Abstract

The Avoidance and Fusion Questionnaire for Youth (AFQ-Y8) was adapted to gauge psychological inflexibility among young people in a Turkish sample. The current study investigated the factorial structure, incremental validity, measurement invariance across age and gender, and test-retest reliability of the AFQ-Y8 with a sample of 968 high school students (boys = 437, girls = 531). The results confirm the factorial structure associated with psychological inflexibility. Furthermore, the AFQ-Y8 demonstrated a positive correlation with adverse psychological health outcomes. The analysis also supported measurement invariance across different age and gender groups. Additionally, psychological inflexibility exhibited incremental validity in relation to anxiety and depression. In summary, the results indicate that the Turkish AFQ-Y8 is a reliable and valid instrument for measuring psychological inflexibility in adolescents. The Turkish AFQ-Y8 may prove useful in cross-cultural research on psychological inflexibility.

期刊介绍： The Journal of Contextual Behavioral Science is the official journal of the Association for Contextual Behavioral Science (ACBS). Contextual Behavioral Science is a systematic and pragmatic approach to the understanding of behavior, the solution of human problems, and the promotion of human growth and development. Contextual Behavioral Science uses functional principles and theories to analyze and modify action embedded in its historical and situational context. The goal is to predict and influence behavior, with precision, scope, and depth, across all behavioral domains and all levels of analysis, so as to help create a behavioral science that is more adequate to the challenge of the human condition.
