Item A randomized controlled trial of a web-based, personalized normative feedback alcohol intervention for young-adult veterans(Journal of Consulting and Clinical Psychology, 03/13/17) Pedersen, Eric R.; Parast, Layla; Marshall, Grant N.; Schell, Terry L.; Neighbors, ClaytonObjective: Young adult American veterans are at-risk for problematic alcohol use. However, they are unlikely to seek care and may drop out from lengthy multicomponent treatments when they do get care. This randomized controlled trial tested a very brief alcohol intervention delivered over the Internet to reach the population of young adult veterans to help reduce their drinking. Method: Veterans (N=784) were recruited from Facebook and randomized to either a control condition or a personalized normative feedback (PNF) intervention seeking to correct drinking perceptions of gender-specific veteran peers. Results: At immediate post-intervention, PNF participants reported greater reductions in their perceptions of peer drinking and in intentions to drink over the next month compared to control participants. At one-month follow-up, PNF participants reduced their drinking behavior and consequences to a significantly greater extent than controls. Specifically, PNF participants drank 3.4 fewer drinks per week, consumed 0.4 fewer drinks per occasion, binge drank on 1.0 fewer days, and experienced about 1.0 fewer consequences than control participants in the month after the intervention. Intervention effects for drinks per occasion were most pronounced among more problematic drinkers. Changes in perceived norms from baseline to one-month follow-up mediated intervention efficacy. Conclusions: Though effects were assessed after only one-month, findings have potential to inform broader, population-level programs designed for young veterans to prevent escalation of drinking and development of long-term alcohol problems. Given the simplicity of the PNF approach and ease of administration, this intervention has the potential for a substantial impact on public health.Item Young adult veteran perceptions of peers' drinking behavior and attitudes(Psychology of Addictive Behaviors, 2016-02) Pedersen, Eric R.; Marshall, Grant N.; Schell, Terry L.; Neighbors, ClaytonSocial norms-based interventions have shown promise in reducing drinking behavior and resulting consequences in young adults. Although most research has focused on young civilians (i.e., college students), some studies have investigated social norms-based interventions with active duty military and veteran samples. Yet, research has not yet determined how to maximize the effectiveness of social norms-based intervention in this heavy drinking population. As an initial step toward this goal, the current study utilized a community sample of 1,023 young adult veterans to examine: (1) whether veteran perceptions of the drinking behavior of their veteran peers differ from their perceptions of civilian drinking behavior, (2) whether perceptions of specific veteran groups differ from actual drinking behavior of veterans within those groups, (3) what levels of specificity in reference groups (same-gender civilians, same-branch veterans, same-gender veterans, or same-branch-and-same-gender veterans) are most strongly associated with veterans’ own drinking, and (4) whether perceptions about others’ attitudes toward drinking also contribute independently of perceived behavioral norms to veteran drinking. Findings indicated that participants perceived that other veterans drank more than civilians and that veteran groups drank more than veterans in the sample actually drank. Veteran-specific perceived behavioral norms were similar in their associations with drinking outcomes, whereas same-gender civilian perceived behavioral norms exhibited little or no associations with drinking. Veteran-specific perceived attitudinal norms exhibited little or no association on drinking behavior after controlling for perceived behavioral norms. These findings can be used to inform the development of social norms interventions for young adult veterans.
