Pilot study on the use of psychotropic medication in persons with mental retardation.

OBJECTIVE: To explore the status of the psychotropic medication in persons with mental retardation 6 years after their deinstitutionalization. METHOD: The authors compared the profiles of psychotropic medication of 60 persons with mental retardation deinstitutionalized (D-sample) from our local mental hospital 6 years ago, to their actual pharmacological profile. Later, we compared our results to the ones of persons with mental retardation on an in-patient (In-sample) unit where existed a concerted team effort to lower the medication when deemed appropriate. RESULTS: Six years post-deinstitutionalization, the authors observed that the same percentage of patients remained on antipsychotic and benzodiazepine medication in our D-sample, and a threefold increase of those using antidepressive medication. However, we observe a general decrease of all types of psychotropic medication in the In-sample with complete withdrawal in a substantial number of patients. CONCLUSIONS: The authors take these pilot data to mean that a concerted team effort at lowering medication in persons with mental retardation makes a significant difference. The possibility of other factors (age, sex, severity of mental retardation, psychiatric diagnosis) explaining the difference in the results is discussed.

Quantifying dimensions in autism: a factor-analytic study.

OBJECTIVE: The objective of this study was to determine whether the phenotypic variation in autism and the related pervasive developmental disorders (PDDs) is a unitary construct or whether it is composed of distinct dimensions of autistic symptoms and measures of level of functioning. METHOD: One hundred twenty-nine children with autism and other forms of PDD from two samples with different inclusion criteria were assessed with the Vineland Adaptive Behavior Scales to measure level of functioning and the Autism Diagnostic Interview to measure severity of autistic behaviors. A factor analysis with varimax rotation was performed on each sample, separately and combined. RESULTS: Two factors emerged; one representing autistic symptoms and another representing level of functioning. The factor structure was remarkably similar and robust to variations in ascertainment and inclusion criteria between the samples. The validity of the distinction was supported by differences between males and females on the symptom factor, but not on the level of functioning factor. IQ was modestly correlated with level of functioning, but not with symptoms. CONCLUSIONS: The phenotypic variation seen in autism/PDD is composed of at least two different dimensions of autistic symptoms and level of functioning. The implications of this dimensional heterogeneity for research, classification, and clinical practice are discussed.

Family correlates of temperament continuity and change across middle childhood.

This paper reports on continuity and change of extreme traits of temperament from age seven to 12 in subgroups selected from a large random sample and on the association of continuity with certain aspects of family functioning. Results suggest a definite degree of stability of extreme temperament over time. Implications of the findings are discussed and directions for future research suggested.
