Abstract

Background: Valid and reliable tools are required to measure patient satisfaction with physical therapy care. The aim of this study was to translate the MedRisk instrument for measuring patient satisfaction with physical therapy care (MRPS) into Persian language and to evaluate its measurement properties. Methods: A cross-sectional and prospective validation study design was adopted. The development of the Persian MRPS (MRPSp) followed the standard guidelines with “forward”–“backward” translation, consensus agreement of expert panel, and pilot testing. The final MRPSp was evaluated for reliability and validity. Results: A total of 114 patients (mean age 52.14 years, 72 females) participated in this study. The patients’ satisfaction was high as reflected in the ceiling effect (25.4%). The overall Cronbach’s α was 0.91. Corrected item-total correlations ranged from 0.22 to 0.88. Principal component analysis suggested a 7-item “internal” factor (alpha = 0.95) and a 3-item “external” factor (alpha = 0.74). The correlations of factors with two global measures of satisfaction were significant ranging from 0.247 to 0.789. Individual items of MRPSp had significant positive correlations with two global measures (r = 0.233–0.736). The standard error of measurement was between 0.97 and 2.14. The smallest detectable change was between 2.7 and 5.93. Conclusion: The Persian version of the MRPS is a two-factor reliable and valid instrument for measuring patient satisfaction with physical therapy care. © 2020 Taylor & Francis Group, LLC.
