STUDY DESIGN: In a prospective interventional study, problems with performance were evaluated in 101 consecutive patients with chronic low-back pain for more than 12 months, before and after participation in an outpatient-based multidisciplinary pain management program in Mansfield, United Kingdom. OBJECTIVES: To describe problems identified as most important by patients with chronic low-back pain and to evaluate the Canadian Occupational Performance Measure (COPM) as a tool for measuring problem-specific outcomes. SUMMARY OF BACKGROUND DATA: Patients with chronic low-back pain report difficulties with a variety of activities. The COPM permits the identification and measurement of problems of particular concern to the patient. MATERIALS AND METHODS: COPM, likert-modified Roland and Morris Disability Questionnaire, Pain Self-Efficacy Questionnaire, and 5-minute walk test were administered at baseline, immediately after, and 9 months after intervention. Differences and statistical interactions were determined by nonparametric tests. RESULTS: Participants identified 60 different types of problem activity, 45 of which were identified by nine or fewer participants. Decreased walking tolerance was the most frequently identified problem (56% of participants). Improvements were observed in all outcomes following intervention. Approximately one third of participants reported improvements two or more COPM units in overall performance and satisfaction with their performance at 9 months. Higher reported performance and satisfaction were associated with greater self-efficacy. Increased reported walking performance was associated with increased observed 5-minute walk distance (R = 0.35, P = 0.02). CONCLUSIONS: Patients with chronic low-back pain report problems with diverse activities. The COPM provides a patient-centered outcome measure that displays good external validity and responsiveness to change when addressing the individual's goals.
