Implementation of Problem Management Plus (PM+) in Adult Syrian Refugees in Turkey: Pilot (STRENGTHS)

To implement Problem Management Plus (PM+) in Syrian refugees with this pilot study in Turkey with the aim of informing the definitive RCT about drop-out rates and estimated effect sizes.

The STRENGTHS (Syrian REfuGees MeNTal HealTH Care Systems) study is a 5-year study that started in January 2017 with funding from the European Commission Horizon 2020 scheme and Turkey is one of the sites that this study will be conducted. The main aim of STRENGTHS in Turkey is to evaluate the feasibility, acceptability, effectiveness and cost-effectiveness of the culturally adapted psychological intervention Problem Management Plus (PM+) intervention for adult Syrian refugees in Turkey. The current trial registration is for the pilot trial to investigate the feasibility and acceptability (e.g., obtain estimates of drop-out rates), to inform a full-scale, definitive randomized controlled trial. Study participants (n=60) will consist of adult Syrian refugees (18 years and older) in Turkey with self-reported functional impairment (WHODAS 2.0 >16) and elevated psychological distress (K10 >15.9). Participants will be randomly allocated either to the treatment group who will receive five sessions of PM+ or to the enhanced care-as-usual (E-CAU) group. Participants in the comparison group will receive E-CAU only. The primary outcome will be the decrease in psychological distress from baseline to three-month post-intervention assessment, measured through the Hopkins Symptoms Checklist (HSCL-25).

30 participants will be randomly assigned to E-CAU with PM+ group. The PM+ is developed by the World Health Organization (WHO) especially for the communities who are exposed to adversity. PM+ (Dawson et al., 2015) belongs to a set of programs which are low-intensity, shorter, less expensive and trans-diagnostic (i.e., not condition-specific, but targeted at a broader set of symptoms of common mental disorders) programs to reduce common mental health symptoms (including depression, anxiety and stress symptoms) and improve psychosocial functioning.

30 participants will be randomly assigned to E-CAU group. CAU ranges from the free health services government provides to Refugee and Asylum Seekers Assistance and Solidarity Association's (RASASA) mental health services which are provided by the Psychological Support Unit (MHPSS Support Unit) which includes counselling as well. The enhanced care arm (CAU, with the addition of a referral document), is to be used as a benchmark for measuring the effectiveness of STRENGTHS's intervention, which is Problem Management Plus (PM+).

This intervention is based on the WHO treatment guidelines for conditions related to stress (WHO, 2013). It is a 5-session intervention that is delivered by trained non-specialized workers or lay people, and is available in individual and group delivery formats for both children and adults. PM+ includes evidence-based techniques such as; problem solving, stress management, behavioral activation, and accessing social support. It has proved to be effective by two randomized controlled trials (RCTs) in Kenya and Pakistan (Bryant, Dawson, Schafer, Sijbrandij, & van Ommeren, 2016; Rahman, Hamdani, Awan, Bryant, Dawson, Khan, Mukhtar-ul-Haq Azeemi, et al., 2016).

The aim is to measure the change in psychological distress. Sub-scales can be calculated for depression (13 items) and anxiety symptoms (10 items). There are two items related to somatic symptoms. The items are rated on a 1-4 point Likert scale, with a well-validated cut-off score of 1.75. The current study will primarily look at the total score in which the lower values represent a better outcome. Furthermore, aim is to examine changes in caseness in depression, a cut-off score for the depression sub-scale of 2.1 will be used.

Change from baseline assessment, at 1 week post-intervention assessment (6 weeks after baseline), and change from post-assessment at 3 month post-intervention assessment (4-4.5 months after baseline)

The aim is to measure the change in PTSD symptoms. PCL-5 is a 20-item checklist corresponding with the 20 DSM-5 PTSD symptoms. Items are rated on a 0-4 scale and add up to a total severity score of 80, with higher scores indicating worse symptomatology. The current study will primarily look at the total score in which the lower values represent a better outcome.

Change from baseline assessment, at 1 week post-intervention assessment (6 weeks after baseline), and change from post intervention assessment at 3 month post-intervention assessment (4-4.5 months after baseline)

The aim is to assess the change in self-identified problems. PSYCHLOPS consists of four questions. It contains three domains: 2 questions on problems, 1 question on function, and 1 question on well-being. Participants are asked to give free text responses to the problem and function domains. Responses are scored on a 0-5 scale producing a maximum score of 20 (six points per domain). The current study will primarily look at the total score in which the lower values represent a better outcome.

Change from baseline assessment, at 1 week post-intervention assessment (6 weeks after baseline), and change from post intervention assessment at 3 month post-intervention assessment (4-4.5 months after baseline)

The aim is to measure the change in the cost of care. 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. The current study will look at the change in the cost of care.

Change from baseline assessment, at 1 week post-intervention assessment (6 weeks after baseline), and change from post-assessment at 3 month post-intervention assessment (4-4.5 months after baseline)

The aim is to assess the change in access to health care. The questionnaire will include 70 questions on perceived access to health care. 57 of those questions will be two-way closed ended questions (yes or no) with the addition of the items "don't know" and "refused to answer". 13 of these questions are asking the type of help received (counselling/psychotherapy, psychological support, and medicines) with the addition of the items "don't know" and "refused to answer". The current study will look at the change in the access to health care.

Change from baseline assessment, at 1 week post-intervention assessment (6 weeks after baseline), and change from the post-intervention assessment at 3 month post-intervention assessment (4-4.5 months after baseline)

Inclusion Criteria: Adults of 18 years or above Syrian under temporary protection status Arabic-speaking Elevated levels of psychological distress (K10 >15.9) and reduced psychosocial functioning (WHODAS 2.0 >16) Exclusion Criteria: Acute medical conditions Imminent suicide risk or expressed acute needs/protection risks (e.g., a young woman who expresses that she is at acute risk of being assaulted or killed) Severe mental disorder (psychotic disorders, substance-dependence) Severe cognitive impairment (e.g., severe intellectual disability or dementia)

The STRENGTHS project is consisted of various partners from different sites (such as the Netherlands, Jordan, Germany etc.). It is planned that the individual sites will be sharing their data with the researchers who are from these project partners. In addition to this, the partners will use the same Study Protocol while adapting it to their site.

The STRENGTHS project is a five year project which started in 2017. The individual participant data will be available for the other partners during the project which is between 2017 and 2022.
