Abstract
BACKGROUND: Several studies have shown that non-adherence is a common and increasing problem among individuals with chronic illnesses, including hemodialysis patients. PURPOSE: The present study aimed to investigate the influence of depression and health cognitions on medication adherence among patients undergoing hemodialysis. METHOD: A sample of 168 participants was recruited from six general hospitals in the broader area of Athens, consisting of patients undergoing in-center hemodialysis. Measurements were conducted with the following instruments: the Medication Adherence Rating Scale, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Multidimensional Health Locus of Control (MHLC) scale. RESULTS: The results indicated that medication adherence was associated positively with the dimensions of internal and doctor-attributed health locus of control, measured by the MHLC. It was also related negatively to depression, measured by the CES-D. CONCLUSIONS: The present study demonstrates the importance of depression in understanding the medication adherence of hemodialysis patients, as well as the contribution of heath cognitions.
