Abstract

Aim

To systematically develop and test stimuli for inclusion within the revised Alcohol Expectancy Task (rAET)-a pictographic assessment of alcohol-related beliefs.Using a UK adult sample of regular social drinkers, this paper documents the (1) selection (2)development and (3)testing of stimuli, along with (4)initial validation of the rAET.

Method

A hierarchy of common alcoholic beverages was established, along with a consensus regarding beverage presentation format.A professional artist iteratively developed pictographs of characters exhibiting different emotions in everyday scenarios and specialised photography of beverages was undertaken. Accurate identification/recognition of these stimuli was then established using a response box, whereby participants indicated which word (from eight) matched the onscreen images presented.Finally, developed stimuli were included within the rAET.

Results

Informing stimuli development and selection, wine, beer and vodka were the most common alcoholic beverages that participants reported consuming, with a preference for photographic representations.Inverse efficiency scores (based on accuracy and reaction time) suggested some variability in the recognition of certain beverage types and emotional stimuli, highlighting which stimuli may be best for inclusion in the rAET. Confirmatory factorial analyses of rAET responses suggests it has good construct validity.

Conclusion

Maximising the transparency of stimuli selection, development and assessment provides a solid basis for systematic and valid scenario-based assessments of alcohol-related beliefs.

使用象形表示评估与酒精相关的信念：开发和验证修订后的酒精预期任务的系统方法

摘要

目标

为了系统地开发和测试包含在修订后的酒精期望任务 (rAET) 中的刺激 - 一种对酒精相关信念的象形评估。本文使用英国成人定期社交饮酒者样本，记录了 (1) 选择 (2) 开发和(3) 刺激测试，以及 (4) rAET 的初始验证。

方法

建立了常见酒精饮料的层次结构，以及对饮料呈现形式的共识。专业艺术家迭代开发了在日常场景中表现出不同情绪的人物象形文字，并进行了专门的饮料摄影。然后使用响应框建立对这些刺激的准确识别/识别，参与者指出哪个单词（来自八个）与呈现的屏幕图像匹配。最后，开发的刺激包含在 rAET 中。

结果

告知刺激的发展和选择，葡萄酒、啤酒和伏特加是参与者报告消费的最常见的酒精饮料，他们更喜欢摄影表现。反向效率得分（基于准确性和反应时间）表明在识别某些饮料类型方面存在一些差异和情绪刺激，强调哪些刺激可能最适合纳入 rAET。对 rAET 反应的验证性因子分析表明它具有良好的结构效度。

结论

最大限度地提高刺激选择、开发和评估的透明度，为系统和有效的基于情景的酒精相关信念评估提供了坚实的基础。
