Note. N (days) = 8227, N (persons) = 199. Akaike Information Criteria (AIC) = 10987.04, Bayesian Information Criteria (BIC) = 11758.71. Site is coded 0 = [location omitted for blind review], 1 = [location omitted for blind review]. Day of the week and elapsed day are included as covariates but not depicted due to space limitations. Intox = Intoxication, EC = effortful control, Part rel = Partner relationship, RRR= relative risk ratio. Urgency and EC are scaled by a factor of 5. Intoxication and relationship are centered at the person mean. All between-person variables are centered at grand mean. Categories are mutually exclusive. Minimal sex contact category refers to nights that some sexual behavior occurred but no oral sex or intercourse occurred. The oral sex category refers to nights that oral sex but no anal intercourse occurred.
