Stepwise linear regression analyses of independent associations between physical activity and Social Cognitive Theory variables for the fatigued sample with multiple sclerosis (n=108).

Step	Variable	B	SE B	β
*a: MVPA*
Step 1	LL-FDI	0.527	0.136	0.353^*
Step 2	LL-FDI	0.471	0.134	0.315^*
	EGS	0.440	0.171	0.231^*
Note: R² = 0.125 for Step 1; R² = 0.176 for Step 2
*b: GLTEQ*
Step 1	EXSE	0.260	0.062	0.377^*
Step 2	EXSE	0.182	0.071	0.264^*
	LL-FDI	0.407	0.186	0.225^*
Step 3	EXSE	0.131	0.074	0.190
	LL-FDI	0.414	0.183	0.228^*
	EGS	0.454	0.216	0.197^*
Note: R² = 0.143 for Step 1; R² = 0.181 for Step 2; R² = 0.214 for Step 3

Note: MVPA = moderate-to-vigorous physical activity, LL-FDI = Late-Life Function and Disability Instrument, EGS = Exercise Goal-Setting Scale, GLTEQ = Godin Leisure-Time Exercise Questionnaire, EXSE = Exercise Self-Efficacy Scale
