Introduction and Objective: We examined whether a new digital intervention targeting diabetes distress in families of school-aged children living with T1D produced domain-specific effects, offering insight into mechanisms of change. Methods: We randomized families (N=34; mean±SD child age=10±1.4 yr; 53% male; HbA1c=7.24±0.7%) to self-guided (app only SG, n=13), enhanced self-guided (app+ 3 video visits ESG, n=11), or app+ 8 video visits (VV, n=10). We compared parent and child Problem Areas in Diabetes-Child (PAID-C) domain scores pre-post treatment and by delivery arm. Results: Overall, parent and child PAID-C scores decreased (p=0.03), with no group differences. Parent reductions concentrated in domains: Keeping up with Demand, Personal Regimen Distress, and Child Regimen Distress (Cohen’s d=047-0.50); child reductions reflected changes in Emotional Burden (d=0.55). Exploratory analyses suggested greater app use predicted larger reductions in child Emotional Burden (=−1.4 points/hour, p=0.09). Conclusion: These findings extend beyond total scores by identifying which types of distress improved and suggest that app engagement could enhance child outcomes, pointing to practical ways to strengthen and expand the intervention.
