Brief Summary

Mothers of adolescents with type 1 diabetes experience high levels of depressive symptoms, which impair their ability to monitor and manage diabetes treatment effectively. Further, maternal depressive symptoms are one of the strongest predictors of negative outcomes in adolescents, including deteriorating glycemic control, problems with adherence, poorer quality of life, and greater risk for depression. Given that adolescents are a high-risk population for suboptimal glycemic control - with only 17% meeting treatment goals - there is a critical need for novel interventions to improve outcomes in adolescents with T1D. Yet, previous behavioral interventions for youth with diabetes have had only modest effects on glycemic control, and none have directly targeted maternal depressive symptoms.

Building on effective interventions to treat depression in adults, and our own pilot work in this population, the proposed study will use a rigorous approach to evaluate the efficacy of a cognitive-behavioral intervention for mothers of adolescents with type 1 diabetes to promote the use of adaptive coping strategies and positive parenting practices. The aims of this study are to: 1) evaluate the effects of the Communication \& Coping intervention on diabetes-related outcomes; 2) evaluate the effects of the Communication \& Coping intervention on psychosocial outcomes; and 3) explore the differential impact of the intervention across demographic factors. Mothers who are randomized to the Communication \& Coping Intervention will receive individual cognitive-behavioral therapy sessions by phone, as well as access to a Facebook group to augment the material covered in calls and provide social support. Mothers randomized to the Attention Control condition will receive educational materials and phone check-ins, as well as a Facebook group with educational posts. Adolescents and their mothers will be assessed at baseline and again post-intervention, at 3 months, 6 months, and 12 months.

Detailed Description

Mothers of adolescents with type 1 diabetes experience high levels of depressive symptoms, which impair their ability to monitor and manage diabetes treatment effectively. The regimen recommended for type 1 diabetes is complex and demanding, and caregivers - especially mothers - experience stress related to the burden of treatment management. This stress is associated with increased risk for psychosocial problems in caregivers, with rates of clinically significant depressive symptoms evident in up to 61% of parents. Further, maternal depressive symptoms are one of the strongest predictors of negative outcomes in adolescents, including deteriorating glycemic control, problems with adherence, poorer quality of life, and greater risk for depression. Given that adolescents are a high-risk population for suboptimal glycemic control - with only 17% meeting treatment goals - there is a critical need for novel interventions to improve outcomes in adolescents with T1D. Yet, previous behavioral interventions for youth with diabetes have had only modest effects on glycemic control, and none have directly targeted maternal depressive symptoms. Responding to the American Diabetes Association's call to address the psychosocial needs of people with diabetes and their family members, the proposed project has the potential to improve outcomes in both adolescents with type 1 diabetes and their mothers.

Building on effective interventions to treat depression in adults, and our own pilot work in this population, the proposed study will use a rigorous approach to evaluate the efficacy of a cognitive-behavioral intervention for mothers of adolescents with type 1 diabetes to promote the use of adaptive coping strategies and positive parenting practices. The aims of this study are to: 1) evaluate the effects of the Communication \& Coping intervention on diabetes-related outcomes; 2) evaluate the effects of the Communication \& Coping intervention on psychosocial outcomes; and 3) explore the differential impact of the intervention across demographic factors. Mothers who are randomized to the Communication \& Coping Intervention will receive individual cognitive-behavioral therapy sessions by phone, as well as access to a Facebook group to augment the material covered in calls and provide social support. Mothers randomized to the Attention Control condition will receive educational materials and phone check-ins, as well as a Facebook group with educational posts. Adolescents and their mothers will be assessed at baseline and again post-intervention, at 3 months, 6 months, and 12 months. We hypothesize that the adolescents of mothers who receive the intervention will demonstrate improvements in diabetes outcomes (i.e., glycemic control, adherence), as well as psychosocial outcomes (i.e., improved quality of life, fewer depressive symptoms) compared to those in the attention control condition. This approach is innovative by targeting maternal depressive symptoms and the quality of parental involvement in mothers of adolescents with type 1 diabetes.

Arm && Interventions

Group	Intervention	Description
Education & Check Ins	Education & Check Ins	The comparison group receives educational materials on diabetes management and phone calls, as well as access to a secret Facebook group with daily posts on diabetes management.
Communication & Coping Intervention	Communication & Coping Intervention	A cognitive behavioral intervention for mothers of adolescents with type 1 diabetes to improve coping and the quality of parental involvement.

Primary Outcome Measures

Name	Time	Method
Glycemic control (A1C)	3 months	Hemoglobin A1c measured as part of clinic visit

Secondary Outcome Measures

Name	Time	Method
Mothers' Social Support	3 months	Multidimensional Scale of Perceived Social Support (MSPSS) is a 12-item scale of social support from family, friends and significant others. A mean total score will be calculated, ranging from 1-7, with higher scores indicating greater perceived social support.
Maternal Symptoms of Anxiety	3 months	Generalized Anxiety Disorder Scale - 7 (GADS-7) consists of 7 items measuring symptoms of anxiety. Scores range from 0-21, and scores of 10 or higher are considered clinically meaningful.
