Purpose Early adverse childhood experiences (ACEs) predict early onset of sexual intercourse. However, patterns of ACEs identified using latent class analysis (LCA) and their links to early sexual intercourse have been less examined. In this study, we apply LCA to identify ACEs profiles at age five and to examine whether these profiles differentially predict adolescents' sexual initiation. Methods

Purpose The COVID-19 pandemic highlighted the need for innovative approaches to delivering care. Self-collect, mail-in sexually transmitted infection (STI) testing could address barriers to in-person STI testing, particularly for youth, who bear a disproportionate burden of STIs. This study sought to obtain youth input on the development of a free self-collect, mail-in STI testing program. Methods

In their recent examination of the Monitoring the Future (MTF) data, McCabe et al. (Journal of Child Psychology and Psychiatry, 2023) address the complex, longstanding, and clinically valuable questions of whether and how stimulant medication treatment for adolescents with ADHD relates to their risk for substance use. Here, we expand on the authors' interpretations of their nuanced findings of increased

Purpose Cross-sectional studies have shown an association between lower help-seeking intentions and greater depressive symptoms among adolescents. However, no longitudinal study has examined the direction of this association. The current study investigated whether help-seeking intentions and depressive symptoms are reciprocally associated at the within-person (individual) level during early to mid-adolescence

Purpose Earlier pubertal timing is an important predictor of emotional and behavioral problems during adolescence. The current study undertook a comprehensive investigation of whether the social environment can buffer or amplify the associations between pubertal timing and emotional and behavioral problems.
