*

Significantly different from the percent for any mental disorders at the.05 level, two-sided test

a

The unweighted numbers of respondents with the disorders. Note that the ratios of these numbers to the total sample size generally do not equal the prevalence estimates, as the latter are based on the weighted data.

b

The unweighted numbers of respondents in treatment for the disorders. Note that ratios of these numbers to the numbers of respondents with the disorders generally do not equal the estimates of the percent in treatment, as the latter are based on the weighted data.

c

ADHD: Attention-deficit/hyperactivity disorder
