Significantly higher conditional prevalence of adult ADHD among respondents with a childhood history AD-Only than HD-Only at the .05 level based on a two-sided test
A total of 91 respondents out of the 345 in the sample were judged retrospectively to have met DSM-IV criteria for ADHD in childhood. As these cases were over-sampled from a larger initial sample in selecting respondents to be administered the clinical follow-up interview, the data for all 345 respondents were weighted to adjust for the over-sampling (not only of cases but also of sub-threshold cases). The percentages reported in this table are based on analysis of these weighted data, whereas the sample sizes reported are unweighted. This is why the ratios of observed sub-sample sizes to the total sample size do not correspond to the reported percentages.
