Table 1.
Characteristics of participants with and without (sub)clinical SAD.
| (Sub)clinical SAD (n = 31) | No SAD (n = 57) | Statistical analysis | |
|---|---|---|---|
| Demographics | |||
| Male / Female (n) | 13 / 18 | 28 / 29 | χ2 = 0.42, p = 0.52 |
| Generation 1 / Generation 2 (n) | 19 / 12 | 27 / 30 | χ2 = 1.56, p = 0.21 |
| Age in years (mean ± SD); range | 33.7 ± 15.5 (9.2–59.6) | 32.9 ± 14.8 (9.6–61.5) | β ± SE = 0.8 ± 3.3, p = 0.80 |
| Estimated IQ (mean ± SD) | 102.2 ± 12.2 | 105.5 ± 10.8 | β ± SE = -3.1 ± 2.4, p = 0.21 |
| Diagnostic information (n) | |||
| Clinical SAD | 15 | 0 | χ2 = 33.3, p < 0.001** |
| Self-report measures (mean ± SD) | |||
| Social anxiety symptoms (z-score) | 2.4 ± 3.3 | 0.7 ± 1.3 | β ± SE = 1.9 ± 0.5, p < 0.001** |
| FNE | 23.0 ± 12.4 | 12.0 ± 7.6 | β ± SE = 10.6 ± 2.2, p < 0.001** |
| Depressive symptoms (z-score) | 0.05 ± 0.9 | −0.6 ± 0.6 | β ± SE = 0.6 ± 0.2, p = 0.001** |
| Trait anxiety | 38.0 ± 9.8 | 33.2 ± 8.6 | β ± SE = 5.0 ± 2.0, p = 0.01* |
SAD: social anxiety disorder; FNE: fear of negative evaluation; STAI: state-trait anxiety inventory; SD: standard deviation.
Sample for dimensional analysis: n = 94 for z-SA, n = 93 for FNE. Data on the presence of subclinical SAD were, due to technical reasons, lost for six family members (remaining sample for categorical analysis: n = 88). ** significant at Bonferroni corrected p-value of 0.0125; * significant at uncorrected p-value of 0.05.
