The design and evaluation of psychoeducational/self-management interventions.

A large number of interventions have been developed with the aim of improving patient self-management of arthritis. These interventions are complex, usually including multiple components, and have certain key features including participants' awareness of the arms of the study and their often having clear preferences for one or other arm. Because of these and other differences the randomized controlled trial is not necessarily ideal for studies of self-management interventions. This special interest group (SIG) considered designs that may be more appropriate. Self-management interventions use a wide range of outcome measures, which are often assessed at a range of time periods after the intervention. Evaluation of the efficacy of self-management interventions was discussed. One important issue is to link the expected influence of the intervention to the key assessment of outcome. The SIG also examined the factors that may influence the effectiveness of self-management interventions.
