Prevalence of adverse mental health outcomes*
| Characteristic | N | N (% meeting cut-off score) (95% CI) | Mean (95% CI) |
| Probable common mental disorders (CMDs) (GHQ: cut-off ≥4, scale range: 0–12) | 3967 | 2338 (58.9) (58.1 to 60.8) | 4.9 (4.7 to 5.0) |
| Probable anxiety (GAD-7: cut-off ≥10, scale range: 0–28) | 2471 | 558 (23.2) (21.3 to 25.3) | 6.5 (6.3 to 6.8) |
| Probable depression (PHQ-9: cut-off ≥10, scale range 0–36 | 2466 | 665 (27.3) (25.3 to 29.4) | 7.1 (6.8 to 7.3) |
| Alcohol misuse (AUDIT: cut-off ≥8, scale range 0–45) | 2308 | 278 (10.5) (9.2 to 11.9) | 3.5 (3.3 to 3.7) |
| Probable PTSD (PCL-6: cut-off ≥14, scale range 6–30) | 2447 | 715 (30.2) (28.1 to 32.5) | 11.9 (11.7 to 12.2) |
| Moral injury (MIES: no cut-off, scale range 9–54) | 2399 | (no cut-off) | 15.5 (15.1 to 16.0) |
GHQ was measured in the short survey, while the other measures were included in the optional longer survey, hence the difference in numbers completing each.
