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.
