Randomized Controlled Trial
Using Illness Perceptions to Cluster Chronic Pain Patients: Results From a Trial on the Chronic Pain Self-Management Program.
The aims of our study were (1) to identify possible subgroups of individuals with chronic pain based on their illness perceptions (IPs); (2) to examine whether these subgroups differed in health status and health expenditure; and (3) to examine whether the subgroups differed in their response to participation in a lay-led Chronic Pain Self-Management Program (CPSMP). ⋯ Clusters based on IPs meaningfully distinguished individuals with chronic pain on health measures and outcome of participating in the CPSMP, and may prove useful in future studies to understand responses to treatment.
