PTSD symptom severity and impulsivity among firefighters: Associations with alcohol use

Abstract

Firefighters represent a unique population at high risk for trauma exposure, posttraumatic stress disorder (PTSD), and alcohol use. This study explored the main and interactive effects of PTSD symptom severity and impulsivity with regard to alcohol use severity. We hypothesized that higher levels of PTSD symptom severity and impulsivity would be related to greater alcohol use severity. Covariates included trauma load, depressive symptom severity, and romantic relationship status. The sample was comprised of 654 firefighters (Mage = 38.65, SD = 8.60) who endorsed exposure to potentially traumatic events and lifetime alcohol use. Firefighters completed an online questionnaire battery. A series of hierarchical regressions was conducted. PTSD symptom severity and impulsivity were significantly, incrementally associated with alcohol use severity, and a significant interactive effect was documented; firefighters with heightened PTSD symptom severity and impulsivity had the highest levels of alcohol use severity. This line of inquiry has great potential to inform prevention and intervention efforts for this vulnerable population. Clinical and research implications are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
