Abstract

Objective

This study examined two Death-Implicit Association Test versions targeting associations between the self-concept (standard identity D-IAT; iD-IAT) and internal versus external control (adapted control D-IAT; cD-IAT) and death among suicide attempters. Additionally, correlations with explicit psychological variables and psychometrics were explored.

Method

116 psychiatric inpatients (58.1 % female; age M = 33.6, SD = 12.4) were classified as single versus multiple and recent versus lifetime suicide attempters. Implicit associations were measured using the iD-IAT and cD-IAT. Self-report measures included constructs relevant to suicidal behaviour.

Results

Recent attempters showed weaker self-life (t(114) = 2.18, p = .016) and internal control-life (t(114) = 2.26, p = .013) associations than lifetime attempters. Multiple attempters exhibited weaker internal control-life associations than single attempters (t(114) = 2.25, p = .007). The iD-IAT correlated with suicidal ideation (r_s(114) = 0.20, p = .032), depression (r_s(114) = 0.20, p = .033) and external control (r_s(114) = 0.21, p = .021), the cD-IAT with suicidal ideation (r_s(114) = 0.25, p = .006) and depression (r_s(114) = 0.26, p = .006). The cD-IAT predicted multiple attempts (χ²(1116) = 3.88, p = .049), showed higher internal consistency (r_sb =. 31, p = .001) and predictive validity in detecting multiple (AUC = 0.64; p = .013) and recent (AUC = 0.62; p = .028) attempters than the iD-IAT.

Conclusions

The cD-IAT shows preliminary potential to differentiate suicidal behaviour based on recency and frequency, offering a tentative step toward understanding cognitive vulnerabilities of at-risk subgroups, warranting further refinement, validation and prospective analyses.

通过内隐认同和控制偏差探索自杀行为：来自死亡-内隐关联测试及其新控制适应的发现

目的探讨两种死亡-内隐联想测验版本在自我概念(标准同一性D-IAT；iD-IAT)和内部与外部对照(适应对照D-IAT；cD-IAT)和自杀未遂者的死亡率。此外，还探讨了显式心理变量和心理测量的相关性。方法116例精神科住院患者(女性58.1%；年龄M = 33.6, SD = 12.4)分为单次与多次、近期与终生自杀企图者。使用iD-IAT和cD-IAT测量内隐关联。自我报告测量包括与自杀行为相关的构念。结果近期尝试者的自我寿命（t(114) = 2.18, p = 0.016）和内部控制寿命（t(114) = 2.26, p = 0.013）的相关性较终身尝试者弱。多重尝试者比单一尝试者表现出较弱的内部控制寿命相关性（t(114) = 2.25, p = .007）。iD-IAT与自杀意念（rs(114) = 0.20, p = 0.032）、抑郁（rs(114) = 0.20, p = 0.033）、外部控制（rs(114) = 0.21, p = 0.021）、cD-IAT与自杀意念（rs(114) = 0.25, p = 0.006）、抑郁（rs(114) = 0.26, p = 0.006）相关。cD-IAT预测多次尝试（χ2(1116) = 3.88, p = 0.049），具有较高的内部一致性(rsb =。31, p = .001)和检测多个的预测效度(AUC = 0.64；p = 0.013)和近期(AUC = 0.62；p = .028)。结论cD-IAT显示了基于近期和频率区分自杀行为的初步潜力，为理解高危亚组的认知脆弱性提供了试试性的一步，需要进一步的改进、验证和前瞻性分析。
