There is promising preliminary evidence that suggests that psychological approaches to treatment are effective in individuals with Adult ADHD (see Weiss et al 2008 for a review). So far, however, only one randomised controlled trial of CBT has been carried out (Safren, Otto et al 2005). Thirty-one participants were randomised to receive either CBT and medication as usual or medication alone. Those randomised to CBT (n=16) had significantly lower ADHD symptoms (as rated by an independent investigator), global severity and self-rated symptoms than those on medication only (ps range <0.01 to <0.002). Those in the CBT group also had significantly lower scores on independently- and self-rated measures of mood (ps range <0.01 to 0.04).
