title: Do health beliefs predict health behaviour? An analysis of breast self-examination.
abstract: The purpose of this paper is to explore the relationships between health beliefs and health behaviour. The study we report was conducted as part of a national campaign to evaluate the benefits of breast self-examination in the early detection of breast cancer, and the purpose of our analysis was to test the Health Belief Model of Becker and his colleagues. Three groups of women were investigated--278 who accepted an invitation to attend self-examination classes and were taught the techniques in detail, 262 who declined the invitation and 594 controls to whom no classes were offered--and beliefs and self-reported behaviour were measured shortly before the classes took place and again a year later. The campaign, it emerged, produced marked changes in both beliefs and behaviour, but the relationships between beliefs and behaviour were much weaker than the model had led us to expect and accounted for no more than a quarter of the variance. Alternative models are considered, notably Fishbein and Ajzen's Theory of Reasoned Action, and the paper concludes with some suggestions for improving health campaigns.
