Two-Dimensional Structure of the Sociosexual Orientation Inventory and Its Personality Correlates

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.

Height and jealousy over partner’s ex and a new rival among coupled men and women

Recent studies suggest that body height has an effect on the intensity of jealousy among men and women. Since short men and both short and tall women are regarded as less attractive, they could be at greater risk of being cheated by their partners and therefore more jealous. Numerous studies have documented sex differences in jealousy about a partner’s sexual and emotional infidelity with a person of the opposite sex. However, the partner’s ex as a rival has been neglected in the literature. Therefore, in this study the relationships between height and jealousy about two types of infidelity among 112 heterosexual men and 314 women were investigated. Infidelity scenarios included two types of rival: new rival and partner’s ex. As expected on the basis of prior studies, men were more jealous of sexual infidelity and women of emotional infidelity. Both sexes reported greater jealousy over a new rival than over partner’s ex. Among men, there were no relationships between height and jealousy, while among women...
