The psychometric properties of the Ukrainian version of the revised Sociosexual Orientation questionnaire (SOI-R)

This study aimed to evaluate the psychometric properties of the Revised Sociosexual Orientation Inventory (SOI-R) in a Ukrainian sample. A sample of 469 adults aged 18–60 years (M = 27.8, SD = 8.9, 20% males) completed Q&A form on sociodemographic data, Ukrainian translation of the SOI-R, measures of personality organization, and meanings of sexual behavior. A three-factor original model with correlated latent variables showed a good fit to the Ukrainian data: χ2 = 60.7, p < 0.001, χ2/df=2.5, NFI=0.962, CFI=0.976, TLI=0.964, GFI=0.970, SRMR=0.059, RMSEA=0.06. Cronbach’s α for internal consistency was high (0.77–0.86 for total score and subscales). Convergent validity was established by significant positive correlations of SOI-R subscales with personality diffuseness and meanings of sexual behavior related to satisfaction of personal needs. In line with prior research, this study revealed that unrestricted sociosexuality was more characteristic of men, younger individuals, singles, and those with lower levels of formal education. The results suggest that the Ukrainian version of the SOI-R scale is a reliable and valid measure of sociosexual orientation, accurately measuring the diversity of this important aspect of human sexual behavior.
