The Adult ADHD Clinical Diagnostic Scale (ACDS v1.2) will be utilized as the diagnostic tool.
* Has a baseline ADHD-RS score greater than or equal to 28 assessed using adult DSM-IV prompts.
* Understands and is able, willing, and likely to fully comply with the study procedures and restrictions.

Specifically, subjects with mild to moderate forms of Axis I disorders including social phobia and dysthymia may be included while subjects with a lifetime history of psychosis or bipolar disorder will be excluded from participation.
