Forensic Interviewing Techniques in Child Abuse Investigations

Forensic interviewing in child abuse investigations encompasses a suite of structured and semi-structured approaches designed to obtain reliable and comprehensive testimony from children. Central to these methods is the establishment of rapport, the use of developmentally appropriate language and non-suggestive questioning formats, and a protocol-driven progression from open-ended invitations to more focused prompts where necessary. Techniques such as the National Institute for Child Health and Human Development (NICHD) protocol and the Anatomically Detailed Doll method have been widely adopted. Recent advances emphasise the integration of technology—virtual avatars, immersive environments and bio-behavioural monitoring—to enhance interviewer training, reduce children’s anxiety and improve the validity of disclosures. Cross-disciplinary collaboration between psychologists, legal practitioners and technologists underpins these developments, fostering global standards for interviewer practice, safeguarding child welfare and strengthening evidential value in court proceedings.

Research from Nature Portfolio

One study employed a simulated child avatar system to compare immersive and non-immersive platforms for training police and child protection workers. Participants reported superior realism, engagement and self-efficacy when using virtual reality, with 87 per cent accuracy in automated classification of question types, thus demonstrating the potential of avatar-based feedback to refine interviewer skills and adherence to best-practice guidelines. Another investigation monitored acute stress in children testifying in a purpose-built child-friendly court. By measuring heart rate variability alongside self-reported anxiety, researchers found that testimony in traditional interview rooms elicited moderate stress levels, whereas specially designed “decompression” areas significantly reduced physiological arousal. These findings support policy initiatives to adapt legal settings to children’s needs and underscore the role of environment in safeguarding testimonial quality.

Forensic Interviewing Techniques in Child Abuse Investigations publication trend

The graph below shows the total number of articles in forensic interviewing techniques in child abuse investigations across all publications each year (not limited to Nature Index journals).

Technical terms

Forensic interview: A legally structured, ethically guided conversation with a child victim or witness, aimed at eliciting accurate, detailed and reliable information.

Open-ended prompt: A question format that invites the interviewee to describe events in their own words, reducing the risk of suggestive influence.

Avatar simulation: The use of computer-generated characters representing children to create interactive training scenarios for interviewers.

Heart rate variability: A physiological metric reflecting the variation in time intervals between heartbeats, used as an objective index of stress and anxiety.
