Media literacy intervention efficacy literature has focused on media-relevant (e.g., knowledge and realism) and behavior-relevant outcomes (e.g., attitudes and behaviors), without much attention paid to interpersonal communication outcomes. This project examined interpersonal communication after participation in two versions (analysis plus analysis and analysis plus planning) of the Youth Message Development (YMD) intervention, a brief media literacy curriculum targeted at preventing high school student alcohol use. Participants attended a 75-mins media literacy YMD workshop and completed a delayed posttest questionnaire 3 to 4 months later. Overall, 68 % participants replied affirmatively to interpersonal communication about the YMD intervention. Communication about the workshop moderated the effects of the type of workshop (analysis plus analysis or analysis plus planning) on self-efficacy to counter-argue (but not critical thinking). Interpersonal communication moderated the effects of the YMD intervention on self-efficacy to counter-argue, thereby signaling the importance of including interpersonal communication behaviors in intervention evaluation.

Rates of youth alcohol use in the USA exceed rates of youth tobacco or drug use [2] and remain high despite the adverse physical, social, legal, and emotional consequences including approximately 4700 deaths [3], physical and sexual assaults, higher risk for suicide and homicide, increased risk for illicit drug abuse, and higher risk of involvement in alcoholrelated car crashes [4,5].The 2011 Youth Risk Behavior Survey revealed that 39 % of high school students report alcohol consumption and 22 % report binge drinking in the last 30 days [6]. Recent reports from the 2012 Monitoring the Future study clearly document that although alcohol use among adolescents dropped significantly in the last 5 years, they still use at unacceptably high levels. For instance, 3.6 % of 8th graders, 14.5 % of 10th graders, and 28.1 % of 12th graders in 2012 reported getting drunk in the past month [7]. These statistics suggest a need for novel efforts to prevent underage drinking and encourage healthier decisions regarding alcohol use. Thus, it is imperative to develop and deliver interventions that prevent alcohol use.Intervention approaches to prevent underage drinking utilize two primary avenues for change: efforts to change the adolescent and efforts to change the adolescent's environment [2]. Intervention approaches to change adolescent behaviors include provision of knowledge, skills, and/or motivation to change adolescent beliefs, attitudes, norms, and intentions. On the other hand, intervention approaches to change the adolescent's environment seek to reduce opportunities for underage drinking by enforcing legislation for minimum age re...
