Brief summary

The current refugee crisis across the Middle East and Europe has large effects on individual refugees' psychological well-being, as well as on the healthcare systems of countries hosting refugees. For example, in Switzerland patients sometimes have to wait up to 12 months for the specific psychological treatment due to a lack of specialists. To address this problem the WHO has developed Problem Management Plus (PM+), a brief (five sessions), low-intensity psychological intervention, delivered by paraprofessionals, that addresses common mental disorders in people in communities affected by adversity. The effectiveness and implementation of PM+ has never been examined in Switzerland before, this is the aim of the current randomized controlled trial.

Detailed description

Recent crises in the Middle East have resulted in an unprecedented increase in the worldwide number of refugees and asylum seekers. Switzerland (CH) is strongly affected by this crisis too.There are currently about 19'000 Syrian refugees and asylum seekers in Switzerland. A similar number of other Arabic-speaking individuals have applied for asylum in Switzerland since 2011. Due to the ongoing war in the MENA region, it is unlikely that this kind of migration and flight will resolve within the next years. Refugees have typically been exposed to multiple stressors related to war and displacement including loss of family members, destruction of homes and livelihoods and human rights violations such as sexual violence or torture. They have often undertaken a risky and stressful flight leaving their homes for an unknown future. Accordingly, various studies have shown that refugees are at considerable risk of developing common mental disorders, including depression, anxiety, posttraumatic stress disorder (PTSD) and related somatic health symptoms. According to the UNHCR, 85% of all displaced persons are hosted in third-world countries where appropriate mental health care is often not available. However, Western health systems are also often unable to appropriately cover the needs of this particularly vulnerable population regarding prevention and treatment of mental health problems. As a response to this situation, the WHO developed the low-intensity Problem Management Plus (PM+) programs, a new generation of short, resource-sparing, trans-diagnostic (i.e., not specifically aimed at treating a certain mental disorder) programs to reduce common mental health symptoms and improve psychosocial functioning. PM+ is based on the WHO treatment guidelines for conditions related to stress. PM+ is a 5-sessions intervention aimed at reducing symptoms of depression, anxiety, PTSD, and related conditions, is delivered by trained non-specialized workers or lay people, and is available in individual and group delivery formats for both children and adults. It comprises evidence-based techniques of (a) problem solving, (b) stress management, (c) behavioral activation, and (d) accessing social support. PM+ has been successfully tested for effectiveness in Kenya and Pakistan. The STRENGTHS (Syrian REfuGees MeNTal HealTH Care Systems) study aims at evaluating the effectiveness and implementation of PM+ with Syrian refugees in different settings in low- and high-resource countries. The study consortium includes international experts in the domains of trauma and public mental health as well as representatives of WHO and UNHCR. The Zürich study site has been consigned to examine PM+ with adult refugees in an individual treatment setting in Switzerland. At the same time, similar studies in other countries will be undertaken. Despite the objective of these studies to implement and evaluate the effectiveness of PM+ in refugees, each research institution acts independently. Moreover, the other studies will be completed in different treatment settings - i.e., in children and adolescents (Lebanon), in groups (Turkey and Netherlands), and internet-delivered PM+ (Germany and Egypt). To date, the effectiveness and implementation of PM+ has not been investigated in a highly industrialized country, such as Switzerland. In the present study, the investigators will evaluate the effectiveness and implementation of PM+ in Arabic speaking refugees in Switzerland.

Interventions

Problem Management Plus (PM+) is a new, brief, psychological intervention program based on CBT techniques that are empirically supported and formally recommended by the WHO. The full protocol was developed by the WHO and the University of New South Wales, Australia. The manual involves the following empirically supported elements: problem solving plus stress management, behavioural activation, facing fears, and accessing social support. These elements have been recommended in recent WHO guidelines.

Masking description

All instruments and questions will be administered using tablets by trained research staff blind to the allocation status of the participants.

Intervention model description

The definitive RCT will inform us about the effectiveness and implementation of the intervention. After the baseline assessment, three hundred eighty participants (N = 380) will be involved in the exploratory RCT (assigned to either the PM+ intervention (n=190) or the ETAU control condition (n=190)).

Design outcomes

Primary

MeasureTime frameDescription
Change in psychological distressBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentChange of psychological distress measured with the Hopkins Symptom Checklist (HSCL-25) serves as primary beneficiary-related health outcome. The 25 items are rated on a scale from 1 to 4. Higher scores indicate more pronounced symptom severity.

Secondary

MeasureTime frameDescription
Change in posttraumatic stress disorder symptomsBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentChange in posttraumatic stress disorder symptoms measured with the PTSD Checklist for DSM-5 (PCL-5). Responses are scored on a scale from 0 to 4 with higher scores indicating more pronounced symptom severity.
Change in functional disabilityScreening, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentChange in functional disability measured with the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0). The items are rated on a scale from 1 to 5. Higher scores indicate more pronounced functional disability.

Other

MeasureTime frameDescription
Somatization and somatic symptomsBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentSomatization and somatic symptoms will be assessed using the Patient Health Questionnaire-15 (PHQ-15). Items are rated on a scale from 1 to 3. Higher scores indicate higher symptom severity.
Level of integrationScreening, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentLevel of integration will be measured using the Immigration Policy Lab Integration Index (IPL-12).

Reponses are given on a scale from 1 to 4 with higher scores representing higher general self-efficacy.
Attitudes towards mental healthBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentAttitudes towards mental health will be measured with with a set of selected questions (e.g. Mentally ill people tend to be violent).This questionnaire has been used with Syrian refugees in previous research.
Exposure to traumatic eventsMeasured at baseline assessment and 12-months follow up onlyExposure to traumatic events will be assessed using the Traumatic Events (TE) - a combination of two standardized questionnaires, namely the Life Events Checklist and the Harvard Trauma Questionnaire.
Cost of CareBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessmentThe Client Service Receipt Inventory (CSRI) was developed for the collection of data on service utilization and related characteristics of people with mental disorders, as the basis for calculating the costs of care for mental health cost-effectiveness research.
Access to health care servicesBaseline assessmentA set of question regarding previous contact with the mental health care services and the previous experiences regarding the utilization of any forms of mental support (own questionnaire).
Assessing the extent to which the strategies taught in PM+ are used before and after the study participation with the Reducing Tension ChecklistBaseline assessment, 1 week post-intervention assessment (6 weeks after baseline), 3 month post-intervention assessment (4-4.5 months after baseline), 12 month post intervention assessment.The outcome is measured with a nine-item scale that was developed to assess the extent to which the participants perceives that they use the specific strategies, which are trained during the study intervention. The items are rated on a scale from 0 to 4. Higher scores represent greater usage of the strategies.
