This work is based upon a research study whose purpose was to collect new information about the special benefits and drawbacks of formal organizations' efforts at social network building for older women. In it, a two-tiered investigation was carried out: a national review of a select group of model self-help support programmes for older women throughout the United States; and an in-depth community case study of a nationally recognized model program of self-help support groups, leadership training, networking and community outreach/education for older women. It provides the research-oriented reader with scientific evidence to assess the relative efficacy of self-help group programming.
