During the study period, 33% of the active duty personnel had at least 1 mental health–related visit to either a military treatment facility or a civilian psychiatrist. Among those who had a mental health care visit, 70% saw psychiatrists only in military treatment facility settings, 9% saw only civilian psychiatrists, and the remaining 21% used both settings. Those who made mental health care visits were more likely to be female (21% among those with ≥1 visit vs 15% among those with no visit) and married (62% among those with ≥1 visit vs 51% among those with no visit). The Army had a disproportionately higher share of service members with at least 1 mental health care visit (47% compared with 34% among the sample with no mental health care visit).
