Clinical Adaptive Test/Clinical Linguistic Auditory Milestone Scale in early cognitive assessment.

Correlations between the Clinical Adaptive Test/Clinical Linguistic Auditory Milestone Scale (CAT/CLAMS) and the Bayley Scales of Infant Development--Mental Scale (BSID) were examined in 61 infants and toddlers with suspected developmental delay. Highly significant correlations were found between the two instruments. Gender, race, and gestational age did not influence the relationship between CAT/CLAMS and BSID scores. The CAT/CLAMS was both sensitive (88%) and specific (67%) for mental retardation (BSID < 70). The CAT/CLAMS correlates with the BSID and can be used as an instrument for detecting cognitive delay.
