Abstract

Background: Neck pain is a highly prevalent sumptom resulting in major disability. Standard scales for measuring disability in patients with neck pain have a pivotal role in research and clinical settings. Neck Disability Index (NDI) is a valid and reliable tool, designed to measure disability in activities of daily living due to neck pain. The purpose of our study was the translation and validation of the NDI in a Greek population with neck complaints seeking primary care. Methods: Based on international standards, the translation strategy comprised forward translations, reconciliation, backward translation and pre-testing steps. The validation procedure concerned the exploration of internal consistency (Cronbach alpha), test-retest reliability (Intraclass Correlation Coefficient), construct validity (Exploratory Factor Analysis) and responsiveness (Spearman Correlation Coefficient, Standard Error of Measurement and Minimal Detectable Change) of the questionnaire. Data quality was also assessed through completeness of collected data and floor/ceiling effects. Results: The translation procedure resulted in the Greek modified version of the NDI. The latter was culturally adapted through the pre-testing phase. The validation procedure raised a large amount of missing data, which were assessed with two methods. Factor analysis yielded one factor with Eigen value 4,48 explaining 44,77% of variance. Cronbach alpha was calculated as 0,85, which was interpreted as good internal consistency. ICC was found Public Health & Health Care Management to be 0,93 (95% CI 0,84-0,97) which was considered as very good test-retest reliability. Spearman correlation coefficient was found to be 0,3 (P=0,02) which revealed some relation between change score in the NDI and Global Rating of Change (GROC). The SEM and MDC were calculated as 0,64 and 1,78 respectively. Floor or ceiling effects were not observed. Conclusions: The Greek version of the NDI measures disability due to neck pain in a reliable, valid and responsive manner. It is considered a useful tool for research and clinical settings in Primary Health Care.
