The use of the NICHD protocol to enhance the quantity of details obtained from children with low verbal abilities in investigative interviews: a pilot study.

This study explored the impact of the NICHD protocol to enhance the quantity and content of details reported by children with low verbal abilities. Thirty-four children aged from 6 to 14 were interviewed following their experience of sexual abuse. Half the interviews were conducted using the NICHD protocol. Results indicate that NICHD interviews contained more open-ended prompts and more details overall. Open-ended invitations yielded significantly more detailed responses than did closed-ended questions for both children with low and average verbal abilities. Although children with low verbal abilities provided fewer details than children with average verbal abilities, the NICHD protocol helped them provide detailed responses containing the core elements of the sexual abuse.
