We investigated the separate and combined effects of a behavioral intervention and methylphenidate (Ritalin) on disruptive behavior and task engagement in 3 children with severe to profound mental retardation. The behavioral intervention involved differential reinforcement of appropriate behavior and guided compliance. All 3 children demonstrated decreased disruptive behavior and improved task engagement in response to the response to the behavioral intervention. Two of the 3 children demonstrated similar improvement in response to methylphenidate. Although both interventions were highly effective for these 2 participants, the relative efficacy of the interventions varied between the 2 children. There was no evidence of an additive or synergistic effect of the two interventions, but the high efficacy of each intervention alone limited our ability to detect such effects.
我们调查了行为干预和哌醋甲酯（利他林）对3名重度至极重度智力障碍儿童破坏性行为和任务参与度的单独及联合影响。行为干预包括对恰当行为的差别强化和引导性依从。所有3名儿童在对行为干预做出反应时，破坏性行为均减少，任务参与度得到改善。3名儿童中有2名在使用哌醋甲酯后表现出类似的改善。尽管这两种干预措施对这2名参与者都非常有效，但两种干预措施的相对疗效在这2名儿童之间有所不同。没有证据表明两种干预措施有相加或协同效应，但每种干预措施单独使用时的高效性限制了我们检测此类效应的能力。
