Note. IPT = interpersonal trauma. Bold type indicates p < .05. Bold italic type indicates p < .01. Model 1 corresponds to the model examining the main effects of relationship satisfaction and IPT on alcohol use. Model 2 corresponds to the model examining the two-way interactions between relationship satisfaction and IPT to predict alcohol use. Model 3 corresponds to the model examining the three-way interactions between relationship satisfaction, IPT, and sex to predict alcohol use. Relationship satisfaction was standardized. Alcohol use was log-transformed and added to a constant of one.
