dc.description.abstractOBJECTIVE: To develop a valid and reliable functional disability scale for chronic low back pain (CLBP). METHODS: Inpatients and outpatients suffering from low back pain (LBP) for at least 3 months were selected randomly. Patients with inflammatory LBP were not recruited. Interrater reliability and Cronbach's alpha were examined. Face, content, convergent and divergent validities were investigated. Factor Analysis and pearson's correlation coefficients (r) were performed. RESULTS: 112 patients (71 females) with a mean age of 39.93 (SD: 12.92) answered the 66 questions on the provisional scale. Elimination left 18 daily activity questions. The interrater reliability of the scale was 0.79 and Cronbach's alpha was 0.90. Face and content validities were determined. It showed good convergence with the Quebec Back Pain Disability Scale (r: 0.82), the Oswestry Disability Index (r: 0.76), Waddell's Functional Index (r: 0.68), and the Visual Analog Scale of Handicap (VAS-handicap) (r: 0.49) The scale showed no significant or fair relationship (divergence) with VAS-lumbar, VAS-radicular, Beck Depression Inventory, morning stiffness, night pain, finger tip-ground distance, radicular pain duration, or modified Schober's index. The scale had two main factors. First represents activities implicating forward bending and second represents standing activities. CONCLUSION: A practical functional disability scale for CLBP was developed and validated.
