Relationship Dynamics and Young Adult Drug Use and Abuse

描述（由申请人提供）：拟议的研究将调查酒精和其他药物（AOD）使用的发育轨迹、社会适应和成年早期亲密伴侣调整之间的共同变化。纵向样本最初在 11 岁至 25 岁之间分 9 波进行评估。随访期间参与者的年龄为 25-30 岁。在早期成人随访中，参与者将被邀请参加生态评估，其中包括与关系伙伴的录像观察，随后进行 6 项简短的季度调查，收集 18 个月内有关活动生活方式、关系调整、关系变化和 AOD 使用的信息。此外，最初分配的实验组将在初次评估后接受关系检查或成人检查。分析将侧重于了解在从青春期早期到成年的问题行为的发展轨迹的背景下，相对于不断变化的关系和活动生活方式，成年早期 AOD 使用的稳定性和变化。将使用多变量模型来考虑青少年干预和青年干预在成人 AOD 使用、关系调整和活动生活方式方面的独特和综合影响。这项研究与有效的早期成人短期干预措施的设计直接相关，这些干预措施可促进健康的关系和家庭形成，并解决 AOD 在各种服务环境中的使用，例如高等教育、社会服务和军队。

DESCRIPTION (provided by applicant): The proposed study will investigate the co variation between alcohol and other drug (AOD) use developmental trajectories, social adaptation, and intimate partner adjustment in early adulthood. The longitudinal sample was originally assessed in 9 waves between ages 11 and 25 years. Participants will be age 25-30 years during the follow-up period. In the early adult follow-up, participants will be invited to participate in an ecological assessment that will include a videotaped observation with a relationship partner, followed by 6 brief, quarterly surveys that will capture information about activity lifestyle, relationship adjustment, changes in relationships, and AOD use over an 18-month period. In addition, the originally assigned experimental group will be offered the Relationship Check-Up or Adult Check-Up following the initial assessment session. Analyses will focus on understanding stability and change in AOD use in early adulthood relative to changing relationships and activity lifestyles, in the context of developmental trajectories of problem behavior from early adolescence through adulthood. Multivariate modeling will be used to consider the unique and combined influence of the adolescent intervention and the young adult intervention in terms of adult AOD use, relationship adjustment, and activity lifestyles. This research is directly related to the design of effective early adult brief interventions that promot healthy relationships and family formation and address AOD use in a variety of service contexts, such as postsecondary education, social services, and the military.
