.3, and the fathers 38.1 years old. Over time, the parents repeatedly filled out the "Depression, Anxiety, Stress Scales" (DASS). Analyses included descriptive methods, Chi2-tests, binary logistic regression models, and different analytical approaches (number chains, transition probability).

RESULTS

Approximately 6.2 % of mothers and 8.2 % of fathers suffered from borderline clinical or clinically relevant depression (anxiety: 5.4 %/6.3 %, stress: 12.6 %/14.2 %). The largest proportion of the sample was stable healthy over the 18-year period (depression: 89.1 %/86.8 %; anxiety: 90.2 %/86.2 %; stress: 75.3 %/75.7 %), whereas 2.2 % of mothers and 3.9 % of fathers showed chronic symptoms of depression (anxiety: 1.8 %/3.9 %; stress: 5.1 %/9.2 %). The remaining mothers and fathers were distributed among positive, negative, and transient courses. Child's mental health problems and mother's traumatic experiences in childhood were found to be important predictors of maternal chronic symptoms of depression, anxiety, and stress. Based on the selected models, no significant prediction was found for fathers. The average short-term persistence (from one assessment to the next) was 42 % in mothers and 44 % in fathers, the average long-term persistence rates (over 18 years) were somewhat lower (35 %/38 %).

CONCLUSION

Prevention programs and psychotherapy should be considered as an effective and economic approach to reduce mothers' and fathers' psychopathology in Germany.

Three-wave longitudinal prediction of positive mental health in Germany and China

The present study is a follow-up of a prior study examining a broad range of longitudinal predictors of dimensional positive mental health (PMH) and negative mental health (NMH), using cross-cultural data from the Bochum Optimism and Mental Health (BOOM) study. The present study sought to expand prior findings on positive mental health predictors to a longer longitudinal timeframe. The analysis, specifically, tests our prior model using a third time point, The following positive constructs were examined in relation to later positive mental health: resilience, social support, social rhythm, family affluence, physical health and expectations for fertility. Negative predictors depression, anxiety, and stress were also examined in relation to time 3 positive mental health. Participants included university student samples from Germany (N = 591) and China (N = 8,831). Structural equation modeling was used to examine the effects of predictors on mental health. In China, three of the six salutogenic predictors (social rhythm regularity, positive mental health, resilience) at baseline were predictive of positive mental health at both follow-ups with generally small, but significant effects. Social support at baseline predicted more, and stress and anxiety predicted less positive mental health at follow-up 1, with generally small effects. Depression at baseline predicted less positive mental health at follow-up 2. In Germany, two of the six salutogenic predictors (positive mental health, social support) at baseline were predictive of positive mental health at both follow-ups, with generally small effects. Pathogenic predictors were not predictive of positive mental health at either follow-up. According to multi group analysis, the paths from positive mental health baseline to positive mental health follow-up 1 (FU1) as well as the path positive mental health FU1 to positive mental health follow-up 2 (FU2) were found to differ between Germany and China. All other paths could be seen as equivalent in Germany and China. Results indicate prediction of positive mental health over an extended period of time, and in particular by salutogenic predictors. Pathogenic predictors were also (negatively) predictive of PMH, but with more mixed results, underscoring the differential prediction of PMH from salutogenic and pathogenic factors.

Trajectories of quality of life, return to work, psychopathology, and disability in survivors of the acute respiratory distress syndrome (ARDS): A three-year prospective cohort study (DACAPO)

PURPOSE

Describe the long-term development of outcomes for survivors of the Acute Respiratory Distress Syndrome (ARDS).

MATERIAL AND METHODS

A cohort study with N = 877 ARDS survivors was conducted. Health related quality of life (HRQoL, Physical and Mental Component Scale: PCS, MCS of the SF-12), return to work (RtW), panic disorder, depressive symptoms (PHQD), and post-traumatic-stress-disorder (PTSD, PTSS-14) were assessed at 3, 6, 12, 24, and 36 months after discharge from ICU.

RESULTS

PCS, MCS, and RtW increased during the first 12 months [e.g. PCS: Md = 36 (IQR 31-43) at 3 months, Md = 42 (IQR 34-52) at 12 months; MCS: Md = 44 (IQR 32-54) at 3 months, Md = 47 (IQR 33-57) at 12 months, RtW = 23.2% at 3 months, 54.5% at 12 months], and remained relatively stable afterwards. Proportion of major depressive syndrome decreased from 3 (14.2%) to 36 months (8.9%). Proportions of panic disorder (5.3% to 7.4%) and PTSD (27.1% to 32.6%) varied only slightly.

CONCLUSIONS

Most of recovery in HRQoL and RtW occur during the first 12 months, after which a plateau is reached, indicating a chronification for many patients. Contrary to this, however, psychopathological symptoms remain stable, except for depressive symptoms. [200 words].

Factors influencing the duration of untreated illness among patients with anorexia nervosa: A multicenter and multi-informant study

INTRODUCTION

The duration of untreated illness (DUI), that is, the interval between the onset of anorexia nervosa (AN) symptoms and start of specialized treatments, has a strong influence on the prognosis.

OBJECTIVE

To quantify modifiable predictors of the DUI and to derive recommendations for secondary prevention strategies.

METHODS

Within a multicenter, multi-informant study, DUI was assessed in interviews with patients undergoing first specialized AN treatment. Modifiable factors were assessed perspectives of AN-patients, their relatives, and primary care practitioners [PCPs]) with the FABIANA-checklist (Facilitators and barriers in anorexia nervosa treatment initiation). The effect of FABIANA-items on the DUI for each perspective was calculated using Cox Regression (control variables: age, eating disorder pathology, health care status, migration background, body mass index [BMI]).

RESULTS

We included data from N = 125 female patients with AN (72 adults, 53 adolescents, Mage  = 19.2 years, SD = 4.2, MBMI  = 15.7 kg/m2 , SD = 1.9), N = 89 relatives (81.8% female, 18.2% male, Mage  = 46.0 years, SD = 11.0) and N = 40 PCPs (Mage  = 49.7 years, SD = 9.0). Average DUI was 12.0 months. Watching or reading articles about the successful treatment of other individuals with AN (patients' perspective) and regular appointments with a PCP (PCPs' perspective) were related to a shorter DUI (HR = 0.145, p = .046/ HR = 0.395, p = .018). Patients whose relatives rated that PCPs trivialized patients' difficulties had a longer DUI (HR = -0.147, p = .037). PCPs and relatives rated PCPs' competence higher than patients did.

DISCUSSION

It is recommended (a) to incorporate treatment success stories in prevention strategies, (b) to inform PCPs about potential benefits of regular appointments during the transition to specialized care, and (c) to train PCPs in dealing with patients' complaints.

PUBLIC SIGNIFICANCE

Many individuals with AN seek treatment very late. Our study shows that a promising approach to facilitate earlier AN treatment is to inform patients about successful treatments of affected peers, to foster regular appointments with a PCP and, to motivate these PCPs to take individuals' with AN difficulties seriously. Thus, our study provides important suggestions for interventions that aim to improve early treatment in AN.

[Psychotherapy for elderly patients]

A particular feature of the demographic change is the growing proportion of elderly and very elderly people. In Western countries, this is largely due to improved medical care for age-associated diseases. There is still comparatively little knowledge about mental health disorders in old age, their age-typical clinical presentation and specific psychotherapeutic treatment.

Adverse drug reactions in geriatric psychiatry-retrospective cohort study of a 6-year period

OBJECTIVE

To investigate the frequency and characteristics of adverse drug reactions (ADRs) that occurred on the gerontopsychiatric ward of Hannover Medical School over a 6-year period.

DESIGN

Retrospective monocentric cohort study.

RESULTS

Six hundred thirty-four patient cases (mean age 76.6 ± 7.1 years; 67.2% female) were analysed. In total, 92 ADRs in 56 patient cases were registered in the study population. The overall ADR prevalence, the ADR prevalence upon hospital admission, and the ADR prevalence during hospitalisation were 8.8%, 6.3%, and 4.9%, respectively. The most frequent ADRs were extrapyramidal symptoms, alterations in blood pressure or heart rate, and electrolyte disturbances. Of note, two cases of asystole and one case of obstructive airway symptoms related to general anaesthesia in the context of electroconvulsive therapy (ECT) were detected. The presence of coronary heart disease was associated with an increased risk of ADR occurrence (odds ratio (OR) 2.92, 95% confidence interval (CI) 1.37-6.22), while the presence of dementia was associated with a decreased risk of ADR development (OR 0.45, 95% CI 0.23-0.89).

CONCLUSIONS

Type and prevalence of ADRs in the present study were largely in accordance with previous reports. By contrast, we did not observe a relationship between advanced age or female sex and ADR occurrence. We detected a risk signal for cardiopulmonary ADRs related to general anaesthesia in the context of ECT that warrants further investigation. Elderly psychiatric patients should be carefully screened for cardiopulmonary comorbidities before initiation of ECT.

Effect of the addition of a mental health specialist for evaluation of undiagnosed patients in centres for rare diseases (ZSE-DUO): a prospective, controlled trial with a two-phase cohort design

Background

People with complex symptomatology but unclear diagnosis presenting to a centre for rare diseases (CRD) may present with mental (co-)morbidity. We hypothesised that combining an expert in somatic medicine with a mental health specialist working in tandem will improve the diagnostic outcome.

Methods

Patients aged 12 years and older who presented to one of the 11 participating German CRDs with an unknown diagnosis were recruited into this prospective cohort trial with a two-phase cohort design. From October 1, 2018 to September 30, 2019, participants were allocated to standard care (SC, N = 684), and from October 1, 2019 to January 31, 2021 to innovative care (IC, N = 695). The cohorts consisted mainly of adult participants with only a minority of children included (N = 67). IC included the involvement of a mental health specialist in all aspects of care (e.g., assessing medical records, clinic visits, telehealth care, and case conferences). Clinicaltrials.gov identifier: NCT03563677.

Findings

The proportion of patients with diagnoses established within 12 months after the first visit to the CRD explaining the entire symptomatology (primary outcome) was 19% (N = 131 of 672) in the SC and 42% (N = 286 of 686) in the IC cohort (OR adjusted for centre effects 3.45 [95% CrI: 1.99-5.65]). The difference was mainly due to a higher prevalence of mental disorders and non-rare somatic diseases in the IC cohort. The median time to explaining diagnoses was one month shorter with IC (95% CrI: 1-2), and significantly more patients could be referred to local regular care in the IC (27.5%; N = 181 of 659) compared to the SC (12.3%; N = 81 of 658) cohort (OR adjusted for centre effects 2.70 [95% CrI: 2.02-3.60]). At 12-month follow-up, patient satisfaction with care was significantly higher in the IC compared to the SC cohort, while quality of life was not different between cohorts.

Interpretation

Our findings suggested that including a mental health specialist in the entire evaluation process of CRDs for undiagnosed adolescents and adults should become an integral part of the assessment of individuals with a suspected rare disease.

Funding

The study was funded by the Global Innovation Fund from the Joint Federal Committee in Germany (Innovationsfonds des Gemeinsamen Bundesausschusses), grant number 01NVF17031.

Determinants of the intention to seek psychotherapeutic consultation at work - a cross-sectional study in Germany

BACKGROUND

Psychotherapeutic consultation at work (PT-A) provides employees with mental illnesses or subclinical symptoms a short-term and low-threshold access to psychotherapeutic care. However, practical experience shows that the utilisation rate seems low compared to expected demand. Therefore, this study aimed to identify determinants of utilisation by exploring associations between sociodemographic characteristics, psychological well-being, stigma-related barriers and psychosocial safety climate and the intention to seek PT-A.

METHODS

Within a cross-sectional study, 658 participants were recruited via various social media channels in Germany. Participants answered an online questionnaire on potential determinants of (1) intention to seek PT-A in general and of intention to seek PT-A to specifically discuss (2) occupational burden and (3) private burden. Multiple ordinal regression analyses were conducted for the whole study sample and for the subgroups of participants screened positive and negative for current depression.

RESULTS

Lower stigma-related barriers were associated with higher general intention to seek PT-A among all study groups. Lower psychological well-being was associated with higher general intention to seek PT-A and with higher intention to seek PT-A to discuss occupational and private burden, but only so in the subgroup of employees who were screened negative for current depression. Treatment experience was associated with higher intention to seek PT-A for occupational burden among participants screened negative but not among participants screened positive for current depression. No associations were found between age, gender, education or psychosocial safety climate and any variable of intention to seek PT-A.

CONCLUSION

Those results give an overview on potential determinants for the intention to seek PT-A, but future research with longitudinal designs is needed to confirm that those factors also determine actual utilisation of PT-A. Based on the results, practical implications might include antistigma campaigns and promotion of PT-A adapted to the aims of the consultation.

Fear conditioning and fear generalization in children and adolescents with anxiety disorders

Overgeneralization of conditioned fear is associated with anxiety disorders (AD). Most results stem from studies done in adult patients, but studies with children are rare, although the median onset of anxiety disorders lies already in childhood. Thus, the goal of the present study was to examine fear learning and generalization in youth participants, aged 10-17 years, with AD (n = 39) compared to healthy controls (HC) (n = 40). A discriminative fear conditioning and generalization paradigm was used. Ratings of arousal, valence, and US expectancy (the probability of an aversive noise following each stimulus) were measured, hypothesizing that children with AD compared to HC would show heightened ratings of arousal and US expectancy, and decreased positive valence ratings, respectively, as well as overgeneralization of fear. The results indicated that children with AD rated all stimuli as more arousing and less pleasant, and demonstrated higher US expectancy ratings to all stimuli when compared to HC. Thus, rather than displaying qualitatively different generalization patterns (e.g., a linear vs. quadratic slope of the gradient), differences between groups were more quantitative (similar, but parallel shifted gradient). Therefore, overgeneralization of conditioned fear does not seem to be a general marker of anxiety disorders in children and adolescents.

[Psychotherapeutic appointments given by Associations of Statutory Health Insurance Physicians in 2019 : An analysis differentiated by appointment type and region]

BACKGROUND

One provision of the Care Provision Strengthening Act in Germany was that psychotherapeutic appointments (psychotherapeutic consultation, acute care, and probatory sessions) are now arranged through the Association of Statutory Health Insurance Physicians organizations. We examined how many appointments were requested and given in 2019, differentiated by appointment type and by city state versus areal state organizations.

METHODS

The frequency of requests and appointments made in 2019 were collected from the Association of Statutory Health Insurance Physicians organizations in Germany using a questionnaire. Statistical analysis comprised descriptive evaluations and a Kruskal-Wallis test.

RESULTS

Data for appointments were available from 17 and information on requests from 16 Association of Statutory Health Insurance Physicians organizations. A total of 134,578 appointments were given. The number of granted appointments ranged from 193 to 21,810, revealing substantial differences between the individual organizations. The share of psychotherapeutic consultations among all psychotherapeutic appointments granted amounted to a median of 92%. Per organization, appointments were given for a median of 87% of requests for a psychotherapeutic consultation (range 56-100%), 96% for acute care requests (range 29-100%), and 97% for probatory session requests (range 27-100%) (n = 16, respectively). There were minor differences between city states and areal states in granting acute care and probatory sessions.

DISCUSSION

There are deficits both in city state and areal state Association of Statutory Health Insurance Physicians organizations in terms of granting acute care and probatory sessions. Our results do not allow conclusions about distance to the practices or waiting times.

Claims data analysis of the health care utilization for patients with coronary heart disease and mental comorbidity

OBJECTIVE

Mental disorders (MD) are a common comorbidity in patients with coronary heart disease (CHD) and have a significant impact on morbidity and mortality. The aim of this study was to determine to what extent mental disorders are diagnosed as comorbidity in patients with CHD and whether adequate therapeutic measures are taken.

METHODS

Claims data from 4435 Cologne citizens with diagnosed CHD and a hospital stay due to CHD in 2015 were examined through a longitudinal analysis. The data were analyzed descriptively with regard to mental disorders, investigating diagnostic examinations performed, prescriptions for psychotropic drugs, and utilization of psychotherapy. We differentiated between pre-existing MD, existing in the year before the CHD-related hospital stay, and incident MD with new onset during or within six months after hospitalization.

RESULTS

Psychodiagnostic examinations for mental disorders occurred very rarely during cardiological hospitalization (0.04%) and psychiatric/psychosomatic consultation sessions rarely (5%). The longitudinal analysis showed a high rate of pre-existing MDs (56%, n = 2490) and a new diagnosis of mental disorders in 7% (n = 302) of the patients. Within one year after inpatient treatment for CHD, psychotropic medication was prescribed in 64-67% of patients with newly diagnosed affective or neurotic, adjustment/somatoform disorder and 10-13% received outpatient psychotherapy.

CONCLUSION

The results indicate low rates of inpatient diagnostic examinations and low rates of adequate treatment of mental disorders in patients from Cologne with CHD and new onset mental disorders. The rate of prescriptions of psychopharmacotherapy after hospitalization due to CHD exceeds that of the utilization of outpatient psychotherapy.

Selective breeding of rats for high (HAB) and low (LAB) anxiety-related behaviour: A unique model for comorbid depression and social dysfunctions

Animal models of selective breeding for extremes in emotionality are a strong experimental approach to model psychopathologies. They became indispensable in order to increase our understanding of neurobiological, genetic, epigenetic, hormonal, and environmental mechanisms contributing to anxiety disorders and their association with depressive symptoms or social deficits. In the present review, we extensively discuss Wistar rats selectively bred for high (HAB) and low (LAB) anxiety-related behaviour on the elevated plus-maze. After 30 years of breeding, we can confirm the prominent differences between HAB and LAB rats in trait anxiety, which are accompanied by consistent differences in depressive-like, social and cognitive behaviours. We can further confirm a single nucleotide polymorphism in the vasopressin promotor of HAB rats causative for neuropeptide overexpression, and show that low (or high) anxiety and fear levels are unlikely due to visual dysfunctions. Thus, HAB and LAB rats continue to exist as a reliable tool to study the multiple facets underlying the pathology of high trait anxiety and its comorbidity with depression-like behaviour and social dysfunctions.

Urbanization and mental health: A perspective from Riyadh City, Kingdom of Saudi Arabia

BACKGROUND

While global studies demonstrated that features of urban living are associated with the risk of developing mental disorders, there remains a significant knowledge gap surrounding this topic in the Middle East and North Africa region.

AIMS

This study aims to assess the prevalence, severity, correlates, and treatment of mental disorders in Riyadh City by examining certain aspects of urban living such as exposure to traumatic events, early exposure to urbanization, and seeking treatment.

METHODS

The Saudi National Mental Health Survey is a community epidemiological survey in a nationally representative sample of citizens aged 15 to 65 in KSA. The World Health Organization Composite International Diagnostic Interview (CIDI 3·0) was used to estimate the 12-month prevalence of common mental disorders.

RESULTS

The prevalence of any mental disorder in Riyadh City was 29.2%. The most common disorders were anxiety disorders and mood disorders. Female, young, and previously married respondents were at higher risk for developing mental disorders. Exposure to traumatic events was associated with all types of mental disorders. Only 2.9% of those with any mental disorder sought mental health treatments.

CONCLUSIONS

We found a high prevalence of mental disorders in Riyadh City that could be attributed to certain features of urban living. These results may point to potential interventions in urban areas that can mitigate the adverse consequences of urban living and promote the salutogenic aspects of cities.

Anticipated fear and anxiety of Automated Driving Systems: Estimating the prevalence in a national representative survey

Background

Automated Driving Systems (ADS) may reshape mobility. Yet, related fear and anxiety are largely unknown. We estimated the prevalence and risk factors of anticipated anxiety towards ADS.

Method

In a nationally representative face-to-face household survey, we assessed anticipated levels of anxiety towards ADS based on DSM-5 specific phobia criteria, using structured diagnostic interviews. We estimated weighted prevalences and conducted adjusted logistic regression models.

Results

Of N = 2076 respondents, 40.82% (95%-confidence interval (CI) 37.73-43.98) anticipated experiencing some symptoms of phobia of ADS, 15.22% (CI 13.19-17.51) anticipated subthreshold phobia, and 3.39% (CI 2.42-4.75) anticipated full-blown phobia of ADS. Of subjects anticipating subthreshold phobia, 74.02% showed no strong, enduring fears of driving non-automated cars and 65.07% presented no other specific phobias (full-blown anticipated phobia: 50.37% and 50.03%, respectively). Anticipated phobia highly overlapped with anticipating marked or strong fears of passively encountering ADS in traffic (odds ratio 312.4-1982.2).

Conclusion

About 20% of subjects anticipated at least subthreshold and 4% of subjects anticipated full-blown phobia of ADS. It appears to be distinct from fears related to non-automated driving and other specific phobias. Our findings call for prevention and treatment of phobia of ADS as they become increasingly ubiquitous.

Ecological momentary assessment and applied relaxation: Results of a randomized indicated preventive trial in individuals at increased risk for mental disorders

Applied Relaxation (AR) is an established behavioral mental health intervention, but its efficacy in real life contexts remains unclear. Using randomized controlled trial data, we examined whether AR can effectively reduce mental health problems in daily life. A sample of 277 adults with increased psychopathological symptoms but without 12-month DSM-5 mental disorders at study entry was randomly assigned to an intervention group receiving AR training (n = 139) and an assessment-only control group (n = 138). Ecological momentary assessments were used to assess psychological outcomes in daily life over a period of seven days at baseline, post, and 12-month follow-up, respectively. Multilevel analyses indicated that all psychopathological symptoms decreased more in the intervention group than in the control group from baseline to post (range β = -0.31 for DASS-depression to β = -0.06 for PROMIS-anger). However, from post to follow-up, psychopathological symptoms decreased more in the control group than in the intervention group, so that only the intervention effects for PROMIS-depression (β = -0.10) and PROMIS-anger (β = -0.09) remained until follow-up. Moreover, positive affect (β = 0.19), internal control beliefs (β = 0.15), favorable coping (β = 0.60), and unfavorable coping (β = -0.41) improved more in the intervention group than in the control group, and these effects were mostly maintained in the long term. Some effects were stronger among women, older individuals, and individuals with higher initial symptoms. These findings suggest that AR can effectively reduce mental health problems in daily life.

The somatic care of patients with comorbid mental disorders: protocol of a mixed-methods study aiming to identify barriers to and enablers of utilization of somatic healthcare (SoKo)

BACKGROUND

Healthcare for people with somatic and comorbid mental diseases can pose a challenge to the healthcare system. The aim of the SoKo study (the Somatic care of patients with mental Comorbidity) is to assess the current state of care and the facilitators and barriers of somatic care of people with somatic disorders and comorbidity of a mental disorder.

METHODS

The study is conducted as a mixed-methods approach and will include (a) descriptive and inferential analysis of secondary claims data of persons insured by a German statutory health insurance company in North Rhine-Westphalia (Techniker Krankenkasse, TK-NRW), (b) qualitative individual interviews and group discussions, and (c) based on (a) and (b), quantitative surveys of both patients and physicians. We intend to analyse a sample of claims data of about 2.6 million persons insured by TK-NRW (group comparisons between TK-NRW insured persons with a diagnosis of a prevalent somatic disease [ICD-10-GM E01-E07, E11, E66, I10-I15, I20-I25, I60-I64] with and without comorbidity of a mental disorder [F00-F99]), in order to assess the uptake of somatic care by people with mental and somatic comorbidity. In addition, primary data from patients with the aforementioned somatic illnesses and a mental comorbidity as well as primary data from physicians (general practitioners and medical specialists) will be collected. The focus here will be on support factors and barriers in the somatic care of people with mental comorbidity.

DISCUSSION

Up to now, there have been no published results of a systematic collection of both secondary and primary data on the utilisation of different care services of somatically ill patients with mental comorbidity for Germany. The present mixed-methods study aims to address this gap.

TRIAL REGISTRATION

The trial is registered with the German Clinical Trials Register DRKS: DRKS00030513. The trial was registered on 3rd February 2023.

Mood and anxiety disorders within the Research Domain Criteria framework of Positive and Negative Valence Systems: a scoping review

Introduction

While a growing body of research is adopting Research Domain Criteria (RDoC)-related methods and constructs, there is still a lack of comprehensive reviews on the state of published research on Positive Valence Systems (PVS) and Negative Valence Systems (NVS) in mood and anxiety disorders consistent with the RDoC framework.

Methods

Five electronic databases were searched to identify peer-reviewed publications covering research on "positive valence" and "negative valence" as well as "valence," "affect," and "emotion" for individuals with symptoms of mood and anxiety disorders. Data was extracted with a focus on disorder, domain, (sub-) constructs, units of analysis, key results, and study design. Findings are presented along four sections, distinguishing between primary articles and reviews each for PVS, NVS, and cross-domain PVS and NVS.

Results

A total of 231 abstracts were identified, and 43 met the inclusion criteria for this scoping review. Seventeen publications addressed research on PVS, seventeen on NVS, and nine covered cross-domain research on PVS and NVS. Psychological constructs were typically examined across different units of analysis, with the majority of publications incorporating two or more measures. Molecular, genetic, and physiological aspects were mainly investigated via review articles, primary articles focused on self-report, behavioral, and, to a lesser extent, physiological measures.

Conclusions

This present scoping review shows that mood and anxiety disorders were actively studied using a range of genetic, molecular, neuronal, physiological, behavioral, and self-report measures within the RDoC PVS and NVS. Results highlight the essential role of specific cortical frontal brain structures and of subcortical limbic structures in impaired emotional processing in mood and anxiety disorders. Findings also indicate overall limited research on NVS in bipolar disorders and PVS in anxiety disorders, a majority of self-report studies, and predominantly observational studies. Future research is needed to develop more RDoC-consistent advancements and intervention studies targeting neuroscience-driven PVS and NVS constructs.

The influence of perceived stress and income on mental health in China and Germany

Background

Mental health issues affect rich and poor, young and old, and are widespread in Asia as well as in Europe. However, few studies have investigated the influence of perceived stress and income on mental health among general population in China and in Germany.

Methods

We conducted an online survey from December 2021 to February 2022 to investigate how perceived stress and income affect mental health among the general population in China (N = 1123) and in Germany (N = 1018). Accordingly, we used the 10-item Perceived Stress Scale (PSS-10) and the 12-item General Health Questionnaire (GHQ-12). We ran a multiple linear regression model to investigate the relationship between perceived stress, income, and mental health.

Results

Overall, we found that 53.4% participants reported mental health issues (GHQ-12 score ≥12). The proportion of our sample who reported mental health issues was higher in Germany (60.3%) than in China (44.8%). The regression model revealed that a higher perceived stress score was associated with more mental health issues in both countries (b = 0.60, p < 0.01). Individuals with a low income reported poorer mental health in Germany than those in China. Interestingly, the situation was reversed when incomes were high: individuals with a high income reported worse mental health in China than in Germany (b = -0.40, p < 0.01).

Conclusion

Perceived stress has a negative impact on mental health, while income has differential effects. Mental health promotion programmes may involve teaching stress management, while considering differences in mental health outcomes in developed and developing countries.

Heterogeneous Mental Health Responses to the COVID-19 Pandemic in Germany: An Examination of Long-Term Trajectories, Risk Factors, and Vulnerable Groups

Abundant studies have examined mental health in the early periods of the COVID-19 pandemic. However, empirical work examining the mental health impact of the pandemic's subsequent phases remains limited. In the present study, we investigated how mental vulnerability and resilience evolved over the various phases of the pandemic in 2020 and 2021 in Germany. Data were collected (n = 3522) across seven measurement occasions using validated and self-generated measures of vulnerability and resilience. We found evidence for an immediate increase in vulnerability during the first lockdown in Germany, a trend towards recovery when lockdown measures were eased, and an increase in vulnerability with each passing month of the second lockdown. Four different latent trajectories of resilience-vulnerability emerged, with the majority of participants displaying a rather resilient trajectory, but nearly 30% of the sample fell into the more vulnerable groups. Females, younger individuals, those with a history of psychiatric disorders, lower income groups, and those with high trait vulnerability and low trait social belonging were more likely to exhibit trajectories associated with poorer mental well-being. Our findings indicate that resilience-vulnerability responses in Germany during the COVID-19 pandemic may have been more complex than previously thought, identifying risk groups that could benefit from greater support.

Mental health of people with limited access to health services: a retrospective study of patients attending a humanitarian clinic network in Germany in 2021

BACKGROUND

Germany has a statutory health insurance system. However, a substantial part of the population still suffers from limited access to regular health services. While humanitarian organizations are partially filling this gap, people with limited access show a high prevalence of mental disorders. This study investigates the prevalence, and social determinants of mental disorders in patients attending the clinics of a humanitarian health network in three major cities in Germany, as well as perceived barriers to healthcare access in this population.

METHODS

We performed a descriptive, retrospective study of individuals attending the outpatient clinics of the humanitarian organization Ärzte der Welt, in Berlin, Hamburg and Munich, in 2021. Medico-administrative data was collected using a digital questionnaire at first presentation to the clinics. We report the prevalence of both perceived altered mental health and diagnosed mental disorders, as well as the perceived barriers to healthcare access in this population. We performed a logistic regression analysis to identify the socio-demographic factors associated with mental disorders.

RESULTS

Our study population consisted of 1,071 first presenters to the clinics in 2021. The median age at presentation was 32 years and 57.2% of the population were male. 81.8% experienced a form of homelessness, 40% originated from non-EU countries and only 12.4% had regular statutory health insurance. 101 (9.4%) patients had a diagnosed mental disorder. In addition, 128 (11.9%) patients reported feeling depressed, 99 (9.2%) reported a lack of interest in daily activities, and 134 (12.5%) lacked emotional support in situations of need on most days. The most reported barrier to accessing health services was high health expenses, reported by 61.3% of patients.In the bivariate logistic regression analysis age, insurance status and region of origin were significantly associated with mental disorders. In the multivariable analysis, only age groups 20-39 and 40-59 years remained significant.

CONCLUSIONS

People with limited access to regular health services have a high need for mental health services. As a chronic condition, this is even more difficult to manage outside of regular services, where humanitarian clinics are only filling the gap in serving basic health needs.

Employees' preferences on organisational aspects of psychotherapeutic consultation at work by occupational area, company size, requirement levels and supervisor function - a cross-sectional study in Germany

BACKGROUND

Common mental disorders affect a significant proportion of the population worldwide at any given time. Psychotherapeutic consultation at work offers employees with mental distress short-term and low-threshold access to psychotherapeutic treatment. However, this offer is only accepted by one to two percent of the employees to whom it is offered. Taking into account employees ' preferences regarding organisational aspects might increase the use of psychotherapeutic consultation at work. This study therefore aimed to identify preferences on organisational aspects of psychotherapeutic consultation at work among employees of diverse occupational areas, company sizes, supervisor functions and job requirement levels.

METHODS

A total of 755 employees were recruited via advertisements on social media (Instagram, Facebook and LinkedIn). Participants rated on a 5-point Likert scale their agreement to different implementation options of psychotherapeutic consultation at work: type (in-person/video/telephone), location (on/outside company premises), time (within/outside working hours), scope (diagnostic/diagnostic + treatment) and purpose (private/occupational). Additionally, the maximum accepted distance to the location of consultation was assessed. Various analyses of variances (ANOVA) were conducted to determine differences in agreement to implementation options within each organisational aspect and to analyse differences between occupational areas, company sizes, requirement levels and between employees with and without supervisor function.

RESULTS

Participants indicated a preference for in-person psychotherapeutic consultation that takes places outside company premises and outside working hours. Furthermore, they preferred offers including diagnostic and treatment sessions compared to offers including diagnostic sessions only. Even though participants agreed that consultation should be offered for all purposes, agreement for occupational issues was stronger than for private issues. For some implementation options, the level of agreement varied according to occupational field, company size, supervisor function and level of requirement. However, these differences did not affect the key findings mentioned above.

CONCLUSION

Those findings give practical indications on the organisational design of psychotherapeutic consultation at work. The results suggest that in-person consultation outside company premises and working hours combining diagnostic and treatment sessions will be accepted by employees regardless of their occupational area, company size, supervisor function and requirement level.

Depression Is Associated with an Increased Risk of Subsequent Cancer Diagnosis: A Retrospective Cohort Study with 235,404 Patients

Background: Depression and cancer share common risk factors and mechanisms of disease. The current literature has not explored the effect of depression on cancer risk. We assessed the difference in cancer risk in patients with and without depression in a large cohort in Germany. Methods: We compared cancer risk and incidence in patients with and without depression aged 18 or above diagnosed between 2015 and 2018 documented in the Disease Analyzer Database. Patients from a comparator group were matched 1:1 to patients with depression based on propensity scores. Patients with previous bipolar disorder (F31), mania (F30) or schizophrenia (F20-29) and cancer diagnosis 3 years prior to index date were excluded. Analyses were stratified by cancer type, age group, and gender. Results: A total of 117,702 patients with depression were included and matched 1:1, resulting in a cohort overall of 235,404. 4.9% of patients with depression compared to 4.1% without depression received at least one cancer diagnosis over 3.9 years median follow-up. The depression group showed an 18% increase in risk for a cancer diagnosis overall, with largest increased risk in lung cancer (HR: 1.39 [1.21-1.60], p < 0.0001), cancers of the gastro-intestinal-tract (HR: 1.30 [1.15-1.46], p < 0.0001), breast (HR: 1.23 [1.12-1.35], p < 0.0001) and urinary (HR: 1.23 [1.06-1.43], p < 0.01). Similarly, the incidence of cancer diagnosis overall increased by 22% for depressed patients. IRs showed no difference across cancer types. Conclusions: Depression increased the risk for cancer diagnosis consistently independent of the comparison method used. The potential mediating factors or shared mechanisms of the disease require further investigation.

Unipolare Depression – psychodynamische Vielfalt

Versorgungsengpässe in der ambulanten Psychotherapie haben in den letzten Jahren zu diversen Gesetzesinitiativen geführt. Eine davon war die Einführung von diagnosespezifischen Behandlungskontingenten. Ausgehend von diesem gesundheitspolitischen Vorhaben fragten wir uns, inwiefern empirische Daten für oder gegen eine solche Praxis sprechen, das heißt, wie „homogen“ Patient:innen mit derselben ICD-10-Diagnose aus psychodynamischer Sicht sind. Mithilfe der qualitativen Inhaltsanalyse wurden 13 Berichte von Patient:innen mit der Erstdiagnose F33.1 (Rezidivierende depressive Störung, gegenwärtig mittelgradige Episode) ausgewertet, die im Rahmen des Gutachtenverfahrens geprüft wurden. Zusätzlich schätzten wir das generelle Funktionsniveau ein und verglichen die Reife der Abwehr mit dem Vorliegen komorbider psychischer Diagnosen. Es wurden 56 Seiten Textmaterial analysiert. Wir identifizierten 4 Konflikttypen (Selbstwert, Nähe-Distanz, Unterwerfung, Schuld) sowie strukturelle Beeinträchtigungen in 4 Bereichen (Selbst- und Objektwahrnehmung, Selbstregulierung, Bindung und Identität), bei Vorliegen verschiedener Therapieziele und Interaktionsformen. Die Abwehr bewegte sich auf unreifem bis neurotischen Niveau, was nicht im Zusammenhang mit dem Vorliegen komorbider Diagnosen stand. Das Funktionsniveau ließ auf ein breites Spektrum genereller Beeinträchtigung schließen. Unsere Ergebnisse legen nahe, dass Depressionen vielfältige psychodynamische Hintergründe haben. Dies steht im Widerspruch zu der Idee einer Zuordnung von ICD-10-Diagnose und Behandlungskontingent.

Tinnitus and Its Relation to Depression, Anxiety, and Stress-A Population-Based Cohort Study

Tinnitus is a common symptom reported in otolaryngologic practice. Although the pathophysiology of tinnitus has not been fully understood, clinical studies suggest that psychological symptoms of depression, anxiety, and somatization are increased in tinnitus patients. However, patients seeking medical treatment for tinnitus may be especially vulnerable. Population-based studies reporting on the association between tinnitus and psychological distress are still lacking. The aim of this study was to investigate the correlation of tinnitus with depression, anxiety, or somatization in a large population-based cohort. The Gutenberg Health Study is a population-based cohort study. Participants were asked about the occurrence of tinnitus (yes/no) and how much they were bothered by it. In addition, they completed the PHQ-9, GAD-7, and SSS-8 questionnaires to assess depressive symptoms, anxiety, and somatic symptom disorders. A total of 8539 participants were included in the study cohort. Tinnitus prevalence was 28.0% (2387). The prevalence of depression/anxiety/somatic symptom disorders was significantly higher among participants with tinnitus than among participants without tinnitus (7.9%/5.4%/40.4% participants with tinnitus vs. 4.6%/3.3%/26.9% participants without tinnitus, p-value < 0.0001). Logistic regression results showed that participants with tinnitus were more likely to suffer from depression (OR = 2.033, 95% CI [1.584; 2.601], p-value < 0.0001), anxiety (OR = 1.841, 95% CI [1.228; 2.728], p-value = 0.0027), or somatic symptom disorders (OR = 2.057, 95% CI [1.799; 2.352], p-value < 0.0001). Symptoms of depression, anxiety, and somatic symptom disorders were increased in participants with tinnitus. This must be taken into account when treating these patients.

Self-regulation profiles reflecting distinct levels of eating disorder and comorbid psychopathology in the adult population: A latent profile analysis

OBJECTIVE

Previous research showed that individuals with eating disorders (EDs) can be subtyped by their levels of psychopathology and self-regulation abilities. However, nothing is known about whether self-regulation abilities are solely suited to depict the heterogeneity in ED and comorbid psychopathology in nonclinical samples. Therefore, this study sought to explore self-regulation profiles and their ability to discriminate ED, depression and anxiety disorders, and personality dysfunction in the adult population.

METHODS

Within a German representative sample, N = 2391 adults (18-92 years) were examined using latent profile analysis to identify profiles based on established cognitive and emotional self-regulation scales including attention control, cognitive reappraisal, and difficulties in identifying feelings. Profiles were validated with ED, depression, anxiety, and personality dysfunction measures.

RESULTS

The final solution selected as best balancing goodness of fit and interpretability included four profiles-High-Functioning, Moderate-Functioning, Dysregulated, and Alexithymic-with high explanatory power of R²  = .99. Profiles were characterized primarily by differences in difficulties in identifying feelings followed by differences in attention control and differed significantly regarding ED, depression and anxiety disorders, and personality dysfunction, with the Dysregulated profile showing the most unfavorable correlates.

CONCLUSIONS

This study uniquely revealed that low cognitive and emotional self-regulation were indicators for ED, depression, anxiety, and personality dysfunction in the adult population. Future research should investigate whether the identified profiles predict the development of ED and comorbid psychopathology longitudinally.

PUBLIC SIGNIFICANCE

Individuals with eating disorders present with difficulties in cognitive and emotional self-regulation, likely maintaining their symptoms. This representative study in the German adult population sought to build profiles based on cognitive and emotional self-regulation that differed in eating disorder and comorbid psychopathology. We discuss the potential to detect individuals with elevated eating disorder and comorbid psychopathology based on the identified profiles in nonclinical settings.

Supporting return to work after psychiatric hospitalization-A cluster randomized study (RETURN-study)

BACKGROUND

If people with episodic mental-health conditions lose their job due to an episode of their mental illness, they often experience personal negative consequences. Therefore, reintegration after sick leave is critical to avoid unfavorable courses of disease, longer inability to work, long payment of sickness benefits, and unemployment. Existing return-to-work (RTW) programs have mainly focused on "common mental disorders" and often used very elaborate and costly interventions without yielding convincing effects. It was the aim of the RETURN study to evaluate an easy-to-implement RTW intervention specifically addressing persons with mental illnesses being so severe that they require inpatient treatment.

METHODS

The RETURN study was a multi-center, cluster-randomized controlled trial in acute psychiatric wards addressing inpatients suffering from a psychiatric disorder. In intervention wards, case managers (RTW experts) were introduced who supported patients in their RTW process, while in control wards treatment, as usual, was continued.

RESULTS

A total of 268 patients were recruited for the trial. Patients in the intervention group had more often returned to their workplace at 6 and 12 months, which was also mirrored in more days at work. These group differences were statistically significant at 6 months. However, for the main outcome (days at work at 12 months), differences were no longer statistically significant (p = 0.14). Intervention patients returned to their workplace earlier than patients in the control group (p = 0.040).

CONCLUSIONS

The RETURN intervention has shown the potential of case-management interventions when addressing RTW. Further analyses, especially the qualitative ones, may help to better understand limitations and potential areas for improvement.

Economic expectations and anxiety during the COVID-19 pandemic: a one-year longitudinal evaluation on Italian university students

The COVID-19 pandemic has produced an extensive aggravation of people's anxiety level. Different policies aimed at fighting the spread of the virus could affect anxiety in various ways. We built an ad hoc web-based survey, administered to the student population of three Italian universities at the beginning of the pandemic and at one year's distance, to collect information on retrospective and current anxiety levels and the underlining reasons. The survey also included questions concerning sociodemographic, economic, labor, lifestyle, academic career, and on-line teaching features, which prevents students from identifying the main survey topic to be anxiety. This research aims at assessing the change in anxiety levels between the analyzed periods and the main determinants of such change, focusing on students' economic expectancies. Results from a Poisson regression model show that anxiety has increased compared to both the pre-pandemic level and the one quantified during the first lockdown. This increase is revealed to be mostly driven by economic and career-related uncertainties, rather than by job loss and proximity to COVID-19. Thus, policymakers should take action to provide certainties both in terms of economic prospects and reopening strategies, especially to avoid that the resulting increase in anxiety translates into an amplified suicide risk.

[Psychiatry, Crises and Policies]

From the perspective of global societal crises, this paper discusses the long-term socio-political withdrawal of psychiatry into a self-defined position of therapy- and rehabilitation-oriented medicine with no responsibility for social, economic or political conditions. Global crises suggest mental health and overall resilience of the population as key societal resources. Only mental health and psychosocial resilience of people and societies worldwide will determine whether our answers to the current and future existential threats will be effective. This challenge requires a radical change of attitudes of both society and psychiatry. The rich expertise of psychiatry, e. g. on on how to balance autonomy and compulsion or regarding the interdependencies of cognition and human behaviour must contribute significantly to the socio-political debate and the fight against undesirable social or political developments.

Anxiety and cognitive functioning in the Maastricht study: A cross-sectional population study

BACKGROUND

Higher anxiety levels in older adults are associated with worse executive functioning and an increased risk for dementia. In this study individual anxiety disorders and clinically relevant generalized anxiety symptoms are studied in relation to multiple cognitive domains.

METHOD

This cross-sectional study includes 7344 community-dwelling participants of The Maastricht Study aged 40-75 years and oversampling of type 2 diabetes. Panic disorder with and without agoraphobia, agoraphobia and lifetime panic disorder were measured with the Mini International Neuropsychiatric Interview. Generalized anxiety symptoms were measured with the Generalized Anxiety Disorder 7-item scale (GAD-7). Multiple cognitive domains (executive functioning, memory and processing speed) and cognitive impairment were assessed. Multivariable linear and logistic regression analyses were used with adjustment for potential confounders. Interaction analyses were performed to test the moderation of age, sex and type 2 diabetes (due to oversampling).

RESULTS

Agoraphobia was associated with worse scores on all cognitive domains (range B = -0.12 to -0.10; range 95%CI = -0.20 to -0.04) and with higher odds of cognitive impairment (OR = 1.51, 95%CI = 1.18-1.93). High scores on the GAD-7 were associated with worse scores on processing speed (B = -0.11, 95%CI = -0.20 to -0.03) and higher odds of cognitive impairment (OR = 1.42, 95%CI = 1.02-1.97). Panic disorder was significantly associated with worse scores on memory tasks (B = -0.25, 95%CI = -0.48 to -0.02). Associations were stronger in the younger participants and for agoraphobia and GAD-7 scores also in those with type 2 diabetes.

CONCLUSION

Multiple anxiety disorders and generalized anxiety symptoms were associated with worse cognitive functioning on several cognitive domains.

[Associations of Internal Migration and Somatoform Symptoms, Depression, and Anxiety in a German Representative Sample]

AIM

The aim of the present study was to determine, if internal German migration was associated with mental distress, somatoform symptoms, depression, and anxiety.

METHODS

Data from two representative studies from 2020 and 2021 were analysed (N=4922). Mental distress, including the dimensions somatoform symptoms, depression, and anxiety, was assessed with the short version of the Brief Symptom Inventory (BSI-18). Linear regression analyses were performed to examine associations between internal migration and mental distress while controlling for sociodemographic factors (gender, age, partner, household equivalised income, and education).

RESULTS

Internal migrants from East to West Germany reported more mental distress, somatoform symptoms, depression, and anxiety than those who grew up and stayed in the East. This finding remained after controlling for sociodemographic factors. No differences were found between internal migrants from West to East Germany and those who grew up and stayed in West Germany.

DISCUSSION

German internal migration should be taken into account when examining differences in mental health in East and West Germany. Our results suggest that particularly the group that had moved from the Eastern to the Western part of Germany reported significantly signs of mental distress.

[Posttraumatic Disorders and Their Impact on the Capacity to Work]

Posttraumatic Disorders and Their Impact on the Capacity to Work Abstract. Posttraumatic disorders include a range of mental illnesses and can have relevant effects on the capacity to work. Work usually is an important resource in treatment. The severity or type of trauma is not decisive for assessing the capacity to work, but the functional limitations caused by the disorder must be carefully assessed and compared with the requirements of the job. The rating by Mini-ICF-APP is a helpful tool for this. A reintegration-oriented attitude can strongly support the treatment.

Examining bidirectional associations between perceived social support and psychological symptoms in the context of stressful event exposure: a prospective, longitudinal study

BACKGROUND

After stressful event exposure, higher perceived social support is a well-established correlate of decreased risk for psychological symptoms, including depressive, anxiety and posttraumatic stress (PTS) symptoms. However, longitudinal data on the direction of this association and the stability of perceived social support are scarce and have yielded mixed results, with a particular lack of prospective studies. We aimed to investigate changes in perceived social support and bidirectional associations between perceived social support and psychological symptoms in a prospective, longitudinal study.

METHODS

A sample of German soldiers was assessed before and after deployment to Afghanistan. Group-based trajectory modelling was used to investigate the stability of perceived social support and to identify possible distinguishable trajectories of perceived social support. Bidirectional associations between perceived social support (general and workplace) and psychological symptoms (depressive, anxiety and PTS) were examined using gamma regressions.

RESULTS

Average levels of perceived general social support did not change, while perceived workplace social support increased slightly (t(344) = 5.51, p < .001). There were no distinguishable trajectories of perceived social support. Higher perceived general (Mean ratio (MR) = 0.84, 95% CI = [0.74, 0.95]) and workplace social support (MR = 0.82, 95% CI = [0.72, 0.92]) predicted lower depressive symptoms, but not anxiety or PTS symptoms. Only higher PTS (MR = 0.95, 95% CI = [0.91, 0.99]) and higher depressive symptoms (MR = 0.96, 95% CI = [0.93, 0.99]) predicted lower perceived general social support.

CONCLUSIONS

Perceived social support can remain relatively stable under exposure to environmental stressors such as military deployment. Higher perceived social support could protect against depressive symptoms via a stress-buffering mechanism, while support may need to be more tailored to individual needs for a protection against PTS symptoms. Individuals with elevated depressive and PTS symptoms might have impaired abilities or opportunities to access social support after stressful event exposure. Future studies could investigate distressing social emotions and associated maladaptive social cognitions as possible mechanisms in the association between symptoms and lower perceived social support. Especially with respect to PTS symptoms, future studies could focus on conditions that enable individuals to benefit from social support.

Personalised depression forecasting using mobile sensor data and ecological momentary assessment

INTRODUCTION

Digital health interventions are an effective way to treat depression, but it is still largely unclear how patients' individual symptoms evolve dynamically during such treatments. Data-driven forecasts of depressive symptoms would allow to greatly improve the personalisation of treatments. In current forecasting approaches, models are often trained on an entire population, resulting in a general model that works overall, but does not translate well to each individual in clinically heterogeneous, real-world populations. Model fairness across patient subgroups is also frequently overlooked. Personalised models tailored to the individual patient may therefore be promising.

METHODS

We investigate different personalisation strategies using transfer learning, subgroup models, as well as subject-dependent standardisation on a newly-collected, longitudinal dataset of depression patients undergoing treatment with a digital intervention ( N = 65 patients recruited). Both passive mobile sensor data as well as ecological momentary assessments were available for modelling. We evaluated the models' ability to predict symptoms of depression (Patient Health Questionnaire-2; PHQ-2) at the end of each day, and to forecast symptoms of the next day.

RESULTS

In our experiments, we achieve a best mean-absolute-error (MAE) of 0.801 (25% improvement) for predicting PHQ-2 values at the end of the day with subject-dependent standardisation compared to a non-personalised baseline ( MAE = 1.062 ). For one day ahead-forecasting, we can improve the baseline of 1.539 by 12 % to a MAE of 1.349 using a transfer learning approach with shared common layers. In addition, personalisation leads to fairer models at group-level.

DISCUSSION

Our results suggest that personalisation using subject-dependent standardisation and transfer learning can improve predictions and forecasts, respectively, of depressive symptoms in participants of a digital depression intervention. We discuss technical and clinical limitations of this approach, avenues for future investigations, and how personalised machine learning architectures may be implemented to improve existing digital interventions for depression.

Combining the GP's assessment and the PHQ-9 questionnaire leads to more reliable and clinically relevant diagnoses in primary care

Background

Screening questionnaires are not sufficient to improve diagnostic quality of depression in primary care. The additional consideration of the general practitioner’s (GP’s) assessment could improve the accuracy of depression diagnosis. The aim of this study was to examine whether the GP rating supports a reliable depression diagnosis indicated by the PHQ-9 over a period of three months.

Methods

We performed a secondary data analysis from a previous study. PHQ-9 scores of primary care patients were collected at the time of recruitment (t1) and during a follow-up 3 months later (t2). At t1 GPs independently made a subjective assessment whether they considered the patient depressive (yes/no). Two corresponding groups with concordant and discordant PHQ-9 and GP ratings at t1 were defined. Reliability of the PHQ-9 results at t1 and t2 was assessed within these groups and within the entire sample by Cohen’s Kappa, Pearson’s correlation coefficient and Bland-Altman plots.

Results

364 consecutive patients from 12 practices in the region of Upper Bavaria/Germany participated in this longitudinal study. 279 patients (76.6%) sent back the questionnaire at t2. Concordance of GP rating and PHQ-9 at t1 led to higher replicability of PHQ-9 results between t1 and t2. The reliability of PHQ-9 was higher in the concordant subgroup (κ = 0.507) compared to the discordant subgroup (κ = 0.211) (p = 0.064). The Bland-Altman Plot showed that the deviation of PHQ-9 scores at t1 and t2 decreased by about 15% in the concordant subgroup. Pearson’s correlation coefficient between PHQ-9 scores at t1 and t2 increased significantly if the GP rating was concordant with the PHQ-9 at t1 (r = 0.671) compared to the discordant subgroup (r = 0.462) (p = 0.044).

Conclusions

The combination of PHQ-9 and GP rating might improve diagnostic decision making regarding depression in general practices. PHQ-9 positive results might be more reliable and accurate, when a concordant GP rating is considered.

Störungsspezifische und transdiagnostische Veränderung der Inflammationsaktivität bei psychischen Störungen

Zusammenfassung. Theoretischer Hintergrund: Empirische Befunde deuten vermehrt auf eine erhöhte Entzündungsaktivität im Zusammenhang mit psychischen Störungen hin. Inwieweit sich inflammatorische Veränderungen über Störungen hinweg unterscheiden bzw. ob Inflammation ein transdiagnostisches Korrelat psychischer Störungen darstellt, ist bisher jedoch noch nicht eindeutig beantwortet. Fragestellung: Liegen spezifische inflammatorische Marker (z. B. Zytokine) über psychische Störungen hinweg verändert vor und/oder gibt es störungsspezifische Zytokinveränderungen bei Major Depression (MDD), Bipolarer Störung, Schizophrenie und Angststörungen inkl. Posttraumatischer Belastungsstörung (PTBS). Methode: Basierend auf einer Literaturrecherche werden aktuelle metaanalytische Befunde, die Studien bei Patient_innen mit MDD, Bipolarer Störung, Schizophrenie oder Angststörungen inkl. PTBS im Vergleich zu gesunden Kontrollen betrachten, zusammengetragen und vergleichend dargestellt. Ergebnisse: Aktuelle Evidenz verweist relativ konsistent auf Veränderungen des Immunsystems, wobei v. a. das Zytokin Interleukin (IL–) 6 und das C-reaktive Protein (CRP) störungsübergreifend leicht erhöht sind. Schlussfolgerungen: Perspektivisch könnten Patient_innen mit chronisch inflammatorischen Erkrankungen und psychischen Störungen von psychotherapiebegleitenden antiinflammatorischen Maßnahmen wie bspw. körperlicher Aktivität, antiinflammatorischer Ernährung und Entspannungsverfahren profitieren.

Die soziale Angststörung – ein Update

Es kann passieren, dass man sich vermeintlich peinlich oder insuffizient verhält; kurzfristige Gefühle wie Scham oder Selbstzweifel bleiben meist jedoch ohne Bedeutung. Kommt es aber zu überzogenen und überdauernden Befürchtungen oder signifikantem Vermeidungsverhalten, kann es sich um eine soziale Angststörung (SAS) handeln. Der vorliegende Artikel bietet eine Übersicht über den aktuellen Stand der Ätiologie, Diagnostik und Therapie der SAS.

Increasing the effectiveness of psychotherapy in routine care through blended therapy with transdiagnostic online modules (PsyTOM): study protocol for a randomized controlled trial

BACKGROUND

In blended therapy, face-to-face psychotherapy and Internet-based interventions are combined. Blended therapy may be advantageous for patients and psychotherapists. However, most blended interventions focus on cognitive behavioral therapy or single disorders, making them less suitable for routine care settings.

METHODS

In a randomized controlled trial, we will compare blended therapy and face-to-face therapy in routine care. We intend to randomize 1152 patients nested in 231 psychotherapists in a 1:1 ratio. Patients in the blended therapy group will receive access to a therapeutic online intervention (TONI). TONI contains 12 transdiagnostic online modules suited for psychodynamic, cognitive behavioral, and systemic therapy. Psychotherapists decide which modules to assign and how to integrate TONI components into the psychotherapeutic process to tailor treatment to their patients' specific needs. We will assess patients at baseline, 6 weeks, 12 weeks, and 6 months. Patients enrolled early in the trial will also complete assessments at 12 months. The primary outcomes are depression and anxiety at 6-month post-randomization, as measured by PHQ-8 and GAD-7. The secondary outcomes include satisfaction with life, level of functioning, personality traits and functioning, eating pathology, sexual problems, alcohol/drug use, satisfaction with treatment, negative effects, and mental health care utilization. In addition, we will collect several potential moderators and mediators, including therapeutic alliance, agency, and self-efficacy. Psychotherapists will also report on changes in symptom severity and therapeutic alliance. Qualitative interviews with psychotherapists and patients will shed light on the barriers and benefits of the blended intervention. Furthermore, we will assess significant others of enrolled patients in a sub-study.

DISCUSSION

The integration of online modules which use a common therapeutic language and address therapeutic principles shared across therapeutic approaches into regular psychotherapy has the potential to improve the effectiveness of psychotherapy and transfer it into everyday life as well help save therapists' resources and close treatment gaps. A modular and transdiagnostic setup of the blended intervention also enables psychotherapists to tailor their treatment optimally to the needs of their patients.
