Research workshop on methodological issues in evaluating preventive interventions using mutual support

The Prevention Research Branch, Division of Clinical Research, of the National Institute of Mental Health held a research workshop on the methodological issues in evaluating preventive interventions using mutual support. This workshop, held in June 1989, was part of an effort to stimulate high-quality research on preventive interventions using mutual support. These interventions include but are not limited to naturally occurring self-help groups. Participants reviewed methodological problems, generated strategies for dealing with these problems, and made recommendations for future research in this area.
