AIBs involve a period of amnesia while the person is conscious and interacting; they may not remember what happened. AIBs are linked to consequences ranging from embarrassment and hangovers to sexual risk and developing alcohol use disorder. Among college students with recent AIBs, one in three drinking days involves this type of blackout—perhaps in part because young adults often do not perceive AIBs negatively. For the study in <i>Alcohol: Clinical & Experimental Research</i>, investigators explored the role of social context (who people drink with) and location (where they drink) in the alcohol-related consequences of AIBs.</p><p>Researchers worked with 175 young adults who had recent histories of regular risky drinking, including AIBs. The participants were mostly White (87%) college students. Over six weekends (Thursday-Saturday social periods), they wore transdermal alcohol sensors and completed morning and evening assessments of their drinking behaviors. They also reported on alcohol-related consequences: positive (e.g., having fun), common negative (e.g., arguing, hangovers), uncommon negative (e.g., unwanted sexual experiences), and alcohol-related problems with impaired control or dependence.</p><p>During the 18 study days, participants reportedly consumed alcohol on an average of nine days. One in three drinking occasions resulted in an AIB; these occasions resulted in more consequences of each type than drinking occasions without AIBs: 15% more positive reports, 205% more common negative consequences, 367% more uncommon negative experiences, and 166% more alcohol-related problems. When participants drank exclusively with family, friends, or partners, those who experienced AIBs reported about 3½ times more common negative consequences and three times as many alcohol-related problems (compared to drinking at similar levels without AIBs). When drinking in someone's home, AIBs were linked to about 4½ times more common negative consequences compared to non-AIB drinking days.</p><p>Social context and location may be particularly important influences when alcohol use involves AIBs. Possibly, young adults are less likely to use protective behavioral strategies when drinking with friends and partners and in private homes than in contexts that feel less safe.

This longitudinal study of adults with AUD examined whether age and race/ethnicity moderated associations between MHG involvement and alcohol outcomes.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Data were from the pooled Peer ALternatives for Addiction 2015 and 2021 Cohorts (<i>N</i> = 1152), which adopted parallel designs and measures. Eligibility criteria included lifetime AUD and past-30-day 12-step and/or second-wave MHG attendance. Participants were surveyed at baseline, 6 months, and 12 months; surveys assessed MHG involvement (5-item scale) and alcohol outcomes (i.e., abstinence, alcohol problems, heavy drinking). Generalized Estimating Equations (GEE) models tested effects for MHG involvement, demographics, and their interactions on outcomes at next survey.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In adjusted models, lagged MHG involvement consistently predicted better outcomes and showed significant interactions with both age (for alcohol problems and heavy drinking) and race/ethnicity (for alcohol problems). Follow-up analyses showed that MHG involvement was protective against alcohol problems for those aged 30–59 and 60+ (ORs = 0.35–0.37, <i>p</i>s < 0.05) but nonsignificant among those 18–29 (OR = 2.39, <i>p</i> = 0.10); similarly, MHG involvement was predictive of fewer drinking days for those 30–59 and 60+ (IRRs = 0.02–0.11, <i>p</i>s < 0.001) but nonsignificant among those 18–29 (IRR = 1.05, <i>p</i> = 0.90). Meanwhile, MHG involvement was protective against alcohol problems for Non-Hispanic White participants (OR = 0.34, <i>p</i> < 0.001) but nonsignificant among those of any other race/ethnicity (OR = 1.71, <i>p</i> = 0.20).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>MHG involvement may confer diminished benefits for young adults and people of color. These subgroups may benefit from tailored meetings and/or alternative activities that foster peer support for recovery.</p>\u0000 </section>\u0000 </div>","PeriodicalId":72145,"journal":{"name":"Alcohol (Hanover, York County, Pa.)","volume":"50 7","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148426729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
