Mechanisms of Behavior Change Within Peer-Implemented Alcohol Interventions.

Objective: Colleges continue to experience a high number of referred students because of campus alcohol violations. Subsequently, there has been a trend to use peer-implemented minimal interventions (PMIs), often using motivational interviewing (MI). However, little is known about how PMIs facilitate behavior change.

Response of heavy-drinking voluntary and mandated college students to a peer-led brief motivational intervention addressing alcohol use.

Little is known about the way in which mandated and heavy-drinking voluntary students comparatively respond to peer-led brief motivational interventions (BMIs) and the mediators and moderators of intervention effects. Research suggests that mandated students may be more defensive due to their involvement in treatment against their will and this defensiveness, in turn, may relate to treatment outcome. Furthermore, it is not clear how mandated and heavy-drinking voluntary students perceived satisfaction with peer-led BMIs relates to treatment outcomes.
