Abstract

OBJECTIVE - The authors developed and validated a semi-structured interview, the Diabetes Self-Management Profile (DSMP), to measure self-management of type 1 diabetes. The DSMP includes the following regimen components: exercise, management of hypoglycemia, diet, blood glucose testing, and insulin administration and dose adjustment. RESEARCH DESIGN AND METHODS - Families of youths with type 1 diabetes (n = 105) who were entering a controlled trial of intensive therapy (IT) versus usual care (UC) were administered the DSMP. Analyses assessed the reliability and validity of the DSMP, including its associations with HbA1(c) and quality of life. RESULTS - The DSMP total score has adequate internal consistency (Cronbach's α 0.76), 3-month test-retest reliability (Pearson correlation, r = 0.67), inter-interviewer agreement (r = 0.94), and parent-adolescent agreement (r = 0.61). DSMP total scores (r = -0.28) and 3 subscales correlated significantly with HbA1(c) (diet [r = -0.27], blood glucose testing [r = -0.37], and insulin administration and dose adjustment [r = -0.25]). Adolescents' reports of self-management did not differ from parental reports. Higher DSMP scores were associated with more favorable quality of life for mothers and youths. CONCLUSIONS - The DSMP is a convenient measure that yields a reliable and valid assessment of diabetes self-management. Compared with extant similar measures, the DSMP is more strongly correlated with HbA1(c).
