Although the likelihood of drinking was still lowest in two biological married parent families, the gap between teens in cohabiting versus married stepfamilies reduced to nonsignifance (this reduction occurred by controlling for either maternal socialization or drinking [results not shown]) (Model 2b). Maternal support and control both reduced the likelihood of drinking. Maternal drinking was positively associated with adolescent drinking. Relative to occasional drinkers, mothers who never drank had an adolescent who was less likely to drink, too, whereas mothers who drank at least weekly also had a teenager who was more likely to drink. Despite controlling for these factors, the differential between adolescents in cohabiting stepfamilies versus single-mother families persisted.
