| Correlations | ||||
| Drive | 0.056 | — | — | — |
| RR | 0.396 | 0.309 | — | — |
| FS | 0.251 | 0.636 | 0.477 | — |

Note: BIS, Behavioural Inhibition System; BAS, Behavioural Activation System; RR, Reward Responsiveness; FS, Fun Seeking; SD, standard deviation. All factor loadings were significant at p < 0.001. All correlations between BIS, Drive, RR and FS were significant (all p < 0.001, except for the correlation between BIS and Drive, p = 0.017).
