Personality and health‐protective behaviour

Over the last decades much research has been devoted to the analysis of psychosocial factors associated with the development of health problems. However, less attention has been paid to mechanisms explaining why people keep engaging in risky behaviours and do not develop, instead, those habits that could increase their quality of life. To answer these questions, two lines of research have been followed: the main hypothesis of the first line is that there are personality characteristics that predispose the development of certain patterns of behaviour. The second line is focused on the analysis of the psychological processes that, together with situational factors, explain what behaviour is initiated and how it is maintained or changed. The main purpose of this paper is to review these two lines of research: what their main contributions are and what the problems they face are. Copyright © 1999 John Wiley & Sons, Ltd.
