"I'm an adult now": Health risk behaviors and identifying as an adult.

Is identifying as an adult associated with lower rates of participation in risky behaviors? This study focuses on how identity affects health behaviors for young adults. We use an original sample of over 500 18- to 29-year-olds in the United States to explore how self-identification as an adult is associated with three clusters of health risk behaviors: substance use, risky sexual behavior, and risky driving behavior. Consistent with our predictions, we find that viewing oneself as an adult is associated with lower levels of participation in each of the health risk behavior outcomes.

Sexual Revictimization: A Routine Activity Theory Explanation.

Research has shown that victims of sexual assault are at a significant risk of revictimization. We use routine activity theory to predict how sexual victimization in adolescence relates to depression, substance use, and ultimately revictimization as a young adult. We frame our research within routine activity theory and predict that sexual victimization increases substance use and depressive symptoms, both of which increase the likelihood of revictimization. We test the hypotheses with three waves of data from the Longitudinal Study of Violence Against Women. Using structural equation modeling, we examine the direct and indirect effects of previous sexual victimization, depressive symptoms, and substance use on the odds of victimization during the sophomore year of college. Results suggest that sexual victimization during the sophomore year of college is predicted directly by previous sexual victimization and also indirectly through depressive symptomology, though not substance use. Although understudied in the literature, depression is shown to mediate the relationship between victimization and revictimization, and this finding is consistent with routine activity theory, as well as the state dependence perspective on revictimization. Our findings suggest that depressive symptoms, a long acknowledged consequence of sexual victimization, should also be understood as a source of revictimization risk, indicating the importance of depression screening and intervention for decreasing sexual victimization.

Romantic relationships and health among African American young adults: linking patterns of relationship quality over time to changes in physical and mental health.

With trends in delayed marriage, scholars have begun to explore how a wide range of romantic relationships contribute to health. Although a welcome shift, this largely cross-sectional work ignores potential (in)stability in relationship supports and stressors thought to affect health. Using Family and Community Health Study data on 634 African American young adults, we extend this work by demonstrating the value of a holistic, multidimensional assessment of relationship quality for understanding the link between relationships and health. In addition, however, we also show that there is substantial instability in both the presence and quality of romantic relationships during the transition to adulthood. Importantly, particular patterns of instability are uniquely associated with changes in mental and physical health. Given persistent racial inequalities across both relationships and health, such findings prove theoretically and practically important. In particular, they highlight the need for more contextualized, life course-sensitive approaches in future work.
