Validation of the Outcome Expectancy Scale for HIV Serostatus Disclosure to Female Sex Partners Among Men Who Have Sex with Men and Women Living with HIV in China

摘要

The study aimed to develop an instrument, Outcome Expectancy Scale (OES), to assess outcome expectancies regarding disclosing HIV-positive status to the regular female sex partner (i.e. girlfriend, wife) based on a cross-sectional survey among 217 men who have sex with men and women living with HIV. We developed the positive OES and negative OES, and five factors were identified for each of them by the Exploratory Factor Analysis, respectively. The psychometric properties were satisfactory. This 30-item OES was valid and reliable in assessing outcome expectancies, and it could be used to inform intervention design and theory development.
