Transactional theories of development suggest that displaying high levels of antisocial behavior early in life and persistently over time causes disruption in multiple life domains, which in turn places individuals at risk for negative life outcomes. We used longitudinal data from 1,137 primarily African American urban youth (49.1% female) to…

Later-born siblings of children with autism spectrum disorder (Sibs-ASD) are at elevated risk for social impairments. Two putative predictors of later social impairment--measures of responding to joint attention and weighted triadic communication--were examined in a sample of 43 Sibs-ASD who were followed from 15 to 34 months of age. Results…

Challenging behaviors were assessed in 313 children, and it was demonstrated that children with autism spectrum disorders (ASD) exhibited greater levels of challenging behavior than both normally developing controls and children with psychopathology or atypical development. Next, we examined the relation between challenging behaviors and symptoms…

Two aspects of young children's cognitive representations of peer relationships-peer affiliative motivation and feelings and beliefs about the self and peers-were assessed among a sample of 75 children (37 girls), who ranged in age from 32 to 76 months (M = 58.2 months). Measures of three aspects of discrete social cognition, encoding of social…

The current study characterized stability and changes of autism diagnostic classification with intervention in very young children and examined pre-treatment predictors and post-intervention outcome. Sixty-eight children diagnosed with autism, aged 18-35 months (M = 25.4, SD = 4.0) participated in the study. Children underwent comprehensive…

The present study utilized a mixed retrospective and prospective design with an 8-month follow-up period to test a model of revictimization that included multiple childhood (i.e., child sexual, physical, and emotional abuse) and situational variables (i.e., substance use, sexual behavior) for predicting rape among 276 college women. It was of…

The purpose of the study was to advance our understanding of the developmental precursors of Moral Disengagement (MD) and the role of MD in the development of antisocial behavior from early risk among an ethnically diverse sample of 187 low-income boys followed prospectively from ages 1.5 to 17. Results indicated associations between early…

Potential pathways from childhood sexual abuse (CSA) to subsequent romantic intimacy problems were examined in a prospective longitudinal study of 160 ethnically diverse youth with confirmed CSA histories. Participants were interviewed at the time of abuse discovery, when they were 8-15 years of age, and again 1-6 years later. Stigmatization…

This study assessed the role of grandiosity and justification of violence cognitive schemas as predictors of adolescents' antisocial behavior. The 974 Spanish adolescents (457 girls and 517 boys, aged between 14 and 18 years) were assessed at the beginning of the school year and at follow-up 6 months later. They completed measures of aggressive…

A multi-informant and multi-measure short-term longitudinal study of the association between subtypes of aggression and peer victimization was conducted in an early childhood sample (M = 44.36 months; SD = 11.07; N = 120). Observational and teacher report measures demonstrated appropriate reliability and validity as well as stability across an…

Using holistic-interactionistic theory, the simultaneous nature of risk and protection factors for both males and females (age 6-11 in Wave 1) is examined using latent profile analysis (LPA). Risk/protection classes are estimated using multiple risk factor variables (e.g., physical child abuse) and multiple protective factors (e.g.,…

This research examined the potential relationship between adolescent problem behaviors and amount of time spent with violent electronic games. Survey data were collected from 1,254 7th and 8th grade students in two states. A "dose" of exposure to Mature-rated games was calculated using Entertainment Software Rating Board ratings of…

Inattentive-hyperactive and oppositional behavior have been hypothesized to be developmental precursors to conduct problems. We tested these hypotheses using a longitudinal sample of 6,466 offspring of women selected from nationally representative US households. Conduct problems across 8-13 years were robustly predicted by conduct problems at 4-7…

Studies identifying the mechanisms underlying the causes and consequences of antisocial behavior among female delinquents as they transit to adulthood are scarce and have important limitations: Most are based on official statistics, they typically are restricted to normative samples, and rarely do they gather prospective data from samples of…

Students (N = 221) in an intermediate school (grades 5-8) in a rural area of the Southwestern United States completed a survey regarding their familiarity with technology and their experiences with cyberbullying during the school year. Initial evidence of survey reliability is presented. In the sample, 1.5% of participants were classified as…
