Guided by the goal of documenting the natural course of the life histories of a large sample of hyperactive children and their control counterparts, this research reports the extent to which prenatal, developmental, and health history factors distinguish hyperactive and control groups, as well as the relative contributions of the various medical factors.(More)
This study reconsiders the relationship of childhood Attention Deficit/Hyperactivity Disorder (ADHD) and childhood conduct problems with adult criminal activity by clarifying the role of the cardinal behaviors associated with the DSM-IV ADHD subtypes (inattention and hyperactivity/impulsivity). Since their childhood (average age 9 years), 230 male and 75(More)
Hyperactive boys and matched controls from a large-scale epidemiological study, followed for at least three years to age 12, were compared on parent and teacher reports and assessments of attention, achievement, and intellectual functioning. Three outcome groups, based on presence or absence of hyperactivity symptoms, were derived and compared to the(More)
The pattern and progression in drug use across a 1-year interval was investigated for 54 hyperactives and 47 controls aged 13-18. Initiation and use rates between groups at Time 1 and Time 2 also were studied. Patterns of drug usage differed slightly between hyperactives and controls, with the hyperactives showing greater involvement with cigarettes. As(More)
This paper reports direct experience with two commercial, widely used visual programming environments. While neither of these systems is object oriented, the tools have transformed the development process and indicate a direction for visual object oriented tools to proceed. This paper reports on real world applications of visual tools that have exposed a(More)
Much time is spent in elementary schools in assessment of cognitive attributes of children, little in measurement of noncognitive attributes. This study evaluates relative importance of early assessments of cognitive versus noncognitive variables as predictors of high school achievement and adjustment. Results demonstrate the critical, and frequently more(More)
Hyperactivity is a complex childhood problem and may represent several groups or syndromes, each with its own etiological patterns. This paper presents results of analyses indicating that, although biological and demographic factors may predispose children to being identified and treated as hyperactive, the major contributions to the condition are early(More)
Student teachers in yearlong mental health consultation groups completed Moos's Group Environment Scale (GES) and three semantic differential ratings of their satisfaction with the group experience. Factor analysis of the GES yielded four dimensions, the first two corresponding to Moos's hypothesized dimensions of Relationship and System Maintenance/System(More)
A factor analysis of the "Behavior and Temperament Survey--Home Version" resulted in four independent dimensions that were consistent with the DSM-III diagnostic criteria for inattention, hyperactivity, and conduct disorders. A factor dimension labeled "Impulsivity," not in DSM-III also resulted. Data include correlations between scales, descriptive(More)
Strategies are discussed for locating and interviewing a community-based sample of 492 adults, approximately half of whom were diagnosed in 1974 with ADHD. Completion rates, reasons for attrition, and amount of time and intensity of effort associated with subject location are reported. We found that 81% of the original sample had been located after 28(More)
