Self-injurious behavior (SIB) can be maintained through negative reinforcement when, in the context of training or task requirements, it produces escape as a consequence. Several studies have demonstrated methods for identifying and treating SIB maintained by negative reinforcement; however, few analyses of the establishing operations associated with demand situations have been conducted. The current series of studies illustrates a method for identifying some establishing operations for escape by systematically altering certain dimensions of the demand context while maintaining an escape contingency for SIB. Dimensions assessed in these studies included task novelty, duration of instructional sessions, and rate of task presentation. Data indicate that these variables can have establishing properties for behavior maintained by escape. Implications of the results are discussed, as are potential refinements and extensions of the assessment procedures.
自伤行为（SIB）在训练或任务要求的背景下，产生逃避后果时，可能通过负强化来维持。有几项研究已经证明了识别和治疗由负强化维持的 SIB 的方法；然而，与需求情境相关的建立操作的分析很少。本系列研究说明了一种通过系统改变需求情境的某些维度，同时保持 SIB 的逃避应急条件，来识别一些逃避建立操作的方法。这些研究评估的维度包括任务新颖性、教学环节的持续时间和任务呈现率。数据表明，这些变量对逃避维持的行为具有建立特性。讨论了结果的含义，以及评估程序的潜在改进和扩展。
