Abstract
Fluid noncompliance in patients with end-stage renal disease (ESRD) is a widespread problem with severe consequences for health. In addition, ESRD patients report considerable stress in relation to their illness and dialysis treatment. The present study examined the role of cognitive and emotional variables in fluid noncompliance, symptomatology, and stress. Fifty hemodialysis patients were assessed (a) on the cognitive variables of locus of control, self-evaluations of their past compliance, and self-efficacy to resist fluid intake and (b) on the emotional variables of depression, anger, and anxiety. Results showed that cognitive variables accounted for fluid noncompliance and predicted future adherence. Patients high in negative emotions complied equally as well as patients low in negative emotions but were found to report substantially more symptomatology and distress associated with their treatment. The implications of these findings for treatment of ESRD patients and future research are discussed.
