4.28 ± 0.45 4.4 (4.0–4.6) |
5.4% | 0.44 | <0.001 |
| Perceived safety | 2.58 ± 1.15 2.0 (2.0–3.0) |
2.90 ± 1.16 3.0 (2.0–4.0) |
12.4% | 0.28 | <0.001 |
| Perceived personal resilience | 3.51 ± 0.69 3.5 (3.1–4.0) |

Data are presented as mean ± standard deviation and median (Q25–Q75). p-value is based on paired sample t Test. Effect size *: 0.2-Small, 0.5-Medium, 0.8-Large. Cohen’s d **: appropriate effect size for the comparison between two means.
