The Sociosexual Orientation Inventory ((SOI-R) ) is a 9-item self-report questionnaire designed to measure individuals differences in the tendency to have casual, uncommitted sexual relationships. This tendency, termed sociosexual orientation is divided into three facets measured by the inventory: ''behavior'' (in terms of number of casual and changing sex partners), ''attitude'' (towards uncommitted sex) and ''desire'' (for people not in a romantic relationship).〔“Beyond global sociosexual orientations: A more differentiated look at sociosexuality and its effects on courtship and romantic relationships” by L. Penke and J. B. Asendorpf, 2008, ‘’Journal of Personality and Social Psychology’’, 95, 1113-1135.〕 The most recent revision is from 2008. ==History== Sociosexuality as a concept was introduced by Alfred Kinsey〔Kinsey, A., Pomeroy, W., & Martin, C. (1948). ‘’Sexual behavior in the human male’’. Philadelphia: Saunders.〕〔Kinsey, A., Pomeroy, W., Martin, C., & Gebhard, E (1953). ‘’Sexual behavior in the human female’’. Philadelphia: Saunders〕 to describe differences in individuals tendency to engage in uncommitted sexual relationships. Minimal research was done until interest in the topic markedly increased when Gangestad and Simpson released their 5-item Sociosexual Orientation Inventory in 1991.〔Simpson, J. A., & Gangestad, S.W. (1991). Individual differences in sociosexuality: Evidence for convergent and discriminant validity. ''Journal of Personality and Social Psychology, 60,'' 870-883.〕 However, serious problems were found with the original scale with respect to sociosexuality as a single dimension, its sometimes low internal consistency, skewed score distribution, and one question inapplicable to singles.〔Webster, G.D., and Bryan, A. (2007). Sociosexual attitudes and behaviors: Why two factors are better than one. ''Journal of Research in Personality'', 41, 917-922〕〔Asendorpf, J.B., and Penke, L. (2005).

Shortcomings of the Sociosexual Orientation Inventory: Can psychometrics inform evolutionary psychology? ''Behavioral and Brain Sciences'', 28, 296-297〕 It was these concerns that led Penke and Asendorpf to create the SOI-R to deal with these issues. There currently exist two variations on the SOI-R currently available in 25 languages, a 9-point response scale for integration with the original Gangestad and Simpson SOI and a 5-point response scale for the majority of subjects. The language versions include Czech,〔Roberts, SC, Klapilová, K, Little, AC, Burriss, RP, Jones, BC, DeBruine, LM Petrie M, Havlíček J. (2012).
