BackgroundExisting theory and evidence suggest that self-care confidence may mediate the relationship between Type D personality and self-care adherence.ObjectivesTo assess the mediating role of self-care confidence between Type D personality and self-care adherence in Chinese HF patients.MethodsThis 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.ResultsA 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.ConclusionsClinicians may effectively improve self-care adherence by enhancing self-care confidence in HF patients with Type D personality. |
