| Popis: | Rates of drug use among collegiate athletes are high, yet there are few evidence-based interventions for this population. myPlaybook, an online intervention for collegiate athletes, targets multiple predictors of drug use (i.e., norms, positive and negative expectancies about use, and harm prevention intentions).We aimed to optimize modules from myPlaybook.We evaluated modules through three sequential randomized factorial trials, using the Multiphase Optimization Strategy framework. We recruited and randomized 54 (Trial 1), 47 (Trial 2), and 42 (Trial 3) schools and invited all first-year and transfer collegiate athletes to participate. Athletes completed a baseline survey, their randomly assigned modules, and immediate posttest and 30-day follow-up surveys. Across trials, 3,244 (48.8% female), 2,837 (51.9% female), and 2,193 (51.4% female) athletes participated. In Trial 1, we evaluated and revised less effective modules (defined as d0.3-0.4 for targeted outcomes). In Trial 2, we re-evaluated and revised less effective modules. In Trial 3, we re-evaluated the revised modules.Trial 1: All effects were d0.15, so we revised modules to target proximal outcomes (i.e., the hypothesized mediating variables in our conceptual model), rather than specific drug use behaviors. Trial 2: Most effects were d0.3, so we revised all modules. Trial 3: The norms module improved descriptive and injunctive norms (all d0.35). The expectancies module improved alcohol positive expectancies (d = 0.3). The other modules were not effective.After three trials, two myPlaybook modules substantially improved proximal outcomes, increasing the likelihood that the combined intervention will have a meaningful clinical impact on collegiate athletes' drug use.Rates of drug use among collegiate athletes are high, yet there are few evidence-based interventions for this population, and the few existing interventions only address alcohol use. In addition, alcohol and drug use interventions targeting college students are not always as effective or efficient as they could be. Our goal was to strengthen modules from myPlaybook, an online drug use intervention for collegiate athletes as a way to optimize the full intervention package. We conducted three intervention trials. Each trial occurred in separate academic years and included 2,000–3,000 athletes from 40 to 50 colleges and universities. We randomly assigned athletes to receive one or more intervention modules that target known risk factors for drug use (i.e., social norms, expectancies about the effects of drug use, harm prevention strategies, and life skills). We used the results about the effects of each module to improve the module prior to the next trial. After these trials, the revised modules targeting social norms and expectancies about drug use had meaningful effects, increasing the likelihood that the full myPlaybook intervention will lead to clinical reductions in drug use among collegiate athletes. |
