Conceptualising "dose" in paediatric language interventions: Current findings and future directions.

Dose is a particularly important element of treatment for speech and language disorders, yet relatively little is known concerning how best to operationalise dose in clinical settings. This keynote provides an overview of dose as a theoretical and empirical concept and discusses recent findings that question whether "more is better" when treating children with language disorders. Given recent evidence showing that spaced treatments may result in optimal gains for children, I argue that low-frequency therapy sessions can be especially beneficial for children with language disorders when they are highly productive, providing children with high levels of dose.
