Table 1.
Comparison between the high (HA) and low anxiety (LA) groups.
| High anxiety (n = 24) M (SD) | Low anxiety (n = 23) M (SD) | t, X2 | p | |
|---|---|---|---|---|
| STAI-Trait | 48.96 (4.12) | 25.00 (2.36) | 24.59 | <0.001 |
| Age (in years) | 23.96 (2.29) | 24.00 (2.78) | −0.06 | 0.955 |
| Handedness | 21 right | 23 right | 3.07 | 0.215 |
| STAI-State | 37.17 (5.51) | 29.04 (5.63) | 5.00 | <0.001 |
| ASI | 39.75 (16.02) | 14.04 (11.28) | 6.34 | <0.001 |
| TLES | 4.79 (1.69) | 3.39 (1.31) | 3.17 | 0.003 |
| MINI | 14 unremarkable | 23 unremarkable | 12.17 | <0.001 |
To validate sample selection, HA and LA groups were compared with regard to trait anxiety scores (STAI-Trait). For characterization, groups were compared with regard to age and handedness, self-reported current anxiety (STAI-State), fear of anxiety-related bodily sensations (ASI), experience of threatening life-events (TLES), and psychological difficulties (MINI). Descriptive statistics for each measure and group, X2- and t-test statistics for the group comparison, and corresponding significance values are displayed. Significant comparisons are marked in bold.
