title: Relative treatment effects of two prelinguistic communication interventions on language development in toddlers with developmental delays vary by maternal characteristics.
abstract: This paper tests whether two prelinguistic communication interventions have a differential effect on productive and receptive language development 6 and 12 months after the end of treatment. We predicted that treatment effects on language development would vary as a function of pretreatment maternal responsivity or amount of mothers' formal education. Fifty-eight prelinguistic children with developmental delays and their mothers participated in the study. Children were randomly assigned to one of two staff-implemented treatments that were designed to increase intentional communication ability. Results confirmed the prediction that treatment effects on children's receptive and expressive language 6 and 12 months after the end of interventions vary as a function of pretreatment maternal responsivity and education level.
