Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to test the pilot effectiveness of Cognitive Processing Therapy (CPT) in decreasing psychological distress and post-traumatic stress disorder (PTSD) symptoms and increasing well-being in earthquake survivors in Türkiye, using randomized controlled trial study design, which is considered the gold standard in research for evaluating the effectiveness of interventions. This pilot study will help to identify any further adaptations required prior to further effectiveness testing in a large cluster randomized controlled trial.

Study hypothesis:

Hypothesis 1: The participants who receive the CPT will have a significantly higher decrease in PTSD symptoms compared to the participants in the care-as-usual control group at the post-assessment.

Hypothesis 2: The participants who receive the CPT will have a significantly higher decrease in depressive symptom severity compared to the participants in the care-as-usual control group at the post-assessment.

Hypothesis 4: The participants who receive the CPT will have a significantly higher decrease in anxiety severity compared to the participants in the care-as-usual control group at the post-assessment.

Hypothesis 5: The participants who receive the CPT will have a significantly higher increase in well-being compared to the participants in the care-as-usual control group at post-assessment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Two large earthquakes struck Türkiye on the 6th of February 2023, affecting more than 14 million people, around 16% of the population, including more than 45.000 lost and 3.3 million displaced. Considering the current scale of the recent earthquakes in Türkiye, implementing and disseminating evidence-based psychosocial interventions, especially trauma-focused treatment approaches such as Cognitive Processing Therapy (CPT), is crucial in order to respond to the increasing mental health needs of the earthquake survivors. Cognitive Processing Therapy (CPT) is a cognitive behavioral treatment for PTSD consisting of 12 one-hour sessions. CPT is delivered in three phases: education, processing, and challenging. The manualized treatment focuses on challenging beliefs and assumptions related to the trauma, oneself, and the world. Randomized clinical trials have revealed that CPT is an effective treatment for PTSD and other comorbid conditions in a variety of civilian trauma populations.

The study will be designed as a pilot randomized controlled trial, and the potential effectiveness of individual CPT will be tested compared to the Enhanced-Care as Usual (E-CAU) control group. CPT will be implemented on Zoom, which is an online platform with HIPAA compliance. After the baseline assessment, 30 eligible participants will be randomized to two arms: in either the CPT (n =15) or only the control group (E-CAU; n=15). The first session will take place no longer than one week after the pre-intervention assessment. The post-intervention assessment through the same measures will be scheduled six weeks after the pre-intervention assessment (i.e., one week after the 12th CPT session). The follow-up assessment will be conducted one month after the post-assessment. All study participants, including dropouts, will be invited to all outcome assessments. The primary outcome is post-traumatic stress disorder, and the following are the secondary clinical outcomes: symptoms of depression, anxiety, and well-being.

Group Type EXPERIMENTAL

Cognitive Processing Therapy

Intervention Type OTHER

Cognitive Processing Therapy (CPT). CPT is a cognitive behavioral treatment for PTSD consisting of 12 one-hour sessions. Prior to engaging in therapy, one session will be devoted to gathering information regarding psychosocial history, trauma, and current functioning. The following sessions will follow the standard outpatient CPT protocol. The standard outpatient CPT consists of 12 one-hour sessions conducted over a 6- to 12-week period. An additional 3 weeks will be provided in case of participant and therapist vacation and/or sick days. CPT is delivered in three phases: education, processing, and challenging. The manualized treatment focuses on challenging beliefs and assumptions related to the trauma, oneself, and the world.

Control group

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 CPT
