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)
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)
The social-cognitive characteristics of 88 preschool boys with Oppositional Defiant Disorder (ODD) and 80 nondisruptive boys were assessed 3 times over a 2-year period. Three questions were addressed: (1) Do social-cognitive processes (encoding, attribution, problem solving, and response evaluation) distinguish clinic-referred preschool boys from peers(More)
We compared three methods of stimulus preference assessment for verbal children and specifically evaluated the utility of a verbal choice procedure for assessing relative reinforcer value. Using a token system, relative preference for five categories of reinforcers, representing 15 different stimuli, was assessed by three methods: a reinforcer survey, a(More)
We evaluated the relative treatment utility of a verbal forced-choice questionnaire, child nomination, and direct observation for identifying the most potent reinforcers for children with attention deficit hyperactivity disorder. Results demonstrated that all three methods were more likely to disagree than to agree, that a forced-choice format may enhance(More)
To assess the drug-behavior interaction effects with an 8-year-old boy wih attention deficit hyperactivity disorder, common classroom antecedent (e.g., seating arrangement) and consequent (e.g., peer prompts) stimuli were alternated within a school day while drug conditions (methylphenidate vs. placebo) were alternated across days. The results suggested(More)
We conducted functional analyses of classroom disruption during contingent teacher and peer attention conditions for 3 children with attention deficit hyperactivity disorder. Attention provided by peer confederates appeared to function as a distinct form of positive reinforcement for all 3 children.
We explored whether teacher feedback modified children's preferences and perceptions of a target child with behavior problems. First- and second-grade children (M age = 7.8 years) viewed a videotape of a target actor presented as having a liked, average, or disliked reputation. A second videotape depicted a teacher's verbal responses to the target's(More)
OBJECTIVE To compare at ages 3, 12, and 24 months the cognitive and psychomotor development of 29 infants with cleft lip and palate (CLP), 28 infants with cleft palate only (CPO), and a demographically matched comparison (COMP) group of 69 infants; to examine predictors of cognitive status at age 24 months in the cleft group. METHODS Infants were(More)
OBJECTIVE The validity of the Cognitive Performance Scale (CPS) embedded in the Resident Assessment Instrument-Mental Health (RAI-MH) was evaluated among adult psychiatric inpatients. METHODS The CPS is a brief measure of cognitive performance, with scores ranging from 0 (intact) to 6 (very severe impairment). The CPS scores were compared with the(More)
