Hierarchical multiple regression analysis predicting likelihood of having sex without a condom (N = 180)

Variable	B (SE)	β	R² change
Step 1			.27
Gender	0.77 (0.29)	0.19^†
Impulsivity	0.44 (0.32)	0.10
Heavy drinking	0.18 (0.12)	0.10
Alcohol expectancies	0.41 (0.17)	0.18^†
Number sex partners	0.03 (0.01)	0.18^†
Condom use	−0.28 (0.09)	−0.22^†
Step 2			.02
Receive alcohol contrast	0.37 (0.19)	0.13^*
Expect alcohol contrast	0.01 (0.16)	0.00
Step 3			.23
Sexual arousal	0.15 (0.07)	0.12^*
Partner trust	0.05 (0.08)	0.04
Negative consequences	−1.41 (0.55)	−0.15^*
Worried neg. conseq.	−0.28 (0.08)	−0.22^†
Irresponsible sex	−0.16 (0.09)	−0.13
Mad at self	−0.19 (0.07)	−0.20^†
Step 4			.01
Expectancies × Receive Alcohol	−0.05 (0.22)	−0.01
Expectancies × Expect Alcohol	0.29 (0.20)	0.11
Gender × Receive Alcohol	−0.21 (0.29)	−0.06
Gender × Expect Alcohol	−0.01 (0.30)	0.00

Notes: Worried neg. conseq. = worried about negative consequences. For gender, positive beta weights are associated with being male. For the receive alcohol contrast, positive beta weights arc associated with being in the alcohol condition; for the expect alcohol contrast, positive beta weights are associated with being in the placebo condition.
