In contrast with previous editions of the BSID, the Bayley-III has strong predictive validity for WPPSI-III IQ at age 4 years in preterm children. This has important implications for more timely evaluation of perinatal interventions, establishment of guidelines for neonatal care, and counseling parents.

Data are presented on standardization and reliability of a behavior‐based measure of attention and self‐control. This computerized test system administers a series of continuous performance tests, as well as measures of response inhibition. The practicality and sturdiness of this approach have allowed for the development of normative data based on the protocols of 1266 children between 4 and 16 years of age. Test‐retest reliability coefficients were high after short intervals (less than 45 days) and 1 year. Originally developed for use in the assessment of children referred for ADD/Hyperactivity, this system has been applied to the evaluation of children with other disorders, as well as to adolescents and adults. Findings are discussed in terms of multimodal assessment, computerization of psychological tests, and the need for cautious standardization.
