PSP may additionally face moral transgressions in the workplace (e.g., witnessing human suffering, working within broken systems), heightening the risk of moral injury (MI) in this population. Research among military personnel and health care workers shows an association between MI and PTSD; however, less is known about the association between these constructs among PSP. Canadian PSP completed an online survey between June 2022 and June 2023, including a demographic questionnaire and measures of PTSD, MI, dissociation, depression, anxiety, stress, and childhood adversity. Latent variable structural equation modeling (SEM) was performed to ascertain the impact of a latent MI construct (i.e., shame, trust violation, functional impairment) on a latent PTSD construct (i.e., intrusions, avoidance, negative alterations in cognition and mood, hyperreactivity, depersonalization, derealization). Sex, age, depression, anxiety, stress, and childhood adversity were included as covariates. A total of 314 PSP were included in the data analysis. A latent variable SEM regressing PTSD onto MI and including covariates accounted for 83.7% of the variance in PTSD. MI was the strongest predictor compared to all covariates and was significantly associated with PTSD symptoms, \u03b2 =\u00a0.506, <jats:italic>p<\/jats:italic> &lt;\u00a0.001, above and beyond the impacts of sex, age, depression, anxiety, stress, and childhood adversity. These findings are consistent with research among military members and health care providers and highlight the importance of further exploring MI among PSP.<\/jats:p>","DOI":"10.1002\/jts.23122","type":"journal-article","created":{"date-parts":[[2024,12,17]],"date-time":"2024-12-17T05:35:12Z","timestamp":1734413712000},"page":"272-283","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Exploring the association between moral injury and posttraumatic stress symptoms among Canadian public safety personnel"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7482-0656","authenticated-orcid":false,"given":"Andrea M.","family":"D'Alessandro\u2010Lowe","sequence":"first","affiliation":[{"name":"Department of Psychology, Neuroscience &amp;
