Note. Percentages are based on weighted N, which have been rounded to base 20 for confidentiality purposes as per Statistics Canada’s data release policies. Dashes indicate information that was not assessed and/or not applicable in the general population survey (therefore precluding examining differences across the study populations). GAD = generalized anxiety disorder; PTSD = post-traumatic stress disorder; IPV = intimate partner violence; CI = confidence interval; OR = odds ratio; AOR = odds ratio adjusted for sociodemographic covariates (age, gender, visible minority, marital status, education, and income).
a Only Regular Force personnel who reported having ever been deployed are included in estimates related to deployment-related traumatic events.
