Attention Deficit Hyperactivity Disorder (ADHD) among longer-term prison inmates is a prevalent, persistent and disabling disorder

Table 4 ANOVA statistics included post hoc IQ adjustments for tests of executive functions. The statistics F, p, and ηp2 presented for ANOVAs without IQ adjustments. On working memory tests, higher scores reflect better results, whereas on Conners' CPT II, higher scores reflect poorer results.
