Abstract
This study examined what is measured by adolescents’, mothers’, and fathers’ reports of adolescents’ adherence to the type 1 diabetes regimen and how such reports relate to HbA1c and daily blood glucose. Two-hundred fifty-two adolescents (M age = 12.49 at baseline), mothers, and 188 fathers completed an adapted Self-Care Inventory (LaGreca et al. in Child Health Care 19(3):132–139, 1990) every 6 months for 2.5 years, HbA1c was gathered from medical records, and daily number of blood glucose tests (BGT) and blood glucose mean (BGM) were obtained from glucose meters at one time point. A multitrait-multimethod approach decomposing adherence indicated that fathers’ reports reflected a stable perception across time, mothers’ reports a shared view within the family that varied with HbA1c across time, and adolescents’ reports a unique view. Fathers’ and mothers’ reports were related to HbA1c; adolescents’ reports were not, but were uniquely associated with BGT. Family members’ adherence reports capture different information across time, with implications for measuring adherence and for family processes.
