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.
