Introduction The importance of use of patient-reported outcome measurements (PROMs) in spine care has been previously widely reported, especially for lumbar conditions. One of the main clinicometric properties of a PROM is the responsiveness showing its discriminative ability between good and poor global treatment outcomes. Very limited data about the responsiveness of different cervical PROMs have been published so far. The aim of the study was to analyze the responsiveness of three validated cervical PROMs on a prospective clinical cohort. Material and Methods A total of 100 patients with degenerative cervical spinal disorders were recruited into the study. The patients filled out the cross-culturally adapted Hungarian versions of the Neck Disability Index (NDI), the Neck Pain and Disability Scale (NPAD), and the Core Outcome Measures Index for neck (COMI). Test–retest method was applied to assess the validity and reliability dimensions of the questionnaires. Patients completed the questionnaires 3 months after the surgical or nonsurgical treatment. Two different five-point Likert scales on global treatment outcome were used to determine the “good” and “poor” results. The receiver operating characteristics (ROC) method was used to evaluate the discriminative ability of the given change score relative to the outcome (c-index). SPSS 20.0 statistical program package was used for the analyses where p
