A functional polymorphism in the promoter of the gene encoding monoamine oxidase A has been associated with problem behavior in various populations. We examined the association of MAOA alleles in adult males with intellectual/developmental disabilities with and without established histories of problem behavior. These data were compared with a…

Attention-deficit/hyperactivity disorder (ADHD) is a common example of developmental psychopathology that might be able to be better understood by taking an emotion regulation perspective. As discussed herein, emotion regulation is understood to consist of two component processes, emotion (e.g., positive and negative emotionality) and regulation…

Although females represent almost half of all youth involved in residential care in the US, very little is known about this population. In order to examine differences in characteristics of male (n = 308) and female (n = 180) youth departing from residential care, data were collected on 488 youth from a large residential treatment facility in the…

The goal of this study was to explore the socioemotional adjustment of unsociable (versus shy) children in middle childhood. The participants in this study were 186 children aged 6-8 years (M[subscript age] = 7.59 years, SD = 0.31). Multisource assessment was employed, including maternal ratings, teacher ratings, and individual child interviews.…

This study utilized growth mixture modeling to examine the impact of parents, child care providers, teachers, and peers on the prediction of distinct developmental patterns of classroom externalizing behavior in elementary school. Among 241 children, three groups were identified. 84.6% of children exhibited consistently low externalizing behavior.…

This cross-sectional study examined the nature of child and adolescent psychopathy using the Antisocial Process Screening Device (APSD) in 3,675 schoolchildren (ages 11-16) in Hong Kong, China. A confirmatory factor analysis observed a good fit for the three-factor model (callous-unemotional, impulsivity, narcissism) of APSD, with boys scoring…

We examined the associations and likely pathways underlying the relationships between peer attachment style, self-concept, and Internalizing/Externalizing Problems among high school students in Japan. A total of 228 senior high school students (186 boys and 82 girls; mean age = 16.4) completed the Attachment Questionnaire for Children,…

Peer nominations and demographic information were collected from a diverse sample of 1493 elementary school participants to examine behavior (overt and relational aggression, impulsivity, and prosociality), context (peer status), and demographic characteristics (race and gender) as predictors of teacher and administrator decisions about…

We investigated the relationship between challenging behavior and co-morbid psychopathology in adults with intellectual disability (ID) and autism spectrum disorders (ASDs) (N=124) as compared to adults with ID only (N=562). All participants were first time referrals to specialist mental health services and were living in community settings.…

The purpose of this quantitative, causal comparative study was to examine the extent to which attending an alternative educational program at some point during high school could likely influence the graduation rate of at-risk students in an urban school district in the state of Missouri. Four years of nonrandom samples of graduation data from 2006…

The current study evaluated risk factors for the occurrence, frequency and severity of challenging behavior among a sample of individuals with a diagnosis of autism, under the age of eighteen, in Ireland. Age, gender, hours of intervention received, age at diagnosis, presence of challenging behavior at diagnosis and treatment type at diagnosis…

This study examines the predictive significance of late adolescent substance use groups (i.e., abstainers, experimental users, at-risk users, and abusers) for early adult adaptation. Participants (N = 159) were drawn from a prospective longitudinal study of first-born children of low-income mothers. At 17.5 years of age, participants were assigned…

Teachers rated 191 first-grade immigrant students attending Islamic and public schools in the Northeast United States. The results showed that when teachers perceived parents…

This study examined sons' and daughters' involvement with nonresident fathers and associated outcomes (N = 4,663). Results indicated that sons and daughters reported equal involvement with nonresident fathers on most measures of father investment, although sons reported more overnight visits, sports, and movies and feeling closer to their fathers…

The aim of this study was to identify risk factors for the occurrence of challenging behavior along with the specific topographies of challenging behavior shown by a sample of children with autism spectrum disorder in Ireland. The occurrence of challenging behavior was examined in comparison with the following variables: gender, age, level of…
