We conducted a concurrent‐operant demand assessment (CODA) to identify a hierarchy of preference for demands in 17 individuals who exhibited problem behavior. We presented demands in pairs, with selection between demands serving as the dependent variable. The reinforcing efficacy of escape from the most‐ and least‐selected demands from the CODA was evaluated for 7 participants using progressive‐ratio (PR) schedules. Outcomes from the PR analysis corresponded with the rank order of demands from the CODA. Four of these seven participants were subsequently exposed to a brief CODA with only two items, which consisted of successive presentations of the most‐ and least‐selected demands from the CODA. Outcomes of the brief CODA corresponded with the PR and CODA for 3 out of 4 participants. These results suggest that the CODA might be an effective technology to determine a hierarchy of preference for demands for assessment and treatment purposes.

评估并发需求评估以确定任务偏好

我们进行了一项并行操作需求评估（CODA），以识别17位表现出问题行为的个人对需求的偏好等级。我们成对呈现需求，需求之间的选择用作因变量。使用渐进比率（PR）计划评估了7名参与者从CODA需求最多和最少的需求中逃脱的增强功效。PR分析的结果与CODA的需求等级相对应。随后，这七个参与者中的四个暴露于简短的CODA中，其中只有两个项目，其中包括连续展示CODA中需求最多和最少的需求。简短CODA的结果与PR和CODA相符，占4名参与者中的3名。
