Factor Structure of Leigh’s (1990) Alcohol Sex Expectancies Scale in Individuals in Treatment for HIV Disease
AIDS and Behavior Published online 15 September 2008


The purpose of this study was to validate the use of Leigh’s (1990) alcohol sex expectancies scale among HIV-infected individuals presenting for treatment as a way to facilitate research on sexual risk reduction among individuals in that population.

A principal components factor analysis with oblique rotation of the original 13-item Leigh scale within each HIV group in Sample 1 revealed a 2-factor (7 and 4 items, respectively) solution that was consistent across both HIV groups. These factors were named “More Open to Sexual Pleasure” (Factor 1) and “Reduced Inhibitions about Sex (Factor 2).” A confirmatory factor analysis of the 11-item, 2-factor solution on the full Sample 2 showed a modest fit to the data, excellent internal consistency reliability of both factors, a high correlation between the factors, and strong evidence for construct validity.

These results were interpreted as supporting the use of the 11-item, 2-factor version of Leigh’s scale in studies of clinical samples of HIV-positive adults, and directions for research on further scale refinement are discussed.
