dc.description.abstractThis study aimed to perform a cross-cultural adaptation of the English version of the Personalized Psychological Flexibility Index into Turkish (T-PPFI). It was conducted among 604 disaster search and rescue volunteers who participated in the 2023 Kahramanmara & sect; earthquakes in Tiirkiye. Exploratory factor analysis supported a three-factor, 15-item structure, and confirmatory factor analysis indicated good fit for the three-factor model. Convergent and divergent validity were supported by a positive correlation with the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT) and negative correlations with the Acceptance and Action Questionnaire-II (AAQ-II) and the Depression Anxiety and Stress Scales-21 (DASS-21). The T-PPFI showed acceptable internal consistency (total score a= .727; w= .712) and high test-retest reliability over 14 days (r= .962). Gender measurement invariance analyses supported comparability of T-PPFI scores across men and women. Hierarchical regression analyses provided evidence for the incremental validity of the T-PPFI beyond AAQ-II and CompACT in predicting DASS-21 outcomes, and higher-order EFA supported construct-level discriminant validity. The findings suggest that the 15-item T-PPFI is a reliable and valid measure of psychological flexibility in Turkish disaster search and rescue volunteers.
