Abstract

Sociosexuality refers to the propensity to engage in sexual relations without closeness or commitment, varying from a restricted to an unrestricted orientation. The aim of this research was to scrutinise the psychometric properties of a Portuguese version of the revised Sociosexual Orientation Inventory (SOI-R; Penke & Asendorpf, 2008). The study included 549 persons (50% women) aged 18–75 years (M = 38.73; SD = 17.77). The psychometric properties of the SOI-R were analysed by means of confirmatory factor analysis, internal consistency, and validity. Confirmatory factor analysis showed the expected three-factor structure of the measure. The SOI-R presented adequate internal consistency. Women were less unrestricted than men in all facets of sociosexuality. This Portuguese version of the SOI-R seems to be reliable and valid for evaluating sociosexuality in a Portuguese-speaking population, and can be utilised for experimental and applied works. The significance and limitations of the results are discussed.
