Virtual agent-mediated appraisal training: A single case series among Dutch firefighters

Background: First responders are a prime example of professionals that are at a high risk of
being exposed to traumatic experiences. Reappraisal as a coping strategy might help first
responders to better cope with their emotional responses to traumatic events.
Objective: This study investigated the effects of repeated sessions of a digital reappraisal
training among seven firefighters. The training consisted of four sessions supported by a
virtual agent, conducted at home or at work, over a two-week period in a single case series.
Method: Sixteen data points were collected from each participant in the eight days pre- and
post-training.
Results: Significantly more themes were used at post-training than at pre-training, implying
more flexibility and confirming the main hypothesis of the study. Negative side effects were
not reported during or in the week after the training.
Conclusions: More controlled studies into the short- and long-term effects of a training of
this nature are needed. Furthermore, it provides a reference for developers in this field.
