This study aimed to create a Persian version of the physical activity questionnaire for Older Children and investigate its psychometric properties. The statistical population has been considered grades 4-8 students in Mazandaran province in 2018, that 864 students (mean age: 11.90 ± 1.19 year) were selected eventually through cluster sampling method from two elementary and junior high schools. First, the original version was translated to Persian language and it was approved by standard back translation method, then completed by the subjects. The psychometric properties of the questionnaire were assessed with reliability analysis, Cronbach's alpha coefficient, intra-class correlation coefficient as well as corrected item total correlations; also validity through content validity index, construct validity by exploratory factor analysis (n= 439) and confirmatory factor analysis (n= 425) and convergent validity with pedometer (n= 328) was calculated. The results showed good fit of the Persian version of physical activity questionnaire for older children. Cronbach's alpha coefficient was 0.89 and intra-class correlation coefficient was 0.92. All corrected item total correlation coefficients were > 0.30. Content validity index was 0.91. Exploratory factor analysis revealed a single-factor structure. Confirmatory factor analysis confirmed the single-factor structure. Correlation between physical activity questionnaire for older children scores with pedometer-based physical activity was 0.41 (P= 0.00). Therefore, this study showed that the Persian version of the Physical Activity Questionnaire for older children (PAQ-C) is a valid and reliable instrument for measuring Iranian older children's physical activity.
