A previous study by Nock et al. (2010) suggested that people’s implicit identification with “death” or “suicide” can accurately predict whether they will attempt suicide several months in advance. We report the first direct and independent replication of this promising finding. Participants were 165 patients seeking treatment at a psychiatric unit in France. At baseline, patients completed the Suicide–Implicit Association Test (S–IAT), a semistructured interview, and a self-report measure of suicide ideation. Six months later, we contacted participants by phone and examined their hospital medical records to determine whether they had made a new suicide attempt. Results showed that the S–IAT did not distinguish between patients who were admitted to the hospital following suicide attempts and those who were admitted for other reasons. As in the original study, however, the S–IAT predicted suicide attempts within the 6-month follow-up period beyond well-known predictors. The test correctly classified 85% of patients (95% confidence interval = [76.91, 91.53]), supporting its diagnostic value for identifying who will make a suicide attempt.

预测一个致命的决定：直接复制自杀-内隐关联测试的预测有效性

Nock 等人之前的一项研究。(2010) 提出，人们对“死亡”或“自杀”的内隐认同可以准确预测他们是否会提前几个月尝试自杀。我们报告了这一有希望的发现的第一次直接和独立的复制。参与者是 165 名在法国精神病院寻求治疗的患者。在基线时，患者完成了自杀-内隐联想测试 (S-IAT)、半结构化访谈和自杀意念的自我报告测量。六个月后，我们通过电话联系了参与者并检查了他们的医院医疗记录，以确定他们是否再次尝试自杀。结果表明，S-IAT 没有区分因企图自杀而入院的患者和因其他原因入院的患者。然而，与最初的研究一样，S-IAT 预测的 6 个月随访期内的自杀企图超出了众所周知的预测因素。该测试正确分类了 85% 的患者（95% 置信区间 = [76.91, 91.53]），支持其识别谁将尝试自杀的诊断价值。
