OBJECTIVES The purpose of this study was to examine the association between the perceptions of spousal support self-efficacy in terms of dietary self-care and relationship happiness. METHODS Forty-six couples, in which only one spouse has type 2 diabetes, completed questionnaires on perceptions of spousal support self-efficacy and relationship happiness. RESULTS Using an actor‒partner interdependence model, we found that, when persons with type 2 diabetes were more confident in their spouse's ability to provide them with support regarding their dietary self-care, they reported more relationship happiness. We also found that, when their spouse without diabetes was more confident in their own abilities to provide such support to their partner, they reported more relationship happiness. However, the person with diabetes' confidence in their spouse's support abilities and the spouse's confidence in their own support abilities were not associated with the other partner's relationship happiness. CONCLUSIONS This study offers a unique dyadic perspective on the determinants of happiness for couples in which one spouse has type 2 diabetes. The perceived quality of spousal support appears to be associated with relationship happiness in committed couples managing diabetes, regardless of the actual support received or provided.

2 型糖尿病患者及其配偶的配偶支持和关系幸福

目的 本研究的目的是检验配偶支持自我效能感在饮食自我保健和关系幸福方面的关系。方法 46 对夫妇，其中只有一个配偶患有 2 型糖尿病，完成了关于配偶支持自我效能感和关系幸福感的问卷调查。结果 使用演员-伴侣相互依赖模型，我们发现，当 2 型糖尿病患者对其配偶在饮食自我保健方面提供支持的能力更有信心时，他们报告的关系幸福感更高。我们还发现，当他们没有糖尿病的配偶对自己为伴侣提供这种支持的能力更有信心时，他们报告的关系幸福度更高。然而，患有糖尿病的人 对配偶支持能力的信心和配偶对自己支持能力的信心与另一方的关系幸福感无关。结论 本研究为配偶一方患有 2 型糖尿病的夫妻幸福的决定因素提供了独特的二元视角。无论收到或提供的实际支持如何，配偶支持的感知质量似乎与治疗糖尿病的忠诚夫妻的关系幸福感有关。
