MiSSION STRONG - Preventing AOS Misuse in the National Guard

National Guard members, especially those who have been combat-deployed, are at high risk for developing alcohol- and prescription-related drug problems. The use of novel Web-based interventions combined with either Web-based boosters or Peer support sessions, may have a major public health impact for the National Guard by reducing hazardous use of alcohol of prescription drugs. The aims of the study are to develop, refine and test tailored motivational Brief Interventions (BIs) with varied continuing booster reinforcements (Web vs. Peer) and to conduct a randomized controlled trial comparing the efficacy of these BIs (W+W; W+P) to usual care on subsequent alcohol/drug consumption and consequences, including injury, mental and physical-health functioning, and HIV risk behaviors at 4-, 8-, and 12-months post-enrollment.
