Abstract

The Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS), a neurodevelopmental tool for the cognitive assessment of infants and toddlers, correlates well with the Bayley Scales of Infant Development. In 1993 the Bayley Scales were revised and the second edition published (BSID-II). This study was designed to determine how well the CAT/CLAMS correlates with the BSID-II and its utility in identifying mild and severe cognitive impairment. Sixty-eight infants and toddlers (age range = 14-48 months), referred for suspected developmental delays, were administered the CAT/CLAMS and BSID-II and the results compared. The correlation between the two instruments was strong (r = 0.89, P < 0.0001). The CAT/CLAMS was sensitive (81%) and specific (85%) for detecting overall cognitive impairment (BSID-II less than 70) and was even more sensitive (100%) and specific (96%) in detecting severe cognitive impairment (BSID-II less than 50). The physician using the CAT/CLAMS formulated a clinical impression of cognitive impairment that was sensitive (95%) and specific (84%) compared with formal psychologic testing. The CAT/CLAMS correlates well with the BSID-II. It is useful for detecting and quantifying mild and severe cognitive impairment. It permits the physician to formulate an accurate clinical impression of cognitive impairment consistent with possible mental retardation. (C) 2000 by Elsevier Science Inc.
