An RCT of a family intervention for adolescents living with type 1 diabetes: Who benefits most?
Authors' conclusion
While family dynamics improved for all, adolescents' quality of life improved among youth with fewer resources and from marginalized racial and ethnic backgrounds, whereas parents with higher distress benefited most. For adolescents, socioeconomic context may drive intervention response.

Primary result
As reported in the abstract
Improved health-related quality of life (HRQOL) with the intervention at 3-month post-baseline among racial and ethnic minoritized adolescents
β = 0.308, p = 0.002, d = 0.81
Improved HRQOL with the intervention at 3-month post-baseline among adolescents not using AID systems
β = 0.261, p = 0.003, d = 0.94
Improved HRQOL with the intervention at 6-month post-baseline among adolescents not using AID systems
β = 0.220, p = 0.005, d = 0.58
Secondary outcomes
| Outcome | β | P value |
|---|---|---|
| Parenting, full sample · immediately after the interventionIntervention vs Waitlist control · parent report of supportive parenting; d = 0.31 | 0.151 | P = 0.007 |
| Parenting, full sample · immediately after the interventionIntervention vs Waitlist control · parent report of unsupportive parenting; d = −0.36 | −0.177 | P = 0.002 |
| Parenting, full sample · immediately after the interventionIntervention vs Waitlist control · adolescent report of unsupportive parenting; d = −0.30 | −0.150 | P = 0.024 |
| Parent diabetes distress, parents with high baseline distressReduced distress; d = −0.54 | −0.200 | P = 0.006 |
