Children identified as Attention Deficit Disorder (ADD) on the basis of teacher ratings using the SNAP Rating Scale were compared to non-ADD children on objective classroom measures including observations of classroom behavior, examination of the organization of children's desks, and scoring of daily academic work. Analyses provided some support for the ability of the objective measures to differentiate between teacher-identified ADD and non-ADD children, though there was considerable overlap on the distributions of most variables between groups. Six measures chosen by a discriminant analysis combined to predict teacher ratings in 83% of the cases. The inclusion of academic, observational, and desk measures in the discriminant function indicates the importance of a multivariate assessment of this construct.

Results suggested that in this family of Standard Poodles, PIE was inherited as a simple recessive autosomal trait with complete or almost complete penetrance. Seizures often had focal, as opposed to generalized, onsets, and it was not uncommon for seizures to begin after 5 years of age.

The ability of school-based measures of child behavior to predict differentially the IOWA Conners teacher rating scale Inattention/Overactivity (IO) and Aggression (A) factors was evaluated in a sample of 71 school-aged boys. Multiple measures and multiple methods of assessment were utilized to provide a comprehensive assessment of social and academic behavior. These included direct observations of children in the classroom and on the playground, examination of the organization of children's desks, measures of academic performance, peer nominations of popularity and rejection, and sociometric ratings using the Pupil Evaluation Inventory. Despite moderately high correlations between the teacher rating factors (r = .60), considerable evidence was provided for differential validity on measures of academic performance, peer rating measures, and measures of disruptive or inappropriate classroom and playground behavior. These differences between IO and A factors indicated that the factors were logically independent in important ways, supporting prior work validating separate hyperactivity and aggression dimensions.

Seventy-four people with Parkinson's disease (PD) completed questionnaires and were interviewed to determine the degree to which the severity of PD and perceptions of primary and secondary control over PD predicted psychosocial adjustment. Significant unique contributions to PD-related participation restrictions were made by disease severity (positive relationship) and perceived internal secondary control (negative relationship). Also, participation restrictions had a significant direct effect, and disease severity and perceived internal secondary control significant indirect effects, on both depressive symptomatology and life satisfaction. Results are consistent with theories that suggest the importance of enhancing internal secondary control processes in situations in which actual control over objective circumstances is limited, such as with chronic and progressive diseases like PD.
