Abstract
This study aimed to translate and psychometrically validate the Neck Outcome Score (NOOS) in the Polish population according to the recommendations of the American Academy of Orthopedic Surgeons Participants completed online version of the NOOS, Neck Disability Index (NDI), and Visual Analogue Scale (VAS) for pain assessment (23 November 2021-9 April 2022). The questionnaires were completed by 57 women and 32 men with cervical spine ailments. A retest was performed after 48 h. The analysis confirmed the high internal consistency (Cronbach's alpha of 0.95) of the Polish NOOS. No floor/ceiling effects were observed. The Polish NOOS showed a significant Spearman's coefficient correlation with NDI (0.87; p < 0.001) and VAS (0.79; p < 0.001). The intraclass correlation coefficient (ICC) for the test-retest was found to be high (0.97). The Polish NOOS can be used for clinical and research purposes as an equivalent to the original version.

Psychometric validation of the Polish version of the Central Sensitization Inventory in subjects with chronic spinal pain. BMC Neurol 2021; 21:483. [PMID: 34893020 PMCID: PMC8665486 DOI: 10.1186/s12883-021-02510-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Accepted: 11/30/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Central sensitization is an amplification of neuronal signaling within the central nervous system. The Central Sensitization Inventory was introduced in 2012. A Polish version of the CSI (CSI-Pol) was developed in 2019, but it was not psychometrically validated. The aim of this study was to validate the CSI-Pol in a sample of Polish-speaking patients with chronic spinal pain and compare them with a group of healthy control subjects. METHODS The CSI-Pol was administered to 151 patients with chronic spinal pain recruited from two centers. It was re-administered 7 days later. The psychometric properties were then evaluated, including test-retest reliability, construct validity, factor structure and internal consistency. We correlated the CSI-Pol with functional scales, depression and social support scales and compared CSI-Pol scores in the clinical subjects with 30 healthy control subjects recruited from medical staff and their families. RESULTS The CSI-Pol demonstrated excellent internal consistency (Cronbach's α =0,933) and test-retest reliability (Intraclass Correlation Coefficients - ICC =0.96), as well as significant positive associations with other patient-reported scales, including the Neck Disability Index (r = 0.593), Revised Oswestry Low Back Pain Disability Questionnaire (r = 0.422), and other measures of functional and depressive states. An exploratory factor analysis resulted in a 4-factor model. CSI-Pol scores in the clinical sample (35.27 ± 17.25) were significantly higher than the control sample (23.3 ± 8.9). CONCLUSION The results of this study suggest that the CSI-Pol may be a useful clinical tool for assessing central sensitization related symptoms and guiding appropriate treatment in Polish-speaking patients with spinal pain.

Reliability and Validity of Cross Culturally Adapted Punjabi Version of NDI (NDI-P) in Patients with Neck Pain: A Psychometric Analysis. Indian J Orthop 2021; 55:918-924. [PMID: 34194648 PMCID: PMC8192611 DOI: 10.1007/s43465-020-00280-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 09/29/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Neck disability index (NDI) is one of the commonest patient-reported outcome measures used to evaluate disability related to neck pain. Its application to non-English-speaking Punjabi population is limited as a validated and cross-culturally adapted Punjabi version of NDI is not available. The purpose of the study was to analyze the psychometric properties of Punjabi version of neck disability index (NDI-P) in patients with neck pain. MATERIALS AND METHODS The translation and cross-cultural adaptation of Punjabi version of NDI was done according to well-recommended guidelines. The pre-final version was tested on a set of 15 patients and suitable modifications were made. The final version was administered to 100 patients with neck pain of more than 2 weeks duration. Psychometric properties comprising internal consistency, test-re-test reliability, construct validity and factorial structure of the questionnaire were determined. RESULTS The developed NDI-P showed excellent internal consistency (Chronbach alpha of NDI-P is 0.87), test-re-test reliability (ICC 0.840) and construct validity (Spearman correlation coefficient with VAS 0.547). Factor analysis proved the questionnaire to be having a 2-factor structure with a total variance of 56.58%. CONCLUSION NDI (P) is a reliable and valid instrument for measurement of disability related to neck pain in Punjabi population. It can be used both in research and clinical care settings in future.

Abstract
PURPOSE The purpose of this study was a cross-cultural adaptation of the Spine Functional Index to produce a Polish version (SFI-PL). Further, the psychometric properties were evaluated with standardized criteria patient reported outcome measures (PROMs) in a symptomatic Polish spine population. METHODS Linguistic adaptation complied with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines to produce the SFI-PL. Subjects with spine conditions, all areas and multi-area, were recruited from a Polish Specialist Hospital (n = 225, age = 45.7 ± 16.0 years, range 18-87, female = 60%, symptoms duration = 13.93 ± 27.56 weeks, range 5-84). Baseline internal consistency, reliability and validity were examined and included the SFI-PL, Oswestry Disability Index (ODI), Neck Disability Index (NDI), EuroQol 5 Dimensions, 5-level version (EQ-5D-5L) and an 11-point pain Numerical Rating Scale (NRS) with retest at 3-7 days (= 5 days). Practicality for readability was considered within the face and content validity and completion and scoring time calculated. RESULTS Statistical analysis showed excellent internal consistency (α = 0.90) and high test-retest reliability (ICC = 0.98). The error score was determined with the SEM = 3.14 (MDC 90% CI = 7.33%). The construct validity analysis demonstrated strong correlations between the SFI-PL, the NDI (r = 0.73) and the ODI (r = 0.82); moderate with the EQ index value (0.70) and EQ-VAS (r = 0.56). Time to complete (229 s) and score (27 s) were determined. CONCLUSIONS The SFI-PL is a psychometrically sound PROM for Polish-speaking patients with spine conditions. The results support previous findings from the original-English and six other language versions for internal consistency, reliability, measurement error and validity.

Abstract
OBJECTIVES The problem of spinal pain among nurses and lack of compliance with workplace ergonomy is increasing. The study aimed to assess the pressure pain threshold (PPT) at the cervical and lumbar spine in nursing staff. METHODS The sample of this prospective and observational study consisted of 30 female nurses with a mean age of 38.6 ± 11.1 years. The standardized Oswestry (ODI) and the Neck Disability Index (NDI) were used, as well as the Authors' Designed Questionnaire (ADQ) was used to assess compliance with ergonomic principles. The PPT analysis using a computerized pressure algometer (CPA) was performed to examine the level of PPT. RESULTS A mild disability was found in 56% of nurses (NDI and ODI). A value of <4 kg/cm2 (CPA), indicating musculoskeletal overload was observed in 57% of subjects. Also, 60% of nurses work with a lying patient; 73.4% grabs the patient's armpits while transferring in bed; 16.7% never adjusts the height of the bed, and only 13.4% choose specialist footwear for work. There is a correlation between PPT values for trapezius and erector spinae muscles on the same side of the body in nurses with mild and moderate disability (P < .05). CONCLUSIONS Pain complaints are associated with lower PPT of trapezius and erector spinae muscles and asymmetry of muscle tension. Also, it was noted that the lack of implementation of ergonomic principles by nursing staff affects their degree of disability.

Abstract
OBJECTIVE The purpose of this systematic review was to critically appraise and synthesise the psychometric properties of Global Rating of Change (GROC) scales for assessment of patients with neck pain. DESIGN Systematic review. DATA SOURCES A search was performed in four databases (MEDLINE, EMBASE, CINAHL, SCOPUS) until February 2019. DATA EXTRACTION AND SYNTHESIS Eligible articles were appraised using Consensus-based Standards for the selection of health Measurement Instruments checklist and the Quality Appraisal for Clinical Measurement Research Reports Evaluation Form. RESULTS The search obtained 16 eligible studies and included in total 1533 patients with neck pain. Test-retest reliability of global perceived effect (GPE) was very high (intraclass correlation coefficient=0.80 to 0.92) for patients with whiplash. Pooled data of Pearson's r indicated that GROC scores were moderately correlated with neck disability change scores (0.53, 95% CI: 0.47 to 0.59). Pooled data of Spearman's correlations indicated that GROC scores were moderately correlated with neck disability change scores (0.56, 95% CI: 0.41 to 0.68). CONCLUSIONS This study found excellent quality evidence of very good-to-excellent test-retest reliability of GPE for patients with whiplash-associated disorders. Evidence from very good-to-excellent quality studies found that GROC scores are moderately correlated to an external criterion patient-reported outcome measure evaluated pre-post treatment in patients with neck pain. No studies were found that addressed the optimal form of GROC scales for patients with neck disorders or compared the GROC to other options for single-item global assessment.

Abstract
BACKGROUND Patient-reported outcome measures can improve the management of patients with non-specific neck pain. The choice of measure greatly depends on its content and psychometric properties. Most questionnaires were developed for English-speaking people, and need to undergo cross-cultural validation for use in different language contexts. To help Italian clinicians select the most appropriate tool, we systematically reviewed the validated Italian-language outcome measures for non-specific neck pain, and analyzed their psychometric properties and clinical utility. METHODS The search was performed in MEDLINE, EMBASE, CINAHL, Scopus, Web of Science, and Cochrane Library. All articles published in English or Italian regarding the development, translation, or validation of patient-reported outcome measures available in the Italian language were included. Two reviewers independently selected the studies, extracted data, and assessed methodological quality using the COSMIN checklist. RESULTS Out of 4891articles screened, 66 were eligible. Overall, they were of poor or fair methodological quality. Four instruments measuring function and disability (Neck Disability Index, Neck Pain and Disability Scale, Neck Bournemouth Questionnaire, and Core Outcome Measures Index), and one measuring activity-related fear of movement (NeckPix©) were identified. Each scale showed some psychometric weaknesses or problems with functioning, and none emerged as a gold standard. CONCLUSIONS Several patient-reported outcome measures are now available for assessing Italian people with non-specific neck pain. While the Neck Disability Index is the one most widely used, the Neck Bournemouth Questionnaire appears the most promising tool from a psychometric point of view.

Abstract
This cross-sectional clinical study was designed to explore the relationships between family functioning, coping styles, and neck pain and neck disability. It was hypothesized that better family functioning and more effective coping styles would be associated with less pain and pain-related disability. It also was hypothesized that these relationships would be stronger in older people because they have fewer resources, more limited coping styles, and may depend more on their family for support. In this study, 88 women with chronic non-traumatic neck pain completed the Family Assessment Measure (FAM), Coping Inventory for Stressful Situations (CISS), Neck Disability Index (NDI), and a Visual-Analogue Scale (VAS) measuring the subjective intensity of neck pain. Zero-order and partial correlations and hierarchical stepwise regression were performed. CISS was not correlated with the NDI orVAS. Good family functioning was correlated with lower NDI and VAS scores. Age was found to moderate the relationship between the FAM and both NDI and VAS. This relationship was significant and positive in older patients, but non-significant in younger patients. It was concluded that better family functioning is associated with lower neck disability and pain intensity, especially in the case of older women suffering from non-traumatic neck pain.

Abstract
STUDY DESIGN Cross-cultural adaptation and psychometric testing. OBJECTIVE To perform a validated Russian translation and then to evaluate the validity and reliability of the Russian language version of the Neck Disability Index (NDI-RU). SUMMARY OF BACKGROUND DATA Neck pain is highly prevalent and can greatly affect daily activity. The Neck Disability Index (NDI) is the most frequently used scale for self-rating of disability due to neck pain. Its translated versions are applied in many countries. However, the Russian language version of the NDI has not been developed yet. METHODS Cross-cultural adaptation of the NDI-RU was performed according to established guidelines. Then, the NDI-RU was evaluated for content validity, concurrent criterion validity, internal consistency, test-retest reliability, factor structure, and minimum detectable change. RESULTS Two hundred thirty-two patients took part in the study in total: 109 in validity (39.5 ± 10 yr), 123 in reliability (38.4 ± 11 yr; 80 in the test-retest phase). A culturally valid translation was achieved. NDI-RU total scores were distributed normally. Floor/ceiling effects were absent. Good values of Cronbach α were obtained for each item (from 0.80 to 0.84) and for the total NDI-RU (0.83). A 2-factor solution was found for the NDI-RU. The average interitem correlation coefficient was 0.53. Intraclass correlation coefficients for test-retest reliability coefficients ranged from 0.65 to 0.92 for different items and 0.91 for the total NDI-RU. Moderate correlation (Spearman rs = 0.62; P < 0.05) was found between the NDI-RU total score and graphic rating scalepain score. Completion of the NDI-RU takes 3.6 ± 1 minutes. CONCLUSION The development of a Russian language version of the Neck Disability Index resulted in a valid, reliable instrument that can be used both in clinical practice and scientific investigations.

Abstract
STUDY DESIGN Systematic review of cross-cultural adaptation. OBJECTIVE To perform a systematic review of cross-cultural adaptations of the Neck Disability Index (NDI) and to give a critical assessment to improve its translation. SUMMARY OF BACKGROUND DATA The NDI is used to assess functional capacity and physical activity in patients with neck pain, but the quality of its cross-cultural adaptations has not been systematically reviewed. METHODS PubMed, Cochrane Library, and EMBASE were searched up through 2013 to identify studies of cross-cultural NDI adaptations. Search terms were "Neck Disability Index" or "NDI" and "cross-cultur*" or "cultur*" or "valid*" or "equivalence" or "transl*." Data were extracted and study quality was assessed. RESULTS Twenty-four different NDI versions were identified from 14 different languages/cultures. Most reported forward and back translation and pretesting, but sample size was a problem for most studies. The Cronbach α was generally acceptable, and 13 versions met the criterion of reliability by reporting an intraclass correlation coefficient of 0.70 or more, although some versions did not reach the minimal intraclass correlation coefficient. Eleven versions tested ceiling and floor effects, but only 1 Japanese version reported a floor effect. No study reported interpretability, and none provided the minimal important change or minimal important difference. CONCLUSION The Arabic, Italian, and Thai versions were of higher quality than the other versions according to the overall assessment of the 3 checklists. The Catalan, Chinese, Japanese, Korean, Thai, and Turkish versions need more research according to the Quality Criteria for Psychometric Properties of Health Status Questionnaire. Pretest sample size was not large enough in most cases. LEVEL OF EVIDENCE 1.

Abstract
BACKGROUND The Neck Disability Index (NDI) is the most commonly used outcome measure for neck pain. This study aimed to determine the psychometric properties of a German version of the NDI. Cross-cultural translation and psychometric testing of the NDI were performed. METHODS The 10-item NDI was translated into German and administered to 558 patients with chronic unspecific neck pain (Mean age 49.9 ± 11.4 years, 76% female). The factor structure and reliability of the NDI were assessed using factor analysis, Cronbach's alpha, split-half reliability (Spearman-Brown coefficient), and intra-class correlation (ICC2,1). To determine convergent validity, pain intensity (visual analog scale; VAS), pain on movement (VAS), and quality of life (Short Form 36 Health Survey Questionnaire; SF-36) were correlated with the NDI. Correlation with range of motion and sensitivity to change were also assessed in a subsample of 49 patients. RESULTS The mean NDI score was 32.75 ± 13.09. Factor analysis revealed a single factor that explained 39.8% of the variance. Cronbach's alpha was 0.81; Spearman-Brown coefficient was 0.80; and intra-class correlation was 0.81 (95% confidence interval = 0.78, 0.83). Significant correlations were found for pain intensity (r = 0.22, p < 0.01), pain on movement (r = 0.39, p < 0.01), quality of life (r = -0.30 to -0.45, p < 0.01), and range of motion (r = -0.34, p = 0.02). Patients who reported global improvement of health after an exercise or yoga intervention showed a higher decrease on the NDI than patients who reported no global improvement (p < 0.01). CONCLUSIONS The German version of the NDI has a comparable factor structure as the original version, acceptable psychometric properties, and is sensitive to change after physical activity. Neck disability is associated with other measures of neck pain.
