For the ASD group only, there were significant or near-significant (P <0.06) associations for the anxiety condition (uncued, unpredictable phase) for the remaining variables (listed in order of the value of the correlation coefficients): SCAS-C total anxiety (r = -0.59, P = 0.011), SCAS-C GAD (r = -0.57, P = 0.015), SCAS-P GAD scores (r = -0.46, P = 0.052), SRS Mannerisms (r = -0.45, P = 0.059) and the IU child report (r = -0.45, P = 0.059). This evidence concerns the gene GAD1 and Anxiety.
