Prof. Lyon awarded $2 mil. NIH grant

Lyon will identify best practices for interviewing children about maltreatment

The National Institute of Child Health and Development (NIH) has awarded USC Law Professor Thomas Lyon a $2 million grant to refine and test the protocol he developed to interview maltreated children about their abuse – methods he developed with the support of a previous $1.7 million NIH grant.

The five-year grant comes on the heels of Lyon completing NIH-supported research on maltreated children’s reluctance to disclose their abuse.  Supporting the work is Lyon’s unparalleled access to thousands of maltreated children under the Los Angeles Juvenile Court’s jurisdiction and successful recruitment of comparable non-maltreated children.  

Working with researchers from the University of California, Irvine, and the University of Toronto, Lyon perfected a protocol that encourages children to reveal truthful information without increasing the risks of suggestibility or influence.  Two California agencies that train forensic interviewers and law enforcement statewide have adopted the protocol.

“We’re now devising new methods for increasing children’s willingness to disclose, and studying how different types of questions either suppress details or lead to false reports,” said Lyon.  “We will take these studies into the field to test the efficacy of approaches we’ve perfected in the lab.”

Lyon’s recent research demonstrates that legal approaches to qualifying children to testify are unnecessarily difficult and fail to predict whether children will testify honestly.  He has also identified a simplified means of qualifying children to testify, which attorneys can use in court.

“Some legal authorities feel children are too suggestible and that you can’t believe them, while others argue abused children are too scared to disclose,” says Lyon.  “We’ve shown that a promise to tell the truth increases children’s honesty, and that the right kind of rapport building increases children’s productivity.  We’re now working on other methods to improve their performance.  Our goal is to establish evidence-based best practices for facilitating disclosure while avoiding false allegations.”
