糖尿病痛苦在老年T2DM患者抑郁症状与自我效能间的中介效应研究

  目的  探讨抑郁症状对社区老年2型糖尿病患者(type 2 diabetes mellitus, T2DM)自我效能的影响，以及糖尿病痛苦在其中的中介作用。  方法  采用便利抽样的方式对某社区服务管理中心的248名老年T2DM患者进行问卷调查。同时收集一般人口学特征、糖尿病相关信息、自我效能、抑郁症状和糖尿病痛苦情况。多元线性回归分析模型分析抑郁症状对自我效能的影响，Bootstrap法进行中介分析。  结果  抑郁症状(β=-0.272, P < 0.01)和糖尿病痛苦(β=-0.345, P < 0.01)是自我效能的影响因素，糖尿病痛苦在抑郁症状与自我效能之间具有中介作用(Boot CI: -2.460 2~-0.783 9, P < 0.05)。  结论  情绪障碍的改善有利于社区老年T2DM患者自我效能水平的提高。

The mediating effect of diabetic distress on depressive symptoms and self-efficacy in elderly pa-tients with T2DM

  Objective  To explore the influence of depression on self-efficacy in elderly patients with type 2 diabetes mellitus (T2DM) in the community and the mediating role of diabetic distress.  Methods  By convenience sampling, the 248 elderly T2DM patients managed by a community service center were investigated with questionnaire. The general demographic characteristics, diabetes-related information, self-efficacy, depression, and diabetic distress were collected. Multiple linear regression model was used to analyze the influence of depression on self-efficacy, and Bootstrap method was used for mediation analysis.  Result  Depression (β=-0.272, P < 0.01) and diabetes distress (β=-0.345, P < 0.01) were associated risk factors of self-efficacy, and diabetes distress played a mediating role between depression and self-efficacy (Boot CI: -2.460 2~-0.783 9, P < 0.05).  Conclusion  An important way to enhance the level of self-efficacy of elderly patients with T2DM in the community may be improving emotional disorder.
