目的：人们对与物质使用有关的认知偏差越来越感兴趣，但焦虑文献的证据表明，通常用于评估这些偏差的任务可能存在内部可靠性低的问题。我们检查了视觉探针和改良Stroop任务的内部可靠性。设计：视觉探针和改良Stroop任务数据的二次分析，收集了七项独立的研究。设置：人类实验室研究。参与者：健康志愿者（n = 408在七个独立的研究）招募从一般人群的基础上使用酒精或烟草。测量：视觉探头和修改后的Stroop任务措施的物质相关的认知bias.Findings：物质相关的线索的认知偏差的措施，由视觉探头和修改后的Stroop任务，可能是不可靠的。特别是，视觉探测任务表现出较差的内部可靠性，因为没有封闭版本的修改后的Stroop task.Conclusions：修改后的Stroop任务是最好的视觉探测任务作为一种措施的物质相关的认知偏差，其心理测量学特性的基础上。使用认知偏差任务的研究不应该假设它们是可靠的，并且应该在可能的情况下定期报告可靠性估计。(C)2011年由Elsevier爱尔兰有限公司出版。
Aims: There is growing interest in cognitive biases related to substance use, but evidence from the anxiety literature suggests that tasks commonly used to assess these may suffer from low internal reliability. We examined the internal reliability of the visual probe and modified Stroop tasks.Design: Secondary analysis of visual probe and modified Stroop task data collected across seven independent studies.Setting: Human laboratory study.Participants: Healthy volunteers (n = 408 across seven independent studies) recruited from the general population on the basis of alcohol or tobacco use.Measurements: Visual probe and modified Stroop task measures of substance-related cognitive bias.Findings: Measures of cognitive bias for substance-related cues, as assayed by the visual probe and the modified Stroop tasks, may not be reliable. In particular, the visual probe task showed poor internal reliability, as did unblocked versions of the modified Stroop task.Conclusions: The modified Stroop task is preferable to the visual probe task as a measure of substance-related cognitive bias, on the basis of its psychometric properties. Studies using cognitive bias tasks should not assume they are reliable, and should routinely report reliability estimates where possible. (C) 2011 Published by Elsevier Ireland Ltd.
