Participant characteristics for HF-ASD and TD groups.
| Gender (m:f) | Chronological age (SD) | Nonverbal mental age (SD) | Nonverbal IQ (SD) | SRS total score | SCQ total | |
|---|---|---|---|---|---|---|
| HF-ASD (n = 22) | 19:3 | 6.96 (1.50) | 7.31 (2.00) | 103.14 (14.59) | 79.04 (10.87) | 16.73 (6.56) |
| TD (n = 21) | 16:5 | 6.49 (1.77) | 7.30 (2.48) | 107.05 (10.00) | - |
Notes: Test of equality of means for gender χ2 (1, N = 43) = 0.73, p = 0.39, chronological age, t(41) = 0.94, p = 0.35, and nonverbal mental age, t(41) = 0.01, p = 0.99. SRS = Social Responsiveness Scale; scores on the SRS are reported as t-scores (M = 50, SD = 15). SCQ= Social Communication Questionnaire; scores of 15 or above are considered to meet cut-off for ASD on this screening measure. However, since the initial validation study it has been suggested that a lower cut-off score (e.g., 13 or 11) improves the sensitivity and specificity of the SCQ (Corsello et al., 2007; Snow & Lecavalier, 2008).
