Predicting children with pervasive developmental disorders using the Wechsler Intelligence Scale for Children–Third Edition

Abstract

An original combination score (i.e. the sum of Vocabulary and Comprehension subtracted from the sum of Block Design and Digit Span) was created from the four Wechsler Intelligence Scale for Children-Third Edition (WISC-III) subtests identified by discriminant analysis on WISC-III data from 139/129 children with/without pervasive developmental disorders (PDD; mean, 8.3/8.1 years) and its utility examined for predicting PDD. Its best cut-off was 2/3, with sensitivity, specificity, positive and negative predictive values of 0.68, 0.61, 0.65 and 0.64, respectively. The score seems useful, so long as clinicians are aware of its limitations and use it only as a supplemental measure in PDD diagnosis.

Potential Associations Among Alteration of Salivary miRNAs, Saliva Microbiome Structure, and Cognitive Impairments in Autistic Children

“…All participants were assessed by a child and adolescent neuropsychiatrist expert in ASD (RR) with the following instruments: WISC-III (Wechsler Intelligence Scale for Children, III edition) [ 114 ] or WPSSI (Wechsler Preschool and Primary Scale of Intelligence) [ 115 ] as an evaluation of both IQ (Intelligence Quotient) and cognitive functioning, ADOS (Autism Diagnostic Observation Schedule) and ADI-R (Autism Diagnostic Interview–Revised) to evaluate ASD symptoms.…”

Enrichment and Correlation Analysis of Serum miRNAs in Comorbidity Between Arnold-Chiari and Tourette Syndrome Contribute to Clarify Their Molecular Bases

“…(I) Wechsler scale (WISC-III), applied to evaluate Intelligence Quotient (IQ), is a test used to evaluate the intellectual ability of children ranging from 6 to 16 years. To this aim, the assessment provides full-scale intelligence quotient (IQ) scores, as well as Performance IQ and Verbal IQ, two secondary scores (Koyama et al, 2008). (II) The Yale Global Tic Severity Scale (YGTSS) is an 11-item clinician-rated interview, which is able to evaluate motor and phonic tic severity, considering not only the number and frequency, but also the impairment that tics provoke in the patient.…”

WISC‐III profiles of subjects with high‐functioning pervasive developmental disorders who visited child and adolescent psychiatry clinics at a university hospital

“…THE THIRD EDITION of the Wechsler Intelligence Scale for Children (WISC‐III) is commonly used clinically, especially for the diagnosis of pervasive developmental disorders (PDD). However, the usefulness of WISC‐III for this purpose remains controversial 1 . We examined WISC results in cases of high‐functioning PDD (HFPDD).…”
