A typology of behavior problems in preschool children.

The purpose of this study was to produce a typology of behavior problems in preschool children. Distinct subtypes were identified through the use of cluster analytic techniques on data from the Behavior Assessment System for Children (BASC)-Parent Rating Scales. Analyses were based on archival data collected on a sample of 268 children, aged 2 to 5 years, who were referred to determine their suitability for a day treatment program. Five distinct and reliable subtypes of preschool children's behavior problems emerged. Ratings of adaptive and social skills based on the BASC Adaptive Scales and measures from the Parenting Stress Index served as external variables to assess the distinctiveness of the derived subtypes. The findings provide evidence for the reliability and validity of the subtypes identified in this study that are consistent with the findings of previous subtyping investigations focusing on school-aged children.

Neuropsychological characteristics of juvenile delinquency.

Knowledge of the neuropsychological characteristics related to JD and other behavioral disturbances in childhood is an important aspect of pediatric care. Referral of patients with developing behavioral problems for neuropsychological evaluation may assist pediatricians with identifying neuropsychological risk factors for JD, clarifying differential diagnostic questions, providing information for the nature of intervention efforts, and providing useful predictive tools for long-term planning and outcome. Thus, referrals for neuropsychological evaluation should not occur solely within the context of a patient with known central nervous system compromise. Neuropsychological results may be of benefit with disorders wherein the precise brain-behavior relationship is unclear, such as with JD. Once a child's neuropsychological characteristics are known and evaluated from a behavioral risk standpoint, pediatricians will have information that is pivotal to asserting recommendations for modifications to the home and school environments, as well as for direct intervention and treatment. The direction of future neuropsychological research includes the early identification of children and adolescents with potential behavioral disturbance. Accurate early differential diagnosis and knowledge of neuropsychological risk factors help to achieve this goal. Neuropsychological research and knowledge assist with understanding the complexities of interactions between environmental vulnerabilities and neuropsychological risk factors, and can provide useful predictive and preventative information for pediatricians.
