对自杀行为的科学和临床工作的一个长期挑战是，人们往往有动机否认或隐瞒自杀想法。我们提出，考虑自杀的人会对自杀相关刺激具有客观可测量的注意力偏差，这种偏差可以预测未来的自杀行为。参与者是124名到精神病急诊科就诊的成年人，他们接受了改良的情绪Stroop任务，并随访了6个月。相对于中性词语，自杀未遂者对与自杀相关的词语表现出注意力偏见，并且这种偏见在最近尝试过的人中最为强烈。重要的是，这种自杀特异性注意力偏差预测了哪些人在接下来的六个月内有自杀企图，超过了其他临床预测因素。对更一般的负价词的注意偏向并不能预测任何与自杀相关的结果，这支持了所观察到的效应的特异性。这些结果表明，自杀特异性注意力偏差可以作为自杀风险的行为标记，并最终改善自杀相关结果的科学和临床工作。
A long-standing challenge for scientific and clinical work on suicidal behavior is that people often are motivated to deny or conceal suicidal thoughts. We proposed that people considering suicide would possess an objectively measurable attentional bias toward suicide-related stimuli, and that this bias would predict future suicidal behavior. Participants were 124 adults presenting to a psychiatric emergency department who were administered a modified emotional Stroop task and followed for six months. Suicide attempters showed an attentional bias toward suicide-related words relative to neutral words, and this bias was strongest among those who had made a more recent attempt. Importantly, this suicide-specific attentional bias predicted which people made a suicide attempt over the next six months, above and beyond other clinical predictors. Attentional bias toward more general negatively-valenced words did not predict any suicide-related outcomes, supporting the specificity of the observed effect. These results suggest that suicide-specific attentional bias can serve as a behavioral marker for suicidal risk, and ultimately improve scientific and clinical work on suicide-related outcomes.
