NCT04589689

Brief Summary

The "Insul-In This Together" intervention is designed for teens with Type 1 Diabetes and their parents. This study seeks to evaluate an evidence-based family intervention for teens with type 1 diabetes and their parents to offset the psychosocial and diabetes self-management risks. This information will provide a more in-depth understanding of family-based program efficacy for teens with adolescents and provide more judicious and streamlined intervention options to be offered in diabetes clinics in the future.

Outcome Measures

Primary Outcomes (2)

  • Glucose Levels Percent Time in Target Range Based on Glucose Monitoring

    Adolescent glucose levels percent time in target range (70-180 mg/dL) based on glucose monitoring to measure glycemic control. The clinical recommendation is a percent time-in-range of 70% or more.

    Average percent time in range based on two weeks of glucose monitoring data at baseline, 3-month, and 6-month follow-up (plus or minus 2 weeks around target data collection date)

  • Adolescent Quality of Life

    Self-report via Type 1 Diabetes and Life (T1DAL) surveys for adolescents to measure the adolescent's quality of life. Possible score range is 0-100 and the higher scores indicated better quality of life. Adolescent quality of life was measured for adolescents only (not parents).

    Baseline, 3-month follow-up, and 6-month follow-up.

Secondary Outcomes (6)

  • Adolescent Depression

    Baseline, 3-month follow-up, and 6-month follow-up.

  • Parent Depression

    Baseline, 3-month follow-up, and 6-month follow-up.

  • Adolescent Diabetes Distress

    Baseline, 3-month follow-up, and 6-month follow-up

  • Parent Diabetes Distress

    Baseline, 3-month follow-up, and 6-month follow-up.

  • Parenting Stress

    Baseline, 3-month follow-up, and 6-month follow-up

  • +1 more secondary outcomes

Study Arms (2)

Intervention Group

EXPERIMENTAL

The intervention group will participated in the The Insul-In This Together intervention, which consists of 6 weekly 30-minute online family sessions to discuss topics related to diabetes distress and parent-teen communication. Sessions include structured education, discussions, and skill-building activities related to parental involvement, parental monitoring, and parent-adolescent conflict. The intervention will be conducted by the PI or clinically trained research staff via Zoom. Online surveys, and glucose monitoring data will be captured at baseline and 3,6 and 12-month follow-ups. Brief surveys will also be conducted at 2-, 4-, and 6-week follow-ups (after every 2 sessions for the intervention group and later the control group). Participants will be asked to provide A1C test results that will be collected via chart review or from participants sharing their test results at baseline, 6-month, and 12-month follow-up.

Behavioral: Insul-In This Together

Waitlisted Control Group

EXPERIMENTAL

The waitlisted control group will receive the same intervention as the intervention group, but at the 6-month follow-up mark. The intervention will be conducted by the PI or clinically trained research staff via Zoom. Online surveys, and glucose monitoring data will be captured at baseline and 3,6 and 12-month follow-ups. Brief surveys will also be conducted at 2-, 4-, and 6-week from baseline. Participants will be asked to provide A1C test results that will be collected via chart review or from participants sharing their test results at baseline, 6-month, and 12-month follow-up.
