Enhancing investigative interview training using a child avatar system: a comparative study of interactive environments

The impact of investigative interviews by police and Child Protective Services (CPS) on abused children can be profound, making effective training vital. Quality in these interviews often falls short and current training programs are insufficient in enabling adherence to best practice. We present a system for simulating an interactive environment with alleged abuse victims using a child avatar. The purpose of the system is to improve the quality of investigative interviewing by providing a realistic and engaging training experience for police and CPS personnel. We conducted a user study to assess the efficacy of four interactive platforms: VR, 2D desktop, audio, and text chat. CPS workers and child welfare students rated the quality of experience (QoE), realism, responsiveness, immersion, and flow. We also evaluated perceived learning impact, engagement in learning, self-efficacy, and alignment with best practice guidelines. Our findings indicate VR as superior in four out of five quality aspects, with 66% participants favoring it for immersive, realistic training. Quality of questions posed is crucial to these interviews. Distinguishing between appropriate and inappropriate questions, we achieved 87% balanced accuracy in providing effective feedback using our question classification model. Furthermore, CPS professionals demonstrated superior interview quality compared to non-professionals, independent of the platform.

Awareness of the origin of knowledge predicts child witnesses' recall of alleged sexual and physical abuse

AbstractChildren who understand that knowledge may have different origins produce more information in their free‐recall accounts than children who are less aware of source. We examined whether the tendency to make knowledge attributions was related to the number and proportion of details elicited from child witnesses using open‐ended invitations and whether this relationship varied depending on the number of incidents of abuse reported. The tendency to make knowledge attributions was measured in the presubstantive portion of protocol‐guided interviews with 3‐ to 11‐year‐old alleged victims of abuse. Hierarchical regression analyses revealed that the production of knowledge attribution details was positively related to the proportion of substantive episodic details produced by 3‐ to 6‐year‐olds recalling a single incident and by 3‐ to 11‐year‐olds recalling multiple incidents of abuse. Presubstantive source details were also positively correlated with the amount of source information recalled about incidents of abuse. These findings remained significant after controlling for the children's verbosity, the relative prominence of open‐ended invitations, and the children's ages. © 2003 US Government work.

Enhancing children’s narratives in investigative interviews

Objective: To illustrate the amount of detail that can be elicited from alleged abuse victims using open-ended prompts by closely examining forensic interviews of a 5-year-old and a 15-year-old. Method: Interview prompts in the substantive sections of two forensic interviews were characterized as invitations, cued invitations, directive or option-posing, and the number of details they each elicited was tabulated. Results: In both interviews, open-ended prompts predominated and were distributed throughout the substantive phases of the interviews. Most of the information obtained was elicited using open-ended prompts, which remained equivalently effective throughout the interviews. Reconstruction of the children’s accounts illustrated how successive prompts continued to elicit information. Conclusion: Well-framed open-ended prompts, including those that use details provided by the child as cues, elicit narrative accounts from children of all ages. Because such information is more likely to be accurate, investigators are urged to rely more extensively on open-ended prompts.
