Erratum

A correction should be made to the confidence intervals stated in the abstract, as they do not reflect those reported in the manuscript body. It was stated that "Mean AQ score for the nonclinical population was 16.94 (95 % CI 11.6, 20.0), while mean AQ score for the clinical population with ASC was found to be 35.19 (95 % CI 27.6, 41.1)." In fact, the first set of confidence intervals should read (95 % CI 16.4, 17.4) for the nonclinical sample, and the second should read (95 % CI 34.5, 35.9) for those with ASC.
