A study of U.S. first-year students shows that what parents communicate about heavy drinking before and during college can shape alcohol use patterns, particularly among those who join fraternities or sororities.

A recent survey of U.S. college students found that high parental permissiveness toward heavy episodic drinking (HED) is strongly linked to elevated alcohol use among Greek-affiliated first-year students. The detailed report, published in the journal Behavioral Sciences, highlights how parent attitudes and Greek membership jointly shape drinking outcomes.
Heavy Episodic Drinking as a Public Health Threat
Heavy drinking among college students is a major U.S. public health concern. Heavy episodic drinking (4+ drinks for females; 5+ for males on one occasion) is associated with increased risks of depression, injury, sexual assault, academic decline, alcohol use disorder, and overdose, contributing to an estimated 1,500 student deaths annually. The transition to college brings reduced parental oversight and new social pressures, contributing to higher vulnerability to alcohol misuse.
Greek-Affiliated Social Environments Amplify Drinking Behaviors
Fraternities and sororities are consistently linked to higher alcohol use due to both selection effects (students with risk factors choosing Greek life) and socialization effects (drinking norms within Greek settings). Evidence shows that student drinking habits are shaped not only by peers but also by perceptions of adult attitudes, especially parental approval or disapproval of alcohol.
Survey Design: Parent–Student Dyads Tracked Into College
Researchers surveyed 294 parent–student dyads at a large U.S. public university. Assessments were conducted in the spring of senior year (baseline) and again 1–2 months into the first semester of college (Time 2). Models adjusted for baseline drinking, gender, race, and first-generation status to isolate the effects of parental permissiveness and Greek affiliation.
Greek Students Report and Receive Higher Parental Permissiveness
Parents of Greek-affiliated students reported significantly more permissive attitudes toward heavy episodic drinking compared with parents of non-Greek students in both high school (M = 1.53 vs. 1.24, p < 0.001) and college (M = 1.78 vs. 1.28, p < 0.001). Greek students also perceived their parents as more permissive at both time points. These perceptions matter; Greek affiliation and perceived permissiveness were associated with higher alcohol use (RR = 1.94 and 1.18) and higher rates of HED (RR = 2.32 and 1.49).
Peer Norms Weaken Parental Influence Within Greek Settings
The interaction between Greek affiliation and perceived parental permissiveness significantly predicted general alcohol use frequency (β = –0.25, p = 0.013), but not HED frequency. This indicates that, even when parents appear permissive, peer norms in Greek organizations often dominate and weaken parental influence, shaping drinking patterns through social reinforcement.
Parent–Student Communication Gaps Increase Drinking Risk
The survey highlights increasing parental permissiveness during the transition into college for both parents (t = 2.68, p = 0.008) and students (t = 3.61, p < 0.001). However, the correlation between parents’ actual permissiveness and students’ perceptions was low (r = 0.21–0.27), revealing substantial communication gaps. These gaps suggest opportunities for parent-based normative feedback interventions, which previous research shows can reduce drinking when parents clearly communicate zero-tolerance expectations.
Familial Selection Patterns and Implications for Prevention Programs
Greek-affiliated students often originate from families with pre-existing permissive alcohol attitudes, reinforcing selection into social networks that encourage drinking. Perceived parental permissiveness remained a significant risk factor for both Greek and non-Greek students even after controlling for Greek affiliation. These insights point to the need for targeted interventions, especially parent-based strategies, to reduce drinking among high-risk first-year students.
