We examined cultural differences in the item characteristic functions of self-reported of symptoms of depression, anxiety, and mania-hypomania in a Latino population taking Computerized Adaptive Tests for Mental Health (CAT-MH) in Spanish versus a non-Latino sample taking the tests in English. We studied differential item functioning (DIF) of the most common adaptively administered symptom items out of a bank of 1,008 items between Latino (n = 1276) and non-Latino (n = 798) subjects. For depression, we identified 4 items with DIF that were good discriminators for non-Latinos but poor discriminators for Latinos. These items were related to cheerfulness, life satisfaction, concentration, and fatigue. The correlation between the original calibration and a Latino-only new calibration after eliminating these items was r = .990. For anxiety, no items with DIF were identified. The correlation between the original and new calibrations was r = .993. For mania-hypomania, we identified 4 items with differential item functioning that were good discriminators for non-Latinos but poor discriminators for Latinos. These items were related to risk-taking, self-assurance, and sexual activity. The correlation between the original and new calibration was r = .962. Once the identified items were removed, the correlation between the original calibration and a Latino-only calibration was r = .96 or greater. These findings reveal that the CAT-MH can be reliably used to measure depression, anxiety, and mania in Latinos taking these tests in Spanish.

我们研究了在接受西班牙语计算机化自适应测试（CAT-MH）的拉丁裔人群与接受英语测试的非拉丁裔人群中，自我报告的抑郁、焦虑和躁狂-轻躁狂症状的项目特征函数中的文化差异。我们研究了最常见的适应症状项目的差异项目功能（DIF），这些项目是从 1008 个项目中得出的，包括拉丁裔（n = 1276）和非拉丁裔（n = 798）患者。对于抑郁，我们确定了 4 项具有 DIF 的项目，这些项目对非拉丁裔患者是良好的鉴别器，但对拉丁裔患者是较差的鉴别器。这些项目与愉快、生活满意度、注意力和疲劳有关。消除这些项目后的原始校准和拉丁裔独有的新校准之间的相关性为 r =.990。对于焦虑，没有发现具有 DIF 的项目。原始校准和新校准之间的相关性为 r =.993。对于躁狂-轻躁狂，我们确定了 4 项具有差异项目功能的项目，这些项目对非拉丁裔患者是良好的鉴别器，但对拉丁裔患者是较差的鉴别器。这些项目与冒险、自信和性行为有关。原始和新校准之间的相关性为 r =.962。一旦去除了确定的项目，原始校准和拉丁裔患者独有的校准之间的相关性为 r =.96 或更高。这些发现表明，CAT-MH 可以可靠地用于测量接受西班牙语测试的拉丁裔人群的抑郁、焦虑和躁狂。（PsycINFO 数据库记录（c）2018 APA，保留所有权利）。
