Objective. Evaluation of a self-management program for patients with osteoa rthritis (OA) of the hip or knee. The program, which consisted of 6 weekly sessions of 2 hours, included health education by a peer and physical exerc ises taught by a physical therapist. Methods. Randomized controlled trial. Inclusion criteria were diagnosis of OA of the hip or knee according to ACR clinical and radiographic criteria a nd age 55 to 75 years. Exclusion criteria: on waiting list for joint replac ement. There were pretest, posttest, and followup (6 months) assessments. T he experimental group consisted of 56 patients, the control group 49. Outco me variables were pain, quality of life, activity restrictions, knowledge a bout OA, self-efficacy, body mass index (BMI), and mobility measures. Atten tion was also paid to effects on health care utilization and lifestyle beha vior. Results. Significant MANOVA group x time effects (p < 0.05, one-sided) were found for pain, quality of life, strength of the left M. quadriceps, knowl edge, self-efficacy, BMI, physically active lifestyle, and visits to the ph ysical therapist. Most effects were moderate at posttest assessment and sma ller at followup. No effects were found for range of motion and functional tasks. Conclusion, The program was reasonably effective, but more attention should be paid to proactive followup interventions and to the selection of partic ipants.
