We evaluated functional communication training (FCT) combined with a chained schedule of reinforcement procedure for the treatment of challenging behavior exhibited by two individuals diagnosed with Asperger syndrome and autism. Following functional analyses that suggested that challenging behavior served multiple functions for both participants, we implemented FCT in which mands for a discriminative stimulus (S(D); wristband) were reinforced with access to the S(D) and all three functional reinforcers. Next, we modified the procedure by incorporating delays to increase ease of implementation and promote toleration of delays to reinforcement. Last, we made additional modifications to the procedure by incorporating a chained schedule of reinforcement such that (a) mands for the wristband were reinforced with access to the wristband and (b) specific mands for respective functional reinforcers were reinforced in the presence of the wristband. The results showed that the procedure successfully treated challenging behavior with multiple functions. Future directions in the evaluation and development of treatments that simultaneously address multiple functions are discussed.
我们评估了功能沟通训练（FCT）与连锁强化程序相结合，用于治疗两名被诊断为阿斯伯格综合征和自闭症患者的挑战性行为。在功能分析表明，挑战性行为对两名参与者都有多种功能后，我们实施了 FCT，其中对辨别刺激（S(D)；腕带）的指令用获得 S(D)和所有三种功能强化物来强化。接下来，我们通过引入延迟来增加实施的便利性，并促进对强化延迟的容忍度，从而修改了程序。最后，我们对程序进行了其他修改，引入了连锁强化程序，使得（a）对腕带的指令用获得腕带来强化，以及（b）在腕带存在的情况下，对各自的功能强化物的特定指令进行强化。结果表明，该程序成功地治疗了具有多种功能的挑战性行为。讨论了在评估和开发同时解决多种功能的治疗方法方面的未来方向。
