Following Physician's Advice in Late Life: The Roles of Health Beliefs and Health Status.

Objective: This study aims to explore the influence of health-related locus of control beliefs such as belief in the role of health professionals in influencing patient health, cognitive functioning, and multimorbidity on adherence to physician's recommendations among older adults.

Methods: A cross-sectional study involving older adults (N=684, age range = 71-100 years) living in Clearwater, Florida, reported their adherence to physician's recommendations, cognitive functioning, physical health, and health-related locus of control beliefs. Ordered Logistic regression was used.

Results: Older adults who believed that health professionals influence health and a person is likely to recover from illness because other people take good care of him/her had higher adherence to physician's recommendations. Older adults who believed that their own action affects their health had lower odds of reporting adherence by 27%. Additionally, those with cognitive impairment had lower odds of reporting adherence by 38%. Functional limitations, multimorbidity, and self-image of health were not associated with adherence.

Conclusion: This is one of the first studies to consider the influence of locus of control beliefs on adherence of physician's recommendations among community dwelling older adults. With the exception of one item "My good health is largely a matter of good fortune", generally individuals with external locus of control had higher adherence. Our findings also underscore the policy and clinical significance of different health-related beliefs held by older adults.
