Objectives
The current study is a 1-year follow-up analysis of data from a randomized controlled trial of Enhanced Milieu Teaching (EMT) for toddlers with language delays. Outcomes and predictors of child language and parent intervention implementation were examined 6 and 12 months after the end of the intervention.
Methods
Toddlers with language delays were recruited from the community, and 97 toddlers and parents were randomly assigned to receive usual community treatments or a 3-month EMT intervention with parent training. Multiple regression analyses were used to estimate the differences between groups at the 6- and 12-month follow-up periods. A subgroup of participants with receptive and expressive language delays was used in a post hoc moderator analysis of treatment outcomes.
Results
Children in the treatment arm did not differ from children in the control arm at 6- and 12-month follow-ups. However, post hoc analyses revealed that children with receptive-expressive language delays were persistently delayed relative to normative performance throughout the follow-up period.
Conclusions
The immediate effects of the brief delivery of EMT were not sustained over the 1-year follow-up period. However, the short-term intervention may not have been sufficient for children with receptive-expressive delays to develop typical language abilities, suggesting they may need more intensive early intervention. Although this intervention may not be necessary for all children with primary language delays, future research should determine the extent to which children with receptive-expressive delays may benefit from more intensive intervention.
