IntroductionSexting has emerged as a significant public health issue. Sexting is associated with substance use and other sexual behaviors, such as oral and vaginal sex (Houck et al., 2014; Temple & Choi, 2014). Current studies on sexting are often cross-sectional, limiting the ability to determine the temporal order of sexting and sexual behaviors. Additionally, studies focus on samples of young adults (Benotsch et al., 2013). The current study extends the literature by examining sexting and sexual behaviors longitudinally among adolescents and examines race and gender differences that play a role in sexting. MethodsThe current study utilizes a prospective, 4-year longitudinal study of 1240 adolescents (aged 11–17) living in the Midwestern United States. Overall, the sample was 10% Black males, 11% Black females, 34% White Males, 31% White females, and 15% identified as Other. Analysis includes an autoregressive model with cross-lagged effects in MPlus. ResultsSexting (T1) predicted oral and sexual encounters (T4) for Black males, White males, and White females but not for Black females. Oral sex and sexual encounters (T4) did not predict any sexting (T1) for all groups. Therefore, analysis establishes sexting as an antecedent to sexual behaviors for Black males, White males, and White females. Sexting and sexual behaviors did not have a significant association for Black females. ConclusionsThis study identifies sexting as a precursor to sexual behaviors among adolescents. Therefore, when tailoring programs for safe sex among these populations, focusing on sexting may reduce other sexual risky behaviors.
