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 Bournemouth Questionnaire: a short-form comprehensive outcome measure. II. Psychometric properties in neck pain patients.
OBJECTIVE To modify an existing outcome measure ( Bournemouth Question naire [ BQ ] ) for use in patients with nonspecific neck pain and test its psychometric properties . DESIGN Prospect i ve longitudinal study in which the question naire was administered on 3 occasions ( pretreatment , retest , and posttreatment ) . SETTING Anglo-European College of Chiropractic outpatient clinic and 8 field chiropractic practice s. METHOD Seven core items relating to the biopsychosocial model of pain were included in the original question naire ( back BQ ) . The wording of one of these items ( disability in activities of daily living ) was modified to include activities likely to be affected by neck pain . Testing of the neck BQ was carried out in 102 patients with nonspecific neck pain . RESULTS The instrument demonstrated high internal consistency on 3 administrations ( Cronbach 's alpha = 0.87 , 0.91 , 0.92 ) . All 7 items were retained on the basis that they each significantly contributed to the total score ( item-corrected total score correlations > 0.43 ) and to the instrument 's responsiveness to clinical change ( item change-corrected total change score correlations > 0.42 ) . The instrument was reliable in test-retest administrations in stable subjects ( ICC = 0.65 ) . The instrument demonstrated acceptable construct validity and longitudinal construct validity with established external measures . The treatment effect size of the instrument was found to be high ( 1.67 ) . CONCLUSION The neck BQ covers the salient dimensions of the biopsychosocial model of pain , is quick and easy to complete , and has been shown to be reliable , valid , and responsive to clinical ly significant change in patients with nonspecific neck pain . Its use as an outcome measure in clinical trials and outcomes research is recommended
