Abstract
Abstract: The present research tested the dimensionality and cross-cultural differential item functioning of the Short Dark Tetrad (SD4; Paulhus et al., 2021 ) in samples of university students (total N = 804) from Italy ( N = 268), Romania ( N = 313), and the United Kingdom ( N = 223), respectively. Multidimensional Item Response Theory was used to model the data and ordinal logistic regression for differential item functioning analyses. The results showed that a four-factor model was the best fit for the data. However, the model showed metric non-invariance between the three samples, as well as non-negligible differential item functioning for several items in each of the four factors, in line with findings from previous research on cultural differences in antagonistic traits. Implications for theory and research are discussed.
摘要：本研究分别在来自意大利（N=268）、罗马尼亚（N=313）和英国（N=223）的大学生（总人数N=804）样本中测试了短暗四元组（SD4；Paulhus et al.，2021）的维度和跨文化差异项目功能。多维项目反应理论用于数据建模，有序逻辑回归用于差异项目功能分析。结果表明，四因素模型最适合数据。然而，该模型显示了三个样本之间的度量非不变性，以及四个因素中每个因素中几个项目的不可忽略的差异项目功能，这与之前关于拮抗性状文化差异的研究结果一致。讨论了对理论和研究的启示。
期刊介绍：
The main purpose of the EJPA is to present important articles which provide seminal information on both theoretical and applied developments in this field. Articles reporting the construction of new measures or an advancement of an existing measure are given priority. The journal is directed to practitioners as well as to academicians: The conviction of its editors is that the discipline of psychological assessment should, necessarily and firmly, be attached to the roots of psychological science, while going deeply into all the consequences of its applied, practice-oriented development.
