D-Amphetamine 60mg + Therapy
During the 16 weeks of outpatient treatment, participants took three capsules daily (two in the morning, one in the afternoon). All active and placebo capsules were identical in appearance and each contained 50mg riboflavin for subsequent evaluation of medication compliance. Medication administration was initiated during a 5 day run-up period. d-Amphetamine sustained release (SR) (Dexedrine Spansules) started at 15 mg (day 1-2), increased to 30mg (day3; 15mg, BID), 45mg (day4; 15mg, TID), and 60mg (day5; 15mg bid plus 30mg qd). A 5-day dose reduction schedule occurred at week 17. Manual-based, cognitive-behavioral therapy was provided for 1 hour each week by master's-level therapists. The cognitive-behavioral therapy emphasized relapse prevention and coping skills.
Modafinil 400mg + Therapy
During the 16 weeks of outpatient treatment, participants took three capsules daily (two in the morning, one in the afternoon). All active and placebo capsules were identical in appearance and each contained 50mg riboflavin for subsequent evaluation of medication compliance. Medication administration was initiated during a 5 day run-up period. Modafinil started at 200mg (day1) and increased to 400mg (days2-5). A 5-day dose reduction schedule occurred at week 17. Manual-based,cognitive-behavioral therapy was provided for 1 hour each week by master's-level therapists. The cognitive-behavioral therapy emphasized relapse prevention and coping skills.
Modafinil 200mg + D-Amphetamine 30mg + Therapy
During the 16 weeks of outpatient treatment, participants took three capsules daily (two in the morning, one in the afternoon). All active and placebo capsules were identical in appearance and each contained 50mg riboflavin for subsequent evaluation of medication compliance. Medication administration was initiated during a 5 day run-up period. For the combination condition, dosages of modafinil and d-amphetamine were escalated to one-half of that for the single medication conditions. A 5-day dose reduction schedule occurred at week 17. Manual-based,cognitive-behavioral therapy was provided for 1 hour each week by master's-level therapists. The cognitive-behavioral therapy emphasized relapse prevention and coping skills.
Placebo + Therapy
During the 16 weeks of outpatient treatment, participants took three capsules daily (two in the morning, one in the afternoon). All active and placebo capsules were identical in appearance and each contained 50mg riboflavin for subsequent evaluation of medication compliance.
