OBJECTIVE: To validate a French version of the Roland-Morris Disability
Questionnaire (RMDQ) in patients with chronic low back pain (LBP). MATERIAL AND
METHODS: Fifty-eight patients due to participate in a functional rehabilitation
programme for chronic low back pain were included prospectively. The RMDQ, the
Quebec Back Pain Disability Scale (QBPDS) and the "daily activities" subscale of
the Dallas Pain Questionnaire (DPQ) were administered. The RMDQ was assessed for
internal consistency, reliability, criterion validity and sensitivity to change.
RESULTS: Cronbach's alpha for the RMDQ was 0.84. The intraclass correlation
coefficient [95% confidence interval] was 0.89 [0.83-0.93]. The RMDQ score was
correlated with the QBPDS score (r=0.713) and the DPQ's "daily activities"
subscore (r=0.514). The results of assessments before and after functional
rehabilitation showed that the French version of the RMDQ had very high
sensitivity to change (effect size: 1.49) and was more sensitive than the QBPDS
and the DPQ's "daily activities" subscore. CONCLUSIONS: Our study validated the
French version of the RMDQ in patients suffering from chronic low back pain.
Furthermore, we highlighted the questionnaire's very high sensitivity to change.
