Abstract
Introductoin: Acceptance and commitment therapy is one of the third-generation therapies that are of great interest to researchers. Numerous studies have examined the specific processes of ACT and today there is a strong focus on the development of specific, single-act evaluation methods. The purpose of the present study was to determine the validity and reliability of the Comprehensive Assessment of Acceptance and Commitment Therapy processes (compact) Scale in non-clinical Iranian samples.
Method: In this study, 338 undergraduate students of Tehran University completed the Comprehensive Assessment of Acceptance and Commitment Therapy Processes Scale, Acceptance and Act Questionnaire (AAQ), Marlowe Crown Social Desirability Scale (MCSD), The Short Form Health Survey Questionnaire (SF-12), Depression, Anxiety and Stress Scale (DASS-21), and Wilson's Valued Living Questionnaire (VLQ) were used to measure convergent and divergent validity. The scale was also tested using test-retest and internal consistency.
Results: The results showed that the validity of the test using the Omega coefficient of 0.84 as well as test-retest validity of the Comprehensive Acceptance and Commitment Therapy Scale was 0.58 (p <0.01). The convergent and divergent validity of the questionnaire was confirmed based on the correlations obtained with other questionnaires.
Discussion and Conclusion: Based on the results of the present study, the Iranian version of the Comprehensive Assessment of Acceptance and Commitment Therapy Process Scale is a valid and reliable tool for evaluating specific Acceptance and Commitment Therapy processes and psychological flexibility in nonclinical samples and can be used in clinical trials. Psychological research, especially research related to acceptance and commitment therapy, and clinical cases with appropriate caution
