ABSTRACT
Examined the impact of late-afternoon stimulant dosing on parent and parent-child domains. Twenty-one children with attention deficit hyperactivity disorder (ADHD) participated in a double-blind, placebo-controlled medication assessment comparing varying doses of methylphenidate (MPH) and Adderall in the context of an intensive treatment program. Children received varying doses of stimulant medication, including active medication or placebo at 3:30 p.m. daily. Parent ratings of their mood, pleasantness of parent-child interactions, and perceived parenting effectiveness and successfulness were obtained each evening. Effective medication doses had a beneficial impact on parent-child domains (e.g., parent-child interactions) but did not significantly affect non-child-related parent variables (e.g., negative affect [NA]). Findings suggested that doses with beneficial effects lasting into the evening improved parent reports of the pleasantness of parent-child interactions but were insufficient to produce positive changes in parent functioning.
