Introduction: In 2016, the federal government recognized the unique challenges faced by public safety professionals and called for research on operational stress injuries. Since then, studies on the health and wellness of paramedics, firefighters, police officers, and correctional officers have expanded. However, public safety communicators—such as 911 operators, dispatchers, and tactical radio personnel—have received little attention despite experiencing high levels of burnout and PTSD. The study supporting this presentation addresses this gap. Objective: This presentation will (1) examine health and wellness outcomes and determinants for communicators in Alberta and (2) highlight communicators’ primary sources of occupational stress and job satisfaction. Our working hypothesis assumed that the prevalence of PTSD among communicators was comparable to that of other first responders. We also anticipated that organizational factors would be the primary source of stress for communicators. Methods: The research team employed a trauma-informed approach, a social-ecological model, and a mixed-method explanatory sequential design to survey (n=190) and interview (n=73) communicators across Alberta’s fire and police services. The trauma-informed approach fostered collaboration with agencies and participants vulnerable to high stress. Meanwhile, the social-ecological model enabled an analysis of health and wellness from socio-cultural, institutional, and structural perspectives. The explanatory sequential design gave a deeper understanding of survey findings by contextualizing them with qualitative data. Results: The findings indicate that communicators experience a high prevalence of stress, anxiety, PTSD, and suicidal ideation, comparable to other public safety professionals. As predicted, organizational issues—particularly those related to supervisors and leadership—are a significant source of stress for communicators. The research also revealed insights into shift-work and NG911. Conclusions: This study provides the first evidence-based assessment of communicators’ health and stressors in Alberta, positioning Canada as a key contributor to emergency communication research. The findings offer insights for improving work practices and training, ultimately fostering a healthier, more resilient workforce that benefits both communicators and the communities they serve.
