Table 5.
Overall model fit, beta values, t-values, and p-values are displayed for each diagnostic measure.
| ASC symptom measure | Modulation of activity | |||
|---|---|---|---|---|
| ADIR-TOTAL | R2 = 0.321 | F(1,16) = 7.550 | β = −0.566, t = −2.748 | p = 0.014 |
| ADOS-TOTAL | R2 = 0.264 | F(1,16) = 5.751 | β = −0.514, t = −2.398 | p = 0.029 |
| SCQ | R2 = 0.291 | F(1,16) = 6.569 | β = −0.540, t = −2.563 | p = 0.021 |
| SCQ with ASC and TD group (n = 36) | R2 = 0.422 | F(1,34) = 24.849 | β = −0.650, t = −4.985 | p = 0.0001 |
All values indicate that Modulation of Activity is also a significant predictor of autism severity for each diagnostic measure. Note: Using G* Power 3 (Faul et al., 2007) an effect size (β) of 0.522 was considered significant at 0.8 Power and 18 ppts).
