Abstract
The shift in diabetes management responsibility is critical for adolescents with type 1 diabetes (T1D). Currently, in Japan, there is insufficient progress in the development of scales for evaluating diabetes management responsibility. We developed the Japanese version of the Diabetes Family Responsibility Questionnaire (DFRQ), a scale to evaluate diabetes management responsibility, and verified its reliability and validity. We recruited 12-18-year-old adolescents with T1D and their caregivers. The DFRQ questionnaires (DFRQ-A for adolescents and DFRQ-C for caregivers) were distributed. The responses of 31 pairs were analyzed (adolescents: 9 males, 22 females; mean age: 14.8 ± 1.5 years). The median total DFRQ scores of adolescents (30.0) and caregivers (32.0) were not significantly different (p = 0.269). The internal consistencies (Cronbach's α) were 0.784 and 0.687 for DFRQ-A and DFRQ-C, respectively. DFRQ-A scores and adolescent age demonstrated a weak statistically significant negative correlation (r = - 0.397, p = 0.027), whereas DFRQ-C scores and adolescent age demonstrated a weak negative correlation not statistically significant (r = - 0.311, p = 0.089). Both scores were significantly negatively correlated with self-efficacy for diabetes self-management scores (r = - 0.390, p = 0.030; r = - 0.478, p = 0.006, respectively). Furthermore, a significantly moderate positive correlation was found between these scores (r = 0.624, p < 0.001). We confirmed the reliability and validity of the Japanese version of DFRQ. DFRQ is expected to be used as a dyadic scale to evaluate the status of diabetes management responsibility and its transition during adolescence in Japan.
