CAF, Canadian Armed Forces; CGP, Canadian general population; PTSD, post-traumatic stress disorder; AOR, adjusted odds ratio (i.e., adjusted for age, sex, race, marital status, education, and income).

^aPrevalence estimates refer to the proportion of respondents who meet diagnostic criteria for GAD and who also meet diagnostic criteria for the specific comorbid past-year mental disorder.

^bAORs refer to the odds of having the specific past-year comorbid mental condition (independent variable) based on whether the respondent meets diagnostic criteria for past-year GAD (dependent variable).

^cAORs examine the difference in the likelihood of a given past-year mental disorder comorbidity between the CAF and CGP; the CGP is the reference category with an odds of 1.00.

^dPanic disorder and PTSD were assessed differently in the CGP and therefore not comparable with estimates from the CAF survey.
