Abstract: Previous conclusions regarding the role of social support in hemodialysis adherence are inconsistent, suggesting that other factors may moderate this relationship. Using the Five-Factor Model of Personality, we examined the hypothesis that conscientiousness would interact with social support in predicting fluid-intake and medication adherence in a sample of 56 chronic hemodialysis patients. Hierarchical regression analyses (controlling for demographic, clinical, and other personality variables) revealed a significant interaction between social support and conscientiousness. However inconsistent with prediction, high support among patients with low conscientiousness was associated with poorer fluid-intake adherence, while support had little effect on fluid-intake adherence among high conscientiousness patients. No main or interactive effects were found for support or conscientiousness on a measure of medication adherence.
