Originally published in 1986, the central topic of this book is the analysis and application of control-related beliefs and behaviours for theory and practice in the psychology of aging. The volume was written for two specific interrelated purposes aimed at cross-fertilization between the psychology of control and the field of gerontology. The first purpose was to summarise available research and theory on the psychology of control for researchers and professionals interested in gerontology at the time. The second was to enrich the field of the psychology of control.
