Reducing substance involvement in college students: a three-arm parallel-group randomized controlled trial of a computer-based intervention

Abstract

The prevalence of alcohol and other drug use is high among college students. Reducing their consumption will likely be beneficial for society as a whole. Computer and web-based interventions are promising for providing behaviorally based information. The present study compared the efficacy of three interventions (computerized screening and motivational intervention [ASSIST/MBIc], non-computerized screening and motivational intervention [ASSIST/MBIi], and screening only [control]) in college students in Curitiba, Brazil. A convenience sample of 458 students scored moderate and high risk on the ASSIST. They were then randomized into the three arms of the randomized controlled trial (ASSIST/MBIc, ASSIST/MBIi [interview], and assessment-only [control]) and assessed at baseline and 3 months later. The ASSIST involvement scores decreased at follow-up compared with baseline in the three groups, suggesting that any intervention is better than no intervention. For alcohol, the specific involvement scores decreased to a low level of risk in the three groups and the MBIc group showed a positive outcome compared with control, and the scores for each question were reduced in the two intervention groups compared to baseline. For tobacco, involvement scores decreased in the three groups, but they maintained moderate risk. For marijuana, a small positive effect was observed in the ASSIST/MBIi and control groups. The ASSIST/MBIc may be a good alternative to interview interventions because it is easy to administer, students frequently use such computer-based technologies, and individually tailored content can be delivered in the absence of a counselor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
