Abstract: Differentiating between various types of positive affect (PA), such as excitement, relaxation, safeness, and contentment, is important when assessing mental health. However, validated instruments measuring these types of PA are scarce, and in a Swedish context, they are nonexisting. Thus, the present study assesses the psychometric properties of the translated Swedish version of the Types of PA Scale (TPAS) using a sample of 440 Swedish adults. Corroborating previous research, confirmatory factor analyses supported a modified three-factor model (Activated PA, Relaxed PA, Safe/Content PA), showing good reliability, good convergent validity, and satisfactory discriminant validity of the factors. Furthermore, the TPAS demonstrates measurement invariance across demographics (age, gender, and education) and exhibits satisfactory construct validity by distinguishing between PA, NA and State–Trait Anxiety. Hence, the Swedish TPAS is a valid tool for measuring types of PA in the adult population of Sweden, with potential areas for improvement being discussed.

Abstract Childhood maltreatment (CM) is thought to be associated with altered responses to social stimuli and interpersonal signals. However, limited evidence exists that CM is linked to larger comfortable interpersonal distance (CID) – the physical distance humans prefer towards others during social interactions. However, no previous study has investigated this association in a comprehensive sample, yielding sufficient statistical power. Moreover, preliminary findings are limited to the European region. Finally, it is unclear how CM affects CID towards different interaction partners, and whether CID is linked to social functioning and attachment. To address these outstanding issues, adults (N = 2986) from diverse cultures and socio-economic strata completed a reaction time task measuring CID towards an approaching stranger and friend. Higher CM was linked to a larger CID towards both friends and strangers. Moreover, insecure attachment and less social support were associated with larger CID. These findings demonstrate for the first time that CM affects CID across countries and cultures, highlighting the robustness of this association.

Background: Perceived social support is an established predictor of post-traumatic stress disorder (PTSD) after exposure to a traumatic event. Gender is an important factor that could differentiate responses to social support, yet this has been little explored. Symptoms of complex PTSD are also common following trauma but have been under-researched in this context. Large scale studies with culturally diverse samples are particularly lacking.Objectives: In a multi-country sample, we examined: (a) gender differences in perceived social support and both posttraumatic stress symptom severity (PTSS) and complex posttraumatic stress symptom severity (CPTSS); (b) associations between social support and PTSS/CPTSS; and (c) the potential moderating role of gender in the relationship between perceived social support and trauma-related distress.Method: A total of 2483 adults (Mage = 30yrs, 69.9% females) from 39 countries, who had been exposed to mixed trauma types, completed the Multidimensional Scale of Perceived Social Support and the International Trauma Questionnaire (which captures PTSS/CPTSS). Regression analyses examined associations between gender, perceived social support, and PTSS/CPTSS; and tested for gender by social support interactions in predicting PTSS/CPTSS scores. Models were adjusted for age and socioeconomic status.Results: In our cross-country sample, females had greater PTSS/CPTSS than males (B = .23 [95% CI 0.16, 0.30], p

Abstract: The intimacy questionnaire by Birnie (2009; Birnie-Porter & Lydon, 2013) is a promising measure of relationship intimacy due to its strong theoretical background, the inclusion of lay conceptions and the differentiation of emotional and sexual intimacy. This study aimed to validate our German translation of Birnie’s questionnaire, which we labeled Intimacy Scale (IS). In two independent samples (379 and 203 individuals), confirmatory factor analyses showed best support for a bifactor S-1 model, with a strong general intimacy factor and a small specific factor, capturing unique portions of the variance related to sexual intimacy. The general intimacy factor correlated very highly and to the point of redundancy with relationship quality. Taken together, the IS may be useful as measure of relationship quality with a general (intimacy) factor. Future research is needed to improve the factorial structure of the scale.

(1) Background: Various cutaneous adverse drug reactions (ADRs) are observed with the implementation of mRNA COVID-19 vaccines. To gain insight into the clinicopathologic features, we analyzed the correlation of histological and clinical data in 48 patients with these ADRs. (2) Methods: Single-center retrospective study in patients with ADRs after mRNA COVID-19 vaccination (mRNA-1273 and BNT162b2 vaccines). (3) Results: Distant generalized ADRs prevailed (91%), often appearing clinically as spongiotic dermatitis or maculopapular exanthema. Histopathological analysis revealed spongiotic changes (46%) and dermal superficial perivascular predominantly lymphocytic infiltrates (17%). Eosinophils were found in 66% of biopsies, neutrophils in 29%, and plasma cells only in 8% of biopsies. Most ADRs occurred after the second vaccine dose (44%). Histologically spongiotic changes were associated with clinical features of spongiotic dermatitis in only 50% of patients and maculopapular exanthema in the remaining patients. ADRs represented an aggravation of preexisting skin disease in 23% of patients. ADRs regressed within 28 days or less in 53% of patients and persisted beyond a month in the remaining patients. (4) Conclusions: Our study demonstrates a diverse spectrum of generalized ADRs, revealing correlations between histology and clinical features but also instances of divergence. Interestingly, in about half of our patients, ADRs were self-limited, whereas ADRs extended beyond a month in the other half.

Abstract Background Emotional reactivity is an important construct to consider when studying mental disorders. This study was conducted to translate and assess the factor structure, construct validity and internal consistency of a German version of the Emotion Reactivity Scale (ERS), which is an originally English questionnaire assessing three components of emotional reactivity: sensitivity, intensity and persistence of emotions. Methods The German ERS and a range of questionnaires used to assess convergent and discriminant validity were completed by 334 German speaking Swiss participants. Results Confirmatory factor analysis showed strong support for a bi-factor model, with evaluation indices pointing to a unidimensional construct rather than to domain specific factors. The questionnaire showed good reliability and the factor structure was similar across gender. The ERS showed convergent validity with general psychopathology, behavioral inhibition, negative affect, orienting sensitivity, depressive symptoms and symptoms of disordered eating, and discriminant validity with behavioral activation and alcohol consumption. Conclusions Findings support the construct validity of the German ERS and suggest that it assesses a unidimensional construct with high internal consistency. Accounting for the unidimensional nature of the scale and aiming for efficient assessment tools, future research could, based on these findings, develop and evaluate the psychometric properties of a short version of the ERS.

Abstract Background Individuals with a history of child maltreatment (CM) are more often disliked, rejected and victimized compared to individuals without such experiences. However, contributing factors for these negative evaluations are so far unknown. Objective Based on previous research on adults with borderline personality disorder (BPD), this preregistered study assessed whether negative evaluations of adults with CM experiences, in comparison to unexposed controls, are mediated by more negative and less positive facial affect display. Additionally, it was explored whether level of depression, severity of CM, social anxiety, social support, and rejection sensitivity have an influence on ratings. Methods Forty adults with CM experiences (CM +) and 40 non-maltreated (CM-) adults were filmed for measurement of affect display and rated in likeability, trustworthiness, and cooperativeness by 100 independent raters after zero-acquaintance (no interaction) and 17 raters after first-acquaintance (short conversation). Results The CM + and the CM- group were neither evaluated significantly different, nor showed significant differences in affect display. Contrasting previous research, higher levels of BPD symptoms predicted higher likeability ratings (p = .046), while complex post-traumatic stress disorder symptoms had no influence on ratings. Conclusions The non-significant effects could be attributed to an insufficient number of participants, as our sample size allowed us to detect effects with medium effect sizes (f2 = .16 for evaluation; f2 = .17 for affect display) with a power of .95. Moreover, aspects such as the presence of mental disorders (e.g., BPD or post-traumatic stress disorder), might have a stronger impact than CM per se. Future research should thus further explore conditions (e.g., presence of specific mental disorders) under which individuals with CM are affected by negative evaluations as well as factors that contribute to negative evaluations and problems in social relationships.

Background: Individuals with child maltreatment (CM) experiences show alterations in emotion recognition (ER). However, previous research has mainly focused on populations with specific mental disorders, which makes it unclear whether alterations in the recognition of facial expressions are related to CM, to the presence of mental disorders or to the combination of CM and mental disorders, and on ER of emotional, rather than neutral facial expressions. Moreover, commonly, recognition of static stimulus material was researched. Objective: We assessed recognition of dynamic (closer to real life) negative, positive and neutral facial expressions in individuals characterised by CM, rather than a specific mental disorder. Moreover, we assessed whether they show a negativity bias for neutral facial expressions and whether the presence of one or more mental disorders affects recognition. Methods: Ninety-eight adults with CM experiences (CM+) and 60 non-maltreated (CM−) adult controls watched 200 non-manipulated coloured video sequences, showing 20 neutral and 180 emotional facial expressions, and indicated whether they interpreted each expression as neutral or as one of eight emotions. Results: The CM+ showed significantly lower scores in the recognition of positive, negative and neutral facial expressions than the CM− group (p

ABSTRACTBackground: Post-traumatic growth (PTG) and resilience, regarded as positive psychological change following a traumatic experience, are under-researched across cultures in people exposed to child maltreatment (CM).Objective: We investigated how experiences and the perceived acceptability of CM are related to resilience and PTG in countries with different cultures, living standards, and gross national income.Method: A total of 478 adults from Cameroon (n = 111), Canada (n = 137), Japan (n = 108), and Germany (n = 122) completed an online survey with self-reported questionnaires, including the Brief Resilience Scale and the Post Traumatic Growth Inventory-Short Form.Results: Across countries, self-reported male gender and age were positively associated with resilience, while experiences of physical abuse and emotional maltreatment were negatively associated with resilience. Experiences of emotional maltreatment were positively associated with PTG. Higher levels of PTG and resilience were found amongst Cameroonian participants as compared to other countries.Conclusion: Our results suggest that positive changes following CM can vary significantly across cultures and that experiences of specific CM subtypes, but not the perceived acceptability of CM, may be important for a deeper understanding of how individuals overcome trauma and develop salutogenic outcomes. Our findings may inform CM intervention programmes for an enhanced cultural sensitivity.

Aims of the study: After arriving in host countries, most refugees are confronted with numerous post-migration stressors (e.g., separation from family, discrimination, and employment difficulties). Post-migration living difficulties (PMLDs) significantly contribute to the development and persistence of mental disorders. Effective treatment approaches focusing on reducing post-migration stress are urgently needed. The aim of the present study was to examine the effect of a brief psychological intervention, Problem Management Plus (PM+), on PMLDs among Syrian refugees in two European countries. Methods: We merged data from two single-blind feasibility trials with Syrian refugees experiencing elevated levels of psychological distress and impaired functioning in Switzerland (N = 59) and the Netherlands (N = 60). Participants were randomised to receive either five sessions of PM+ or an enhanced care-as-usual control condition. PMLDs were assessed at baseline and 3 months after the intervention. To estimate treatment effect on PMLD, linear mixed model analysis was performed. Results: Three months after the intervention, participants in the PM+ condition reported significantly fewer PMLDs compared to the control condition. Further analyses at item-level showed that interpersonal and family related PMLDs, such as “worries about family back home” significantly improved over time in the PM+ condition. Conclusions: This exploratory study suggests that brief psychological interventions have the potential to reduce PMLDs in refugees and asylum seekers. The reduction of post-migration stress in turn may subsequently lead to an overall reduction in psychological distress.Clinical Trial Numbers: BASEC Nr. 2017–0117 (Swiss trial) and NL61361.029.17, 7 September 2017 (Dutch trial).

Background The mental health burden among refugees in high-income countries (HICs) is high, whereas access to mental healthcare can be limited.Objective To examine the effectiveness of a peer-provided psychological intervention (Problem Management Plus; PM+) in reducing symptoms of common mental disorders (CMDs) among Syrian refugees in the Netherlands.Methods We conducted a single-blind, randomised controlled trial among adult Syrian refugees recruited in March 2019–December 2021 (No. NTR7552). Individuals with psychological distress (Kessler Psychological Distress Scale (K10) >15) and functional impairment (WHO Disability Assessment Schedule (WHODAS 2.0) >16) were allocated to PM+ in addition to care as usual (PM+/CAU) or CAU only. Participants were reassessed at 1-week and 3-month follow-up. Primary outcome was depression/anxiety combined (Hopkins Symptom Checklist; HSCL-25) at 3-month follow-up. Secondary outcomes included depression (HSCL-25), anxiety (HSCL-25), post-traumatic stress disorder (PTSD) symptoms (PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; PCL-5), impairment (WHODAS 2.0) and self-identified problems (PSYCHLOPS; Psychological Outcomes Profiles). Primary analysis was intention-to-treat.Findings Participants (n=206; mean age=37 years, 62% men) were randomised into PM+/CAU (n=103) or CAU (n=103). At 3-month follow-up, PM+/CAU had greater reductions on depression/anxiety relative to CAU (mean difference −0.25; 95% CI −0.385 to −0.122; p=0.0001, Cohen’s d=0.41). PM+/CAU also showed greater reductions on depression (p=0.0002, Cohen’s d=0.42), anxiety (p=0.001, Cohen’s d=0.27), PTSD symptoms (p=0.0005, Cohen’s d=0.39) and self-identified problems (p=0.03, Cohen’s d=0.26), but not on impairment (p=0.084, Cohen’s d=0.21).Conclusions PM+ effectively reduces symptoms of CMDs among Syrian refugees. A strength was high retention at follow-up. Generalisability is limited by predominantly including refugees with a resident permit.Clinical implications Peer-provided psychological interventions should be considered for scale-up in HICs.

Previous studies report a preference for larger comfortable interpersonal distance (CIPD) in individuals with child maltreatment (CM) when being approached by others. Yet, research on approaching others, as opposed to being approached, as well as on potential effects of social anxiety and depression is lacking. We investigated if CM and depressive symptoms influence CIPD and if social anxiety mediates the possible association of CM and CIPD when approaching a female stranger. One hundred ten participants with CM (CM) and 58 participants without CM (non‐CM) experiences performed the stop‐distance paradigm and stopped first when feeling uncomfortable (D1) and again when feeling very uncomfortable (D2). CM experiences were associated with a preference for larger CIPD, independent of depressive symptoms. All CM subtypes were associated with a larger D2. The relationship between CM and CIPD was partially mediated by social anxiety. These novel findings can help to develop interventions strengthening socially relevant skills and processes in those affected by CM, targeting alterations in social anxiety and depression.

Background: The most used questionnaires for PTSD screening in adults were developed in English. Although many of these questionnaires were translated into other languages, the procedures used to translate them and to evaluate their reliability and validity have not been consistently documented. This comprehensive scoping review aimed to compile the currently available translated and evaluated questionnaires used for PTSD screening, and highlight important gaps in the literature. Objective: This review aimed to map the availability of translated and evaluated screening questionnaires for posttraumatic stress disorder (PTSD) for adults. Methods: All peer-reviewed studies in which a PTSD screening questionnaire for adults was translated, and which reported at least one result of a qualitative and /or quantitative evaluation procedure were included. The literature was searched using Embase, MEDLINE, and APA PsycInfo, citation searches and contributions from study team members. There were no restrictions regarding the target languages of the translations. Data on the translation procedure, the qualitative evaluation, the quantitative evaluation (dimensionality of the questionnaire, reliability, and performance), and open access were extracted. Results: A total of 866 studies were screened, of which 126 were included. Collectively, 128 translations of 12 different questionnaires were found. Out of these, 105 (83.3%) studies used a forward and backward translation procedure, 120 (95.2%) assessed the reliability of the translated questionnaire, 60 (47.6%) the dimensionality, 49 (38.9%) the performance, and 42 (33.3%) used qualitative evaluation procedures. Thirty-four questionnaires (27.0%) were either freely available or accessible on request. Conclusions: The analyses conducted and the description of the methods and results varied substantially, making a quality assessment impractical. Translations into languages spoken in middle- or low-income countries were underrepresented. In addition, only a small proportion of all translated questionnaires were available. Given the need for freely accessible translations, an online repository was developed. HIGHLIGHTS We mapped the availability of translated PTSD screening questionnaires. The quality of the translation and validation processes is very heterogenous. We created a repository for translated, validated PTSD screening questionnaires.

Abstract Background Health care workers are often affected by burnout, resulting in reduced personal well-being and professional functioning. Although emotional exhaustion is considered a core component of burnout, little is known about the dynamics of emotions and their relation to burnout. We used network analysis to investigate the correlation between the density of a negative emotion network, a marker for emotional rigidity in person-specific networks, and burnout severity. Methods Using an ecological momentary assessment design, the intensity of negative emotions of forty-three health care workers and medical students was assessed five times per day (between 6 am and 8 pm) for 17 days. Burnout symptoms were assessed at the end of the study period with the Maslach Burnout Inventory. Multilevel vector autoregressive models were computed to calculate network density of subject-specific temporal networks. The one-sided correlation between network density and burnout severity was assessed. The study protocol and analytic plan were registered prior to the data collection. Results We found a medium-sized correlation between the negative emotion network density and burnout severity at the end of the study period r(45) = .32, 95% CI = .09–1.0, p = .014). Conclusions The strength of the temporal interplay of negative emotions is associated with burnout, highlighting the importance of emotions and emotional exhaustion in reaction to occupational-related distress in health care workers. Moreover, our findings align with previous investigations of emotion network density and impaired psychological functioning, demonstrating the utility of conceptualizing the dynamics of emotions as a network.

Abstract Background Interacting with patients can elicit a myriad of emotions in health-care providers. This may result in satisfaction or put providers at risk for stress-related conditions such as burnout. The present study attempted to identify emotions that promote provider well-being. Following eudaimonic models of well-being, we tested whether certain types of emotions that reflect fulfilment of basic needs (self-worth, bonding with patients) rather than positive emotions in general (as suggested by hedonic models) are linked to well-being. Specifically, we hypothesized that well-being is associated with positive emotions directed at the self, which reflect self-worth, and positive as well as negative emotions (e.g., worry) directed at the patient, which reflect bonding. However, we expected positive emotions directed at an object/situation (e.g., curiosity for a treatment) to be unrelated to well-being, because they do not reflect fulfilment of basic needs. Methods Fifty eight physicians, nurses, and psychotherapists participated in the study. First, in qualitative interviews, they reported their emotions directed at the self, the patient, or an object/situation during distressing interactions with patients. These emotions were categorised into positive emotions directed towards the self, the patient, and an object/situation, and negative emotions directed towards the patient that reflect bonding. Second, providers completed questionnaires to assess their hedonic and eudaimonic well-being. The well-being scores of providers who did and did not experience these emotions were compared. Results Providers who experienced positive emotions directed towards the self or the patient had higher well-being than those who did not. Moreover, for the first time, we found evidence for higher well-being in providers reporting negative patient-directed emotions during distressing interactions. There was no difference between providers who did and did not experience positive object/situation-directed emotions. Conclusions These findings may point towards the importance of “eudaimonic” emotions rather than just positive emotions in interactions with patients. Emotions such as contentment with oneself, joy for the patient’s improvement, and, notably, grief or worry for the patient may build a sense of self-worth and strengthen bonding with the patient. This may explain their association with provider well-being.

Childhood Emotional Maltreatment (CEM) is a significant but under-studied risk factor for impaired mental health, with adolescents being particularly susceptible. This systematic review and meta-analysis, prospectively registered in PROSPERO as CRD42022383005, aims to synthesize the findings of studies investigating the association between CEM and adolescent psychopathology, making it the first attempt to the best of our knowledge. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, a comprehensive search (PubMed, Scopus, PsycINFO, Science Direct, Embase, and ProQuest) yielded 12,224 studies, from which 72 were included in the qualitative synthesis. The meta-analysis was conducted on 76 effect sizes (ranging from 0.01 to 0.57) extracted from 56 studies. The assessment of publication bias utilized funnel plots, Egger's regression test, and the trim and fill method, if required. Additionally, a predictor analysis investigated the influence of study-level variables on the CEM-psychopathology association. Results revealed a significant positive correlation between CEM and adolescent psychopathology (Pooled association: 0.24–0.41) Furthermore, assessment of publication bias indicated no significant bias. The predictor analysis suggested minimal influence of study-level variables. The study underscores the urgent need to address CEM as a crucial risk factor for adolescent psychopathology. The significant positive correlation between CEM and psychopathological outcomes highlights the detrimental effects of CEM on adolescents. Awareness, prevention efforts, and targeted interventions are essential to mitigate these effects. Further studies with culturally diverse and larger sample sizes are required, with emphasis on methodological rigor, given that most of the identified studies showed a high risk of bias.

Despite the well-documented link between child maltreatment (CM) and mental health, evidence suggests substantial variability in the post-traumatic sequelae of CM across cultures. The perceived acceptability of CM in one's community might moderate the association between CM and mental health, but little research has been conducted on it so far. This study examined how the perceived acceptability of CM may influence the relationship between CM experiences and post-traumatic symptoms in individuals from four different continents and if the pattern of associations is the same across countries. We recruited a sample of 478 adults from Cameroon (n = 111), Canada (n = 137), Japan (n = 108), and Germany (n = 122). We administered online questionnaires and performed multiple group moderation analyses for total CM, neglect, physical abuse, emotional maltreatment, sexual abuse, and exposure to domestic violence (DV). A significant positive main effect of CM on post-traumatic symptoms was found in the overall sample and in Cameroon; in Germany, only neglect and emotional maltreatment were positively associated to post-traumatic symptoms. Moderation effects were identified; the perceived acceptability of neglect in Cameroon and Germany and of exposure to DV in Cameroon had a dampening effect on the relationship between CM experiences and post-traumatic symptoms. Our findings confirm that CM experiences entail long-term post-traumatic sequelae that can vary across cultures and CM subtypes and further our understanding of this issue by showing that the perceived acceptability of CM may be an understudied moderator.

Abstract Background Syrian refugees and asylum seekers (SRAs) face multiple stressors after flight, which may vary due to different geographic, economic, cultural and socio-political contexts in the host countries. Past research has recognised the importance of participants’ own perspectives. The aims of this multi-country study were to identify and compare self-reported problems of SRAs between various settings. Methods A semi-structured client-generated outcome measurement was used to collect data among adult SRAs in Jordan (N = 61), Turkey (N = 46) and Switzerland (N = 57) between September 2018 and November 2019. Answers were analysed following thematic analysis. Results Over half of the participants reported practical problems with an emphasis on camp-related problems (Jordan), finances (Turkey), employment (Jordan and Switzerland) and government regulations (Switzerland), followed by psychological, and social issues. Conclusion This study highlights the impact of local contextual factors on wellbeing. The findings emphasise that planning preventative procedures and mental health care services for SRAs need to consider local challenges affecting the population in specific countries.

Background Syrian refugees in Switzerland face several barriers in accessing mental health care. Cost-effective psychological interventions are urgently needed to meet the mental health needs of refugees. Problem Management Plus (PM+) is an evidence-based, psychological intervention delivered by trained non-specialist ‘helpers’. Objective To assess the feasibility and acceptability of PM+ among Syrian refugees in Switzerland. Methods We conducted a single-blind pilot randomized controlled trial (RCT) with Syrian refugees impaired by psychological distress (K10 > 15 and WHODAS 2.0 > 16). Participants were randomized to PM+ or Enhanced Treatment As Usual (ETAU). Participants were assessed at baseline, and 1 week and 3 months after the intervention, and completed measures indexing mental health problems and health care usage. Semi-structured interviews were conducted with different stakeholders. Results N = 59 individuals were randomized into PM+ (n = 31) or ETAU (n = 28). N = 18 stakeholders were interviewed about facilitators and barriers for the implementation of PM+. Retention rates in the trial (67.8%) and mean intervention attendance (M = 3.94 sessions, SD = 1.97) were high. No severe events related to the study were reported. These findings indicate that the trial procedures and PM+ were feasible, acceptable and safe. Conclusions The findings support the conduct of a definitive RCT and show that PM+ might have the potential to be scaled-up in Switzerland. The importance, as well as the challenges, of implementing and scaling-up PM+ in high-income countries, such as Switzerland, are discussed.

Background Childhood maltreatment (CM) is frequently linked to interpersonal problems such as difficulties in social relationships, loneliness, and isolation. These difficulties might partly stem from troubles regulating comfortable interpersonal distance (CIPD). Objective We experimentally investigated whether CM manifests in larger CIPD and whether all subtypes of CM (i.e., physical, emotional, or sexual abuse and physical or emotional neglect) affect CIPD. Methods Using the stop-distance method (i.e. a team member approached participants until the latter indicated discomfort), we assessed CIPD in 84 adults with a self-reported history of CM (24 with depressive symptoms) and 57 adult controls without a history of CM (without depressive symptoms). Results Adults with CM showed a larger CIPD (Mdn = 86 cm) than controls (Mdn = 68 cm), and CIPD was largest for those with CM combined with current depressive symptoms (Mdn = 145 cm) (p’s

Abstract Background More than 120,000 refugees and asylum seekers are currently living in Switzerland. The prevalence of mental disorders among this population is significantly higher than that in the general population. While effective treatment options and cross-cultural, specialized treatment centers exist, they tend to be overloaded by their target populations. General outpatient primary health care providers might be able to compensate for the lack of specialized treatment slots. To date, however, it is unknown how often and under what conditions (e.g., length of waiting lists) refugees and asylum seekers are treated outside of specialized centers and whether there are barriers that prevent providers in outpatient settings from treating more patients in this subgroup. The present study aimed to assess the challenges and barriers faced by psychiatrists and psychotherapists working in outpatient settings in Switzerland in treating refugees and asylum seekers to determine the potential capacity of this group to provide mental health care. Methods An online survey was conducted during the winter of 2017/2018. The survey was constructed in three official languages and took 10–15 min to complete. Spearman’s correlations, Mann-Whitney U-Tests, and Chi-squared tests were conducted to analyze the data. Results Eight hundred and sixty-seven (N = 867) psychotherapists and psychiatrists working in outpatient settings completed the survey: 43% of them reported having treated between 1 and 9 refugees or asylum seekers in the past 12 months, and a further 13% reported treating 10 or more. Interpreters were used for almost every other patient with a refugee or asylum-seeker background. At the same time, the funding of interpreters, as well as the funding of treatment in general, were reported to be the biggest hurdles to treating more refugees and asylum seekers. Conclusions Given the low number of patients rejected for capacity reasons (between 2 and 5%) and the median waiting times for the admission of new patients ranging between 2 and 3 weeks, outpatient primary mental health care providers might treat more refugees and asylum seekers and relieve specialized treatment centers. However, barriers such as lack of funding of interpreters seem to hinder them. Appropriate steps by the authorities are needed to improve the current situation.

Introduction The World Health Organization’s (WHO) scalable psychological interventions, such as Problem Management Plus (PM+) and Step-by-Step (SbS) are designed to be cost-effective non-specialist delivered interventions to reduce symptoms of common mental disorders, such as anxiety, depression and post-traumatic stress disorder (PTSD). The STRENGTHS consortium aims to evaluate the effectiveness, cost-effectiveness and implementation of the individual format of PM+ and its group version (gPM+), as well as of the digital SbS intervention among Syrian refugees in seven countries in Europe and the Middle East. This is a study protocol for a prospective individual participant data (IPD) meta-analysis to evaluate (1) overall effectiveness and cost-effectiveness and (2) treatment moderators of PM+, gPM+ and SbS with Syrian refugees.Methods and analysis Five pilot randomised controlled trials (RCTs) and seven fully powered RCTs conducted within STRENGTHS will be combined into one IPD meta-analytic dataset. The RCTs include Syrian refugees of 18 years and above with elevated psychological distress (Kessler Psychological Distress Scale (K10>15)) and impaired daily functioning (WHO Disability Assessment Schedule 2.0 (WHODAS 2.0>16)). Participants are randomised into the intervention or care as usual control group, and complete follow-up assessments at 1-week, 3-month and 12-month follow-up. Primary outcomes are symptoms of depression and anxiety (25-item Hopkins Symptom Checklist). Secondary outcomes include daily functioning (WHODAS 2.0), PTSD symptoms (PTSD Checklist for DSM-5) and self-identified problems (PSYCHLOPS). We will conduct a one-stage IPD meta-analysis using linear mixed models. Quality of evidence will be assessed using the GRADE approach, and the economic evaluation approach will be assessed using the CHEC-list.Ethics and dissemination Local ethical approval has been obtained for each RCT. This IPD meta-analysis does not require ethical approval. The results of this study will be published in international peer-reviewed journals.
