|---|---|---|---|---|---|
| BIS overall score (sum of subscales) | 58.11 ± 8.14 | 43 | 71 | – | – |
| BIS 1st order attentional subscale | 9.53 ± 2.82 | 5 | 14 | 0.72 | 0.00055 |
| BIS 1st order cognitive instability subscale | 6.32 ± 2.00 | 3 | 9 | 0.75 | 0.00023 |
| BIS 1st order motor subscale | 14.95 ± 1.99 | 11 | 18 | 0.68 | 0.0014 |
| BIS 1st order perseverance subscale | 6.79 ± 1.36 | 4 | 9 | 0.48 | 0.038 |
| BIS 1st order self-control subscale | 10.58 ± 2.55 | 6 | 15 | 0.80 | 4.7 × 10−5 |

R denotes correlation coefficient comparing subscore against overall BIS score (sum of 1st order subscores). P indicates p-value from t-test comparing correlation against zero with df = 17.
