AbstractCommitted action is a key component of the psychological flexibility model that recently has been applied in chronic pain settings. Developed within the Western context, the 8-item Committed Action Questionnaire (CAQ-8) demonstrated good psychometric properties. This study aimed to translate the original English version of the CAQ-8 into Chinese (ChCAQ-8) and to assess its reliability, factor structure and concurrent criterion validity. A total of 210 Chinese patients with chronic pain completed the ChCAQ-8, the Chronic Pain Grade, the Pain Catastrophizing Scale, and the depression subscale of the Hospital Anxiety and Depression Scale. Results of confirmatory factor analysis showed both the 2-factor correlated (CFI = .99) and hierarchical (CFI = .98) models met the minimum acceptable fit criterion. The 2 subscales and the entire scale of ChCAQ-8 demonstrated good internal consistency (Cronbach's αs ranging .70-.86). The ChCAQ-8 negative subscale score was significantly correlated with pain intensity, disability, pain catastrophizing, and depression in the expected direction. The ChCAQ-8 positive subscale was significantly correlated with pain castastrophizing and depression. Results of multivariate regression modeling showed the ChCAQ-8 negative subscale predicted depression (std β = .19, p < .01) and disability (std β = .14, p < .05), after adjusting for pain intensity, pain duration and pain catastrophizing. Our findings offer preliminary data for the reliability, factorial and concurrent criterion validity of the ChCAQ-8 in the Chinese population.
