Use of the Heterosexist Harassment, Rejection, and Discrimination Scale With Different Sexual Orientation, Gender, and Racial/Ethnic Groups: An Examination of Measurement Invariance

The Heterosexist Harassment, Rejection, and Discrimination Scale (HHRDS) is one of the most commonly used measures of sexual orientation-related discrimination, but little is known about its psychometric properties across different sexual orientations, gender, and racial/ethnic groups. A three-factor model was initially obtained, but most studies treat the HHRDS unidimensionally. Therefore, we tested whether the HHRDS exhibited measurement invariance across sexual orientation, gender, and racial/ethnic groups among 792 sexual minority young adults (aged 18–29) who participated in an online study. Across models, the three-factor solution fit better than the one-factor solution. All models achieved configural invariance and most achieved metric invariance; none of the considered models achieved scalar invariance (1–3 items were not equivalent across groups, depending on the comparison). Findings suggest that the HHRDS generally functions equivalently across sexual orientation, gender, and racial/ethnic groups, but some caution in interpreting scores is warranted.
