The paired stimulus preference assessment (PSPA) is commonly used in both research and practice. However, two iterations have been described: a single-presentation arrangement in which each tested stimulus is paired with one another once and a double-presentation arrangement in which each tested stimulus is paired twice with counterbalanced placement. Each arrangement may have different advantages; however, no direct comparison exists. Thus, the purpose of the current study was to conduct both PSPA iterations to determine whether there are differences in the results obtained and which iteration was most efficient regarding time to administer. Seven participants were included, and results demonstrated high degrees of correspondence across preference assessment formats. The average time to administer the single-presentation PSPA (M =6.6 min) was almost half the time to administer a double-presentation PSPA (M =12.9 min), and no significant differences were observed for problem behavior, side biases, or latency to stimulus selection.

评估配对刺激偏好评估的两次迭代

配对刺激偏好评估（PSPA）在研究和实践中都很常用。然而，已经描述了两种迭代：一种是单呈现布置，其中每个测试的刺激彼此配对一次；另一种是双呈现布置，其中每个测试的刺激通过平衡放置配对两次。每种安排可能有不同的优点；然而，不存在直接比较。因此，当前研究的目的是进行两次 PSPA 迭代，以确定所获得的结果是否存在差异，以及哪一次迭代在管理时间方面最有效。七名参与者被纳入其中，结果表明偏好评估格式之间具有高度的一致性。执行单次 PSPA 的平均时间（M  = 6.6 分钟）几乎是执行双次 PSPA 的时间（M  = 12.9 分钟）的一半，并且在问题行为、侧面偏差或延迟方面没有观察到显着差异到刺激选择。
