Methods The study sample consisted of Bu-Ali-Sina University students enrolled during the academic year 2016. A total of 329 students were selected based on multistage cluster sampling. To study the psychometric characteristics of the BIPIS, it was first translated with the help of the double-translation technique and then administered along with the Body Dysmorphic Meta-Cognitive Questionnaire and Body Image-Acceptance and Action questionnaire. The collected data was analyzed, and thereafter, its reliability, validity and confirmatory factor analysis were calculated. Results Analysis of the collected data showed that the scale has a reliability of 0.90 to 0.93 alpha coefficients in general and both genders. In addition, the concurrent validity of both genders with the sub-scales of Body Dysmorphic Meta-Cognitive Questionnaire and Body Image-Acceptance and Action Questionnaire was 0.71, 0.62, 0.75, 0.69 and -0.58 for Meta-Cognitive strategies, thought- action fusion, Meta-Cognitive negative and positive beliefs, safety behaviors, and body image-acceptance and action questionnaire respectively. Which in the P<0.01 level was significant. Moreover, the results of the confirmatory factor analysis supported the factor structure of the questionnaire. Conclusion The BIPIS favors psychometric properties among Iranian students. M3 10.18869/nirp.ijpcp.23.1.94 ER -
