Two-Step Linear Regression Analysis for Predicting 12-Month Physical Activity

Step 1			Overall model fit: F (4,23) = 3.563, p = .021

	Variable		B	SE B	β	p
	Constant		9.15	46.30
	Baseline PA min		−0.66	1.09	−0.11	0.549
	6-Month PA min		0.39	0.24	0.30	0.118
	Pre-Task FS		−0.07	15.55	−.001	0.997
	FS		40.97	19.48	0.45	0.047

Step 2		Change in R² < .01	Overall model fit: F (5,22) = 2.748, p = .045

	Variable		B	SE B	β	p-value

	Constant		51.01	171.44
	Baseline PA min		−0.53	1.23	−0.09	0.670
	6-Month PA min		0.36	0.27	0.28	0.191
	Pre-Task FS		−0.41	15.93	−0.01	0.980
	FS		39.90	20.33	0.43	0.063
	RPE		−3.17	12.47	−0.05	0.802

Note. FS = Feeling Scale. RPE = Rating of Perceived Exertion. PA = Physical Activity of at least Moderate-intensity.
