This will be the first pilot randomized controlled trial (RCT) study that investigate the potential effectiveness of individual PM+ among earthquake survivors residing in container cities in Türkiye. The primary objective of this pilot study will be to test feasibility, acceptability, and potential effectiveness of individual PM+ for Turkish earthquake survivors, using RCT design which is considered the gold standard in research for evaluating effectiveness of interventions. Secondly, this study aims to test trial procedures in preparation for a future larger randomized controlled trial.
On the 6th February, 2023, Türkiye experienced two consecutive earthquakes with magnitudes of 7.7 and 7.6. As a consequence of such a disaster, the increasing prevalence of mental health issues has resulted in increased need and demand for mental health and psychosocial support (MHPSS) services in the country. In order to reach a higher number of people on time, implementation of brief, scalable interventions addressing common mental health problems has garnered significant importance. One such intervention is Problem Management Plus that is developed by World Health Organization for communities that experienced adversities. PM+ is a 5-session psychological intervention that aims to improve common mental health problems by teaching participants evidence-based behavioral strategies (i.e., stress management, problem solving, behavioral activation and strengthening social support). Both the individual and group versions of PM+ were tested for feasibility, acceptability, and effectiveness in various countries among different populations, including the earthquake-affected communities in Nepal.
This study will be the first to test the potential effectiveness of individual PM+ among earthquake survivors in Türkiye. The study will be designed as a pilot randomized controlled trial and the potential effectiveness of individual PM+ will be tested compared to Enhanced-Care as Usual (E-CAU) control group. The study is planned to be conducted at container cities in different earthquake regions (e.g.,Hatay, Adıyaman or Malatya). After the baseline assessment, eligible 60 participants will be randomized to two arms: in either the PM+ (n=30) or only control group (E-CAU; n=30). If they will be randomized into the PM+ condition, the facilitator will plan five consecutive sessions with the participants. The first session will take place no longer than one week after the pre-intervention assessment. The post-intervention assessment through the same measures used in the pretest will take place within 1 week after completion of the fifth session. Follow-up assessment will be conducted one month after the last-session. All study participants including drop-outs will be invited to all outcome assessments. After completion of the follow-up assessment, those in the E-CAU condition will be offered with PM+. The primary outcome measure will be depression and anxiety, posttraumatic stress, psychological distress, psychosocial functioning and self-identified problems will be included as secondary outcome measures.
In order to assess feasibility and acceptability of these interventions, and the possibility of scaling up as well, we will assess the recruitment and consent rates, the percentages of attendance of sessions, the protocol adherence, drop-out rates and qualitative assessments from the process evaluation.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Problem Management Plus (PM+) | Experimental | The experimental group will receive a 5-session individual PM+. |
|
| Enhanced Care as Usual | No Intervention | The control (enhanced care as usual) group will receive the information about freely available psychological support options. E-CAU ranges from standard community care which may include any existing mental health support services available to earthquake survivors in container cities. The participants will be given flyers which include information about the services provided by the government and by non-governmental organizations. After completion of the post and follow-up assessment of experimental group, those in the E-CAU condition will be offered with PM+. |

| Problem Management Plus (PM+) | Behavioral | PM+ consists of five weekly in-person sessions of 90 minutes. The intervention integrates four evidence-based behavioural strategies: arousal reduction using a slow breathing exercise (session 1), problem-solving (session 2), behavioural activation by re-engaging with pleasant and task-oriented activities (session 3) and accessing social support (session 4). Homework practice is scheduled following each session and discussed in the next session. Psychoeducation is delivered in session 1 and relapse prevention is discussed in session |
| Measure | Description | Time Frame |

| Change of the Patient Health Questionnaire-9 (PHQ-9) over time | PHQ-9 is a 9-item questionnaire that aims to measure the depressive symptoms. Each item is scored from 0 (not at all) to 3 (nearly every day) providing a range between 0 and 27. Higher scores indicate more severe depressive symptoms. | change from baseline (one week before the first session of PM+) to post assessment (one week after the last session of PM+); which is expected to last an average of 7 weeks |
| Measure | Description | Time Frame |

| Change of the Generalized Anxiety Disorder-7 (GAD-7) over time | GAD-7 is a 7-item measure of general anxiety symptoms that measures anxiety symptoms. Each item is scored from 0 (not at all) to 3 (nearly every day) providing a range between 0 and 21. Higher scores indicate higher levels of anxiety. | change from baseline (one week before the first session of PM+) to post assessment (one week after the last session of PM+); which is expected to last an average of 7 weeks |
