Description
Carlos Luques Fonseca and colleagues re-examine in 2026 whether the questionnaires used for chronic low back pain actually register change well. Their secondary analysis of a randomized trial split patients into active and placebo groups and tracked scores at baseline, after treatment, and at follow-up. Internal responsiveness, meaning change within groups, was judged by effect sizes, while external responsiveness tested whether scores could spot patients who truly felt better.
Pain and quality-of-life scales showed large internal effects, so the tools detect group-level movement easily. Yet every instrument scored below 0.70 on the curve test for telling apart individual improvers, and the Bournemouth Questionnaire did best of a weak field. The authors recommend combining measures rather than trusting any single score for decisions about one patient.
