A literature search identified 17 articles reporting data on 34 subjects who engaged in precursors to severe problem behavior, which we examined to identify topographical and functional characteristics. Unintelligible vocalization was the most common precursor to aggression (27%) and property destruction (29%), whereas self- or nondirected movement was the most common precursor to SIB (32%). Unintelligible vocalization and object-directed movement were the most common precursors to behavior maintained by social-positive reinforcement (27% each), and unintelligible vocalization was the most common precursor to behavior maintained by social-negative reinforcement (29%). Only one precursor was reported for behavior maintained by automatic reinforcement.
文献检索确定了 17 篇报告了 34 名参与者进行严重问题行为前体的数据的文章，我们对这些数据进行了研究，以确定其地形和功能特征。无法理解的发声是攻击行为（27%）和财产破坏（29%）最常见的前体，而自我或非定向运动是自我伤害行为（SIB）（32%）最常见的前体。无法理解的发声和物体定向运动是由社会正强化维持的行为（各 27%）最常见的前体，无法理解的发声是由社会负强化维持的行为（29%）最常见的前体。只有一种前体被报告为自动强化维持的行为。
