Infant and Pre-school Developmental Screening Test (JDDST) and Later Development

Abstract

It is generally known that the predictive value of DQ in infancy is rather low for later developmental status at the school age, as far as normal children are concerned (Honzick, M.P., et al., 1984). However, Drillien, D. (1961) and Illingworth, R.S. (1963) have reported that infants with DQ below 70 tended to stay under 70 at school age and they suggest the possibility of the prediction of later mental retardation from devleopmental tests during infancy. The present study was conducted in order to investigate the long-term validity of the Japanese version of Denver Developmental Screening Test (JDDST) by the follow-up of the standardization subjects after 6 to 8 years.
