Using self-harm Implicit Association Tests (IATs), we sought to test whether (1) suicidal adolescents show implicit identification with self-harm and whether (2) IATs are reliable and sensitive to psychiatric change and (3) predict future suicide attempts. We administered 6 self-harm IATs to 71 adolescents from a psychiatric inpatient unit and assessed suicidal behaviors at admission, discharge and 3 months after discharge. Results were in the expected direction for each IAT but not statistically significant. After aggregating trials across IATs, suicide attempters showed increased implicit identification with self-harm, compared with non-suicidal controls. IATs showed good reliability and sensitivity to psychiatric change but did not prospectively predict suicide attempts. Adolescent suicide attempters may have stronger implicit associations with self-harm than non-suicidal controls.
我们使用自我伤害内隐联想测验（IAT），旨在测试：（1）自杀青少年是否表现出对自我伤害的内隐认同，以及（2）IAT 是否可靠且对精神状态变化敏感，以及（3）是否可以预测未来的自杀企图。我们对来自精神病住院病房的 71 名青少年进行了 6 项自我伤害 IAT 测试，并在入院、出院和出院后 3 个月评估了自杀行为。每个 IAT 的结果都与预期方向一致，但没有统计学意义。在将 IAT 中的试验进行汇总后，与非自杀对照组相比，尝试自杀者表现出对自我伤害的内隐认同增强。IAT 具有良好的可靠性和对精神状态变化的敏感性，但不能前瞻性地预测自杀企图。青少年自杀企图者可能与非自杀对照组相比，对自我伤害有更强的内隐关联。
