Bayley Mental Psychomotor Developmental Indices Scores of 61 Neonatal Intensive Care Unit Graduates were examined to investigate whether a predicted early developmental lag would occur followed by an increase or "catch-up" over time. Results indicated that no significant changes occurred over time; however, mental (Bayley MDI) scores were lower than motor (Bayley PDI) scores particularly at the 4- and 22-month test age. Gross motor, fine motor, social, cognitive, and language development was also investigated to see whether expected differences among these domains occurred over time. Results indicated that gross motor scores were greater than all other domains. Ethnicity, birth weight, gestational age, socioeconomic status, language spoken at home, generation of the mother and father from Mexico were analyzed to find the best predictors of 22-month outcome in each of the domains. Generation of mother from Mexico was found to be the best predictor of gross motor skills (17% of the variance accounted for).
