Psychometric properties of the diabetes skills checklist for adolescents with type 1 diabetes and their parents

Objective Among adolescents with type 1 diabetes, research has found that their perception of their diabetes management is an important predictor of actual diabetes management. There is a need for measures that assess adolescents' perception of their ability to independently complete daily diabetes self-care tasks. The current study examined the psychometric properties of the Diabetes Skills Checklist Teen-Report (DSC-T) and DSC Parent of Teen-Report (DSC-PT), which assess perceived independence in diabetes self-care skills. Research Design and Methods Data were from 1450 adolescents aged 12 to 18 years and their parents who participated in the Diabetes Camp Matters Study. Families completed the DSC as well as other questionnaires online assessing demographic and diabetes-related information, diabetes strengths, and diabetes-specific emotional distress. Results Exploratory factor analysis revealed a 14-item DSC-T and 12-item DSC-PT, both with excellent internal consistency and concurrent validity. Both the DSC-T and DSC-PT were found to be positively correlated with diabetes strengths and negatively correlated with HbA1c, and the DSC-PT was significantly correlated with parent-reported diabetes distress. Adolescents who used insulin pumps and continuous glucose monitoring reported higher perceived independence in diabetes self-care skills compared to adolescents who used insulin pens/syringes or blood glucose meters. No differences were found based on demographic characteristics. Conclusions The DSC-T and DSC-PT have strong potential to be used during diabetes clinic visits to spark discussion regarding adolescents' self-care, which would allow for a more successful transfer of diabetes care from parent to adolescent, and eventually, the transition from pediatric to adult healthcare.

Automated summary

Research indicates that adolescents' perception of their diabetes management is a significant predictor of actual management. The Diabetes Skills Checklist Teen-Report (DSC-T) and DSC Parent of Teen-Report (DSC-PT) were found to have excellent psychometric properties, with positive correlations with diabetes strengths and negative correlations with HbA1c. The tools show potential for promoting successful transition of diabetes care from parent to adolescent during clinic visits.
