Investigation of Anxiety and Health Locus of Control in Patients Undergoing Hemodialysis.

Abstract

Hemodialysis is the most frequent treatment modality for End-Stage Renal Disease (ESRD). However, a number of limitations and modifications accompany this treatment, affecting people's physical and psychological well-being and increasing anxiety symptoms. The aim of this study was to investigate the level of anxiety and health locus of control among dialysis patients. One hundred and five patients on hemodialysis treatment completed a questionnaire with demographic characteristics, the State-Trait Anxiety Inventory and the Multidisciplinary Health Locus of Control Scale. Women had significantly higher levels of state anxiety than men (p=0.019). Similarly, patients with primary school education had significantly higher trait and total anxiety levels than those with technological education (p=0.002 and p=0.033, respectively). Widowed patients exhibited significantly higher state, trait, and total anxiety levels than married (p=0.032, p=0.012, and p=0.012, respectively). Participants who did not do any kind of exercise had significantly higher level of state, trait, and total anxiety than those who did (p=0.011, p=0.015, and p=0.006, respectively). Respondents who did not have any self-care skills had significantly higher level of state, trait, and total anxiety than those who had (p=0.011, p=0.015, and p=0.006, respectively). State, trait, and total anxiety levels were significantly (p≤0.05) correlated negatively with internal locus of control and positively with "chance" locus of control scale. Hemodialysis patients had increased anxiety symptoms and believed that others had control over their health to a greater extent. Renal professionals need to apply effective interventions to dialysis patients in order to help them gain a better sense of control over their health and reduce anxiety symptoms.
