Abstract
Background/aim: Current clinical guidelines recommend to use both clinical and self-reported measurements for evaluation of chronicneck pain. Among the self-reported outcomes, Neck disability index and patient-specific functional scale are the most widely usedand recommended instruments. The purpose of our study was to determine the test-retest reliability and validity of patient-specificfunctional scale which was not validated in Turkish language previously.Materials and methods: Translation and adaptation process had conducted according to the Beaton et al. Sociodemographic data,Turkish version of patient-specific functional scale and neck disability index were recorded at the initial assessment. Retest assessmentwas produced for reliability analyses and intraclass correlation coefficient (ICC3,2) was determined. The correlations between patientspecific functional scale and neck disability index and hypothesis testing were examined for the convergent and construct validityanalysis.Results: The final form was completed by 110 chronic neck pain patients (Male: 33; mean ages: 43.13 ± 13.75 years, Female: 77; meanages: 44.45 ± 14.38). Test-retest reliability of patient-specific functional scale was found good level (ICC: 0.85). The relationship betweenpatient-specific functional scale and neck disability index was found moderate level (P < 0.05, rho: –0.578). The median score of PSFS-Tin the low disability group was significantly higher than the high disability group in the hypothesis testing of construct validity (P
