TABLE 3.
Optimism corrected performance and statistical significance of predictor sets p‐values are from the joint test of new predictor variables added to the model
| Outcome | Metric | IQ & Autism Traits | Adaptive functioning & language | Behavioral & emotional problems | Neighborhood characteristics |
|---|---|---|---|---|---|
| No. of predictor variables in model | 4 | 8 | 11 | 14 | |
| Employment and education | C‐statistic | 0.66 (p = 0.012) | 0.68 (p = 0.056) | 0.74 (p = 0.07) | 0.78 (p = 0.08) |
| Friendship | C‐statistic | 0.58 (p = 0.31) | 0.60 (p = 0.053) | 0.60 (p = 0.59) | 0.63 (p = 0.21) |
| Living situation | C‐statistic | 0.87 (p < 0.001) | 0.87 (p = 0.011) | 0.86 (p = 0.30) | 0.85 (p = 0.032) |
| Anxiety (BAI) | Deviance R 2 | 0.01 (p = 0.005) | 0.1 (p < 0.001) | 0.1 (p = 0.07) | 0.00 (p = 0.047) |
| Depression (Log BDI) | R 2 | −0.14 (p = 0.28) | −0.1 (p < 0.001) | −0.1 (p = 0.28) | −0.02 (p = 0.004) |
| Physical health | R 2 | 0.04 (p = 0.20) | 0.22 (p = 0.002) | 0.29 (p = 0.007) | 0.20 (p = 0.80) |
| Psychological domain | R 2 | −0.01 (p = 0.06) | 0.04 (p = 0.007) | 0.02 (p = 0.18) | −0.02 (p = 0.17) |
| Social relationships | R 2 | −0.09 (p = 0.21) | −0.02 (p = 0.04) | −0.13 (p = 0.96) | −0.17 (p = 0.23) |
| Environment | R 2 | −0.04 (p = 0.14) | −0.02 (p = 0.03) | 0.01 (p = 0.008) | 0.06 (p = 0.043) |
Note: The c‐statistic and R‐squared are summaries of overall predictive performance of each model. The maximum possible R‐squared is 1 with r‐squared above 0.25 considered a large overall effect. C‐statistics range from 0.5 to 1 and values above, or close to 0.8, indicate good predictive performance.
