Abstract

Purpose: The objective of this study is to create a Turkish adaptation of the Plantar Fasciitis Pain/Disability Scale (PFPS) and to evaluate its construct validity and internal consistency. Method:The Turkish version of the PFPS was developed in accordance with the established translation and back-translation processes. The translated version of the scale was administered to a sample of 138 patients diagnosed with plantar fasciitis (PF). Validity was also evaluated using the Turkish version of the Foot Function Index (FFI). The test-retest reliability of the PFPS was determined by administering the scale to 138 patients on two occasions. Findings:The test-retest reliability was investigated through the utilisation of a paired t-test, an intraclass correlation coefficient analysis (ICC), and a Cronbach's alpha score. Construct validity was investigated through the utilisation of Pearson's correlation analysis. The Turkish version of the PFPS exhibited high internal consistency and test-retest reliability (Cronbach's alpha = 0.844, ICC = 0.997), as well as good construct validity, demonstrating a significant correlation with the FFI (p <.001). Furthermore, a notable difference was observed between the lower and upper 27% groups (p = 0.000). Conclusion: The Turkish version of the PFPS has been demonstrated to be a reliable, valid, and responsive instrument for patients with PF. Nevertheless, further studies involving a greater number of age groups, genders and languages are required to confirm the responsiveness of the PFPS and to provide further evidence of its full validity.
