Abstract Background The Low Physical Activity Questionnaire (LoPAQ) was specifically developed to measure the low activity level observed in extremely inactive hemodialysis (HD) patients. This study aims to evaluate reliability and validity of Persian version of the LoPAQ. Methods This study was a cross sectional study, conducted in three HD centers in Iran. The LoPAQ was translated into Persian. After cultural adaptions, it was filled out by 120 HD patiens. Convergent validity, was evaluated by calculating the correlations among the Persian version of the LoPAQ and Persian version of the Community Healthy Adults Model Program for Seniors (CHAMPS) questionnaire, physical function scale of the SF-36 and physical function (Short Physical Performance Battery (SPPB) test) using Spearman’s correlation coefficients. The test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Results In total, 109 patients completed all of the questionnaires, took part in physical performance tests and had valid data. Their mean age was 64 ± 11 years, with a dialysis history of 31 ± 10 months. For total calories, there was a strong correlation between the Persian version of the LoPAQ and CHAMPS-measured physical activity (rho = 0.85, p < 0.001). In addition, the higher physical activity level reported by Persian version of the LoPAQ was also correlated with better self-reported physical function (rho = 0.7, p < 0.001) and better physical performance (rho = 0.67, p < 0.001). The ICC ranged from 0.65 to 0.78, indicating strong reliability. Conclusion The assessment of the validity and reliability of the Persian version of the questionnaire confirmed its suitability for evaluating the level of physical activity. Trial registration ClinicalTrials.gov Identifier: NCT05930964, Registered on 05/07/2023. Registered trial name: Validity and Reliability of Persian Version of Low Physical Activity Questionnaire (LoPAQ).
