Risky Interactions: Relational and Developmental Moderators of Substance Use and Dating Aggression

Physical dating aggression is a prevalent and costly public health concern. A theoretical moderator model of substance use and dating aggression posits that associations between them are moderated by relational risk factors. To test these theoretical expectations, the current study examined seven waves of longitudinal data on a community-based sample of 100 male and 100 female participants in a Western U.S. city (M age Wave 1?=?15.83; 69.5% White non-Hispanic, 12.5% Hispanic, 11.5% African Americans, & 12.5% Hispanics). Multilevel models examined how links between substance use and dating aggression varied by relational risk and how these patterns changed developmentally. Main effects of relational risk and substance use emerged, particularly in adolescence. In young adulthood significant three-way interactions emerged such that substance use was more strongly associated with physical aggression when conflict and jealousy were higher. Thus, relational risk factors are integral to models of dating aggression, but their role changes developmentally.

     

Associations between Dating Aggression Involvement and Subsequent Relationship Commitment

Little is known about how an individual’s commitment to their romantic partner evolves over the course of a relationship following involvement in dating aggression (DA). The present study explored longitudinal associations between both psychological and physical DA involvement and subsequent changes in commitment. We hypothesized that experiences of physical and psychological DA may be related to decreased feelings of commitment (including both dedication and constraint) in a relationship, and that gender may moderate the link between DA and changes in commitment. One-hundred and twenty (60 female) young adults (ages 18–25) in a romantic relationship completed electronic questionnaires each month for 6 months, (M age Wave 1?=?22.44, SD =?2.20). DA involvement and commitment were measured by the Revised Conflict Tactics Scale, and the Revised Commitment Inventory, respectively. Using multilevel modeling, the current study examined shifts in commitment (dedication and constraint) following DA involvement. As hypothesized, physical and psychological dating aggression involvement were both associated with declines in relationship commitment. Analyses also tested for potential gender interactions with physical and psychological dating aggression involvement for both constraint and dedication. No significant gender interactions emerged. These findings add to the accumulating evidence for the deleterious effects of dating aggression on relationships, including on relationship commitment, and illustrate important implications for interventions aimed at reducing dating aggression among young adults.
