Summary
The first phase was a double-blind crossover design of methylphenidate in the treatment of
adult ADHD. The second phase consisted of an open-label extension trial of methylphenidate in
adult ADHD. It was hypothesized that methylphenidate would prove more effective than placebo
in treating ADHD symptoms during the first phase. It was also hypothesized that
methylphenidate responders from the double-blind trial would continue to benefit from
treatment in the second phase. Improvement would include both ADHD symptoms and social
adjustment.
