Exploratory Factor Analysis and Psychometric Properties of the Sexual Coercion Inventory.

The purpose of the present study was to examine the psychometric properties of the Sexual Coercion Inventory (SCI; Waldner, Vaden-Goad, & Sikka, 1999), revised by the authors (SCI-R). Overall, 514 high school and college students from a Midwestern state completed the SCI-R. To complete the SCI-R, high school participants completed paper-pencil surveys with those younger than 18 obtaining parental consent; college students older than 18 completed computer-based and paper-pencil surveys. Exploratory factor analysis and reliability analyses were conducted to examine the validity of score interpretation and reliability of scores for the measure. Results suggested that a 13-item multidimensional measure consisting of two factors, Manipulation and Substance Use and Aggression, provided the best parsimony and theoretical fit. Examination of convergent and discriminant validity of scores provided additional psychometric support for the revised SCI-R, specifically pertaining to other measures of sexual victimization. The SCI-R may be a useful tool for researchers to explore manipulation tactics in more depth while also assessing and differentiating between victimization that meets legal definitions of rape and non-criminal sexual victimization.
