Aims. To examine the association between Type D personality and HbA1c level and to explore the mediating role of medication adherence between them in patients with type 2 diabetes mellitus (T2DM). Methods. 330 patients went on to complete a self-report measure of medication adherence and the HbA1c tests. Chi-square test, test, Ordinary Least Square Regression (OLS), and Recentered Influence Function Regression (RIF) were employed. Results. Patients with Type D personality had significantly higher HbA1c value (). When Type D personality was operationalized as a categorical variable, SI was associated with HbA1c (). When NA, SI, and their interaction term were entered into regression, all of them were no longer associated with HbA1c level (). On the other hand, when Type D personality was operationalized as a continuous variable, only SI trait was associated with HbA1c level (). When NA, SI, and term together were entered into regression, only SI was not related to HbA1c level. Furthermore, medication adherence had a significant mediation effect between Type D personality and HbA1c, accounting for 54.43% of the total effect. Conclusion. Type D personality was associated with HbA1c in direct and indirect ways, and medication adherence acted as a mediator role.
