Objective: To assess the relationship among Type D personality, self-efficacy, and medication adherence in patients with coronary
heart disease.
Methods: The study design was prospective and observational. Type D personality, self-efficacy for illness management
behaviors, and medication adherence were measured 3 weeks after hospitalization for acute coronary syndrome in 165 patients (mean
[standard deviation] age = 61.62 [10.61] years, 16% women). Self-reported medication adherence was measured 6 months later in 118
of these patients. Multiple linear regression and mediation analyses were used to address the study research questions.
Results: Using
the original categorical classification, 30% of patients with acute coronary syndrome were classified as having Type D personality.
Categorically defined patients with Type D personality had significantly poorer medication adherence at 6 months (r = j0.29, p G .01).
Negative affectivity (NA; r = j0.25, p = .01) and social inhibition (r = j0.19, p = .04), the components of Type D personality, were
associated with medication adherence 6 months after discharge in bivariate analyses. There was no evidence for the interaction of NA
and social inhibition, that is, Type D personality, in the prediction of medication adherence 6 months after discharge in multivariate
analysis. The observed association between NA and medication adherence 6 months after discharge could be partly explained by
indirect effects through self-efficacy in mediation analysis (coefficient = j0.012; 95% bias-corrected and accelerated confidence
interval = j0.036 to j0.001).
Conclusions: The present data suggest the primacy of NA over the Type D personality construct in
predicting medication adherence. Lower levels of self-efficacy may be a mediator between higher levels of NA and poor adherence to
medication in patients with coronary heart disease.
