MAKS = Mental Health Knowledge Schedule; OMS-WA = Open Minds Survey for Workplace Attitudes; MHSUQ = Mental Health Service Use Questionnaire; RCMP = Royal Canadian Mounted Police. Letters in the cells indicate categories of public safety officers that are significantly different from one another at p < 0.05; e.g., correctional workers “a” reported statistically significantly higher mental health knowledge than municipal/provincial police “b, c,” and RCMP “b, c,” but were not statistically significantly different compared to communication officials “a.”
