Although functional communication training (FCT) usually includes extinction, withholding reinforcement is not possible or ethical with certain individuals, for some topographies of problem behavior, or in certain contexts. The current study evaluates the effects of two variations of FCT, both without extinction, on problem behavior and communication. Further, the intervention procedures were designed to evaluate participant reactivity to reinforcer parameters (e.g., magnitude, delay, and quality) in the context of the FCT variations. The parameter sensitivity assessments were effective at identifying relevant reinforcer parameters for each participant and both FCT interventions were effective in decreasing problem behavior and increasing communication for all participants. The results demonstrated that FCT was effective regardless of which reinforcer parameter was manipulated. Moreover, all sessions were conducted in participants' homes and caregivers reported high degrees of social validity for the intervention procedures and outcomes.
尽管功能性沟通训练（FCT）通常包括消退，但对于某些个体、某些问题行为的表现形式或某些情境而言，不给予强化是不可能的或不符合伦理道德的。本研究评估了两种不包括消退的FCT变式对问题行为和沟通的影响。此外，干预程序旨在评估在FCT变式情境下参与者对强化物参数（如强度、延迟和质量）的反应性。参数敏感性评估有效地识别了每个参与者的相关强化物参数，并且两种FCT干预措施在减少所有参与者的问题行为和增加沟通方面均有效。结果表明，无论操纵哪种强化物参数，FCT都是有效的。此外，所有疗程均在参与者家中进行，照顾者对干预程序和结果的社会效度评价很高。
