Maturing Out: Childhood and Adolescent Predictors of Transitions in Alcohol Use in Young

 描述（由申请人提供）：此修订后的R 01申请旨在前瞻性地研究青年期三个过渡期（早期，中期和晚期）酒精使用变化的预测因素。流行病学数据表明，酒精使用和酒精障碍的高峰期发生在18-25岁之间，在此年龄段之后使用减少。成熟，即，当个体承担成人角色时（例如，婚姻伴侣，全职员工），已被提出作为这些行为变化的解释。有限数量的研究评估成熟的酒精使用产生了混合的结果，一些支持使用的整体减少，而其他研究表明实质性的异质性。该R 01应用程序建议使用23年的七波纵向数据集，年龄范围为15-34岁，以检查青少年和年轻人在青年期饮酒变化的预测因素。来自年轻人、他们的配偶和他们的父母的多项数据将用于调查人际因素的作用（例如，冲突，支持）和年轻的成年人在婚姻和家庭环境中使用酒精。与工作有关的和人际关系的压力源也将作为饮酒变化的联合预测因素进行调查。几种不同的分析技术（例如，潜在增长模型、潜在增长混合模型、潜在过渡模型）将用于评估跨YA过渡的酒精使用变化。

 DESCRIPTION (provided by applicant): This revised R01 application seeks to prospectively study predictors of changes in alcohol use across three transitional periods in young adulthood (early-, middle-, and later-young adulthood). Epidemiologic data indicate that the peak period for alcohol use and alcohol disorders occurs between ages 18-25 years, with reductions in use following this age interval. Maturing out, i.e., as individuals assume adult roles (e.g., marital partner, full-time employee), has been proposed as an explanation for these behavioral changes. The limited number of studies evaluating maturing out of alcohol use have yielded mixed findings, with some supporting overall reductions in use whereas other studies suggest substantial heterogeneity. This R01 application proposes to use a 23-year, seven-wave longitudinal dataset, with an age range of 15-34 years to examine adolescent and young adult predictors of changes in alcohol use across young adulthood. Multisource data from young adults, their spouses, and their parents will be used to investigate the role of interpersonal factors (e.g., conflict, support) and young adult alcohol use in the marital and family context. Work-related and interpersonal stressors will also be investigated as joint predictors of changes in alcohol use. Several different analytic techniques (e.g., latent growth models, latent growth mixture models, latent transition models) will be used to evaluate changes in alcohol use across YA transitions.
