Perceived Family Environments of Depressed and Anxious Children: Child's and Maternal Figure's Perspectives

This study examined perceived environment among families with a depressed, depressed and anxious, anxious, or normal child from the 4th to 7th grades. Fifty-one such children were classified according to criteria from the K- SADS and a set of self-ratings of depression and anxiety. Results showed that children in all three diagnostic groups, and to a lesser extent their mothers, experienced their families as more distressed on a host of dimensions relative to controls. In addition, significant differences were found between families with a depressed and anxious child and those with an anxious child. Discriminant function analyses revealed that 68.63 % of the youngsters could be classified correctly into depressed and anxious groups on the basis of their family ratings alone.

Dementia in adults with Down syndrome: Diagnostic challenges

Although dementia associated with Down syndrome is often presumed to be progressive and irreversible, variations in disease course have been described. In addition, prevalence rates have varied widely among studies. This interim report is a description of the status of 70 adults with Down syndrome who are being followed for signs of dementia. Of the 70, 12 met all criteria for dementia, 40 met subsets of criteria, and 18 met no criteria. Information is provided on instruments used, rationale for choice and revision of instruments as well as criteria used to identify dementia and changes in the status of the participants. The results suggest that extreme care is needed when diagnosing dementia in adults with Down syndrome, for both clinical and research purposes.

The Brief Psychiatric Rating Scale for Children (BPRS-C): Validity and Reliability of an Anchored Version

OBJECTIVE Because the accuracy of problems reported by referred children may be compromised by their academic, cognitive, or motivational limitations, clinician rating forms may contribute to the accurate assessment of youth adjustment. One such measure, the 21-item Brief Psychiatric Rating Scale for Children (BPRS-C), received psychometric study to estimate its potential contribution to the measurement of symptom dimensions. BPRS-C reliability and concurrent validity were calculated for youths who were receiving psychiatric services within a medical school department. METHOD Five hundred forty-seven children aged 3 to 18 years were rated by faculty or trainees; a subsample of 90 was concurrently rated by two observers. BPRS-C psychometric performance was demonstrated through interrater agreement, factor analysis, and multivariate analyses of variance across seven diagnosis-based groups. RESULTS Although items and scales demonstrated substantial reliability and concurrent validity, item factor analysis revealed a few apparent errors in item-to-scale assignment. These errors were minimized by the use of three new second-order factor-derived scales: Internalization, Developmental Maladjustment, and Externalization. CONCLUSIONS The BPRS-C can be easily integrated into academic clinical practice and is a reliable and valid method of child description. Additional study of three new BPRS-C factor scales and the application of the BPRS-C to the quantification of clinician observation of child symptomatic status are warranted.

Aging in adults with intellectual disabilities.

A cross-sequential design was used to examine changes related to aging in adults with and without Down syndrome (ns = 55 and 75, respectively). Adults received yearly neuropsychological and medical evaluations. Support for precocious aging in adults with Down syndrome was evident only on a test of verbal fluency, with weaker support obtained on a test of fine-motor skills. Cross-sectional age differences for all adults were obtained on tests of memory and community living skills. General intellectual level, gender, and psychiatric status were consistently related to performance, indicating the need to examine such mediating variables in studies on aging.

Assessment of orientation: relationship between informant report and direct measures.

Although informant reports of everyday functioning are often used in dementia assessments, the actual correspondence between such indirect reports of functioning and actual performance has not been examined. Orientation results on the Dementia Questionnaire for Mentally Retarded Persons were compared to those obtained in direct assessment of orientation of 138 adults with mental retardation. Fair to good agreement was found between informant report and direct assessment. However, for some orientation items, nonverbal IQ, cause of mental retardation, and age affected the level of agreement. Thus, both informant report and direct measures of orientation are necessary in dementia assessments, and further work is needed on informant scale validation.
