Many measures, varying in breadth and length, have been constructed to measure narcissism. In recent years, super-short forms have become popular in research settings. Although brief measures hold some advantages, their brevity can come at psychometric costs. Participants recruited from Amazon's Mechanical Turk (N = 473) completed long and brief narcissism measures and criterion measures in a randomized order. Short forms were examined and compared to long forms in terms of their completion times and psychometric properties. Generally, the short forms demonstrated adequate internal consistency, variable convergence with each other, mostly moderate to strong convergence with long forms, and appropriate convergence with external criteria. These findings suggest that some short forms may be used when efficiency of survey administration is particularly important without significant psychometric cost. We discuss the advantages and disadvantages of the brief measures and make recommendations for which to use depending on the priorities of a given study.
许多衡量自恋的方法，在广度和长度上各不相同。近年来，超短形式在研究环境中变得流行。虽然简短的衡量标准具有一些优势，但它们的简洁性可能会带来心理测量上的代价。从亚马逊的 Mechanical Turk 招募的参与者（N=473）按照随机顺序完成了长和短的自恋衡量标准以及标准衡量标准。短形式的完成时间和心理测量特性与长形式进行了检查和比较。一般来说，短形式表现出足够的内部一致性，彼此之间有变化的收敛性，与长形式的收敛性大多为中度到高度，与外部标准的收敛性适当。这些发现表明，在调查管理效率特别重要而没有显著心理测量代价的情况下，可以使用一些短形式。我们讨论了简短衡量标准的优缺点，并根据给定研究的优先事项，提出了使用哪种衡量标准的建议。
