Value and Limitations of Infant Tests: An Overview

Parental Estimate of Child's Developmental Level in a High-Risk Population

“…On the other hand, however, the further below 70 the DQ falls, even during infancy, the more highly predictive of life-long developmental disability it becomes. 13 Therefore, a DQ of 69 or less should always be regarded as a significant sign of possible developmental dis¬ ability. Parental descriptions of their chil¬ dren were usually accurate, even though their interpretations frequent¬ ly were not.…”

Commentary on ‘Early developmental intervention programs post hospital discharge to prevent motor and cognitive impairments in preterm infants’

“…With the lack of stability of developmental scores (23) the number of children determined as 'delayed' by this dichotomous method varies from test time to test time. This is in spite of the fact that scores that are in the extremely low range, that is greater than 3 SD below the mean, are fairly stable (33,34).…”

What can they do? A review of practical assessment in Science

“…Thus in the field of cognitive testing in infancy, Honzik (1976) and McCall (1976) both attest to the prolonged and futile attempts to obtain positive correlations between cognitive developmental tests in infancy and later IQ tests. Only with sufficient, independent research work, attesting to the reliability of individual, cognitive infant tests was there a recognition that a heterogeneous and varying range of cognitive skills underlay the performances on individual tests, which did not and would not correlate with IQ tests of later childhood.…”
