“…Test-retest reliability was examined using ICCs. ICCs of the tool were >0.80, demonstrating good test-retest reliability for the scale, which is similar to other studies reporting psychometric properties of the CNFDS [ 6 20 ]. Our results show that the CNFDS has acceptable interobserver reliability; however, it was not investigated in other studies.…”

“…The results indicate that the Persian version of the CNFDS is a valid and reliable instrument for measuring disability in patients with CSM. The measurements were consistent and reproducible, with good discriminative properties, and was comparable with versions in other languages [ 6 19 20 21 ].…”

“…It is a self-administered questionnaire, originally developed in Denmark [ 6 ], and is easily understood by patients [ 8 ]. It has been translated into Polish, Turkish, and French [ 19 20 21 ] and the entire questionnaire can be completed in <10 minutes [ 6 ]. Psychometric studies could help clinicians and researchers worldwide to carry out similar studies and compare the results.…”

Study DesignCross-sectional.PurposeTo translate and validate the Iranian version of the Copenhagen Neck Functional Disability Scale (CNFDS).Overview of LiteratureInstruments measuring patient-reported outcomes should satisfy certain psychometric properties.MethodsNinety-three cases of cervical spondylotic myelopathy were entered into the study and completed the CNFDS pre and postoperatively at the 6 month follow-up. The modified Japanese Orthopedic Association Score was also completed. The internal consistency, test-retest, convergent validity, construct validity (item scale correlation), and responsiveness to change were assessed.ResultsMean age of the patients was 54.3 years (standard deviation, 8.9). The Cronbach α coefficient was satisfactory (α=0.84). Test-retest reliability as assessed by the intraclass correlation coefficient analysis was 0.95 (95% confidence interval, 0.92-0.98). The modified Japanese Orthopedic Association score correlated strongly with the CNFDS score, lending support to its good convergent validity (r=-0.80; p<0.001). Additionally, the correlation of each item with its hypothesized domain on the CNFDS was acceptable, suggesting that the items had a substantial relationship with their own domains. These results also indicate that the instrument was responsive to change (p<0.0001).ConclusionsThe findings suggest that the Iranian version of the CNFDS is a valid measure to assess functionality, social interaction, and pain among patients with cervical spondylotic myelopathy.

“…There are several relevant questionnaires in current literature for evaluating the pain and the disability associated with the neck pain. The neck outcome score, the fremantle neck awareness questionnaire, the Copenhagen neck functional disability scale, neck bournemouth questionnaire, and neck disability index were translated and validated before into Turkish language [7][8][9][10][11]. However, the current guidelines and systematic reviews have mostly recommended neck disability index (NDI) and the patient-specific functional scale (PSFS) in the assessment process [2,6].…”

Background/aim: Current clinical guidelines recommend to use both clinical and self-reported measurements for evaluation of chronic neck pain. Among the self-reported outcomes, Neck disability index and patient-specific functional scale are the most widely used and recommended instruments. The purpose of our study was to determine the test-retest reliability and validity of patient-specific functional 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 assessment was produced for reliability analyses and intraclass correlation coefficient (ICC 3,2) was determined. The correlations between patientspecific functional scale and neck disability index and hypothesis testing were examined for the convergent and construct validity analysis. Results: The final form was completed by 110 chronic neck pain patients (Male: 33; mean ages: 43.13 ± 13.75 years, Female: 77; mean ages: 44.45 ± 14.38). Test-retest reliability of patient-specific functional scale was found good level (ICC: 0.85). The relationship between patient-specific functional scale and neck disability index was found moderate level (P < 0.05, rho:-0.578). The median score of PSFS-T in the low disability group was significantly higher than the high disability group in the hypothesis testing of construct validity (P < 0.001). Conclusion: The Turkish version of the patient-specific functional scale is a valid and reliable scale for evaluating functional status in patients with chronic neck pain.

“…What is expected from scales is that they measure the status of individuals suffering from neck pain objectively and functionally and are sensitive to minor changes in individuals. The Copenhagen Neck Functional Disability Scale, Neck Pain and Disability Scale, and Neck Disability Index (NDI) are major questionnaires used for functional evaluation of neck pain in Turkey [5][6][7]. Among these questionnaires, the NDI is the most widely preferred [8,9].…”

Background/aim: This study aims to determine the validity and reliability of the Turkish version of the Neck OutcOme Score (NOOS). Materials and methods: Two hundred eight patients suffering from nonspecific neck pain participated in the study. Test-retest reliability and internal consistency were assessed using intraclass correlation coefficients (2, 1) and Cronbach's alpha, respectively. The dimensionality was investigated with the factor analysis. The construct validity was determined by testing whether the hypothesis of correlations between NOOS subscales, Short Form-36 subscales, and the Neck Disability Index were met using Spearman's rank correlation coefficient. Ceiling/floor effects and measurement error were tested as well. Results: The intraclass correlation coefficient results varied between 0.721 and 0.844. Cronbach's alpha values of the subscale were found to be between 0.847 and 0.916 in the internal consistency analysis. The factor analysis showed that the questionnaire has five factors. Floor/ceiling effects were considered not to be present. Conclusion: It was found that the Turkish version of the NOOS is valid and reliable.
