Health Locus of Control and Health Behaviors in Organ Transplant Recipients: A Multicenter Study

Abstract

Background: Adherence to health behaviors and to immunosuppressant medications are variables among heart transplant recipients with potential life-threatening outcomes. It is understood that patients with psychosocial barriers are at increased risk of poor outcomes due to various factors. Health locus of control includes any activity that can be done to prevent health problems. Health locus of control is defined as individual beliefs based on past experiences in health issues and having internal and or external control. The literature suggests that patients with a strong internal locus of control have a sense of responsibility for their health behaviors.

Purpose: To investigate the effect of the health locus of control on the level of self-reported health behaviors among organ transplant recipients.

Materials and methods: A cross-sectional design was used for this study. The study group comprises 222 individuals after heart, kidney, lung, and liver transplantation. The following standardized tools were used: The Multidimensional Health Locus of Control, The Health Behavior Inventory, Morisky Medication-Taking Adherence Scale 4-item. Data were analyzed using IBM SPSS. The level of significance for the statistical test was set at 0.05.

Results: Powerful Others scored the highest among the 3 Health Locus of Control scales in heart, kidney, and liver recipients. Participants paid little attention to Healthy eating habits; however, the total score of the Health Behavior Inventory was high (91.68-94.40). There was a difference between the kind of transplant and center for 4 aspects of health behavior. Higher scores of The Multidimensional Health Locus of Control were associated with higher scores of Health Behaviors and level of adherence. Greater Powerful Others and Internal Health Locus of control predict higher health behaviors explaining 42 % of the variance.

Conclusions: The intensification of declared health behaviors is high. However, in educating posttransplant patients, attention should be paid to strengthening proper healthy eating habits. Associations between health locus of control dimensions and health behavior have been shown among transplant recipients. The health locus of control significantly predicts the intensity of health behaviors. these findings support the need to consider health control beliefs while designing preventive strategies in this group of patients.
