At first, the data was confirmed with the use of back translation methods and check translation accuracy. Then, a confirmatory factor analysis, based on the structural equations model, was done to determine the constructive validity of the questionnaire. To determine its internal consistency, the Cronbach&rsquo;s alpha coefficient was used. The intra-class correlation coefficient (ICC) in the test-retest method was calculated to assess the temporal reliability of items. </span></span></p> <p dir="ltr" style="text-align:justify"><span style="font-size:12px"><span style="font-family:times new roman,times,serif"><strong>Results. </strong>The confirmatory factor analysis results suggested that the approximation square mean root was 0.07 and the comparative fit index was 0.94. Three factors and 11 items were properly verified in the questionnaire. The results of the Cronbach&rsquo;s alpha coefficient and the ICC showed that the CAPIQ has appropriate internal and temporal consistency in answers. </span></span></p> <p dir="ltr" style="text-align:justify"><span style="font-size:12px"><span style="font-family:times new roman,times,serif"><strong>Conclusion. </strong>Therefore, the Persian version of the CAPIQ can be regarded as a valid and reliable tool to be used by the researchers.</span></span></p> Imagery, Social Factor, Validity, Reliability, Factor Analysis 49 59 http://aassjournal.com/browse.php?a_code=A-11-480-2&slc_lang=en&sid=1 Vali Ollah Kashani vkashani@semnan.ac.ir 10031947532846004764 10031947532846004764 Yes Division of Motor Behavior, Department of Physical Education, University of Semnan, Semnan, Iran Behroz Gol Mohamadi gol_b_2005@yahoo.com 10031947532846004765 10031947532846004765 No Division of Motor Behavior, Department of Physical Education, University of Semnan, Semnan, Iran Mansoureh Mokaberian mokaberian@shahroodut.ac.ir 10031947532846004766 10031947532846004766 No Department of Sports Science, Shahrood University Of Technology, Shahrood, Iran
