Researchers have recognized the importance of developing an accurate classification system for externalizing disorders, though much of this work has been framed by a priori preferences for categorical vs. dimensional constructs. Newer statistical technologies now allow categorical and dimensional models of psychopathology to be compared…

The atypical antipsychotic medication aripiprazole was evaluated using a randomized AB multiple baseline, double-blind, placebo-controlled design for the treatment of severe problem behavior with 4 children with intellectual and developmental disabilities. Functional analysis (FA) was conducted concurrent with the medication evaluation to…

Background: A functional polymorphism in the promoter region of the monoamine oxidizing gene "monoamine oxidase A" ("MAOA") has been associated with behavioral sensitivity to adverse environmental conditions in multiple studies (e.g., Caspi et al. 2002; Kim-Cohen et al., 2006). The present study investigates the effects of…

This study examined the consistency between the findings of developmental coordination disorder (DCD) as identified by the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) and the Movement Assessment Battery for Children (MABC), and explored the psychosocial and attention characteristics of children with DCD identified by the two motor tests,…

The Tourette's Disorder Scales (Shytle et al., 2003) are parent- (Tourette's Disorder Scales-Parent Rated; TODS-PR) and clinician-rated (Tourette's Disorder Scales-Clinician Rated; TODS-CR) measures that assess tics, obsessions, compulsions, inattention, hyperactivity, aggression, and emotional disturbances among children with tics. Although the…

Examines the convergence of 6 measures of aggression in a group of 43 children and adolescents with disruptive behavior disorders. The results suggest that measurement of clinically salient physical aggression requires multiple informant sources and that the Child Behavior Checklist and Iowa Conners Aggression Factor are assessing dimensions other…

A study involving 1,097 2-year-olds examined whether the items located on the Child Behavior Checklist/1-5 would provide reasonable indicators of the seven first-order behavioral dimensions purportedly measured by this instrument. Results support the presence of six factors: somatic complaints, withdrawn, attention problems, aggressive behaviors,…

Standardized rating scales are the most often used part of the multidimensional assessment of children's behavior. However, low cross-informant correlations raise concerns about the reliability and validity of the resulting scores. This study examined whether the manner in which behavioral constructs are measured differs across informants, across…
