We evaluated the utility of a brief (5-min) stimulus preference assessment for individuals with developmental disabilities. Participants had noncontingent (free) access to an array of stimuli and could interact with any of the stimuli at any time. Stimuli were never withdrawn or withheld from the participants during a 5-min session. In Experiment 1, the brief preference assessment was conducted for 10 participants to identify differentially preferred stimuli, and reinforcer assessments were conducted to test the reinforcing efficacy of those stimuli identified as highly preferred. In Experiment 2, a comparison was conducted between the brief preference assessment and a commonly used paired-stimulus preference assessment. Collectively, results demonstrated that the brief preference assessment identified stimuli that functioned as reinforcers for a simple operant response, identified preferred stimuli that were differentially effective as reinforcers compared to nonpreferred stimuli, was associated with fewer problem behaviors, and required less time to complete than a commonly used paired-stimulus preference assessment.
我们评估了一种简短（5分钟）的刺激偏好评估对发育障碍个体的实用性。参与者可以无限制地（自由）接触一系列刺激，并可在任何时间与任何刺激进行互动。在5分钟的时间段内，刺激从未从参与者那里撤回或扣留。在实验1中，对10名参与者进行了简短的偏好评估，以识别差异偏好的刺激，并进行强化物评估，以测试那些被确定为高度偏好的刺激的强化效果。在实验2中，对简短偏好评估和常用的配对刺激偏好评估进行了比较。总体而言，结果表明，简短偏好评估识别出了对简单操作性反应起强化作用的刺激，识别出了与非偏好刺激相比作为强化物更具差异有效性的偏好刺激，与较少的问题行为相关，并且比常用的配对刺激偏好评估所需的完成时间更少。
