Health Locus of Control and Physical Activity in Liver Transplant Recipients.

INTRODUCTION

Health locus of control has the potential to influence health behavior among individuals with chronic diseases. However, little is known regarding the relationship between locus of control and physical activity in transplant recipients. The aim of the study was to investigate health locus of control and physical activity in liver transplant recipients.

METHODS

Seventy-six liver transplant recipients were enrolled. The Multidimensional Health Locus of Control - Form C, including internal, chance, doctors, and powerful others subdimensions, was used to evaluate the health locus of control. Physical activity was assessed with the International Physical Activity Questionnaire - Short Form.

RESULTS

The median internal health locus of control score was 28.54. Thirty-six participants had low, 35 participants had moderate, and five participants had high physical activity. Internal health locus of control was higher in patients having moderate activity compared to patients with low activity (p=0.04). "Doctors" subdimension of health locus of control was negatively correlated with walking (r=-0.38, p=0.02) and total activity scores among patients with low activity (r=-0.37, p=0.02).

CONCLUSION

Liver transplant recipients with moderate activity present higher internal health locus of control scores, suggesting a possible influence of physically active behavior on the beliefs of one's own control over disease management. As the activity level increases, the belief that health outcomes are largely the responsibility of health professionals decreases among liver transplant recipients with low activity. Promoting physical activity will help develop the control of one's own actions on health after liver transplantation.
