Intercorrelations, means, and standard deviations (SD) for study variables.
| Measure | 1 | 2 | 3 | 4 | Mean (SD) |
|---|---|---|---|---|---|
| 1. Child-reported shyness T1 | - | 0.44 ** | −0.07 | −0.07 | 1.77 (1.02) |
| 2. Self-reported anxiety T2 | - | −0.25 | −0.09 | 152.26 (121.83) | |
| 3. Overall frontal alpha power T2 | - | 0.70 ** | 0.58 (0.15) | ||
| 4. Overall temporal alpha power T2 | - | 0.89 (0.12) |
SD = standard deviation; T1 = preoperative visit; T2 = day of surgery visit, ** p < 0.001; 1 = Child-reported shyness T1; 2 = Self-reported anxiety T2; 3 = Overall frontal alpha power T2; 4 = Overall temporal alpha power T2.
