Relationship between Diabetes Family Conflicts or Problem Recognition in Illness Self-Management and Quality of Life of Adolescents with T1DM and Their Parents

This study aimed to investigate the relationship between diabetes family conflicts or problem recognition in illness self-management (PRISM) and the parental perceived quality of life (QoL) of adolescents with type 1 diabetes mellitus (T1DM) and their parents. This was a cross-sectional study, and the participants comprised 111 parents of type 1 diabetes adolescents; data were collected via an online survey and analyzed by descriptive statistics, correlation, and multiple linear regression analysis using the IBM SPSS 25.0 program. The explanatory power of the QoL model in parents of adolescents with T1DM, constructed using three variables—diabetes family conflict (B = −0.56), regimen pain and bother (B = −11.25), and peer interactions (B = −7.48), which are PRISM barriers—was 35.7% (F = 5.70, p < 0.001). Diabetes family conflicts (B = −0.86) and peer interactions (B = −9.04) explained 57.3% of the variance in the parental perceived QoL of adolescents with T1DM (F = 12.33, p < 0.001). In order to improve the QoL in parents and adolescents with type 1 diabetes, interventions to effectively manage diabetes family conflicts and improve peer interactions are necessary.
