High-risk drinking and the associated consequences continue to be significant problems among college students. Among the many consequences of this risky behavior are impaired driving and impaired passenger fatalities. These concerns are further magnified by reports showing: 1) younger drivers are overrepresented in fatal crashes involving impaired drivers; 2)\~1 in 6 fatalities are passengers (riders with the impaired drivers; RWID); and 3) although over 1.3 million drivers in the U.S. are arrested for impaired driving annually, they only represent 1% of the estimated 121 million self-reported episodes of impaired driving each year. Despite the benefits noted for the PBI, the investigators' recent NIAAA funded research examining parenting throughout college identified associations between specific parenting behaviors and risky drinking and consequences among students that are not adequately addressed. This research revealed several important trends: 1) many parents allow their teens to drink alcohol in an attempt to take the mystery away and provide opportunities to teach them safer drinking practices; 2) this "parental permissiveness" toward underage drinking, even though it was intended to be protective by parents, had the opposite effect and was significantly associated with increased risky drinking and consequences throughout college even when taking into account other critical factors (e.g., peer norms); 3) even small increases in parental permissiveness translated into students experiencing 4-5 more consequences per year; and 4) the effects of this parental permissiveness was not attenuated by other positive parenting behaviors (e.g., communication, monitoring, modeling). In response to these findings and the initial pilot study showing parents were initially reluctant to change their permissiveness when simply provided with the information about how it was associated with risky student drinking, the investigators embarked on a new endeavor in college student parent intervention research. The investigators developed a brief 15-20 minute intervention (P-Chat) that uses principles of Motivational Interviewing (MI) to reduce defensiveness and modify parents' motives (and behaviors) to change parental permissiveness, and in turn, reduce students' risky drinking and consequences. The investigators have also conducted a pilot randomized controlled trial (RCT) study to demonstrate ability to implement the P-Chat with fidelity; modify parents' willingness to change; and change parents' permissive behaviors. The pilot data provides evidence that the P-Chat intervention has the potential to substantially improve the public health impact of PBIs. The proposed research will examine the P-Chat as a stand-alone intervention and also as an add-on in combination with the original PBI to evaluate the best practice for implementation in a RCT using a rigorous study design.

The design is a four-arm randomized control trial with 4 waves of data collection (P-Chat, P-Chat+, PBI Only, and assessment only control). The study will enroll an ethnically diverse sample of 900 parent-student dyads. Students will complete assessments of all the primary, secondary, and tertiary outcomes at four times: pre-intervention baseline and 3-month, 6-month, and 9-month follow-ups. To maximize the diversity of the sample, the investigators are oversampling for 30% racial/ethnic minorities, free of sample bias.
