The effects of the locus of control on physical health as well as the basic mechanisms through which it exerts its effects are reviewed in the present article. Theoretical bases of the locus of control, its measurement and its relationships to similar psychological constructs, especially various aspects of perceived control, are described in the first part of the article. Further, the most important empirical results on the effects of the locus of control on physical health are shown. Four primary mechanisms through which the locus of control may affect physical health are proposed – through its effects on cardiovascular and immunological functioning as well as health behaviors and coping with stress. Finally, the most relevant theoretical and methodological problems characteristic of the research on the relationship between the locus of control and physical health are reported.
