    ABSTRACT: Children evaluated by an interdisciplinary team that provided data on psychiatric disturbance, language handicaps, and psychoeducational assessment were placed in special education classes following the complete evaluation. Discriminant analysis as a special case of multiple regression analysis determined that mean reading achievement score, pre-evaluation classroom placement, and to a lesser degree, Performance IQ predicted classroom placement. Overall, correct classroom predictions approached 90 percent. These findings highlight the value of interdisciplinary evaluation to educators and mental health professionals.

    ABSTRACT: Characteristics of children (n=296) referred to a psychiatric outpatient facility for evaluation of behavioral and school-learning problems were compared to classroom placement recommendations made by a school interdisciplinary team. Results indicate general trends in the relationship between placement options and the incidence and severity of behavioral profiles. (Author/DB)

    ABSTRACT: The authors examined platelet alpha 2-adrenergic receptor binding to 3H-yohimbine and several personality variables in 58 adult males in a campus community. Subjects with high receptor Bmax levels exhibited personality traits of less social inhibition and more sensation seeking and thrill seeking behavior, were more playful and autonomous, and came from healthier, more intact families. The results also suggested that high affinity states of platelet alpha 2-adrenergic receptors (low Kd) correlate with traits suggestive of stability, i.e., Autonomy, Dominance, Nurturance, Order, Succorance, and General Sensation Seeking Scale of Zuckerman, while low affinity states (high Kd) of platelet alpha 2-receptors correlate with psychopathological traits of Dependence, Exhibitionism, and Paranoia.

    ABSTRACT: The authors examined platelet MAO activity and several personality variables in 58 non-clinic-referred healthy adult males. The psychological tests administered consisted of the Minnesota Multiphasic Personality Inventory, the Personality Research Form-E, and the Zuckerman Sensation Seeking Scale. The findings replicated previous findings in the literature.

    ABSTRACT: Platelet monoamine oxidase (MAO) activity was studied in 22 boys diagnosed as having attention deficit disorder with hyperactivity and 12 healthy control boys admitted to a clinical research center and placed on a diet low in monoamines. The hyperactive boys had lower platelet MAO activity than controls, and MAO activity was related to performance on the Matching Familiar Figures Test (MFF) and the Continuous Performance Test (CPT), which yield scores sensitive to impulsivity and inattention. Furthermore, it was negatively related, in hyperactive boys only, to two tests of reading and spelling achievement. Administration of d-amphetamine and placebo in a double-blind crossover design did not significantly raise MAO levels above baseline and was minimally related to improved performance on the MFF and CPT.

    ABSTRACT: The effects of inpatient vs. outpatient status on change in educational placement were examined for a sample of 185 inpatients and 351 outpatients evaluated at a psychiatric facility. Within thesame diagnostic categories, inpatients tended to receceive higher percentages of changes to more-restrictive educational settings than outpatients following evaluation, although such a downward trend was noted for the latter sample as well. The limitations of psychiatric diagnosis to school personnel when making educational placement decisions was discussed.

    ABSTRACT: This study evaluated the psychoeducational reports of 205 children who were referred to the UCLA Neuropsychiatric Hospital for evaluation of academic achievement problems. Factor analysis of the report data indentified a medical factor, a school history factor, and a family factor. Following factor analysis, all three factors as well as measures of cognitive functioning and academic achievement were entered into a discriminant analysis in order to determine which variables, if any, helped predict the educational placement finally to be recommended for each child at the end of the individual psychoeducational work-up. Statistical analysis indicated different results for each of four educational placement options, the greatest predictability being associated with regular classroom placement. Across all placements, the variable that allowed for the greatest accuracy in predicting educational programming recommendations was academic achievement, measured as mean achievement score on standardized achievement tests.

    ABSTRACT: Diagnostic related groups (DRGs) are being adopted as a practical tool in psychiatric classification, as well as a means of reducing health care costs. This study highlights a step-by-step description of the development of 16 outpatient and 14 inpatient DRGs from DSM-III Axis I and Axis II diagnoses on a sample of 591 children (ages 6-14). A plan for the application of diagnostic rules is presented, and issues of generalizability among different treatment populations are discussed.

    ABSTRACT: Although prospective payment using diagnostic related groups (DRGs) has been implemented for certain medical services during the past year, psychiatry in general and child psychiatry services in particular have been exempted from such forms of reimbursement. Since it is generally expected that psychiatry will not continue to be so exempted indefinitely, a preliminary study of 15 potential DRGs in a group of 184 children who received inpatient care were compared with respect to their mean length of hospital admission. Implications of these data for mental health policy are discussed.
