Psychometric Properties of the Committed Action Questionnaire, the Persian Version

This study aimed to evaluate the psychometric properties of the Persian version of the Committed Action Questionnaire (CAQ-8) in a non-clinical sample. The study evaluated the factor analyses, reliability, and validity of the CAQ-8 in an Iranian sample.

The psychometric properties of the CAQ-8 were investigated in a Persian student (n=180), through convenient sampling for data gathering. Participants filled out a battery of questionnaires, including CAQ-8, medical outcomes study questionnaire 36-item Short-Form Health Survey (SF-36), Acceptance and Action Questionnaire (AAQ-II), and Depression, Anxiety, And Stress Scale (DASS-21). Confirmatory factor analyses and goodness of fit indexes were used to examine the reliability and validity of the Persian version of the CAQ-8.

The Persian version of the CAQ-8 revealed satisfactory levels of internal consistency (α=0.77), and significant association with various indexes of theoretically-related instruments such as DASS-21, SF-36, and AAQ-II. Confirmatory factor analyses demonstrated that the Persian version of the CAQ-8 yielded a 7-item questionnaire by the two-factor model. 

The Persian version of CAQ appears to be a valid, reliable, and adequate measure for the assessment of the concept of committed action in the Iranian sample.
