Measuring Aspects of Multisexuality: Initial Development of the Multisexual Identity Scale

Abstract

This article outlines the development of a novel scale for assessing identity aspects of multisexual individuals. To establish the factor structure and assess the reliability and validity of the Multisexual Identity Scale (MIS), three studies in Greece were conducted. The first Study (N = 109) provided data for exploratory factor analysis. The proposed factor structure underwent confirmatory factor analysis in the second Study (N = 107), yielding a 6-factor solution with 22 items. These six subscales addressed Identity Intersection/Holistic Growth, Label Rejection, LGBTQIA2+ Community Involvement, Heterosexual Community Involvement, Rejection of Monosexual Identity, and Understanding Multisexual Identity. The third Study (N = 109) further assessed reliability and validity, including a measurement invariance test based on sex assigned at birth. Overall, the results support the adoption of this newly developed scale, offering valuable insights into multisexual identity with satisfactory psychometric outcomes. Limitations are also discussed.
