Trial outcomes

Primary outcomes

1

Treatment acceptability

Intervention acceptability will be assessed using the Treatment Evaluation Questionnaire (TEQ) to measure acceptability of the three experimental conditions following the completion of each condition. Scale Range: 0 to 4. Higher scores indicate greater acceptability.

Time frame
2 weeks
2

Changes in Evening Sedentary Screen Time

Minutes per week of screen time after 5p as measured by WatchWell app and activPAL

Time frame
2 weeks
3

Change in evening postprandial glycemic control (5pm - 5am)

Participants will be asked to wear the Dexcom G6 Pro continuous glucose monitor during baseline and experimental conditions. Glycemic control will be calculated by averaging all glucose readings from 5pm - 5am during each of the conditions.

Time frame
2 weeks
