Table 3.

Treatment fidelity comparison of training in single-intervention groups (FAST, SAM) versus the combined group (FAST+SAM). Only one between-group difference was found: participants in the FAST+SAM group wore their Fitbits significantly fewer days per week during training than those in the SAM group. (Abbreviations: SE = standard error; N/A = not applicable)

TREATMENT FIDELITY COMPARISON OF TRAINING, mean (SE)
	FAST alone	SAM alone	FAST+SAM	p-value
Sessions attended	26.07 (0.87)	24.48 (0.77)	25.48 (1.06)	p = 0.45
Mean treadmill minutes walked/session	28.51 (0.29)	N/A (no treadmill used in SAM intervention)	28.33 (0.32)	p = 0.68
% of treadmill minutes in THR range	53.80 (2.48)	N/A (no treadmill used in SAM intervention)	55.59 (2.61)	p = 0.62
Mean Fitbit-wearing days/week	N/A (no step activity monitoring in FAST intervention)	4.40 (0.08)	3.96 (0.11)	p = 0.002
% of Fitbit-wearing days on which step goal was achieved	N/A (no step activity monitoring in FAST intervention)	69.18 (2.63)	65.06 (3.06)	p = 0.31
