Note: K10 = Kessler 10; CI = confidence interval; Remote = lifetime but not in past year; Recent = past-year but not in past month; Current = in past month; MDE = major depressive episode; PTSD = posttraumatic stress disorder; GAD = generalized anxiety disorder; PD = panic disorder. See methods for coding of any disorder variable. Totals differ due to differing amounts of missing data by disorder. Cases representing less than 0.1% were excluded due to missing data on K10 score.
