Randomized Controlled Trial
Validity evidence for the back beliefs questionnaire in the general population.
Despite common usage of the back beliefs questionnaire (BBQ) in a variety of studies, important validity evidence is missing. The objective of this study was to examine the validity of the BBQ in the general population. ⋯ This study provides strong validity evidence supporting the current structure and scoring of the BBQ. In addition, construct validity was evidenced by the behaviour of BBQ scores in a manner congruent with our hypotheses, further supporting use of the BBQ in the general population.
