Structural equation model (SEM) predicting general COVID-19 concerns, COVID-19 vaccine accessibility, COVID-19 vaccine concerns, and trust in public health agencies using demographic characteristics and racism experience. The shared variance (r2) between indicators formed the latent variable: vaccine accessibility = 0.08; vaccine concerns = 0.14; and racism = 0.30. These statistics indicate the association and hence internal consistency among the items [30].
