Making oral comprehension interventions TIDieR: A narrative synthesis of interventions improving comprehension in children from 1 to 5 years with language difficulties.

Background: Oral comprehension difficulties are prevalent in preschool children with language difficulties and are frequently the target of speech and language therapy (SLT) intervention. To support the implementation of research to practice, there is a need to identify effective interventions for this population and to describe their components. To date, reviews of oral comprehension intervention have not used inclusion criteria aligned with common clinical practice, particularly in the United Kingdom.
