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

 描述(由申请人提供)：这份修订的R01申请寻求前瞻性地研究青年时期(青年早期、中期和晚期)三个过渡期酒精使用变化的预测因素。流行病学数据表明，酒精使用和酒精紊乱的高峰期发生在18-25岁之间，在这一年龄段之后使用减少。成熟，即个人承担成人角色(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。评估戒酒成熟度的研究数量有限，结果喜忧参半，一些研究支持总体减少饮酒，而另一些研究则表明存在很大的异质性。这个R01应用程序建议使用一个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酒精使用变化的预测因素。来自年轻人、他们的配偶和他们的父母的多源数据将被用来调查人际因素(例如冲突、支持)和年轻人在婚姻和家庭背景下饮酒的作用。与工作和人际关系有关的压力因素也将作为酒精使用变化的联合预测因素进行调查。将使用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、潜在转变模型)来评估跨YA转变的酒精使用的变化。

 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.
