Study Arms (2)
Sequence 1: XR-MAS then placebo
EXPERIMENTALDepending on whether 1) child has had previous medication trial or 2) is on psychotropic medication at time of screening, children will either enter the washout period of 3 days before extended release mixed amphetamine salts (XR-MAS) or placebo (PBO) is initiated or proceed directly to the active treatment sequence they were randomized to. Participants randomized to Sequence 1 first receive treatment with XR-MAR for 3 weeks and then placebo for 3 weeks. Flexible, forced dosing will start at 5 mg/day for the first week, increase to 10 mg/day for the second week and continue to 15 mg/day on the third week. No washout period otherwise occurs (XR-MAS is not clinically suspected to have lingering effects beyond initial dosing/day of administration), including the crossover week to PBO.
Sequence 2 Placebo then XR-MAS
EXPERIMENTALDepending on whether 1) child has had previous medication trial or 2) is on psychotropic medication at time of screening, children will either enter the washout period of 3 days before extended release mixed amphetamine salts (XR-MAS) or placebo (PBO) is initiated or proceed directly to the active treatment sequence they were randomized to.

Flexible, forced dosing will start at 5 mg/day for the first week, increase to 10 mg/day for the second week and continue to 15 mg/day on the third week. No washout period (stimulants are not clinically suspected to have lingering effects beyond initial dosing/day of administration)otherwise occurs, including the crossover week to XR-MAS.
Interventions
XR-MAS given in non-identifying 5 mg capsules with instructions to start 1 capsule (5 mg/d) for one week, then increase to 2 capsules (10 mg/d) for week two, and 3 caps (15 mg/d) for week 3 following flexible, forced titration based on response and tolerance.
PBO given in non-identifying 5 mg capsules with instructions to start 1 capsule (5 mg/d) for one week, then increase to 2 capsules (10 mg/d) for week two, and 3 caps (15 mg/d) for week 3 following flexible, forced titration based on response and tolerance.
