Contrary to our hypothesis, parental alcohol problems did not have a direct association with the likelihood of dating several people (p = 0.78). However, parental alcohol problems did have indirect effects on the likelihood of dating several people via the deviance proneness pathway (indirect effect: B = 0.06, p < 0.01, 95% CI [0.035, 0.093]). As hypothesized, parental alcohol problems predicted higher levels of conduct problems (p < 0.01), and higher conduct problems predicted a higher likelihood of dating several people (p < 0.01). Furthermore, dating several people was associated with higher alcohol use (p < 0.01), and was part of an indirect effect from parental alcohol problems to alcohol use via the deviance proneness pathway (indirect effect: B = 0.006, p = 0.01, 95% CI [0.002, 0.012]). Parental alcohol problems also had an indirect effect on the likelihood of dating several people via the positive affect regulation pathway (indirect effect: B = 0.02, p < 0.01, 95% CI [0.009, 0.039]). Parental alcohol problems predicted higher positive urgency (p < 0.01), and higher positive urgency predicted a higher likelihood of
