Turkish validity and reliability of the patient satisfaction scale in physiotherapy for patients with musculoskeletal pain.

Abstract

Patient satisfaction is a key point in evaluating the quality of physiotherapy services. The aim of this study was to determine the Turkish language validity and reliability of the Patient Satisfaction Scale in Physiotherapy (PSSP). The study included 168 participants, aged 18-74 years, with musculoskeletal pain. The PSSP, which comprises 14 items in the four sub-dimensions of treatment, admission, logistics and general satisfaction, was applied to all participants. Structural validity was assessed using the principal components method with varimax rotation. Internal consistency and the intraclass correlation coefficient (ICC) were used for the reliability analysis. The Patient Satisfaction Scale for Physical Therapy Outpatient Clinics (PCCPTO) was used to assess concurrent validity. The participants comprised of 71% females and 29% males with a mean age of 41.9 ± 14.9 years. The sampling competency index was 0.874. The Turkish version of the scale was found to be perfectly reliable (Cronbach's alpha reliability coefficient = 0.922). Internal consistency ranged from 0.762 to 0.904 in the subscales. Factor analysis revealed that the 14-item scale had four factors explaining 75.59% of the total variance. Floor and ceiling effects were not determined. Concurrent validity analysis showed a strong correlation between the PSSP and PCCPTO (r= 0.78; p< 0.0005). The Turkish version of the PSSP is a valid, reliable and easily applicable measure.
