Daily Diabetes-Specific Family Conflict, Problems, and Blood Glucose During Adolescence

Diabetes-related family conflict is widely regarded as a risk factor for diabetes outcomes, yet it has not been examined on a daily basis. Parental acceptance may attenuate the degree to which family conflict is associated with diabetes outcomes. The present study examined (a) within- and between-person fluctuations in diabetes problems and family conflict, (b) within- and between-person links between conflict and blood glucose (BG) mean, and (c) whether parental acceptance moderated these associations. One hundred eighty adolescents (M-age = 12.92 years) with T1D completed a 14-day diary measuring diabetes problems, conflict with mother, conflict with father, and parental acceptance at the end of each day. Daily average BG values were calculated from glucometer readings. Higher diabetes problems on average across the 14-day diary were associated with more average conflict with mothers (between-person), but daily fluctuations in the number of diabetes problems were not related to daily conflict (within-person). Adolescents with higher conflict with mothers and fathers on average across the 14 days had higher BG means (between-person); however, on days when adolescents reported higher conflict, they had greater risk for low BG (within-person). Daily parental acceptance did not moderate associations between problems and conflict nor conflict and BG mean. This study was the first to examine daily diabetes-specific conflict with mothers and fathers during adolescence. The number of diabetes problems did not predict daily conflict. Fluctuations in daily conflict were associated with greater risk for low BG, underscoring the need for future research examining in-the-moment relations among conflict and BG extremes.
