视觉探测任务（VPT）是一种用于测量对物质相关刺激的注意偏向的计算机化任务。很少有研究已经检查了VPT的心理测量学特性，尽管担心它表现出差的重测信度和内部一致性。这些问题可能会降低基于VPT性能的推断的置信度。因此，我们试图确定的参数下，酒精VPT的可靠性可能会提高应用最近的经验建议离群值处理，偏差计算和任务设计的焦虑文献。我们重新分析了我们实验室先前发表的3项研究的数据和2个新收集的数据集。我们比较了在屏幕的左/右上方/下方呈现图像的任务，参与者是否对探头的位置或内容做出反应，以及是否使用了与酒精相关的一般图像或个性化图像。在每个VPT中，除了计算试验水平偏倚评分外，我们还应用了先验离群值去除（2和3个标准差和中位绝对差）和数据驱动离群值去除（winsorizing）。在所有的研究和任务的内部一致性和重测信度的注意偏向措施是不够的。有没有一致的改善内部一致性或重测信度作为一个功能的离群值删除方法。我们无法证明酒精VPT的足够可靠性，这进一步支持了这些任务可能不会产生可靠措施的观察结果。未来的研究应该专注于提高这些任务的可靠性，或者放弃它们，转而使用更可靠的替代品。
The visual probe task (VPT) is a computerized task used to measure attentional bias to substance-related stimuli. Little research has examined the psychometric properties of the VPT, despite concerns it demonstrates poor test–retest reliability and internal consistency. These issues can reduce confidence in inferences based on VPT performance. As such, we attempted to identify parameters under which the reliability of the alcohol VPT might be improved by applying recent empirical recommendations for outlier handling, bias calculation, and task design from the anxiety literature. We reanalyzed data from 3 previously published studies in our laboratory and 2 newly collected data sets. We compared tasks which presented images on the left/right of the screen to above/below, whether participants responded to the location or content of the probe, and whether general alcohol-related images or images personalized to the individual were used. In each VPT we also applied a priori outlier removal (2 and 3 standard deviations and median absolute difference) and data-driven outlier removal (winsorizing), in addition to calculating trial-level bias scores. Across all studies and tasks internal consistency and test–retest reliability of attentional bias measures were inadequate. There was no consistent improvement in internal consistency or test–retest reliability as a function of outlier removal methods. We were unable to demonstrate adequate reliability of the alcohol VPT, which further supports observations that these tasks may not yield reliable measures. Future research should focus on improving the reliability of these tasks or abandoning them in favor of more reliable alternatives.
