Abstract

Background

Canadian Blood Services (CBS) screens donors based on group status (e.g., men who have sex with men, MSM) instead of specific, high-risk sexual practices (e.g., occurrence of condomless sex). The MSM screening question is embedded in a cluster of questions about stigmatized attributes such as history of imprisonment and illicit substance use. This juxtaposition of the “MSM question” and stigmatized attributes may unintentionally cause blood donors to perceive MSM more negatively. The aim of this research is to determine whether the CBS donor eligibility questionnaire generates negative bias against MSM.

Study Design and Methods

A national, randomized online study of 903 CBS donors was conducted. Participants completed either the existing blood donor eligibility questionnaire or a modified donor questionnaire that repositioned the MSM question among neutral questions. After completing the existing or modified questionnaire, bias against MSM was measured using the sexuality implicit association test (IAT) and Modern Homonegativity Scale – Gay Men (MHS-G). Lastly, participants estimated prevalence rates among MSM of certain stigmatized behaviors.

Results

Participants who completed the existing donor eligibility questionnaire more strongly associated gay men with negative attributes on the IAT (pone-tailed = .045), suggesting question position generated implicit negative bias toward MSM. Responses to the MHS-G (pone-tailed = .506) and prevalence estimation task (p = .443) indicated that question order had no significant impact on explicit bias.

Discussion

Positioning the MSM screening question among stigmatizing questions creates implicit negative bias against MSM. Policy makers should be mindful of question positioning when designing donor questionnaires.
