About this trial
Type 1 diabetes (T1D) affects approximately 2 million Americans, and only 2 in 8 young adults ages 18-31 years achieve glycemic targets (glycated hemoglobin A1C \<7.0%). Achieving glycemic targets is associated with reduced risk of micro-and macrovascular complications. Sleep deprivation leads to impaired glucose tolerance and insulin sensitivity in adults without chronic conditions and with T1D. Promoting sleep in laboratory and natural environments contributes to improvements in insulin sensitivity, glucose levels, and distress symptoms in young adults without chronic conditions and more time in range in adolescents with T1D. Multiple dimensions of sleep health (alertness, timing, efficiency, and sleep duration) are associated with better achievement of glycemic targets in adults with T1D. Therefore, sleep health dimensions are appropriate therapeutic targets to improve glucoregulation and other diabetes self-management outcomes in this population.
Our primary objective is to evaluate the immediate and short-term effects of a 12-week CB-sleep intervention compared to enhanced usual care (time balanced attention control) on actigraphy- and self-report derived sleep health dimensions and diabetes self-management outcomes (glycemia and distress symptoms) over 9-months (Stage II of the NIH Model for Behavior Change, ORBIT phase III). CB-sleep is guided by principles and practices from motivational interviewing and the Transtheoretical Model of Behavior Change with interactive stage-matched sessions.

Treatments tested in this trial
CB Sleep
BehavioralThe CB-sleep intervention is a cognitive behavioral intervention guided by principles and practices from motivational interviewing and the psychology of behavior change, primarily drawing on self-efficacy and action planning theory. The goals of CB-sleep are for participants to achieve adequate sleep duration (7-9 hours per night), adequate sleep efficiency (≥ 85%), and regular sleep timing (\<60-minute differences in bed and wake times). The intervention components include improving sleep knowledge (hygiene), developing a nightly routine, addressing competing activities, modifying environmental conditions, lifestyle (avoiding caffeine and vigorous exercise before bed), technology (limiting or avoiding screens for at least one hour before bed), basic stress-management (progressive muscle relaxation and guided imagery), and self- monitoring.
Treatment groups
Trial outcomes
Primary outcomes
Multidimensional sleep health composite score
The multidimensional sleep health composite score will measure sleep regularity, satisfaction, alertness, timing, efficiency, and duration of sleep. The total possible score range is 0-6 with higher scores indicating higher or better sleep health.
Glycated hemoglobin (HbA1C)
Changes in glycemia will be measured by glycated hemoglobin (HbA1C) at baseline, 3, 6 and 9 months.
Secondary outcomes
Glucose variability
% coefficient of variation will be measured by Continuous glucose monitor (CGM) or glucose meter
Time in range (70-140 mg/dL)
Time in rage for glycemic control (70-140 mg/dL) will be measured by Continuous glucose monitor (CGM) or glucose meter
General distress symptoms
PROMIS v1.0 Emotional Distress (Cronbach's α = 0.95, ICC 0.69 to 0.88), With a standardized normative T-score of 50 and a standard deviation of 10, T-scores \<55 would translate as normal; 55-60 as mild; 60-70 as moderate, and ≥70 as severe distress
Diabetes distress symptoms
Diabetes Distress Scale (Cronbach's α = 0.88 to 0.93, ICC 0.44 to 0.64), Average score of \< 2.0 = reflects little or no distress Average score between 2.0 and 2.9 = reflects moderate distress, Average score \> 3.0 = reflects high distress, A total or subscale score \> 2.0 (moderate distress) is considered clinically significant.
