Psychological Debriefing of Workplace Trauma: A Case Study of the Toronto Transit Commission (TTC)
psychological; debriefing; workplace; trauma; PTSD; lost time
Mental stress resulting from a traumatic event in the workplace has a noteworthy impact on employees. Psychological debriefing is offered to TTC employees as a means of immediate trauma support, however, the usefulness of the intervention is unknown. This thesis explores the debriefing intervention using a mixed methods approach. TTC employees who have experienced a traumatic event were recruited. Post Traumatic Stress Disorder (PTSD) symptom development and time lost from work were compared between debriefed and not debriefed employees. In addition, purposively selected employees were qualitatively interviewed. The quantitative analysis showed no significant differences in PTSD symptomatology or lost time from work between the groups. Despite these results, however, employees who were debriefed had an overall positive perception of the intervention. Further exploration in this area of study would be beneficial to not only the TTC, but to all workplaces at high risk of exposure to traumatic events.
