Mary Morrow‐Tlucak, Claire B. Ernhart, Cherie L. Liddle

Abstract

A modified administration of the Kent Infant Development Scale for infants 6 to 8 mo. old was used in a prospective study of risk factors in infant development. The Mental Development Index and Psychomotor Development Index of the Bayley Scales of Infant Development were also administered at 6 mo., the Mental Index only at 1 and 2 yr. and the Stanford-Binet Intelligence Scale at age 3. The modified administration is described. Concurrent validity with the 6-mo. Bayley scales was substantial. Adequate predictive validity for 1- and 2-yr. Bayley scores and 3-yr. Stanford-Binet IQ was achieved with the Kent as compared to the predictive ability of the 6-mo. Bayley index.
