Following LA to heroin, rats were housed in either non-EE or EE conditions.

Responders were re-randomized to continued or minimized condition; non-responders were re-randomized to continued or intensified condition (2nd stage; weeks 5–8). Analyses examined outcomes from the initial randomization; and comparisons between responders and non-responders on primary (alcohol consumption, aggression), secondary (alcohol consequences, violence consequences) and exploratory (alcohol misuse, victimization, drug use, drug consequences) outcomes.</div></div><div><h3>Results</h3><div>There were no significant differences in outcomes between 1st stage boosters or 2nd stage boosters for non-responder or responder groups. However, significant changes over time were observed across all participants, with the odds of abstaining from alcohol increased at 4 (OR 3.97, 95 % CI 2.46–6.41) and 8-months (OR 4.36, 95 % CI 2.11–9.02), while the odds of aggression (OR 0.39, 95 % CI 0.16–0.94) decreased at 8-months; significant decreases were also observed for other outcomes.</div></div><div><h3>Conclusions</h3><div>Findings support the promise of digital health interventions for youth with binge drinking and aggression.</div></div>","PeriodicalId":11322,"journal":{"name":"Drug and alcohol dependence","volume":"270 ","pages":"Article 112615"},"PeriodicalIF":3.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
