This study evaluated the validity and reliability of a modified version of the Schedule of Sexist Events-Lifetime (SSE, Klonoff & Landrine, 1995) (SSE-LM) and its applicability to women's HIV risk behaviors. Participants included a multi-ethnic baseline sample of women (N = 754) between the ages of 18 and 39 years (M = 22.43) who attended family planning clinics in the San Francisco Bay area. Confirmatory factor analysis demonstrated that a higher-order factor model provided a satisfactory and a more parsimonious account for correlations among the measure's four sexism factors than a single latent factor model. Scale reliability for the SSE-LM was excellent (Cronbach' s alpha = .89). Structural equation modeling results demonstrated that the SSE-LM is associated with women's sexual risk behaviors with secondary partners, but not primary partners.
