The chain mediating role of dyadic coping and benefit finding in the relationship be-tween diabetes distress and sleep quality in type 2 diabetes patients
Objective To construct chain mediation models to examine whether dyadic coping and benefit finding mediate the effects of diabetes distress on sleep quality in patients with type 2 diabetes.Methods A convenience sample of 221 patients with type 2 dia-betes were surveyed by using a demographic questionnaire,the Diabetes Distress Scale,the Dyadic Coping Inventory,the Benefit Finding Scale and the Pittsburgh Sleep Quality Index.Results The scores of diabetes distress,dyadic coping,benefit finding and sleep quality were 29.75±13.94,116.20±21.67,34.94±11.98,4.00(2.00,8.00),respectively.The effects of diabetes distress had a direct link on sleep quality,with the direct effect accounting for 52.0%of the total effect,and had three indirect paths on sleep quality:the independent mediating role of dyadic coping was 18.4%,the independent mediating role of benefit finding was 16.0%,as well as the completely chain mediating role of dyadic coping and benefit finding was 13.6%.Conclusion Dyadic coping and benefit finding are part of a causal chain between the effects of diabetes distress and sleep quality among patients with type 2 diabetes.By enhancing dyadic coping and benefit finding in patients with type 2 diabetes,the effect of diabetes distress on sleep quality can be attenuated.
