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.

摘要

背景

D型人格与药物治疗依从性差有关。D型人格和依从性差都是不良预后的预测因素。可改变的自我效能感也与药物治疗依从性有关。

目的

确定84例心力衰竭患者中D型人格、自我效能感和药物治疗依从性之间的关系。

方法

收集自我效能感、D型人格、药物治疗依从性、人口统计学和临床数据。采用分层线性回归分析。

结果

与非D型患者相比,D型患者更有可能具有较低的自我效能感(p = 0.023)和药物治疗不依从性(p = 0.027)。自我效能感低与药物治疗不依从性有关(p < 0.001)。在模型中纳入自我效能感后,D型人格并不能预测药物治疗依从性(p = 0.422),表明存在中介作用。

结论

自我效能感介导了D型人格与药物治疗依从性之间的关系。制定和应用增强自我效能感的干预措施可能有助于切断D型人格与不良预后之间的联系。
