OBJECTIVE Little is known about the clinical presentation and course of oppositional defiant disorder (ODD) when first diagnosed in the preschool years. Patterns of ODD symptomatology, comorbidity, persistence of disorder, and predictors of diagnostic outcome were examined in clinic-referred preschool boys. METHOD Boys (aged 4-5.5 years) with a DSM-III-R(More)
School-age children and adolescents with conduct problems typically exhibit deficits in verbal IQ, language abilities, and executive functions. This study examined the extent to which this pattern was evident in a clinic group of preschool boys with early onset conduct problems who met criteria for oppositional defiant disorder (ODD) with and without(More)
Twenty-three mothers and their 5- to 7-year-old children with craniofacial anomalies (CFA) who were assessed during the child's infancy were followed. Three types of CFA were included: cleft lip and palate (CLP), isolated cleft palate (CP), and sagittal synostosis. Measures of child status focused on behavior-problem frequency and self-concept. Mothers(More)
The current study utilized both variable- and person-oriented analyses to examine correlates of early disruptive behavior problems. Participants included 80 preschool boys referred to a child psychiatry clinic and diagnosed with oppositional defiant disorder (with or without attention-deficit hyperactivity disorder) and 80 case-matched normal comparison(More)
There is a need for practical and cost-effective measures of the behavioral characteristics that predict subsequent injury in children. Previous research has focused on the predictive power of child problem behavior (e.g., hyperactivity, aggression, noncompliance) and has found reliable, but relatively weak associations with injury frequency. In an effort(More)
Research literature linking negative and positive aspects of the father-child relationship with early onset conduct problems is reviewed. Evidence from the Preschool Families Project, a longitudinal study of clinic-referred preschool boys at risk for conduct disorder, is presented, including previously unpublished data on father-child attachment. Both(More)
OBJECTIVE We assessed the neurodevelopment of infants with and without deformational plagiocephaly (DP), at an average age of 6 months. METHODS The Bayley Scales of Infant Development III (BSID-III) were administered to 235 case subjects and 237 demographically similar, control participants. Three-dimensional head photographs were randomized and rated for(More)
Little is known about genes that underlie isolated single-suture craniosynostosis. In this study, we hypothesize that rare copy number variants (CNV) in patients with isolated single-suture craniosynostosis contain genes important for cranial development. Using whole genome array comparative genomic hybridization (CGH), we evaluated DNA from 186 individuals(More)
OBJECTIVE To evaluate the cognitive and language development of untreated infants with a single suture craniosynostosis at time of diagnosis. DESIGN AND PARTICIPANTS The study presents time 1 assessments on the first 100 infants with a single suture craniosynostosis (sagittal, metopic, unilateral coronal, and lambdoid) referred to the Infant Learning(More)
OBJECTIVE To review research and theory regarding the neurobehavioral correlates and outcomes of single-suture, or isolated, craniosynostosis in children. METHODS A critical review of 17 studies of the hypothesized association between isolated craniosynostosis and neurodevelopment. RESULTS Isolated craniosynostosis is associated with a three- to(More)
