Comparison of TAS-1, TAS-2, TAS-3, TAS-total, BDI, and BAS scores of patients and controls
| Results | Patients (N = 87) | Controls (N = 88) | P-value |
|---|---|---|---|
| TAS-1 | 17.0 ± 6.2 | 10.3 ± 2.4 | <0.01 |
| TAS-2 | 13.0 ± 4.2 | 10.2 ± 3.3 | <0.01 |
| TAS-3 | 22.0 ± 4.0 | 16.3 ± 4.1 | <0.01 |
| TAS-total | 51.8 ± 10.6 | 36.7 ± 7.0 | <0.01 |
| Alexithymics (TAS-20 ≥61) | 19 | 7 | <0.01 |
| BDI | 13.6 ± 7.8 | 7.4 ± 5.2 | <0.01 |
| Depressed (BDI ≥18) | 29 | 10 | <0.01 |
| BAS | 17.4 ± 11.4 | 9.0 ± 7.1 | <0.01 |
Notes: Independent sample t-test (Student t-test) was used for comparison of numerical data. Scores of both groups are expressed as mean ± SD. The presence of alexithymia and depression among two groups is compared with chi-square analysis.
