Relationships between ASI and RASB outcomes at an individual level, gender effects, and gender X ASI interactions

Outcome Variable	Past year number of regular partners	Past year number of casual partners	Past year sex behavior under influence of drugs/alcohol	Lifetime number of casual partners	Lifetime number of regular partners	Early pregnancy
ASI_IND	.12 (.05)^**	.24 (.05)^***	.25 (.05)^***	.02 (.07)	.03 (.06)	1.18 (.15)^***
Gender	−.11 (.06)^*	.45 (.06)^***	.30 (.07)^***	.25 (.07)^***	.02 (.05)	−.73 (.15)^***
ASI_IND X Gender	−.15 (.10)	.58 (.11)^***	.30 (.11)^**	.54 (.10)^***	.18 (.09)	.37 (.31)
Sexual opportunity	N/A	N/A	N/A	.32 (.04)^***	.45 (.04)^***	N/A

Note: ASI, adolescent sexual initiation; early pregnancy: ASI_IND refers to the fact that this is an individual-level regression (using all participants); early pregnancy, having been pregnant or having made someone pregnant before age 20; sexual opportunity: current age - time at initial sexual experience. All variables but early pregnancy (which was categorical) were z-scored. Unstandardized regression weights [B(SEs)] are presented. The gender effect in early pregnancy is in the same direction as all other gender effects (higher RASB in men), despite the opposite sign.
