Measurement invariance across diverse groups, though crucial for determining the generalizability of a measure, has not yet been tested in many assessments of suicidal thoughts. The present study assessed the measurement invariance and psychometric properties of one such assessment, the Depressive Symptom Inventory-Suicidality Subscale, across multiple identity dimensions in a large data set (n = 1,118) that combined three diverse samples. Findings supported measurement invariance of the scale by race, ethnicity, and sexual orientation when comparing those who were majority-aligning with their minoritized counterparts, as well as good internal consistency and expected convergent validity. The expected one-factor structure fit well for all three of the samples assessed. Overall, the results support measurement invariance and generalizability of the Depressive Symptom Inventory-Suicidality Subscale. Future studies should continue assessing measures of suicidal thoughts and behaviors through testing invariance across identities, especially as it pertains to specific identity subgroups and their intersections.

测量抑郁症状量表-自杀倾向量表在种族、民族、性取向和少数族裔身份多元化方面的不变性。


不同群体之间的测量不变性虽然对于确定测量的普遍性至关重要，但尚未在许多自杀念头评估中得到检验。本研究评估了一项此类评估的测量不变性和心理测量特性，即抑郁症状量表-自杀性分量表，在结合了三个不同样本的大型数据集 （n = 1,118） 中的多个身份维度上。在比较那些与少数群体一致的人时，研究结果支持按种族、民族和性取向测量量表的不变性，以及良好的内部一致性和预期的收敛效度。预期的单因素结构非常适合所有三个评估的样本。总体而言，结果支持抑郁症状量表-自杀分量表的测量不变性和泛化性。未来的研究应该继续通过测试身份之间的不变性来评估自杀念头和行为的测量，特别是因为它与特定的身份亚群体及其交叉点有关。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
