Randomized trial comparing computer-delivered and face-to-face personalized feedback interventions for high-risk drinking among college students

摘要

This study evaluated the efficacy of two brief personalized feedback interventions (PFIs) using identical feedback and motivational interviewing strategies aimed at reducing alcohol consumption and alcohol-related problems to two control conditions among a sample of high-risk drinking college students. Students (N = 152) were randomly assigned to a computer-delivered PFI with a video interviewer, a face-to-face PFI with a live interviewer, a comprehensive assessment condition, or a minimal assessment-only condition. At 10 weeks posttreatment, the face-to-face PFI significantly reduced weekly drinking quantity and peak and typical blood alcohol concentration compared with the comprehensive assessment and minimal assessment-only conditions (d values ranged from 0.32 to 0.61). No significant between-group differences were evidenced for the computer-delivered PFI condition, although effect sizes were comparable to other college drinking studies using computer-delivered interventions (d values ranged from 0.20 to 0.27). Results provide further support for the use of a face-to-face PFI to help reduce college students' alcohol consumption and suggest that a video interviewer in the context of a computer-delivered PFI is likely a helpful but not necessarily a complete substitute for a live interviewer.
