We evaluated antecedent exercise for treating the automatically reinforced problem behavior of 4 individuals with autism. We conducted preference assessments to identify leisure and exercise items that were associated with high levels of engagement and low levels of problem behavior. Next, we conducted three 3-component multiple-schedule sequences: an antecedent-exercise test sequence, a noncontingent leisure-item control sequence, and a social-interaction control sequence. Within each sequence, we used a 3-component multiple schedule to evaluate preintervention, intervention, and postintervention effects. Problem behavior decreased during the postintervention component relative to the preintervention component for 3 of the 4 participants during the exercise-item assessment; however, the effects could not be attributed solely to exercise for 1 of these participants.
我们评估了预先锻炼对治疗 4 名自闭症个体自动强化问题行为的效果。我们进行了偏好评估，以确定与高水平参与和低水平问题行为相关的休闲和锻炼项目。接下来，我们进行了三个三成分多重时间表序列：一个预先锻炼测试序列、一个非关联休闲项目控制序列和一个社会互动控制序列。在每个序列中，我们使用三成分多重时间表来评估干预前、干预中和干预后的效果。在锻炼项目评估中，4 名参与者中有 3 名在干预后阶段相对于干预前阶段的问题行为减少；然而，对于其中一名参与者，这些效果不能仅仅归因于锻炼。
