A Psychometric Investigation of the Hate-Motivated Behavior Checklist.

Hate-motivated behavior (HMB) comprises a continuum ranging from microaggressions to criminal acts. The measurement of HMB is limited primarily to one or two minoritized groups in any given instrument. Current HMB research also lacks a way to assess the full range of acts and motivations for bias-based behavior.

The HMBC is a self-report instrument of HMB perpetration; the instrument also has sections capturing victim target group (e.g. race, sexual orientation, disability) and perpetrator motivation for HMB commission (e.g., perceived threat, impulsivity). We conducted an online cross-sectional survey of community-dwelling adults and college students (
