We examine differences on the Self-Injury Implicit Association Test (SI-IAT) by history of non-suicidal self-injury (NSSI), in a test-retest design, to examine short-term temporal stability of SI-IAT scores.
Treatment-seeking participants ( = 113; 58% female; 89% White; = 30.57) completed the SI-IAT and self-report measures at two time points ( = 3.8 days).
Data suggested NSSI (51% of the sample endorsed lifetime NSSI) was related to Time 1 (T1) identity and attitude, and affected stability of scores. T1 and T2 SI-IAT identity and attitude were more strongly related for participants with NSSI history. NSSI characteristics (recency; number of methods) affected stability.
The short-term test-retest reliability of the SI-IAT is strong among those with NSSI history from T1 to T2. However, the SI-IATs use with participants without a history of NSSI was not supported beyond its established ability to differentiate between groups by NSSI history. This test may provide clinically-relevant assessment among those with a history of NSSI.
我们通过非自杀性自伤（NSSI）的历史，在测试-重测设计中检查自我伤害内隐联想测验（SI-IAT）的差异，以检验 SI-IAT 分数的短期时间稳定性。
治疗性寻求参与者（ = 113; 58%为女性；89%为白人；平均年龄为 30.57 岁）在两个时间点（ = 3.8 天）完成了 SI-IAT 和自我报告测量。
数据表明，NSSI（样本中有 51%的人有过终生 NSSI）与 T1 的身份和态度有关，并影响了分数的稳定性。有 NSSI 病史的参与者，T1 和 T2 的 SI-IAT 身份和态度相关性更强。NSSI 的特征（近期；方法的数量）影响了稳定性。
在 T1 到 T2 期间，有 NSSI 病史的参与者中，SI-IAT 的短期重测信度很强。然而，对于没有 NSSI 病史的参与者，SI-IAT 的使用并不能超出其通过 NSSI 病史区分群体的既定能力。该测试可能为有 NSSI 病史的人提供临床相关的评估。
