Exploring Biphobia Among Heterosexuals and LGBTQ + Individuals in Spain: Psychometric Properties of the Biphobia Scale in a Spanish Sample

Abstract

Self-reported questionnaires for assessing biphobia have been developed and validated in English-speaking countries. In Spain, despite considerable rates of biphobia, there is a lack of validated instruments to assess this phenomenon. The aim of this study was to explore the psychometric properties of the Spanish version of the Biphobia Scale (BS), a useful self-reported measure of biphobia. Four hundred and sixty-six participants from the general population in Spain completed the BS, the Ambivalent Sexism Inventory, the Modern Homophobia Scale, and the Internalized Homonegativity Scale. The factorial structure, internal consistency, and convergent validity were analyzed. The results of the factor analysis support a one-factor solution. Cronbach’s alpha and Omega coefficient were .95 and .96, respectively. Evidence of convergent validity was provided, as shown by the significant and positive correlations between biphobia, sexism, homophobia, and internalized homonegativity. The results support the use of the BS in the Spanish population as a valid and reliable measure.
