Type 1 diabetes (T1D) management is particularly challenging during adolescence as responsibility for management begins to shift from parents to youth, and positive family teamwork is critical to achieving optimal diabetes outcomes. Existing behavioral family interventions for T1D are beneficial but have limited potential for translation to clinical practice, and universal preventive approaches designed to explicitly promote existing T1D management strengths are needed. Ultimately, the goal of this line of research is to validate brief, convenient, and helpful tools that families of all adolescents with T1D can use to strengthen positive family teamwork and ultimately promote optimal diabetes health outcomes.
Type 1 diabetes (T1D) is among the most common chronic conditions of childhood and its management is complex and relentless. Adolescents have increased risk for worsening glycemic control, putting them at risk for short- and long-term complications. As responsibility for daily T1D management tasks begins to shift from parents to youth, supportive parent-adolescent teamwork promotes optimal diabetes outcomes. However, adolescents' cognitive development, desire for autonomy, and changing family and social relationships can make adherence to treatment recommendations difficult and strain attempts at parent-adolescent teamwork. This study aims to develop and pilot test a mobile app-based behavioral intervention to facilitate positive, supportive parent-adolescent interactions around T1D management. The proposed study has two parts. First, adolescents with T1D (age 12-17), their parents, and diabetes care providers will be invited to participate in designing a smartphone app that supports parents to recognize, keep track of, and reinforce their adolescents for specific positive T1D-related behaviors, or strengths. Example strengths include asking for help with complicated diabetes tasks, talking to friends about diabetes, and expressing confidence or optimism about T1D management. Intermittently throughout the day, the app will push parents a prompt to report which positive T1D behaviors their adolescent has engaged in. The app will generate weekly summary reports of each adolescent's most frequent strength behaviors, and parents will be reminded via the app to praise their adolescent for those patterns. Second, this intervention will be pilot tested with 82 families; parents will be randomized to an intervention or a control condition. Participants in the intervention condition will use the app for 3-4 months and provide feedback, and control participants will receive usual care and will not use the app. The main goal is to determine how often and in what ways families use the app, whether they like it, and to obtain suggestions for improvement. Trends for impact on important diabetes outcomes, such as quality of parent-adolescent relationships, T1D treatment adherence, and glycemic control will also be evaluated. Data - including questionnaires, adherence data from blood glucose meters, and glycemic control biomarkers from a blood draw - will be collected at baseline and again 3-4 months later. The results of this pilot study will help refine the intervention so that it can be evaluated in a fullscale randomized controlled trial. Ultimately, the goal of this research is to validate brief, convenient, and helpful tools that families of all adolescents with T1D can use to strengthen positive family teamwork and ultimately promote optimal diabetes health outcomes.

Feasibility of Study Design - Recruitment Rate
Recruitment data measured by percent of recruited families that enrolled in study.
Time frame: Immediately following enrollment (baseline timepoint)
Feasibility of T1Doing Well App - Engagement With App At Least Twice A Week
Feasibility of the app measured by percentage of participants that engaged with or used the app at least twice a week during the intervention period.
Time frame: 3-4 months after enrollment (follow-up timepoint)
Acceptability of T1Doing Well App (Survey)
Participants in the intervention arm completed the Usefulness, Satisfaction, and Ease of Use Questionnaire (USE), a measure of the users' perceived usefulness of, satisfaction with, and ease of use of a particular technology. The item scale ranges from the minimum to maximum possible score is 1-7, with a higher score representing a better outcome. Acceptability measured as percentage of participants who selected a score of at least 4 (out of 7) on the item "I am satisfied with it," indicating it was at least somewhat acceptable.
Time frame: 3-4 months after baseline (follow-up timepoint)
Acceptability - Number of Participants That Felt The Intervention Was Well-Received
The number of participants that felt the intervention was well-received was collected for Adolescents and Parents. To determine if the intervention was well-received, verbal responses from qualitative interviews with were coded for types of participant feedback by the study team. We coded these data qualitatively and classified them as Positive, Negative, or Neutral. Positive responses indicate the intervention was well-received.
Time frame: 3-4 months after baseline (follow-up timepoint)
Adherence to Diabetes Regimen (Objective) - Blood Glucose Monitoring Frequency
Objective measurement of adherence to diabetes regimen measured by blood glucose monitoring frequency (a well-accepted surrogate of overall adherence), obtained via blood glucose meter downloads. The average daily frequency was calculated over the 14 days prior to the assessment at the baseline visit.
Time frame: 3-4 months after baseline (follow-up timepoint)
Glycemic Control - HbA1c
At the time of this study, the American Diabetes Association generally recommended an HbA1c target of \<7.0% (it was \<7.5% at the time this study took place, for individuals younger than 18 years. The especific target varies depending on the individual). The DCA 2000 HbA1c Analyzer (Siemens-Bayer) was used for point of care HbA1c analysis, it has an analytical measurement range for HbA1c of 2.5% to 14.0%. HbA1c values are collected via fingerstick and blood assay at routine diabetes care visits and values were extracted from the medical record at each clinic visit during the study period.

Item scale ranges from minimum to maximum score of 1-5 for each item, with a higher score indicating a better outcome. Intervention process from baseline to follow-up was analyzed using a general linear mixed model, using the item "How often does he/she praise you for doing well?" Time since first baseline clinic visit was computed and analyzed using a mixed model with time, arm, and the time-arm interaction term.
