TABLE 3.
Logistic regression analysis of anxiety levels (age 13), gaming frequency (age 13), gaming disorder symptoms (age 13), and gaming disorder diagnosis (diagnosed vs. not diagnosed) at age 14.
| Independent variables | B (SE) | Wald | Odds ratio | 95% CI |
| 1. Anxiety (age 13) | 0.01 (0.03) | 7.52** | 1.01 | (1.00, 1.02) |
| 2. Gaming disorder symptoms (age 13) | 0.40 (0.02) | 551.18** | 1.50 | (1.45, 1.55) |
| 3. Gaming frequency (not at all) | – | 43.70 | – | – |
| 4. Gaming frequency (1–3 times per month) | −0.17 (0.20) | 0.70 | 0.85 | (0.57, 1.25) |
| 5. Gaming frequency (once a week) | −0.02 (0.16) | 0.01 | 0.99 | (0.72, 1.35) |
| 6. Gaming frequency (several times a week) | 0.63 (0.13) | 24.06** | 1.88 | (1.46, 2.42) |

**p < 0.01; Nagelkerke R2 = 0.25; 95% CI. Gaming frequency (not at all) was used as the reference point for subsequent categories of gaming frequency.
