1This table includes updated data as of July 19, 2007. Updates reflect the latest diagnostic, demographic and raw variable information.
2 Assessed in the Part II sample (n = 5692).
3 Assessed in a random one-third of the Part II sample (n = 2073).
4 Assessed in the Part II sample among respondents in the age range 18-44 (n = 3197).
5 Estimated in the Part II sample. No adjustment is made for the fact that one or more disorders in the category were not assessed for all Part II respondents.
6 The estimated prevalence of any impulse-control disorder is larger than the sum of the individual disorders because the prevalence of intermittent explosive disorder, the only impulsecontrol
disorder that was assessed in the total sample, is reported here for the total sample rather than for the sub-sample of respondents among whom the other impulse-control disorders
were assessed (Part II respondents in the age range 18-44). The estimated prevalence of any impulse-control disorder, in comparison, is estimated in the latter sub-sample. Intermittent
explosive disorder has a considerably higher estimated prevalence in this sub-sample than in the total sample.
7 Disorder with hierarchy
