This article describes the development and validation for a measure designed to assess the importance and meaning of Black history-the Scale of Black History Consciousness (SBHC)-in two independently recruited samples of African descent adults. After iterative exploratory (n = 350) and confirmatory (n = 366) factor analytic procedures, a 12-item measure, with scores of two internally consistent factors (sociopolitical beliefs and empowerment beliefs), emerged as the most parsimonious and psychometrically sound. An assessment of scalar measurement invariance using multiple indicators multiple causes modeling indicated that SBHC factors did not differ across racial-ethnic identification or generational status. Validity evidence was established through an examination of bivariate correlations of the SBHC factors with race centrality and impression management. Additionally, participants who endorsed being in environments where learning about Black history was emphasized reported higher SBHC scores than their counterparts who were not exposed to these environments demonstrating known-groups validity. These results provide initial support for the validity and reliability of the SBHC. Findings from this study advance scholarship about the psychological importance of Black history, and the SBHC can contribute to investigations of African descent adults' beliefs about the value of Black history in their lives. Recommendations for further scale development research and practice applications of the SBHC are also discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
