^aNonadherence to DSW defined as one or more days without a weight measurement (from wireless scales). Nonadherence to DAT was defined as one or more days without activity tracking (<1000 total steps/day).

^bModel for self-weighing reflects 2,858 weight measures.

^cModel for physical activity tracking reflects 1,341 bouts of physical activity.
