Background: Although physical activity (PA) is an important determinant of health, physically disabled individuals tend to have a sedentary lifestyle. The Barriers to Physical Activity Questionnaire for People with Mobility Impairments (BPAQ-MI) is a self-report instrument evaluating PA barriers. This study was intended to evaluate the validity and reliability of the Persian version of BPAQ-MI (P-BPAQ-MI) and to report the prevalence and severity of PA barriers among Persian-speaking individuals. Methods: The translation and back translation of the BPAQ-MI was conducted according to an internationally accepted guideline and tested on 163 participants to assess its reliability and validity. Internal consistency and test–retest reliability were analyzed using Cronbach alpha and Spearman correlation coefficient. Convergent construct validity was established by comparing the scores of P-BPAQ-MI and The Baecke Habitual Physical Activity Questionnaire. Known-groups construct validity was assessed with regard to type of assistive device and sex of the individual. Prevalence and severity of the barriers were reported by computing the percentage and means of "yes" answers. Results: The P-BPAQ-MI domains demonstrated very good internal consistency (Cronbach alpha of.77–.95) and excellent test–retest reliability (Spearman rho of.73–.96) with a significant inverse small correlation with Baecke Habitual Physical Activity Questionnaire indexes. The P-BPAQ-MI successfully discriminated between individuals with different assistive devices and sex. Community Built Environment barriers were the most prevalent and severe. Conclusions: The P-BPAQ-MI is a valid and reliable instrument to assess the PA barriers of people with physical disability. The community barriers were the most frequently reported obstacles to PA.
