Relationship Dynamics and Young Adult Drug Use and Abuse

描述（由申请人提供）：本研究将探讨成年早期酒精和其他药物（AOD）使用发展轨迹、社会适应和亲密伴侣适应之间的共变异。纵向样本最初是在11至25岁之间的9波中进行评估的。在随访期间，参与者的年龄为25-30岁。在成年早期随访中，参与者将被邀请参加一项生态评估，其中包括与伴侣的录像观察，随后是6个简短的季度调查，这些调查将收集有关18个月期间的活动、生活方式、关系调整、关系变化和AOD使用情况的信息。此外，最初分配的实验组将在初始评估会议后提供关系检查或成人检查。分析将侧重于理解在青春期早期到成年期问题行为发展轨迹的背景下，相对于关系和活动生活方式的变化，成年早期AOD使用的稳定性和变化。多变量模型将用于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。这项研究直接关系到有效的早期成人简短干预的设计，这些干预可以促进健康的关系和家庭的形成，并在各种服务环境中解决AOD的使用问题，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.
