A stimulus preference assessment (SPA) is a fundamental tool used by practitioners to predict stimuli that function as reinforcers. The Behavior Analyst Certification Board (BACB) requires that all certified behavior analysts and behavioral technicians be trained in SPA methodology (BACB, 2017). SPA procedures are used by nearly 9 out of 10 behavior analysts in the field (Graff & Karsten, 2012). Over the last 4 decades, there has been a litany of research on SPA procedures. Despite the universality of training, application, and research, discussions on the selection of SPA procedures have been sparse. Two peer-reviewed articles have focused on clinical decision making in the selection of SPA procedures. Karsten et al. (2011) introduced an in situ decision-making model, whereas Virues-Ortega et al. (2014) developed an a priori algorithm based on client and stimuli characteristics. The SPADS addresses the limitations of prior models by considering the effects of stimuli dimensions, client characteristics, relative administration times, and the outcomes agreement between two potentially efficacious, context-specfic SPA procedures.

刺激偏好评估 (SPA) 是从业者用来预测充当强化物的刺激的基本工具。行为分析师认证委员会 (BACB) 要求所有经过认证的行为分析师和行为技术人员都接受 SPA 方法的培训（BACB，2017）。该领域的 10 位行为分析师中有近 9 位使用 SPA 程序（Graff & Karsten，2012）。在过去的 4 年中，对 SPA 程序进行了一系列研究。尽管培训、应用和研究具有普遍性，但关于 SPA 程序选择的讨论却很少。两篇同行评议的文章侧重于选择 SPA 程序的临床决策。卡斯滕等人。（2011）引入了原位决策模型，而 Virues-Ortega 等人。(2014) 开发了一种基于客户和刺激特征的先验算法。SPADS 通过考虑刺激维度、客户特征、相对管理时间以及两个潜在有效的、特定于上下文的 SPA 程序之间的结果一致性来解决先前模型的局限性。
