Description
Summary:Sociosexuality refers to individual differences in willingness to engage in casual sex without emotional involvement with the partner. One of the most popular measures of sociosexuality is the Sociosexual Orientation Inventory (SOI) that was initially constructed as a one-dimensional measure. Although a multidimensional approach has been shown to be more informative, one-dimensional SOI scoring is still used. In this article, we replicate previous findings, using confirmatory procedures, that two-dimensional SOI scoring could be more adequate. Further, we demonstrate the advantages of a two-dimensional SOI structure in investigating relationships between sociosexuality and its personality correlates. These results could provide an incentive for a consensus of using multidimensional measures of sociosexuality.
