Youth at risk of physical inactivity may benefit more from activity-related support than youth not at risk

Parameters from each regression model	β (SE)	R² for model
Main effect of risk	-.37 (.17)**	.23**

Main effect of risk	-.33 (.17) **	.24**
Main effect of sibling support	.16 (.12) **
Interaction between risk and sibling support	.21 (.18) **
Main effect of risk	-.25 (.17) **	.33**
Main effect of peer support	.34 (.11) **
Interaction between risk and peer support	.22 (.17) *

Note: † p < .10 * p < .05 ** p < .01
High risk coded as 1, low risk coded as 0.
The beta-weight for risk is slightly different across models because a different source of support was included in each model. The resulting beta weight is the independent effect of risk.
