This book updates the previous review of research on children’s testimony—reexamining and readdressing how the quality of information provided by young witnesses is affected by the way they are questioned. Drawing upon both experimental and field studies conducted in different countries, it summarizes evidence supporting the effectiveness of the National Institute for Child Health and Human Development (NICHD) Protocol and showcases the Protocol’s superiority over other current interviewing techniques for eliciting detailed and forensically useful content from child complainants. Written with both child protection professionals and researchers in mind, offers advice and opinions drawn from actual investigative interviews as well as academic research. Its insightful chapters cover: children’s testimony; interview and questioning strategies; how investigators typically interview alleged victims; the NICHD Investigative Interview Protocols; the impact that following the Protocol has on interviews and children’s responses; interviewing victims under the age of six; interviewing children with developmental disabilities; using tools and props to complement the Protocol; training and maintaining good interviewing practices; and more. deserves to be read by all practitioners involved in child protection, whether as investigators, interviewers, judges, or lawyers.
