Identification of reinforcers is critical to the effectiveness of behavioral interventions. Stimulus preference assessments (SPA) are a frequently used method to identify putative reinforcers. Given the fluctuating nature of individual preferences, there is need for efficient training of providers that may regularly implement SPAs. The present study evaluated the utility of a web-delivered training with virtual role play to train SPA implementation. This study builds upon previous literature by utilizing a larger sample and incorporating role-play, a component often omitted from other efficient methods of training. Study 1 trained 40 undergraduate students to implement an SPA via web or in vivo. Results suggest both trainings were equivalently effective, and the web-delivered training reduced trainer time by approximately 25 min. Live role-play and feedback was still necessary with web-delivered training, consistent with suggestions that rehearsal and feedback is a vital component of training. Results also suggest web-delivered training may identify areas of weakness following training. A follow-up clinical pilot showed that the web-delivered training was also effective at training eight novice providers to competently implement the SPA with children with ASD in a special education school. This study demonstrates that web-delivered training with virtual role-play is likely another efficient training method for implementation of behavioral procedures.
强化物的识别对于行为干预的有效性至关重要。刺激偏好评估(SPA)是一种常用的识别潜在强化物的方法。鉴于个体偏好的波动性质,需要对可能经常实施SPA的提供者进行有效培训。本研究评估了通过虚拟角色扮演进行网络培训以培训SPA实施的效用。本研究在以往文献的基础上,采用了更大的样本并纳入了角色扮演,而角色扮演是其他有效培训方法中经常省略的一个组成部分。研究1对40名本科生进行培训,使其通过网络或现场实施SPA。结果表明两种培训效果相当,且网络培训使培训师的时间减少了约25分钟。网络培训仍需要现场角色扮演和反馈,这与排练和反馈是培训的重要组成部分的观点一致。结果还表明,网络培训可能会在培训后识别出薄弱环节。一项后续临床试点表明,网络培训在培训八名新手提供者在一所特殊教育学校对患有自闭症谱系障碍(ASD)的儿童有效实施SPA方面也很有效。本研究表明,通过虚拟角色扮演进行网络培训可能是实施行为程序的另一种有效培训方法。
