Adjusted T scores for the nine SCL-90-R dimensions and global indices. Where necessary (i.e., heterogeneous variance between the groups), the Welch test was used instead of the T test.

| Global Severity Index (GSI) | 60.0 (58.07–61.95) | 64.4 (60.72–68.10) | –2.11 | 0.028 |
| Positive Symptom Total (PST) | 56.1 (54.13–58.06) | 61.1 (57.35–64.87) | –2.49 | 0.014 |

↵* With Bonferroni correction, p values < 0.0055 (0.05/9) are considered statistically significant for each of the 9 individual dimensions.
