The purpose of this study was to establish reliability and validity of the Northwick Park Neck Pain Questionnaire (NPQ) translated into Korean for neck pain patients. Sixty-two subjects (35 males, 27 females) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that included pain intensity, sleeping, sensory at night, duration of symptoms, carrying, reading and watching television, working, social activities, and driving. Reliability was determined by intraclass correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NPQ scores to the Visual Analog Scale (VAS) score. Test-retest reliability of the translated versions of the NPQ was good ICC(2,1)=.83 (95%CI=.85-.95). Cronbach's alpha value for NPQ was found to be .87 and this was statistically significant (p<.05). The criterion-related validity coefficients was .75 (p<'Ol). We concluded that the Korean version NPQ was shown to be a reliable and valid instrument for the assessment of neck pain.
