Forensic interviewers' perceptions of the utility of mock interviews with trained actors as a training tool for child interviewing

How to prepare for conversations with children about suspicions of sexual abuse? Evaluation of an interactive virtual reality training for student teachers

BACKGROUND

Training for child interviewing in case of suspected (sexual) abuse must include ongoing practice, expert feedback and performance evaluation. Computer-based interview simulations including these components have shown efficacy in promoting open-ended questioning skills.

OBJECTIVE

We evaluated ViContact, a training program for childcare professionals on conversations with children in case of suspected abuse.

PARTICIPANTS AND SETTING

110 student teachers were divided into four groups and took part either in a two-hour virtual reality training through verbal interaction with virtual children, followed by automated, personalized feedback (VR), two days of online seminar training on conversation skills, related knowledge and action strategies (ST), a combination of both (ST + VR), or no training (control group, CG).

METHODS

We conducted a pre-registered, randomized-controlled evaluation study. Pre-post changes on three behavioral outcomes in the VR conversations and two questionnaire scores (self-efficacy and - undesirable - naïve confidence in one's own judgment of an abuse suspicion) were analyzed via mixed ANOVA interaction effects.

RESULTS

Combined training vs. CG led to improvements in the proportion of recommended questions (ηp2 = 0.75), supportive utterances (ηp2 = 0.36), and self-efficacy (ηp2 = 0.77; all ps < .001). Both interventions alone improved the proportion of recommended questions (VR: ηp2 = 0.67, ST: ηp2 = 0.68, ps < .001) and self-efficacy (VR: ηp2 = 0.24, ST: ηp2 = 0.65, ps < .001), but not supportive utterances (VR: ηp2 = 0.10, ST: ηp2 = 0.13, both n. s.).

CONCLUSIONS

The combination of VR and ST proved most beneficial. Thus, VR exercises should not replace, but rather complement classical training approaches.

An overview of mock interviews as a training tool for interviewers of children

Mock (simulated) interviews can be used as a safe context for trainee interviewers to learn and practice questioning skills. When mock interviews are designed to reflect the body of scientific evidence on how questioning skills are best learned, research has demonstrated that interviewers acquire relevant and enduring skills. Despite the importance of this exercise in learning interview skill and its prevalence as a learning tool in other fields such as medicine and allied health, there has been relatively little discussion about mock interviews from an educational perspective in investigative interview training. This paper addresses that gap by providing the first comprehensive overview of the way mock interviews have been used in training interviewers of children. We describe the research that supports their utility, and the various ways they can be implemented in training: providing insight to learners; allowing opportunities for practice, feedback, and discussion; and as a standardized way to assess skill change over time. The paper also includes an overview of the cutting-edge use of avatars in mock interviews to enhance efficiency, provide unique learning experiences, and ultimately reduce training costs. We explain why avatars may be particularly useful in basic training, freeing up human trainers to facilitate mock interviews around advanced topics and discussion.
