Conditions: Type1diabetes

Interventions: Behavioral: Positive Psychology Intervention
Behavioral: Education

Registration Number: NCT02984709

Lead Sponsor: Vanderbilt University

Brief Summary: The treatment regimen for type 1 diabetes is complex and demanding, and many adolescents have problems with adherence. The proposed study will pilot test a positive psychology intervention for adolescents with type 1 diabetes aimed at improving adherence to treatment based on feedback from the first iteration of the intervention. The potential benefits include helping adolescents achieve better glycemic control, thereby reducing the health risks and complications associated with diabetes.

Detailed Description: The proposed study has the potential to improve adherence to the diabetes regimen in adolescents with type 1 diabetes without compromising their quality of life. The potential benefits include helping adolescents achieve better glycemic control, thereby reducing the health risks and complications associated with diabetes.

The investigators will use a positive psychology framework, which emphasizes positive emotions and strengths rather than problems, to promote adherence.

Positive affect, defined as feelings that reflect pleasurable engagement with the environment (e.g., happy, cheerful,proud), have been linked with favorable health outcomes and increased adherence to medical regimens. Further, positive affect has been shown to increase people's ability to use complex coping strategies. Randomized controlled trials of positive psychology interventions have been shown to successfully increase adults' adherence to medication and physical activity recommendations. However, no studies have examined the effects of positive psychology interventions on adherence behaviors in pediatric populations. Our ongoing work suggests that positive affect in adolescents with type 1 diabetes is related to greater use of adaptive coping strategies, lower levels of family conflict, and fewer depressive symptoms, and demonstrates that a positive psychology intervention has the potential to induce positive affect in adolescents. The investigators propose to pilot test a positive psychology intervention for adolescents with type 1 diabetes. This low-cost, innovative intervention is designed to induce positive affect in adolescents (age 13-17) through tailored exercises in gratitude and self-affirmation. The investigators will also promote positive parental involvement by asking caregivers to provide positive affirmation statements to adolescents. Finally, the investigators will explore the use of technology by delivering the intervention to adolescents and sending reminders to caregivers via text message using the Twilio/REDCap system.

Blood glucose monitoring is one of the best indicators of adherence to the recommended treatment regimen for type 1 diabetes, and frequency of blood glucose monitoring is strongly related to glycemic control. Further, frequency of blood glucose monitoring has been shown to decrease with age in adolescents, and parental reminders to check blood glucose are often a source of conflict between adolescents and their parents. Therefore, blood glucose monitoring represents a specific behavior that may be the best target for adherence interventions in adolescents with type 1 diabetes.

Thus, the specific aims are as follows:

Aim 1: Adapt a positive psychology intervention for adolescents (age 13-17) with type 1 diabetes designed to increase the frequency of blood glucose monitoring. Aim 2: Evaluate the feasibility, acceptability, and preliminary efficacy of a positive psychology intervention for adolescents with type 1 diabetes and their caregivers delivered by text message with the Twilio/REDCap system. The primary outcome is glycemic control, and secondary outcomes include positive affect, coping, adherence (i.e., frequency of blood glucose monitoring), family conflict, and quality of life.

Arm && Interventions

Group	Intervention	Description
Positive Psychology Intervention	Positive Psychology Intervention	The text message group will receive the intervention components via text message. They will be instructed to think about things that make them feel good when they are struggling with diabetes management (i.e. gratitude). Also they will be instructed to think about a positive value when they are in a situation that makes it hard to check their blood sugar (i.e. Self-Affirmation). Additionally, to induce positive mood they will be texted gift cards codes valued at $5.00. Further, caregivers will be asked to provide weekly positive affirmations to their adolescents, focused on non-diabetes strengths. All adolescents will be given developmentally-appropriate diabetes education material at the time of enrollment.
Education Group	Education	The education group will be given developmentally-appropriate diabetes education material at the time of enrollment.

Primary Outcome Measures

Name	Time	Method
Glycemic Control (A1C)	3 months	A1C is the percentage of glycosylated hemoglobin and represents an average of glycemic control over the previous 2-3 months.

Secondary Outcome Measures

Name	Time	Method
Positive Affect	3 months	Positive affect measured using the Positive and Negative Affect Scale for children (PANAS-C). The positive affect scale consists of 15 items, which are summed for a total score, ranging from 15-60. Higher scores indicate higher levels of positive affect.
Frequency of Blood Glucose Monitoring	3 months	Glucometer download to determine frequency of blood glucose checks per day. Higher numbers indicates more frequent blood glucose checks.
Diabetes Family Conflict Scale	3 months	Diabetes-specific family conflict was measured with the Revised Diabetes Family Conflict Scale (DRCS), which consists of 19 items regarding how much adolescents and parents argue about diabetes management tasks. Scores range from 19 to 57, and higher scores indicate greater family conflict.
Secondary Control Coping	3 months	Responses to Stress Questionnaire measures coping with diabetes-related stress. Three factors of coping are measured: primary control coping, secondary control coping,and disengagement coping. A ratio score is calculated to determine the ratio of each type of coping in relation to total coping, ranging from 0.00 to 1.00. Higher levels indicate greater relative use of secondary control coping (e.g., acceptance, distraction, positive thinking).
Disengagement Coping	3 months	Responses to Stress Questionnaire measures coping with diabetes-related stress. Three factors of coping are measured: primary control coping, secondary control coping,and disengagement coping. A ratio score is calculated to determine the ratio of each type of coping in relation to total coping, ranging from 0.00 to 1.00. Higher levels indicate greater relative use of disengagement control coping (e.g., avoidance, denial).
Diabetes-Specific Quality of Life	3 months	Pediatric Quality of Life Diabetes-Specific Module (PedsQL) measures quality of life. A mean scaled score is calculated, ranging from 0-100, with higher values indicating better quality of life.
Primary Control Coping	3 months	Responses to Stress Questionnaire measures coping with diabetes-related stress. Three factors of coping are measured: primary control coping, secondary control coping,and disengagement coping. A ratio score is calculated to determine the ratio of each type of coping in relation to total coping, ranging from 0.00 to 1.00. Higher scores indicate greater relative use of primary control coping (e.g., problem solving, emotional modulation).
Self Care Inventory	3 months	The Self Care Inventory measures adherence to the recommended diabetes treatment regimen. Adolescents and parents report on the adolescents' self-care behaviors. Items are summed for a total score, ranging from 7-35. Higher scores indicate higher levels of adherence.
