Psychoeducational intervention: A critical review of systematic analyses

There was evidence that the effectiveness of patient education and progressive muscle relaxation (PMR) has been found to be positive and there was support for their clinical use. The overall effectiveness of PEI was inconclusive because a mixture of interventions was studied and both significant and non-significant results had been reported. Future large-scale studies focusing on some commonly used interventions such as PMR, education, and counseling are recommended. Special consideration is given to the selection of understudied subjects, the selection of well-defined intervention and control, the selection of outcome measures and the research design.
