Abstract

Background: Type D personality is associated with medication non-adherence. Both Type D personality and non-adherence are predictors of poor outcomes. Self-efficacy, which is modifiable, is also associated with medication adherence. Objectives: To determine the relationships among Type D personality, self-efficacy, and medication adherence in 84 heart failure patients. Methods: Self-efficacy, Type D personality, medication adherence, demographic and clinical data were collected. Hierarchical linear regression was used. Results: Type D patients were more likely to have lower self-efficacy (p =023) and medication non-adherence (p =027) than non-Type D patients. Low self-efficacy was associated with medication non-adherence (p <.001). Type D personality didn't predict medication adherence after entering self-efficacy in the model (p =422), demonstrating mediation. Conclusions: Self-efficacy mediates the relationship between Type D personality and medication adherence. Developing and applying interventions to enhance self-efficacy may help to sever the link between Type D personality and poor outcomes.
