This study examined the underlying variables of selected reminiscing processes to determine those that contributed to well-being. Two hundred and forty subjects randomly selected from nursing homes and high-rises participated in one of 10 different reminiscing modalities for eight weeks. Measures of life satisfaction (LSI-A), psychological well being (ABS), selfesteem (SES), and depression (BDI) were given pre- and postintervention to determine the most therapeutic treatment modalities. Results showed the most therapeutic way to reminisce was through a structured, evaluative life review performed on an individual basis. Thus, three variables contributed to successful reminiscing: individuality (one-to-one reminiscing), evaluation (a personal valuing of events), and structure (covering the whole life span).
