Digital Exercise for Middle-Aged Adults With Type 1 Diabetes and Other Absolute Insulin Deficiency Diabetes

Not Applicable

Completed

Conditions: Type 1 Diabetes
Latent Autoimmune Diabetes in Adults
Pancreatitis

Brief Summary: The challenges of living with type 1 diabetes often stand in the way of getting enough exercise. Continuous blood sugar monitoring has revolutionized type 1 diabetes care but remains underutilized to sustainably support exercise and related behaviors. This research will develop a mobile application that delivers personalized encouragement and data-driven health insights based upon patterns in blood sugar, exercise, mood, and sleep, to assist people with type 1 diabetes in exercising more frequently and confidently.

Primary Outcome Measures

Name	Time	Method
Feasibility of Usage	4 weeks	Minutes of using application to exercise. 0 minutes/week is the lowest value, 150 minutes/week meets clinically recommended amounts.
Acceptability	4 weeks	Likert-style survey of participant satisfaction. Responses are on a scale from 1 (very dissatisfied) to 5 (very satisfied)
Accuracy	4 weeks	Accuracy to predict lapses in exercise behavior ahead of time. 50% accuracy is the lowest possible value (ie, equivalent to random guessing), 80% accuracy is the goal of the study, and 100% accuracy would be the highest possible accuracy. This is the single outcome of a regression analysis across the entire sample. Being a single outcome, there is no measure of dispersion.

Secondary Outcome Measures

Name	Time	Method
Motivation States for Physical Activity	6 weeks	Scale name: Cravings for Rest and Volitional Energy Expenditure (CRAVE) Construct: Transient state motivation for physical activity Scale ranges: 0 (not at all) to 100 (more than ever). Higher values represent a better outcome.
Moderate to Vigorous Physical Activity	6 weeks	Minutes of moderate to vigorous physical activity registered by hip accelerometer. 0 minutes/week is the lowest value, 150 minutes/week meets clinically recommended amounts.
Interview Themes	6 weeks	Qualitatively-identified determinants and sequalae of motivation states for physical activity
