*Significant at the 0.05 level, two-sided test.

^aAssessed in the part II sample.

Reference category is exactly one disorder, unless otherwise indicated with 1.00, –.

^bVariable was dropped from the model due to insufficient sample size.

The degree of freedom for each χ² is based upon the number of group available in each main category.

All models used part II sample.
