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.

Condition Intervention Phase
Attention Deficit Hyperactivity Disorder
Drug: methylphenidate

Arms Assigned Interventions
Experimental: a
This arm was only open to subjects entering the second, open-label phase. All subjects were given open-label methylphenidate. Dosing was flexible.
Drug: methylphenidate
Dosing was flexible and dependent on clinical judgement, AEs and treatment response.
Other Name: ritalin
Experimental: MPH
This is the active treatment arm of the double-blind placebo controlled phase. Patients were begun at 10 mg t.i.d. and the dose increased as necessary until a maximum dose of 60 mg/day was administered. Frequency could be increased and some patients had dosage schedules of 4 to 6 times per day
Drug: methylphenidate
Patients were begun at 10 mg t.i.d. and the dose increased as necessary until a maximum dose of 60 mg/day was administered. Frequency could be increased and some patients had dosage schedules of 4 to 6 times per day
Other Name: ritalin
Placebo Comparator: PBO
This 2 week arm is the placebo part of the crossover design. Subjects receive placebo in a manner similar to the MPH arm. It lasts 2 weeks.
Drug: placebo
Dosing is identical to the MPH arm except that the pills will contain no active medication.

Detailed Description:
All patients received a single-blind week on placebo, followed by a double-blind random assignment crossover trial of methylphenidate and placebo, with each double-blind phase lasting two weeks. Subjects who experienced moderate or marked improvement on methylphenidate would be allowed to enter a long-term, open-label trial. ADHD symptom severity was measured monthly by a structured interview, the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS), Clinical Global Impression - Improvement (CGI-I) and Global Assessment of Functioning (GAF). Social functioning was assessed by the clinician administered version of the Weissman Social Adjustment Scale (WSAS). Dosing was determined by clinical judgement, symptom improvement and AEs.
