title: The effect of intervention on the free-play experience for mothers and their infants with developmental delay and cerebral palsy.
abstract: An intervention study designed to investigate the effects of one hour of maternal and infant behavior was conducted using experimental and control groups of mothers and their infants with cerebral palsy. Ten mother-infant pairs were in each group; infants ranged in age from 8-32 months. Infants of mothers in the control group received one hour of NDT-based occupational therapy. Two-factor repeated measures analysis of variance with repeated measures of the second factor indicated that the nonverbal instruction methods were significantly more successful in modifying maternal and infant behavior than were the verbal instruction methods. Implications of the results for intervention programs and future research were discussed.
