Pathways towards scaling up Problem Management Plus in Turkey: a theory of change workshop.

BACKGROUND: A considerable evidence base has been produced in recent years highlighting the effectiveness of brief scalable psychological interventions for people living in communities exposed to adversity. However, practical guidance on how to scale up these interventions to wider populations does not exist. In this paper we report on the use of Theory of Change (ToC) to plan the scale up of the World Health Organization's flagship low intensity psychological intervention "Problem Management Plus" (PM+) for Syrian refugees in Turkey. METHODS: We conducted a one-day ToC workshop in Istanbul. ToC is a participatory planning process used in the development, implementation and evaluation of projects. It is similar to driver diagrams or logic models in that it offers a tool to visually present the components needed to reach a desired long-term outcome or impact. The overall aim of ToC is to understand the change process of a complex intervention and to map out causal pathways through which an intervention or strategy has an effect. RESULTS: Twenty-four stakeholders (including governmental officials, mental health providers, officials from international/national non-governmental organisations, conflict and health researchers) participated in the ToC workshop. A ToC map was produced identifying three key elements of scaling up (the resource team; the innovation and the health system; and the user organisation) which are represented in three distinct causal pathways. Context-specific barriers related to the health system and the political environment were identified, and possible strategies for overcoming these challenges were suggested. CONCLUSION: ToC is a valuable methodology to develop an integrated framework for scaling up. The results highlight that the scaling up of PM+ for Syrian refugees in Turkey needs careful planning and investment from different stakeholders at the national level. Our paper provides a theoretical foundation of the scaling up of PM+, and exemplifies for the first time the use of ToC in planning the scaling up of an evidence-based psychological intervention in global mental health

Peer-provided psychological intervention for Syrian refugees: results of a randomised controlled trial on the effectiveness of Problem Management Plus

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

Post-traumatic growth and its predictors among Syrian refugees in Istanbul: A mental health population survey.

AIMS: The negative mental health effects of exposure to trauma are well-documented. However, some individuals are theorized to undergo post-traumatic growth (PTG) after exposure to trauma, potentially experiencing positive psychological change across five domains: appreciation for life, relationships with others, new possibilities in life, personal strength, and spiritual change. PTG is less studied in forcibly displaced populations in low- and middle-income countries. This study aimed to explore levels of PTG and associated factors among Syrian refugee adults living in Istanbul, Turkey. METHODS: A cross-sectional survey was conducted with 1678 respondents. This study analyzed PTG data from 768 individuals as measured by the Post-Traumatic Growth Inventory (PTGI). Descriptive analysis and univariate and multivariate least squares linear regression modeling were used. Factor analysis and Cronbach's alpha tests assessed the psychometric properties of the PTGI. RESULTS: The sample exhibited a moderate level of PTG at 55.94 (SD=22.91, range 0-105). Factor analysis of PTGI revealed only four factors instead of five, and the PTGI yielded high internal reliability (Cronbach's α=0.90). PTG and post-traumatic stress disorder (PTSD) had a curvilinear relationship, with the highest PTG levels experienced by those with moderate PTSD levels. Five other variables were significantly associated with PTG: older age, less education, somatic distress, and history of an overnight stay at a health facility for mental health care were associated with lower PTG, while more years of education were associated with higher PTG. CONCLUSIONS: This study identified the role of the sociodemographic and psychological determinants that influence post-traumatic growth among Syrian refugees in Istanbul. These findings could be used to inform future research and programs seeking to understand PTG in refugees

The associations of hair cortisol and DHEA with posttraumatic stress disorder symptoms in refugees

BACKGROUND: Exposure to traumatic events, ongoing adversity, and posttraumatic stress disorder (PTSD) are associated with altered activity of the hypothalamic-pituitary-adrenal (HPA) axis, but findings are mixed. This may be explained in part by heterogeneity in PTSD symptom profiles. AIM: The aim of this study was to investigate the complex relationships between the number of traumatic events and post-displacement stressors, individual symptoms of PTSD, and HPA-axis hormones cortisol and dehydroepiandrosterone (DHEA) in refugees. METHODS: Adult (18+ years) Syrian refugees with increased levels of distress participating in a randomized controlled trial completed baseline measures to assess traumatic events (trauma checklist), post-displacement stressors (Post-Migration Living Difficulties checklist), symptoms of PTSD (PTSD Checklist for DSM-5; PCL-5), and provided a hair sample for additional stress hormone analyses. We used R-packages qgraph and bootnet to perform network analysis on the number of traumatic events and post-displacement stressors, individual symptoms of PTSD, and HPA-axis hormones cortisol and DHEA. The final network model was corrected for depression severity. RESULTS: 115 (53% male, M age = 36.9, SD = 12.7) of 206 participants provided a hair sample. A higher number of traumatic events was directly associated with three symptoms of the PTSD cluster arousal and reactivity, i.e., sleep disturbance, hypervigilance and physiological reactivity, and with three other PTSD symptoms, namely flashbacks, avoidance of reminders, and self-destructive behavior. A higher number of post-displacement stressors was associated with four symptoms of the PTSD cluster cognition and mood, i.e., trauma-related amnesia, negative beliefs, blaming of self/others, and detachment, as well as with intrusive thoughts, sleep disturbance, hypervigilance, and exaggerated startle response. The number of traumatic events and post-displacement stressors were not associated with cortisol or DHEA. Cortisol was positively associated with two symptoms of the PTSD cluster cognition and mood, i.e., negative beliefs and negative trauma-related emotions, and negatively associated with avoidance of reminders. DHEA was positively associated with restricted affect and with three symptoms of the PTSD symptom cluster arousal and reactivity, i.e., irritability/anger, sleep disturbance, and self-destructive behavior, and negatively associated with avoidance of thoughts. CONCLUSIONS: This study demonstrated that exposure to traumatic events and post-displacement stressors is not related to cortisol and DHEA, but that cortisol and DHEA are differentially related to individual symptoms of PTSD. While lower levels of both cortisol and DHEA were associated with increased avoidance, higher levels of cortisol were mostly associated with symptoms of the PTSD cluster cognition and mood and higher levels of DHEA were mostly associated with symptoms of the PTSD cluster arousal and reactivity. These findings contribute to explaining the variability of findings in the literature on HPA-axis activity in PTSD. ETHICS: The study was approved by the Research Ethics Review Committee at VU Medical Center, the Netherlands (Protocol ID: NL61361.029.17, 7 September 2017) and prospectively registered online (https://www.trialregister.nl/trial/6665)

Prevalence and predictors of common mental disorders among Syrian refugees in Istanbul, Turkey: a cross-sectional study.

PURPOSE: The war in Syria has created the greatest refugee crisis in the twenty-first century. Turkey hosts the highest number of registered Syrian refugees, who are at increased risk of common mental disorders because of their exposure to war, violence and post-displacement stressors. The aim of this paper is to examine the prevalence and predictors of anxiety, depression, and post-traumatic stress disorder (PTSD) symptoms among Syrian refugees living in Turkey. METHODS: A cross-sectional survey of adult Syrian refugees was conducted between February and May 2018 in Istanbul (Sultanbeyli district). Participants (N = 1678) were randomly selected through the registration system of the district municipality. The Hopkins Symptoms Checklist (HSCL-25) was used to measure anxiety and depression and the Posttraumatic Stress Disorder (PTSD) Checklist (PCL-5) assessed posttraumatic stress. Descriptive and multivariate regression analyses were used. RESULTS: The prevalence of symptoms of anxiety, depression and PTSD were 36.1%, 34.7% and 19.6%, respectively. Comorbidity was high. Regression analyses identified several socio-demographic, health and post-displacement variables that predicted common mental disorders including: being female, facing economic difficulties, previous trauma experience, and unmet need for social support, safety, law and justice. A lifetime history of mental health treatment and problems accessing adequate healthcare were associated with depression and anxiety but not with PTSD. CONCLUSIONS: Mental disorder symptoms are highly prevalent among Syrian refugees in Turkey. The association with post-displacement factors points to the importance of comprehensive health and social services that can address these social, economic and cultural stressors

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

Scalable psychological interventions for Syrian refugees in Europe and the Middle East: STRENGTHS study protocol for a prospective individual participant data meta-analysis

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

A System Innovation Perspective on the Potential for Scaling Up New Psychological Interventions for Refugees

In recent years, a range of brief protocolised psychological interventions like Problem Management Plus have been developed. Such 'scalable psychological interventions' are meant to be delivered by nonspecialists which can greatly increase access to psychological therapies for people affected by adversity, including forced displacement. However, embedding new interventions into mainstream practices is challenging. Novel interventions can remain in the research phase for a long time or stop altogether, which minimises their intended impact and reach. In this conceptual paper we propose a 'system innovation perspective' on scaling up new psychological interventions for refugees and argue that existing mental health systems often need to change to integrate new interventions in a sustainable way. We present a conceptual framework, which includes ideas on cycles of deepening (learning by doing), broadening (repeating and linking), and scaling up (embedding) and the multilevel and constellation perspective. This framework has been operationalised in our scalability research as part of the STRENGTHS study in which we increase our understanding of the opportunities for scaling up four new psychological interventions in eight countries hosting Syrian refugees, including in Europe (Germany, Netherlands, Sweden and Switzerland) and the Middle East (Egypt, Jordan, Turkey and Lebanon). Key implications for practice Researchers and practitioners involved in implementing and evaluating scalable psychological interventions such as Problem Management Plus should consider the inclusion of scalability assessments to increase understanding about the potential for integrating such innovations into mainstream services. A system innovation perspective views scaling up as the integration of an innovation into mainstream practices and suggests that mental health systems commonly need to change in order to effectively adopt new interventions, allowing them to reach their desired impact at scale and in a sustainable way. An improved understanding of the scalability of novel psychological interventions, including the potential (systemic) barriers and facilitators for scaling up, will provide essential knowledge for those involved in decision-making, implementation and evaluation of the further scale up of such interventions

Scalability of a task-sharing psychological intervention for refugees: A qualitative study in the Netherlands

Mental health systems across the world struggle to meet the needs of present and future populations. People affected by war and forced displacement, such as refugees, have especially high unmet psychological needs. Shifting tasks from mental health specialists to less specialised providers is increasingly opted as an innovative solution to overcome the mental health care gap. Yet little is known about how task-sharing interventions for refugees can be implemented on a larger scale and integrated in existing systems. In this article, we use a system innovation perspective to examine the factors influencing the potential for scaling up a task-sharing psychological intervention for refugees called ‘Problem Management Plus’ (PM+) in the Netherlands. Semi-structured interviews were conducted with individuals (n=42) knowledgeable about PM+ and the Dutch mental health system for refugees. Findings suggest that the feasibility of wider implementation largely depends on whether barriers like stigma, attrition, fragmentation, competition, legal, and financial challenges can be overcome. Formalising the roles of new non-specialist workers will be important, including developing structures for their accreditation and supervision. There are various possibilities for institutional anchoring of the innovation: in asylum centres, formal health care, and communities. The integration scenarios identified in this study need to be tested, evaluated, refined, and reported in future implementation research
