The Neck Disability Index is the most frequently evaluated question naire and shows positive results for internal consistency , content validity , structural validity , hypothesis testing , and responsiveness , but a negative result for reliability .
The other question naires show positive results , but the evidence for each measurement property is mostly limited , and at least 50 % of the information on measurement properties per question naire is lacking .
Purpose To critically appraise and compare the measurement properties of the original versions of  neck-specific question naires .
The Core Outcomes for Neck Pain: Validation of a New Outcome Measure
Study Design . Patients enrolled in a r and omized controlled trial were asked to complete various question naires , which were then compared to establish validity for a new neck pain question naire . Objectives . To vali date a new and brief outcome measure for use with patients with mechanical neck pain . Summary of Background Data . Neck pain is a very common problem and one that clinicians will be required to treat with some regularity . In today ’s climate of evidence -based practice and the need to quantify and justify clinical intervention , a quick and easy method to evaluate progress is required . Such a measure has already been produced for those experiencing back pain , but as yet , there is no such measure for neck pain and this needs to be addressed . Methods . The  back pain measure  was adapted to enable its use with patients with neck pain .  Repeatability was assessed by using a 1-week test/retest on 104 patients who were enrolled in a neck pain trial .  Validity was assessed by comparing the new question naire against other already well vali date d measures ( i.e. , the Neck Disability Index and a Visual Analogue Scale for pain ) with 133 patients . Results . The test/retest showed excellent repeatability with high intraclass correlations and P < 0.001 for each question tested . The Core Neck Pain Question naire also showed good validity , giving close agreement to the other comparison measures . Conclusion . The short Core Neck Pain Question naire has been demonstrated to be repeatable and valid as a brief outcome measure for use with patients with mechanical neck pain
