a
For Syndrome scales, at risk is defined as a score of 67 or higher. In addition, normative means (SDs) for these scales are 54 and 6 respectively, for all Syndrome scales except Thought Problems, which has a mean of 53 (SD 6). Normative percentage at risk is approximately 2%.
b
p value is for Wald test from logistic model for IQ group overall or interaction of sex and IQ when reporting results by sex.
