Effects of combining feedback and hypothesis-testing on the quality of simulated child sexual abuse interviews with avatars among Chinese university students

Abstract

Previous research has shown that simulation training using avatars with repeated feedback improves child sexual abuse interview quality. The present study added a hypothesis-testing intervention and examined if the combination of two interventions, feedback and hypothesis-testing, would improve interview quality compared to no intervention and to either intervention alone. Eighty-one Chinese university students were randomly assigned to a control, feedback, hypothesis-testing, or the combination of feedback and hypothesis-testing group and conducted five simulated child sexual abuse interviews online. Depending on the assigned group, feedback on the outcome of the cases and question types used in the interview were provided after each interview, and/or the participants built hypotheses based on preliminary case information before each interview. The combined interventions group and feedback group showed a higher proportion of recommended questions and correct details from the 3rd interview onward compared to the hypothesis-building and control groups. The difference between the number of correct conclusions was not significant. hypothesis-testing alone exacerbated the use of non-recommended questions over time. The results show that hypothesis-testing may impact question types used negatively but not when combined with feedback. The potential reasons for hypothesis-testing alone not being effective and the differences between the present and previous studies were discussed.

White Paper on Forensic Child Interviewing: Research-based recommendations by the European Association of Psychology and Law

“…that a child has been abused), interviewers are urged to explicitly pose and investigate alternative hypotheses about the origin of the allegation (e.g. the statement is mistaken or fabricated) and other aspects of the surrounding situation (Zhang et al, 2023). In this way, interviewers are seeking to practise in a way that is 'consciously objective' (Lacey & Nunkoosing, 2022).…”

“…Finally, there is a significant amount of emerging research reviewing of the use of digital technology innovations to support interviewers. These innovations include learning opportunities using simulations and avatars (Haginoya et al, 2023;Hassan et al, 2022;Krause et al, 2017;Pompedda et al, 2015Pompedda et al, , 2022Salehi et al, 2022;Zhang et al, 2023) as well as self-paced or short training modules (Casey & Powell, 2022;Yan et al, 2023), all of which can be repeated and provide feedback. One even tested an automated question classification system within an avatar interview (Haginoya et al, 2023).…”
