Does the cognitive interview promote the coherence of narrative accounts in children with and without an intellectual disability?

We examined whether the cognitive interview (CI) procedure enhanced the coherence of narrative accounts provided by children with and without intellectual disabilities (ID), matched on chronological age. Children watched a videotaped magic show; one day later, they were interviewed using the CI or a structured interview (SI). Children interviewed using the CI reported more correct details than those interviewed using the SI. Additionally, children interviewed using the CI reported more contextual background details, more logically ordered sequences, more temporal markers, and fewer inconsistencies in their stories than those interviewed using the SI. However, the CI did not increase the number of story grammar elements compared with the SI. Overall children interviewed with the CI told better stories than those interviewed with the SI. This finding provided further support for the effectiveness of the CI with vulnerable witnesses, particularly children with ID.
