Translation, Cross-Cultural Adaptation, Reliability and Construct Validation of Patient Satisfaction with the Physical Therapy Questionnaire in Persian

Abstract

Background: This methodological study evaluated the psychometric properties of the Persian version of the questionnaire for patients' satisfaction with physical therapy. Methods: The Persian version of this questionnaire was prepared through forward and backward translation. Its reliability was examined by the intraclass correlation coefficient (ICC) and Cronbach's alpha. Structural validity was evaluated through confirmatory factor analysis and assessing the correlation between the score of the questionnaire with the visual analog score (VAS) and global rating of change (GRC) scale. The correlation of the questionnaire was checked with PTPSQ. Results: A total of 297 patients with musculoskeletal disorders at public physical therapy centers in Kerman, Iran, participated in this study and 40 participants, five to seven days later, answered the questionnaire again. Cronbach's alpha coefficient was 0.95 and ICC was 0.88. The confirmatory factor analysis confirmed the four-factor solution. The correlation coefficients of the total score of the questionnaire with the VAS and GRC scores were -0.24 (P = 0.0001) and -0.32 (P = 0.0001), respectively. The correlation of this questionnaire with the other physiotherapy satisfaction questionnaire was good. Conclusions: The Persian version of the 14 items on patient satisfaction with physical therapy questionnaire exhibited acceptable reliability and validity.

Level Of Patient’s Satisfaction with Physical Therapy Services in Public and Private Hospitals

“…This questionnaire includes items on external factors (items 1-3), internal factors (items 4-10), and two global measures of satisfaction (items 11-12), with patients rating each item on a scale of 1 to 5. Notably, items 4 and 7 are scored in reverse to ensure positive alignment (18). The validity and reliability of the MRPS were reinforced by a study in 2019, yielding a Cronbach's alpha coefficient of 0.95 (19).…”

Measurement Properties of Physical Therapy Patient Satisfaction Questionnaire (PTPSQ) in an Iranian Musculoskeletal Population

“…It has 34 items with four subscales of enhancers, detractors, location, and cost, which all demonstrated the different domains of patient satisfaction [20,21]. A 14-item questionnaire that was developed by Monnin and Perneger [22] is one of the other tools that was translated into Persian [23]. It assesses three aspects of treatment, admission, and logistics in different clinical settings [22].…”
