This study identified classes of developmental trajectories of physical dating violence victimization from grades 8 to 12 and examined theoretically-based risk factors that distinguished among trajectory classes. Data were from a multi-wave longitudinal study spanning 8th through 12th grade (n = 2,566; 51.9 % female). Growth mixture models were…

Teen dating violence is a crime of national concern with approximately one-fourth of adolescents reporting victimization of physical, psychological, or sexual dating violence each year.

Considerable research has documented associations between adverse life events and internalizing symptoms in adolescents, but much of this research has focused on the number of events experienced, with less attention to the ecological context or timing of events. This study examined life events in three ecological domains relevant to adolescents…

The interplay between intrapersonal risk (low self-esteem, perfectionism and body dissatisfaction) and interpersonal protection (social support) appears relevant for delineating gender-specific pathways that lead to both depressive and eating psychopathology.

Ninety-four, low…

The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774 (52% female) adolescents. Participants (10-15 years of age at Time 1) completed self-report measures at three measurement occasions separated by 1 year each. Mean group difference results showed that both body satisfaction…

Given prevalence rates and negative consequences that adolescents' perpetration of dating violence may have on an individual's well-being and future relationships, it is imperative to explore factors that may increase or reduce its occurrence. Thus, we aimed to identify how multiple contextual risk factors (individual, family, schools, and…

Parental support and parental depressive feelings are found to be associated with depressive feelings in adolescent boys and girls, but results are inconsistent. In addition, the "5-HTTLPR" genotype has been found to interact with environmental stressors in predicting adolescents' depressive feelings, but this has not been examined longitudinally.…
