abstract
Firefighters represent a distinct group of first responders that are at heightened risk of developing posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). Assessing the role of transdiagnostic factors that underlie PTSD-AUD associations can inform specialized interventions among this population. This study included urban firefighters (N=657) with probable PTSD-AUD (n=27), probable PTSD-alone (n=35), probable AUD-alone (n=125), and trauma-exposure-only (n=470). Methods: All firefighters completed a self-report, online questionnaire battery. Between group differences in anxiety sensitivity (AS), distress tolerance (DT), mindfulness, and emotional regulation difficulties (ERD) were assessed. It was hypothesized that firefighters with probable PTSD-AUD would endorse elevated AS and ERD, and reduced DT and mindfulness in comparison to all other diagnostic groups. Relationship status was included as a covariate in all comparisons. Results: Firefighters with probable PTSD-AUD endorsed elevated AS and ERD, and reduced DT and mindfulness in comparison to firefighters with trauma-exposure-only and probable AUD-alone. Firefighters with probable PTSD-AUD and probable PTSD-alone did not significantly differ. Conclusions: Given these findings, this line of inquiry has great potential to inform specialized, evidence-based mental health programming among firefighter populations, who represent a unique population susceptible to trauma-exposure, PTSD symptomology, and problematic alcohol use.
