BACKGROUND Emerging adulthood (ages 18-26) is a time of identity exploration, experimentation, focusing on self or others, and instability, themes captured in the Inventory of Dimensions of Emerging Adulthood (IDEA). Preliminary evidence suggests that emerging adults (EAs) with a history of adverse childhood experiences (ACE) score differently on transition dimensions than their peers, however, the role of ACE in the IDEA-substance use relationship is unknown. METHOD Data are from a longitudinal study of acculturation and health among Hispanics in California (N = 1,065). Multivariable regression models assessed the association between IDEA and ACE (no ACE, 1-3 ACE, and ≥ 4 ACE) for substance use behaviors over 2 time points. Interaction terms assessed whether ACE moderated the association between subjective perceptions of IDEA at age 20 and substance use at age 24. RESULTS ACE-exposed EAs scored higher on identity exploration, instability, self-focus, and experimentation dimensions than their peers (ps < .01-.001). Scores on experimentation, identity exploration, and self-focus at age 20 were associated with divergent patterns of substance use across ACE exposure categories. In comparison to other groups, individuals in ≥ 4 ACE group who strongly identified with these transition themes at age 20 had the highest probability of binge drinking, past 30-day alcohol, marijuana, and illicit drug use at age 24 (adjusted odds ratios = 1.09-1.49, confidence interval [1.02-2.58]). CONCLUSION Our findings suggest that ACE can affect subjective perceptions of transition themes and increased risk for substance use over time. Implications for substance use prevention efforts tailored to Hispanic EAs are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

西班牙裔社区队列中新兴成人过渡主题、不良童年经历和物质使用模式之间的关系。

背景 新兴成年期（18-26 岁）是一个身份探索、实验、关注自我或他人以及不稳定的时期，这些主题被纳入新兴成年期维度清单 (IDEA)。初步证据表明，具有不良童年经历 (ACE) 历史的新兴成年人 (EA) 在过渡维度上的得分与同龄人不同，但是，ACE 在 IDEA 与物质使用关系中的作用尚不清楚。方法 数据来自加利福尼亚州（N = 1,065）西班牙裔文化适应和健康的纵向研究。多变量回归模型评估了 IDEA 和 ACE（无 ACE、1-3 次 ACE 和 ≥ 4 次 ACE）在 2 个时间点内的物质使用行为之间的关联。交互项评估 ACE 是否调节了 20 岁时对 IDEA 的主观感知与 24 岁时物质使用之间的关联。结果 ACE 暴露的 EA 在身份探索、不稳定性、自我关注和实验维度上的得分高于同龄人 (ps < . 01-.001）。20 岁时实验、身份探索和自我关注的分数与跨 ACE 暴露类别的不同物质使用模式相关。与其他组相比，≥ 4 ACE 组中在 20 岁时强烈认同这些过渡主题的个体在 24 岁时暴饮、过去 30 天饮酒、吸食大麻和使用非法药物的可能性最高（调整后的优势比 = 1.09-1.49，置信区间 [1.02-2.58]）。结论 我们的研究结果表明，随着时间的推移，ACE 会影响对过渡主题的主观看法和增加的物质使用风险。讨论了针对西班牙裔 EA 的物质使用预防工作的影响。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
