Self-care confidence mediates the relationship between type D personality and self-care adherence in chinese heart failure patients

Background: Existing theory and evidence suggest that self-care confidence may mediate the relationship between Type D personality and self-care adherence. Objectives: To assess the mediating role of self-care confidence between Type D personality and self care adherence in Chinese HF patients. Methods: This is a secondary analysis of a cross-sectional study. Self-care confidence and self-care adherence (maintenance) were measured by the subscales of the Self-Care of Heart Failure Index (v6). The Type D Scale-14 was administered to assess negative affect (NA), social inhibition (SI), and Type D personality. Mediation analysis based on Baron and Kenny was performed. Results: A total of 127 HF patients were included. Self-care confidence partially mediated the relationship between Type D personality and self-care adherence but completely mediated the relationship between NA/SI and self-care adherence. Conclusions: Clinicians may effectively improve self-care adherence by enhancing self-care confidence in HF patients with Type D personality. (C) 2018 Elsevier Inc. All rights reserved.
