Methods: This research was a multicenter cross-sectional and repeated measure study. The cultural adaptation process was conducted according to an accepted international guideline. A total of 197 Persian-speaking individuals with LLA were recruited to investigate the reliability and validity of the PASIPD. Reliability analyses were assessed by Cronbach α and the Pearson product-moment correlation coefficient. The Association between the PASIPD scores and the prosthetic limb user survey of mobility scores was examined to evaluate the convergent validity of the PASIPD. Known-groups validity was assessed based on sex, amputation causes, and amputation levels. Results: The PASIPD had an acceptable internal uniformity (the Cronbach α of 0.68) and test-retest reproducibility (r=0.70). There was a small correlation between the PASIPD and prosthetic limb user mobility survey (r=0.26; P<0.001). Some items of PASIPD could discriminate individuals with different causes of amputation and sex. Factor analysis extracted four main factors that explained 65.4% of the variance. Discussion: The Persian version of the PASIPD has acceptable reliability and validity for assessing the physical activity of persons with LLAs.
