创伤后应激障碍（PTSD）与严重损害和生活质量下降有关。情绪斯特鲁普任务（EST）一直是阐明创伤后应激障碍的一些核心缺陷的一种手段，但这方面的文献仍然不一致。我们对创伤后应激障碍人群的EST研究进行了荟萃分析，以综合这一研究体系。26项研究包括538名PTSD参与者，254名非创伤暴露对照组（NTC）和276名创伤暴露对照组（TC）。PTSD组与TC组相比，PTSD相关词对EST表现的影响更大。PTSD组与TC组无显著差异。在测试被试效应量时，PTSD组中PTSD相关词和一般威胁性词相对于中性词对EST表现有损害，而PTSD组中只有PTSD相关词对EST表现有损害。这些模式在NTC组中没有发现。调节分析表明，与随机设计相比，这些效应在封闭设计中显著大于随机设计，在暴露于攻击性创伤的样本中显著大于暴露于非攻击性创伤的样本。讨论了理论和临床意义。
Posttraumatic stress disorder (PTSD) is associated with significant impairment and lowered quality of life. The emotional Stroop task (EST) has been one means of elucidating some of the core deficits in PTSD, but this literature has remained inconsistent. We conducted a meta-analysis of EST studies in PTSD populations in order to synthesize this body of research. Twenty-six studies were included with 538 PTSD participants, 254 non-trauma exposed control participants (NTC), and 276 trauma exposed control participants (TC). PTSD-relevant words impaired EST performance more among PTSD groups and TC groups compared to NTC groups. PTSD groups and TC groups did not differ. When examining within-subject effect sizes, PTSD-relevant words and generally threatening words impaired EST performance relative to neutral words among PTSD groups, and only PTSD-relevant words impaired performance among the TC groups. These patterns were not found among the NTC groups. Moderator analyses suggested that these effects were significantly greater in blocked designs compared to randomized designs, towards unmasked compared to masked stimuli, and among samples exposed to assaultive traumas compared to samples exposed to non-assaultive traumas. Theoretical and clinical implications are discussed.
