"For many years, social cognition models have been at the forefront of research into predicting and explaining health behaviours. Until recently, there have been few attempts to go beyond prediction and understanding to "intervention"--But now the position has changed, and a number of excellent interventions have been set up. The purpose of this book is to bring them together in one volume." "There are nine chapters each addressing a particular behaviour or set of behaviours. The chapters follow a common structure: a presentation of the "epidemiological facts" about the behaviour and why an intervention was needed; an outline of the way in which the theoretical model being used was adapted for the intervention; a presentation of the experimental results; and a discussion of their theoretical and practical implications. The book ends with a chapter of commentary on the challenges of devising theory-based interventions."
