| Variables | Wald | Exp(β) | 95% CI |

| GAD | 4.76* | 5.60 | 1.19–26.32 |
| Behavior inhibitionc | 6.61* | 1.15 | 1.03–1.29 |
Note.
a
Model I: we regress IGD on GAD, controlling for age, gender, and educational level.
b
Model II: behavior inhibition was included as an independent variable to enter the regression Model I.
c
Behavior inhibition: the score of BIS subscale of the Behavioral Inhibition System and Behavioral Approach System Scales (BIS/BAS scales).
*p < .05. **p < .005.
