Financial behavioral health (FBH) influences numerous socio-ecological domains, affecting investment risk willingness and consequent wealth levels. The experience of FBH by racial group is unknown, and findings of differences between Black and White investors’ risk willingness are mixed. The study’s aims are to establish an FBH measure and explore its application to risk willingness by racial group. The study used a subset of data from FINRA’s 2018 National Financial Capability Study, including Black (n= 2835) and White (n= 21,289) respondents. Through factor analysis, 19 items were confirmed for the FBH measure; the measure was then applied to investment risk willingness using structural equation modeling (SEM). Invariance analyses showed that the FBH model had an excellent fit for White respondents but not Black respondents. The SEM analysis determined that FBH accounted for 37% of the variance in risk willingness (R2= 0.368; β = 0.256,p< 0.001). Racial group affiliation was a negligible predictor of risk willingness (β = −0.084,p< 0.001). This project contributes an empirical basis for FBH, emphasizes the importance of FBH for investment risk willingness, and elucidates that racial group differences in risk willingness could be an unlikely contributor to the wealth gap.
