Abstract

Objectives: This study aimed to assess the reliability and validity of the abbreviated Committed Action Questionnaire (CAQ-8) in a cohort of 1635 Chinese university students. Methods: Participants completed the Chinese version of the CAQ-8 along with other standardized measures, including the Acceptance and Action Questionnaire-II (AAQ-II), the Valuing Questionnaire (VQ), the Satisfaction with Life Scale (SWLS), the Depression Anxiety Stress Scales (DASS-21), and the World Health Organization Five-item Well-Being Index (WHO-5). A retest was conducted one month later with 300 valid responses. Results: Exploratory factor analysis (n = 818) identified a 2-factor structure, confirmed through validated factor analysis (n = 817), showing good fit indices (CFI = 0.990, RMSEA = 0.040). Measurement equivalence across genders was established. The CAQ-8 showed significant positive correlations with life satisfaction, mental health, and values, and negative correlations with depression, anxiety, stress, and experiential avoidance. The scale demonstrated good internal consistency (Cronbach’s α = 0.76) and retest reliability (ICC = 0.70). Network analysis confirmed the robustness of the 2-factor model, with item 4 in CAQ-8 identified as a core item. Conclusion: The CAQ-8 is a reliable and valid tool for measuring committed action within the psychological flexibility model in Chinese populations.
