The Validity and Reliability of the Turkish Version of the Disablement in the Physically Active Scale

Abstract

Context: The Disablement in the Physically Active Scale (DPAS) was recently developed to evaluate the disability process and health-related quality of life. The aim of this study was to investigate the validity and reliability of the Turkish version of the DPAS in physically active individuals with musculoskeletal injury. Methods: The study sample comprised 64 physically active individuals with musculoskeletal injury aged 16–40 years. The DPAS was translated into Turkish according to the guidelines for cross-cultural adaptation. Short Form-36 was used concurrently to test the construct validity. The test–retest reliability of the Turkish version of the scale assessed by intraclass correlation coefficient and Cronbach α was calculated for internal consistency. Results: Confirmatory factor analysis carried out on the Turkish version of the DPAS was confirmed. Cronbach α was calculated to be .946. The intraclass correlation coefficients ranged between .593 and .924 (P < .001). The Turkish version of the scale showed significant correlations with domains of the Short Form-36 (P < .05). When the sensitivity of the study was evaluated, the highest correlation was found between DPAS total score and impairments (r = .906, P = .001), and the lowest correlation was between DPAS total score and quality of life (r = .637, P = .001). Conclusion: The Turkish version of the DPAS is a reliable, valid, and practical tool. The Turkish version of the DPAS can be used by health professionals to understand quality of life, the disability process, and activity limitations in Turkish-speaking physically active people after musculoskeletal injuries.
