Dr. Lefkowitz's research takes a developmental perspective on sexual behaviors and attitudes during adolescence and the transition to adulthood. She has addressed two major areas of research: (1) predictors of negative and positive aspects of sexual health; and (2) broader health and relationship implications of sexual health. Across her research projects, she includes individuals from diverse ethnic and racial backgrounds, and ask research questions about how fundamental processes may differ by factors such as gender or race/ethnicity. She has been a principal investigator, co-investigator, or faculty mentor on projects funded by the NICHD, NIAAA, NIA, NIDA, and the WT Grant Foundation. Current projects include the University Life Study, a measurement burst design study in which researchers followed college students across seven semesters to examine their sexual behavior, alcohol use, and other health behaviors, and the PROSPER Peers study, in which researchers are using social network data to better understand how peers and romantic partners influence sexual behaviors. Dr. Lefkowitz is also interested in developing research on sexual violence on college campuses.

Long-distance dating relationships (LDDRs) and the dissolution of these relationships may have implications for day-to-day affect and behaviors. The current study examined the associations of relationship status, long-distance relationship dissolution, and daily location with daily positive affect, loneliness, university activity engagement, and alcohol use. College students (n = 718, 51.5% female, 43.9% ...
Casual sexual relationships and experiences (CSREs) are common among emerging adults, and their diversity may contribute to variability in their associations with mental health and future romantic relationship development. The present research used multiple regression analyses to examine how CSRE type (casual dating, friends with benefits [FWB], or booty call/one-night stand) is associated ...
The present research examined how the within-person association between sexual initiation and internalizing symptoms decays over time, using data with annual measurement occasions across adolescence (N = 1,789) and statistical models of within-person change. Sexual initiation was associated with increased levels of internalizing symptoms for early-initiating girls (ninth grade, approximately age ...
Diverse patterns of sexual behaviors contribute to development and well-being. A person-oriented approach to studying sexual behaviors provides a nuanced understanding of sexual repertoires. The goals of this paper were to document patterns of sexual behaviors ranging from kissing to penetrative sex, and to examine how latent classes of behaviors, gender, and partner type (romantic ...
Although parenting is clearly linked to academic engagement in adolescence, less is known about links between parenting and academic engagement in emerging adulthood. A diverse sample of college students (N = 633; 53.1% female, 45.7% White/European American, 28.3% Asian American/Hawaiian/Pacific Islander, 26.4% Hispanic/Latino American, 21.6% Black/African American, and 2.8% Native ...
