RESUMO

Adaptive coding of reward is the process by which neurons adapt their response to the context of available compensations. Higher rewards lead to a stronger brain response, but the increase of the response depends on the range of available rewards. A steeper increase is observed in a narrow range and a more gradual slope in a wider range. In schizophrenia, adaptive coding appears to be affected in different domains, especially in the reward domain. Here, we tested adaptive coding of reward in a large group of patients with schizophrenia (n = 86) and control subjects (n = 66). We assessed: (i) the association between adaptive coding deficits and symptoms; (ii) the longitudinal stability of deficits (the same task was performed 3 months apart); and (iii) the stability of results between two experimental sites. We used functional MRI and the monetary incentive delay task to assess adaptation of participants to two different reward ranges: a narrow range and a wide range. We used a region-of-interest analysis to evaluate adaptation within striatal and visual regions. Patients and control subjects underwent a full demographic and clinical assessment. We found reduced adaptive coding in patients, with a decreased slope in the narrow reward range with respect to that of control participants, in striatal but not visual regions. This pattern was observed at both research sites. Upon retesting, patients increased their narrow-range slopes, showing improved adaptive coding, whereas control subjects slightly reduced them. At retesting, patients with overly steep slopes in the narrow range also showed higher levels of negative symptoms. Our data confirm deficits in reward adaptation in schizophrenia and reveal an effect of practice in patients, leading to improvement, with steeper slopes upon retesting. However, in some patients, an excessively steep slope may result in poor discriminability of larger rewards, owing to early saturation of the brain response. Together, the loss of precision of reward representation in new (first exposure, underadaptation) and more familiar (retest, overadaptation) situations might contribute to the multiple motivational symptoms in schizophrenia.

RESUMO

INTRODUCTION: There is a significant demand for interventions that reduce distress related to auditory verbal hallucinations (AVHs). AVH distress is associated with the way voice hearers relate with AVHs. We aimed to establish the feasibility of a randomized controlled trial to demonstrate that adding "Relating Therapy" (RT) to treatment as usual (TAU) is superior to TAU in reducing AVH distress. METHODS: We conducted a multicenter, parallel, single-blind, randomized controlled feasibility trial in five mental health centers in Germany. Participants were ≥19 years of age, had persistent and distressing AVHs, and had a diagnosis of a schizophrenia-spectrum disorder. RT was delivered over a maximum of 16 sessions within 5 months. Blind assessments were conducted at baseline and at 5 and 9 months. Feasibility outcomes were the number of patients recruited and retained, and safety and therapist adherence. The primary endpoint was the distress factor score of the AVH subscale of the Psychotic Symptoms Rating Scales at 9 months. RESULTS: Eighty-five of 177 enrolled participants were randomized into RT + TAU (n = 43) or TAU (n = 42). Feasibility was excellent with 87% retention at 9 months, 86% reaching treatment uptake criteria, 98% therapist adherence, and no unexpected serious adverse reactions. Compared to TAU, RT + TAU showed nonsignificant trends toward less AVH distress (b = -2.40, SE = 1.52, p = 0.121, 90% CI (-4.94 to 0.15) and stronger improvement on all but one of the secondary outcomes. CONCLUSION: A randomized controlled trial of RT is feasible, safe, and well accepted. Our results provide an encouraging basis to further test the efficacy of RT in a definitive multicenter trial.

RESUMO

Adolescent refugees and asylum seekers (ARAS) are highly vulnerable to mental health problems. Stepped care models (SCM) and culturally sensitive therapies offer promising treatment approaches to effectively provide necessary medical and psychological support. To our knowledge, we were the first to investigate whether a culturally sensitive SCM will reduce symptoms of depression and PTSD in ARAS more effectively and efficiently than treatment as usual (TAU). We conducted a multicentric, randomized, controlled and rater-blinded trial across Germany with ARAS between the ages of 14 to 21 years. Participants (N = 158) were stratified by their level of depressive symptom severity and then equally randomized to either SCM or TAU. Depending on their severity level, SCM participants were allocated to tailored interventions. Symptom changes were assessed for depression (PHQ) and PTSD (CATS) at four time points, with the primary end point at post-intervention after 12 weeks. Based on an intention-to-treat sample, we used a linear mixed model approach for the main statistical analyses. Further evaluations included cost-utility analyses, sensitivity analyses, follow-up-analyses, response and remission rates and subgroup analysis. We found a significant reduction of PHQ (d = 0.52) and CATS (d = 0.27) scores in both groups. However, there was no significant difference between SCM and TAU. Cost-utility analyses indicated that SCM generated greater cost-utility when measured as quality-adjusted life years compared to TAU. Subgroup analysis revealed different effects for the SCM interventions depending on the outcome measure. Although culturally sensitive, SCMs did not prove to be more effective in symptom change and represent a more cost-effective treatment alternative for mentally burdened ARAS. Our research contributes to the optimization of clinical productivity and the improvement of therapeutic care for ARAS. Disorder-specific interventions should be further investigated.

RESUMO

BACKGROUND: Providing adequate living conditions for forcibly displaced people represents a significant challenge for host countries such as Germany. This study explores refugee mental health's reciprocal, dynamic relationship with post-migration living conditions and social support. METHODS: The study sample included 325 Arabic- or Farsi-speaking asylum seekers and refugees residing in Germany since 2014 and seeking mental health treatment. Associations between reported symptoms of post-traumatic stress and depression and the subjective quality of living conditions and perceived social support were analyzed using a two-level approach including multiple linear regression and network analyses. RESULTS: Post-migration quality of living conditions and perceived social support were significantly associated with negative mental health outcomes on both levels. In the network, both post-migration factors were negatively connected with overlapping symptoms of psychiatric disorders, representing potential target symptoms for psychological treatment. CONCLUSION: Post-migration quality of living conditions and social support are important factors for refugee mental health and should be targeted by various actors fostering mental well-being and integration.

RESUMO

Mindfulness-based therapies are increasingly available for a range of mental disorders, such as depression and anxiety. However, there remain concerns that mindfulness has the potential to exacerbate psychosis, despite a growing body of literature demonstrating effectiveness. These concerns may relate to long-standing perceptions about the suitability of offering psychological therapies to people with psychosis.

RESUMO

OBJECTIVE: Numerous studies support the effectiveness of acceptance and commitment therapy (ACT) for chronic pain, yet little research has been conducted about its underlying mechanisms of change, especially regarding patients with comorbid mental disorders. The present investigation addressed this issue by examining associations of processes targeted by ACT (pain acceptance, mindfulness, psychological flexibility) and clinical outcomes (pain intensity, somatic symptoms, physical health, mental health, depression, general anxiety). SUBJECTS: Participants were 109 patients who attended an ACT-based interdisciplinary treatment program for chronic pain and comorbid mental disorders in a routine care psychiatric day hospital. METHODS: Pre- to posttreatment differences in processes and outcomes were examined with Wilcoxon signed-rank tests and effect size r. Associations between changes in processes and changes in outcomes were analyzed with correlation and multiple regression analyses. RESULTS: Pre- to posttreatment effect sizes were mostly moderate to large (r between 0.21 and 0.62). Associations between changes in processes and changes in outcomes were moderate to large for both, bivariate correlations (r between 0.30 and 0.54) and shared variances accounting for all three processes combined (R2 between 0.21 and 0.29). CONCLUSION: The present investigation suggests that changes in pain acceptance, mindfulness, and psychological flexibility are meaningfully associated with changes in clinical outcomes. It provides evidence on particular process-outcome associations that had not been investigated in this way before. The focus on comorbid mental disorders informs clinicians about a population of chronic pain patients who often have a severe course of illness and have seldom been studied.

RESUMO

The sudden arrival of culturally diverse asylum seekers and refugees into Germany has created a strong demand for recognizing and appropriately treating those suffering from mental health issues. Due to many systemic, organizational, cultural and socio-linguistic barriers, psychiatric treatment of refugees is posing a major challenge to Germany's mental health care system. Thus, there is a need for alternative models that allow for increased access to adequate, effective and efficient culturally sensitive mental health care services. Here, we describe the Mental Health in Refugees and Asylum Seekers (MEHIRA) project, a multicentre randomized controlled trial investigating a stepped collaborative care model (SCCM) for providing mental health treatment in this vulnerable population. The proposed SCCM aims to decrease the aforementioned barriers. Adult and adolescent participants will be screened for depressive symptoms and matched to appropriate psychological interventions, including group-level interventions (START intervention, Empowerment/Gender-sensitive/Peer to peer), and other innovative, digital treatment approaches (Smartphone application). The therapeutic effect of the SCCM will be compared to TAU (treatment-as-usual). All interventions have been designed to be culturally sensitive, and offered in two different languages: Arabic and Farsi. The outcome of this study may contribute significantly to future clinical and legal guidelines in developing parallel and efficient new structures of treatment. Collected data will inform primary and secondary mental health care providers with recommendations concerning the design and implementation of effective treatment models and programmes. Guidelines and recommendations may also potentially be adopted by other host countries, developing countries and also in humanitarian aid programmes.

RESUMO

OBJECTIVE: In light of the current humanitarian crises in the Arabic world, a version of the Mini International Neuropsychiatric Interview (MINI) in standard Arabic, enabling a fast and efficient diagnosis of psychiatric disorders, is urgently needed. The aim of the present pilot study was to provide a culturally sensitive translation and adaptation of the MINI to standard Arabic and to undertake first steps towards its validation in a sample of Arab refugees. METHODS: Various experts in the field of psychiatry and psychotherapy, familiar with both Western and Arab cultures, were involved in the multi-level adaption process. N = 20 Arabic speaking refugee patients could be recruited for the pilot study at the Clearingstelle, established by the Charité, Univeritätsmedizin Berlin. The MINI diagnoses were compared to diagnoses by experts who were blinded to the MINI diagnoses, and screening instruments for depression (Patient Health Questionnaire 9, PHQ-9) and posttraumatic stress disorder (PTSD) (Harvard Trauma Questionnaire, HTQ) were used. RESULTS: Details concerning the particularities of the cultural adaptation process are comprehensively summarized and presented. Kappa values did not show any satisfactory concordance between the MINI and expert diagnoses. However, significantly strong concordance was found between the MINI and the PHQ-9 (κ = .69) and the HTQ (κ = .68). CONCLUSION: These results provide first indications for the validity of the standard Arabic version of the MINI and can be used as a basis for further, more comprehensive validation studies. Moreover, this study depicts a model process for the cultural adaptation of psychometric instruments.

RESUMO

Many people with schizophrenia spectrum disorders (SSDs) experience profound amotivation, which is strongly related to anticipatory anhedonia. Yet, the neuropsychological fundamentals of anticipatory anhedonia and amotivation are barely understood, resulting in a lack of effective treatments for these patients. Aberrancies in positive mental imagery may interfere with the anticipation of pleasure and could thus explain anticipatory anhedonia and amotivation. However, the nature of mental imagery and its relationship with amotivational psychopathology in SSD is largely unknown. In this preregistered study, we therefore examined mental imagery characteristics and their relation to anticipatory anhedonia, amotivation, and daily life activity in SSD. TheN = 86 participants included individuals with SSD (n = 43) and demographically matched healthy controls (n = 43). Mental imagery, anticipatory pleasure, amotivation, and activity engagement were assessed with structured interviews and self-report questionnaires. Ecological momentary assessment was used to measure state anticipatory pleasure and activity engagement in daily life (n = 81). Compared to the control group, the SSD group showed comparable quantity, but less vividness of mental imagery. Reduced vividness of mental imagery in SSD was significantly associated with higher anticipatory anhedonia, amotivation, and low activity engagement in cross-sectional and prospective analyses. Reduced mental imagery vividness may cause a lack of internal incentive to seek pleasurable experiences and could explain amotivation. Interventions aiming to improve mental imagery vividness and related anticipatory pleasure responses in SSD may be effective in targeting amotivation.

RESUMO

BACKGROUND: In recent years, a growing body of evidence has demonstrated the efficacy of non-pharmacological interventions for schizophrenia spectrum disorders (SSD) including positive symptoms such as auditory hallucinations (AH). However, clinical trials predominantly examine general treatment effects for positive symptoms. Therefore, previous research is lacking in comprehensive and clear evidence about psychological and psychosocial approaches that are primarily tailored to treat AH. To overcome this knowledge gap in the current literature, we will conduct a systematic review and meta-analysis to assess the efficacy of clearly targeted psychological and psychosocial interventions for AH in persons with SSD. METHODS AND ANALYSIS: This study protocol has been developed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. We will include all randomized controlled trials analyzing the efficacy of targeted psychological and psychosocial interventions especially aimed at treating AH in SSD. We will include studies on adult patients with SSD experiencing AH. The primary outcome will be the change on a published rating scale measuring AH. Secondary outcomes will be delusions, overall symptoms, negative symptoms, depression, social functioning, quality of life, and acceptability (drop-out). We will search relevant databases and the reference lists of included literature. The study selection process will be conducted by two independent reviewers. We will conduct a random-effect meta-analysis to consider heterogeneity across studies. Analyses will be carried out by software packages in R. The risk of bias in each study will be evaluated using the Cochrane Risk of Bias tool. Assessment of heterogeneity and sensitivity analysis will be conducted. DISCUSSION: The proposed study will augment the existing evidence by providing an overview of effective treatment approaches and their overall efficacy at treating AH in SSD. These findings will complement existing evidence that may impact future treatment implementations in clinical practice by addressing effective strategies to treat AH and therefore improve outcomes for the addressed population. ETHICS AND DISSEMINATION: No ethical issues are foreseen. We will publish the results from this study in peer-reviewed journals and at relevant scientific conferences. TRIAL REGISTRATION: PROSPERO registration number: CRD42023475704.

RESUMO

BACKGROUND: Negative symptoms in schizophrenia (SZ), such as apathy and diminished expression, have limited treatments and significantly impact daily life. Our study focuses on the functional division of the striatum: limbic-motivation and reward, associative-cognition, and sensorimotor-sensory and motor processing, aiming to identify potential biomarkers for negative symptoms. STUDY DESIGN: This longitudinal, 2-center resting-state-fMRI (rsfMRI) study examines striatal seeds-to-whole-brain functional connectivity. We examined connectivity aberrations in patients with schizophrenia (PwSZ), focusing on stable group differences across 2-time points using intra-class-correlation and associated these with negative symptoms and measures of cognition. Additionally, in PwSZ, we used negative symptoms to predict striatal connectivity aberrations at the baseline and used the striatal aberration to predict symptoms 9 months later. STUDY RESULTS: A total of 143 participants (77 PwSZ, 66 controls) from 2 centers (Berlin/Geneva) participated. We found sensorimotor-striatum and associative-striatum hypoconnectivity. We identified 4 stable hypoconnectivity findings over 3 months, revealing striatal-fronto-parietal-cerebellar hypoconnectivity in PwSZ. From those findings, we found hypoconnectivity in the bilateral associative striatum with the bilateral paracingulate-gyrus and the anterior cingulate cortex in PwSZ. Additionally, hypoconnectivity between the associative striatum and the superior frontal gyrus was associated with lower cognition scores in PwSZ, and weaker sensorimotor striatum connectivity with the superior parietal lobule correlated negatively with diminished expression and could predict symptom severity 9 months later. CONCLUSIONS: Importantly, patterns of weaker sensorimotor striatum and superior parietal lobule connectivity fulfilled the biomarker criteria: clinical significance, reflecting underlying pathophysiology, and stability across time and centers.

RESUMO

BACKGROUND: Mindfulness-based interventions (MBIs) have emerged as secular practices, including elements of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT). While MBIs have been widely adopted for physical and mental illness, only a few available programs are explicitly adapted for psychosis. However, previous reviews have reported the vital heterogeneity regarding treatment program structure. Therefore, this review aims to compare the structure of different mindfulness protocols applied to patients with schizophrenia spectrum disorder (SSD). METHODS: A systematic search was conducted up to March 2023 in PubMed, Embase and PsycInfo. Following our protocol (CRD 42023253356), we followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist. RESULTS: We included 22 randomized controlled trials (RCTs) involving 1500 patients SSD. All programs varied in structure, session components, duration, and instructor experience. While MBSR-like programs focused on stress reactivity, MBCT-like programs addressed primary symptoms of psychosis and relapse prevention. Despite the heterogeneity of programs, some common mechanisms emerged, including attention training, emotion and stress regulation, decentering, self-compassion, and cognitive restructuring. CONCLUSIONS: The critical heterogeneity found limits the interpretation of results. However, most recent trials present fewer risks of bias and more homogenous programs. Findings suggested potential benefits, such as reduced negative symptoms, increased well-being, and decreased hospitalization rates. For future studies, authors should align on more congruent MBIs programs for patients with SSD. Further research is needed to identify optimal mindfulness teaching approaches for patients with psychosis and investigate specific mechanisms of action, relevant processes, and optimal doses in varying settings.

RESUMO

BACKGROUND: Germany has increased its political and financial commitment for global health, but this needs to be backed by a robust global health research ecosystem with strong partnerships in low- and middle-income countries (LMICs). OBJECTIVE: This article suggests pathways for empowering researchers to operate beyond their disciplinary silos and strengthen partnerships across sectors and countries. The authors identify barriers and enablers of operations from a nascent research network in Germany, trusting that this experience can inform other initiatives seeking to stoke interdisciplinary and collaborative global health research. METHODS: This article represents the culmination of extensive reflections spanning the initial four years of the German Alliance for Global Health Research (GLOHRA). The insights have additionally been informed by an analysis of publicly available reports, internal procedural records, and externally conducted studies based on interviews with researchers and policymakers. RESULTS: GLOHRA has developed a toolbox of practices that foster interdisciplinary research and support capacity-building. Insights indicate that highly interdisciplinary and diverse governance structures and seed-funding for interdisciplinary and cross-sector research with appropriate review processes represent a critical step for achieving these aims. Additionally, inclusive training sessions and networking events help to bridge disciplinary boundaries, equipping researchers to envision the broader context of their work. CONCLUSIONS: Despite achievements, challenges persist. Wider support, especially from universities and research institutions, is necessary to make global health research an attractive career path and to reduce bureaucratic barriers for collaborators in LMICs. Sustained, longer-term federal funding mechanisms will also be essential for ongoing progress.


Main findings: Germany's increased commitment to global health includes federal support for initiatives such as the nascent German Alliance for Global Health Research, a 1000+ member network which aims to foster interdisciplinary and collaborative global health research.Added knowledge: This article reveals the structures, funding mechanisms, and capacity-building initiatives that have bolstered progress on network aims.Global health impact for policy and action: Challenges persist and there is a need for sustained federal funding and wider institutional support for global health careers as well as improved conditions to support more equitable research endeavors with partners in low- and middle-income countries.

RESUMO

Background: The present study explored the feasibility and acceptability as well as the impact of mindfulness-based group therapy (MBGT) on oxytocin levels (OXT) and clinical parameters in outpatients with schizophrenia spectrum disorders (SSD). Methods: In a randomized-controlled design, outpatients with SSD (N = 48) were assigned to either MBGT in addition to German university-level treatment as usual (MBGT+TAU; n = 25) or TAU (n = 23). At baseline and at four-week post-intervention, clinical parameters and OXT levels were determined. Results: Results indicate high feasibility and acceptance with a 95.7% adherence- and 94% retention- rate of MBGT in SSD. While no significant changes in empathy were observed, MBGT+TAU demonstrated a significant reduction in positive symptoms (Positive and Negative Syndrom Scale) compared to TAU at post-intervention. OXT levels were significantly increased in MBGT+TAU at post-intervention, suggesting a potential link between mindfulness and the oxytocinergic system in SSD. Additionally, improvements in various clinical parameters were indicated. Conclusion: The study contributes to the growing evidence supporting feasibility, acceptability, and positive effects of MBGT in outpatients with SSD, emphasizing the need for further research to solidify these findings. Overall, this work sheds first evidence on the intersection of mindfulness, oxytocin, and clinical outcomes in SSD.

RESUMO

Treatment options for social cognition and negative symptoms in schizophrenia spectrum disorders (SSD) remain limited. Oxytocin could be a promising augmentation approach, but the social context influences the effect in humans. This pilot study hypothesized that oxytocin in a positive social setting through mindfulness-based group therapy (MBGT) would positively affect empathy and negative symptoms as well as affect and stress in an exploratory approach in SSD. An experimental, randomized, double-blinded (participants, psychotherapists), placebo-controlled pilot study with 41 individuals with SSD was conducted at the Charité - Universitätsmedizin Berlin. Oxytocin or placebo (24 I.U.) was administered intranasally 45 min before two sessions of MBGT each. A 2 × 2 mixed model ANCOVA design was calculated to assess empathy by the Interpersonal Reactivity Index and the Multifaceted Empathy Test and negative symptoms by the Self-Evaluation of Negative Symptoms. No benefit of oxytocin compared to placebo on empathy was observed, but significant between-group differences favoring oxytocin were found regarding the negative symptoms Diminished emotional range and Avolition. Negative affect and stress were significantly reduced compared to baseline. Mindfulness increased in both groups. Results indicated protocol adherence and retention rate of 91.1%, a drop-out rate of 8.9 % and a completion of 96 % of all sessions by the participants. No severe adverse events or side effects were reported. Our findings indicate proof-of-concept and suggest a potential role of oxytocin on negative symptoms and related variables in SSD in combination with MBGT. Future research should examine the stability of these effects with larger sample sizes.

RESUMO

Digital Mental Health Technologies (DMHTs) have the potential to close treatment gaps in settings where mental healthcare is scarce or even inaccessible. For this, DMHTs need to be affordable, evidence-based, justice-oriented, user-friendly, and embedded in a functioning digital infrastructure. This viewpoint discusses areas crucial for future developments of DMHTs. Drawing back on interdisciplinary scholarship, questions of health equity, consumer-, patient- and developer-oriented legislation, and requirements for successful implementation of technologies across the globe are discussed. Economic considerations and policy implications complement these aspects. We discuss the need for cultural adaptation specific to the context of use and point to several benefits as well as pitfalls of DMHTs for research and healthcare provision. Nonetheless, to circumvent technology-driven solutionism, the development and implementation of DMHTs require a holistic, multi-sectoral, and participatory approach.

RESUMO

This study aimed to determine the influence of psychiatric training and hands-on learning with individuals with mental illness on increasing medical students' benevolent attitudes towards psychiatry and psychiatric patients. The cross-sectional study compares medical students' attitudes before and after a compulsory psychiatry curriculum and psychiatric bedside training at Hanoi Medical University with those of non-medical students who have yet to undergo similar training. Two validated scales regarding the attitudes toward psychiatry and psychiatric patients were evaluated. Analysis of the Medical Conditions Regard Scale[1] revealed a significant difference, indicating that medical students displayed more accepting and benevolent attitudes towards psychiatry and psychiatric patients after completing the curriculum and bedside training than medical students before participation. Most stigmatising and rejecting attitudes were found among non-medical students. This study is the first to examine medical students' attitudes toward psychiatry and psychiatric patients compared to non-medical students in Vietnam. It can guide the development of the medical curriculum to increase benevolence towards psychiatric patients and interest in the psychiatric field of work in Vietnam and Southeast Asia, aiming to improve the mental health care sector.

RESUMO

The precise nature of the relationship between mindfulness, psychological flexibility (PF) and psychopathology in schizophrenia spectrum disorders (SSD) remains largely unclear and warrants further investigation. We recruited 43 persons with SSD and 43 controls. Our findings revealed that SSD showed lower mindfulness and PF than controls. Mindfulness was associated with higher PS, anticipatory pleasure, behavioral activation, and lower depressive and negative symptoms. PS was associated with lower depressive and negative symptoms and higher anticipatory pleasure and behavioral activation. The outcomes imply that targeting mindfulness and PF may prove beneficial in alleviating the amotivational psychopathology exhibited in SSD.

RESUMO

Background: Research exploring the effects of yoga therapy (YT) on individuals with schizophrenia spectrum disorders (SSD) is scarce. Therefore, the current study aimed to explore possible mechanisms of actions and processes, as well as adverse effects of a novel yoga-based group intervention (YoGI) for in-patients with SSD in a German university hospital setting. Material and methods: A longitudinal qualitative study was integrated into a rater-blinded randomized controlled trial, exploring the impact of a 4-week YoGI as add-on treatment. In-depth interviews were conducted with participants receiving YoGI (n = 19) in addition to treatment as usual (TAU) and a control group (n = 14) which only received TAU. Interviews were conducted at baseline (n = 33) and 4 weeks post-intervention (N = 28) to assess the participant's experiences and how they changed over time. The interviews (N = 61) were audio-taped, translated, coded, and analyzed by means of inductive thematic analysis. Separate case summaries were prepared for each participant to analyze longitudinal changes within subjects. The research team members collaboratively discussed the final list of themes and subcodes. Rater-based questionnaires, such as the Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), and Personal and Social Performance Scale (PSP) were administered at baseline to assess clinical outcomes. Results: At baseline, participants reported a desire to improve their stress- and symptom management. A minority of participants expressed reservations toward yoga, and several psychosocial barriers were named, including worries about symptom exacerbation. At post-intervention, four mechanisms of change became evident from the interviews: (1) acquiring competence in relaxation, (2) increased interoceptive awareness, (3) feeling connected, and (4) a sense of spiritual wellbeing. A small number of participants reported difficulties with YoGI. Conclusion: Generally, YoGI positively influenced participants' experiences of their inpatient stay, regarding distress, self- and body awareness, social connectedness, and spiritual wellbeing. However, participants also illuminated necessary adjustments to improve the intervention. YoGI will therefore be adapted and further developed in an iterative process based on a participant involvement approach. The efficacy regarding outcomes and processes needs to be investigated in a future larger-scaled randomized controlled trial.

RESUMO

BACKGROUND: Worldwide migration represents a major challenge of the 21st century. Despite the strong association between acculturation and mental health, research findings on underlining mechanisms remain inconsistent. Prior research urges to investigate sample characteristics in a more structured manner. AIMS: The purpose of this study was to systematically investigate factors impacting acculturation and depressive symptoms in a large, not exclusively clinical, sample of Vietnamese migrants in Germany. METHOD: This study investigated, with multiple regressions, factors (age at arrival, gender, education, religiousness, language skills, residence status, economic status, occupational status, migration motivation, duration of stay, and depressive symptoms) impacting the two dimensions of acculturation, dominant society immersion (DSI) and ethnic society immersion (ESI), in a not exclusively clinical sample (n = 582) of first-generation Vietnamese migrants in Germany. Further, this study examined the relationship between depressive symptoms, DSI and ESI with correlations and acculturation strategies with an ANOVA. RESULTS: Integration (72.5%) was the most common acculturation strategy, followed by separation (26.8%). In contrast, assimilation (0.5%) and marginalization (0.2%) were very rare acculturation strategies. As predictive factors for DSI lower depressive symptoms scores, male gender, higher education, and better German language skills were found significant. For ESI, less German language skills and older age at arrival were found to be significant. Higher ESI and DSI were correlated to lower depressive symptom scores. Compared to the three other acculturation strategies, integration was linked to the lowest depressive symptoms scores. CONCLUSIONS: The current study identified crucial factors in the acculturation process, such as depressive symptoms, language skills, education, gender, and age at arrival. Our findings emphasize that immersion into both the dominant and the ethnic culture plays an essential supportive role in the mental health of migrants.
