Introduction: One of the main concepts of Acceptance and Commitment Therapy (ACT) is the concept of the values of people’s lives that can play a significant role in creating a psychological flexibility. Aim of this study was to investigate the psychometric characteristics of Persian version of Valued Living Questionnaire (VLQ).

Method: In this Correlation-Descriptive study, 369 Undergraduate students of Shahid Beheshti University, Allameh Tabataba’i University and Kharazmi University completed VLQ, Acceptance and Action Questionnaire-II (AAQ-II), short form Health Survey questionnaire (SF-36) and Depression Anxiety Stress Scales-21 (DASS-21). Validity of VLQ was Assessed in terms of Content validity, Construct validity, and Concurrent validity. In order to investigate the reliability of the scale, the internal consistency coefficient (Cronbach's alpha) and test-retest method were used.

Results: The results of the study showed that the test-retest coefficient of four weeks of VLQ was 0.76 and its coefficient of internal consistency for the whole tool was 0.80. Content validity of this questionnaire was evaluated using judgment of five experts on the acceptance and commitment therapist and the Kendall coefficient of consensus for all items of the questionnaire was confirmed. For authentication of Construct validity, the results of exploratory factor analysis proposed the one-factor of VLQ. This factor explained 68% of the total variance. The concurrent validity was assessed through the correlation coefficient of participants' scores in this instrument with their scores in the subscales of SF-36, AAQ-II and DASS-21 (range from 0.58 to 0.87) and obtained results confirmed concurrent validity.

Conclusion: According to obtained results, Persian version of Valued Living Questionnaire is a reliable and valid instrument for assessing values of peoples of Iranian students and can be that used suitable measurement in psychological research, especially researches related to Acceptance and Commitment Therapy.
