Purpose: To assess overall reliability and validity of a neck-specific questionnaire, the Profile Fitness Mapping neck questionnaire (ProFitMap-neck), on three chronic neck pain groups. Method: Participating groups were as follows: whiplash associated disorders, inpatient care (IP-WAD, n = 127); nonspecific neck pain, inpatient care (IP-NS, n = 83) and nonspecific neck pain subjects (non-IP-NS, n  = 104). All groups answered the ProFitMap-neck and the SF-36, whereas non-IP-NS also answered the Neck Disability Index (NDI) and the Functional Self-Efficacy Scale (SES). Internal consistency, test–retest reliability and components of convergent construct, face and content validity were determined for the ProFitMap-neck. Results: The ProFitMap-neck showed good internal consistency in all three groups, and ICC test–retest reliability (0.80–0.91). Good correlation (0.66–0.78) and highest agreement was reached with NDI. According to the International Classification of Functioning, Disability and Health, the symptom scale of the ProFitMap-neck was mainly classified to the domain of impairments–body functions, and the functional limitation scale to the activity limitation domain. Conclusion: The results indicate that the ProFitMap-neck is valid for measuring symptoms and functional limitations in people with chronic neck pain. The combination of a composite total score of symptoms and function as well as separate scores of each domain makes ProFitMap-neck suitable for research as well as in clinical practice.

Implications for Rehabilitation

• The ProFitMap-neck can be used as a valid self-assessment tool for measuring symptoms and functional limitations in people belonging to the most prevalent categories of neck pain.

• The combination of the symptom and functional limitation questionnaire scores in a total score can be used for an overall clinical judgment.
