Objective To investigate the status of dyadic coping in young and middle-aged type 2 diabetes patients,and to explore the influencing factors. Methods A total of 411 young and middle-aged type 2 diabetes patients were recruited from 2 tertiary hospitals in Zhengzhou from February to December 2020,and they were investigated with a general information questionnaire,Dyadic Coping Inventory（DCI） and Diabetes Self-efficacy Scale（DSES）. Results The total DCI score was 130.60±11.26 and the total DSES score was 93.11±18.93,showing significantly positive correlation（r=0.323,P<0.05）. Gender,duration of disease,family monthly income and self-efficacy were main factors affecting dyadic coping of patients（P<0.05 for all）. Conclusion The level of dyadic coping in type 2 diabetes patients are average and needs to be further improved. Self-efficacy can be used as the starting point to develop feasible and effective interventions to enhance dyadic coping of patients with type 2 diabetes in clinical nursing.

Concept mapping provides a framework for addressing related research problems related to stakeholders. This review introduces the concept and implementation steps of concept mapping and its application status in evidence transformation and application projects,including identifying research problems and research needs,exploring barriers and facilitators,selecting and tailoring implementation strategies,and developing conceptual frameworks and measurement tools. This review also summarizes the application prospect of concept mapping to promote the application of concept mapping in the domestic evidence transformation and application research.
