Prostate cancer support groups: a literature review.

This article provides an overview of research literature related to cancer support groups, with particular reference to prostate cancer groups. Randomized studies of cancer support groups primarily focus on short-term psychoeducational and/or supportive/expressive groups for women with breast cancer. Many of these studies suggest that the interventions lead to a pronounced improvement in psychological functioning and may in some instances increase longevity. Regarding prostate cancer support group members, information and education are especially valued. Open-ended, psychoeducational groups with large meetings, expert speakers, and structured, efficient organizations appear most beneficial to prostate cancer group members. The literature only partially answers a number of significant questions, including the types of group most appropriate for people with specific diseases, process variables most significant to the success of groups, and specific factors that are barriers to group involvement by certain populations.
