Protective behavioral strategies (PBS), or harm-reduction behaviors that can potentially reduce alcohol consumption or associated problems, have been assessed in varied ways throughout the literature. Existing scales vary in focus (i.e., broad vs. narrow), and importantly, in response options (i.e., absolute frequency vs. contingent frequency). Absolute frequency conflates PBS use with number of drinking occasions, resulting in inconsistencies in the relationship between PBS use and alcohol outcomes, whereas contingent frequency is less precise, which could reduce power. The current study proposes the use of absolute frequencies to maximize precision, with an adjustment for number of drinking days to extricate PBS …

Objective: While college alcohol misuse remains a pervasive issue, individual-level interventions are among the most efficacious methodologies to reduce alcohol-related harms. Growth mixture modeling (GMM) was used as an exploratory moderation analysis to determine how many types of college drinkers exist with regard to intervention efficacy over a 12-month period.
Method: Data from 3 randomized controlled trials were combined to yield a sample of 1,040 volunteer and mandated college students who were given 1 of 3 interventions: a brief motivational intervention, Alcohol Edu for Sanctions, or Alcohol 101 Plus. Participants were assessed at baseline, and 1, 6, and 12 months …
