1. Adolescent romantic relationships and substance abuse: The benefits of thinking it will last forever J. Claire Stephenson, David E. Szwedo, Joseph P. Allen The University of Virginia Introduction  On the one hand, involvement in romantic relationships can expose an adolescent to damaging experiences such as physical and relational aggression, as well as difficulties associated with relationship dissolution.  Engagement in romantic relationships has been linked to adolescent depression, suicide, and risky sexual behavior.  On the other hand, a romantic partner can be a vital source of companionship, support and intimacy for an adolescent.  It can be expected that adolescent involvement in romantic relationships will also be associated with positive outcomes.  The purpose of the current study is to investigate how involvement in romantic relationships during adolescence impacts future substance use.  Based on findings that indicate that married adults have fewer substance abuse problems, we hypothesized that adolescents who engage in a romantic relationship that carries characteristics typical of a marriage (in terms of commitment and expected duration) will have greater decreases in alcohol-related problems and hard drug use over time relative to those in less committed relationships.  Network of Relationships Inventory (Furman & Buhrmester, 1985)  Reliable Alliance scale  assessed the extent to which the adolescent believed his or her relationship would last no matter what  completed by participants at Time 2 (mean age=18.30)  Participants reported how many alcohol-related problems they had experienced in the past year at Time 1 (mean age=17.32) and Time 3 (mean age=20.76)  Examples of problems  missing class or work  driving under the influence  being taken advantage of sexually  getting hurt or injured  Participants reported the number of times they had used hard drugs in the past year at Time 1 and Time 3  Time 1 measures, as well as gender and income, will be used as covariates in all analyses Participants Discussion Results  Participants were part of a larger, ongoing longitudinal study of adolescent development  Chosen for this study based on the fact that they were in a romantic relationship of at least three months at Time 2 (mean age=18.30)  Target adolescent demographics  56 females and 41 males (total N= 97)  Ethnically and Socio-economically diverse Table 1.

It is possible that a third variable, such as maturity, could account for the relationship between romantic relationship involvement and decreased substance abuse  Areas of future research include further exploring other benefits of committed adolescent romantic relationships and examining other possible predictors of decreases in substance abuse Table 2.
