A goal of some functional analysis (FA) variations is to reduce assessment time while still maintaining efficacy. This may be especially important when conducting FAs in early intervention programs, where time is a crucial commodity. To that end, we evaluated a model for using the results of the no-interaction condition as a screening for behavioral function and to guide selection of FA test conditions with 20 participants (22 assessments) aged 3 to 7 years old. We used the no-interaction condition to develop hypotheses for both automatic reinforcement and socially mediated reinforcement. The outcome of the no-interaction condition guided the selection of test conditions for the remainder of the FA. We also incorporated methods from prior FA studies (e.g., divided attention) to modify the test conditions. We obtained differentiated results in 91% of assessments, all within 70 min and, as such, extended evidence that an FA can be completed in little time without sacrificing efficacy.
一些功能分析（FA）变体的目标是减少评估时间，同时保持功效。在早期干预计划中进行 FA 时，时间是一种关键资源，这一点尤为重要。为此，我们评估了一种使用无相互作用条件的结果作为行为功能筛查的模型，并指导了 20 名年龄在 3 至 7 岁的参与者（22 次评估）的 FA 测试条件选择。我们使用无相互作用条件来为自动强化和社会中介强化假设提供依据。无相互作用条件的结果指导了 FA 剩余部分的测试条件选择。我们还采用了之前 FA 研究中的方法（例如，分散注意力）来修改测试条件。我们在 91%的评估中获得了不同的结果，所有评估都在 70 分钟内完成，因此，进一步证明 FA 可以在不牺牲功效的情况下在短时间内完成。
