The aim of this study is to develop a post-earthquake, trauma-focused Acceptance and Commitment Therapy (ACT)-based psychosocial intervention program (DeST-ACT) and to examine its effectiveness, feasibility, and acceptability of this program in enhancing life satisfaction and psychological flexibility in individuals exposed to earthquake trauma. In this regard, the main hypothesis is that the DeST-ACT psychosocial intervention program is effective, feasible, and acceptable among individuals exposed to earthquake trauma, including both primary and secondary outcomes of the program.
This quantitative, randomized controlled trial involves two groups and includes a pre-test and repeated post-tests. The study aims to assess the effectiveness, feasibility, and acceptability of the developed DeST-ACT program in addressing post-traumatic stress disorder, psychological flexibility, life satisfaction, values-based living, and depression-anxiety-stress levels in individuals affected by the February 6, 2023 earthquake. Participants will be randomly assigned to experimental and control groups in a 1:1 ratio using an internet-based block randomization program. The DeST-ACT psychosocial intervention program consists of a 4-session online intervention supported by self-help materials. Each session in the 4-week program is held once a week for 50 minutes. The main hypotheses are: * The intervention group will demonstrate a significant decrease in Post Traumatic Stress Disorder (PTSD) and depression-anxiety-stress levels compared to the control group. * The intervention group will experience a greater increase in values-based living, life satisfaction, and psychological flexibility over time compared to the control group. * The intervention group will demonstrate a significant decrease in PTSD and depression-anxiety-stress levels compared to baseline measures. * The intervention group will experience a greater increase in values-based living, life satisfaction, and psychological flexibility over time compared to baseline measures.

PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5 (PCL-5)
The PCL-5 was developed based on the diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders-5, and its aim is to evaluate PTSD symptoms. The scale consists of 20 items rated on a 5-point Likert scale. Scores above 47 are indicative of PTSD.
Time frame: At baseline, after 4 weeks, after 8 weeks
Depression Anxiety and Stress Scale 21 (DASS-21)
The DASS-21 measures the dimensions of depression, stress, and anxiety. The scale consists of 21 items rated on a 4-point Likert scale ranging from 0 (Never) to 4 (Always) with scores ranging from a minimum of 0 to a maximum of 84. The Cronbach's alpha values for the scale, based on Turkish validity and reliability studies, are 0.80 for anxiety, 0.82 for depression, and 0.75 for stress.
Time frame: At baseline, after 4 weeks, after 8 weeks
Engaged Living Scale
The Engaged Living Scale is designed to evaluate values-based living. It consists of 16 items rated on a 5-point Likert scale, ranging from 1 (Totally Agree) to 5 (Totally Disagree), with scores ranging from a minimum of 16 to a maximum of 80. The scale, for which Turkish validity and reliability studies have been conducted, has two sub-dimensions: "valued living" and "life fulfillment." The Cronbach's alpha value for the Turkish version of the scale is 0.91, with 0.87 for the valued living sub-dimension and 0.86 for the life fulfillment sub-dimension.
Time frame: At baseline, after 4 weeks, after 8 weeks
Acceptance and Action Questionnaire-2 (AAQ-2)
The AAQ-2 is a measure designed to evaluate experiential avoidance. The scale consists of 7 items rated on a 7-point Likert scale, with scores ranging from a minimum of 7 to a maximum of 49. Higher scores indicate greater experiential avoidance.
Time frame: At baseline, after 4 weeks, after 8 weeks
Therapy Satisfaction Questionnaire
It is a semi-structured form designed by the researchers to assess acceptability and perceived effectiveness. The form consists of 10 questions, each scored on a scale from 0 (not at all) to 4 (completely).
Time frame: after 4 week
Drop Rate
To evaluate acceptability, participants' attendance rates to the program will be recorded.
Time frame: after 8 weeks
