Three theories attempt to explain the racial disparities in arrest between White and Black Americans: Differential Involvement Hypothesis, Differential Selection and Processing Hypothesis, and Social Disorganization Theory. We tested these hypotheses simultaneously in a multiple-group longitudinal panel model with the ADD Health dataset (Black n = 2459, White n = 7403). After controlling for contextual and behavioral factors, we still found Black young adults were arrested seven times more often than their White counterparts. To maintain cultural competence, it is imperative for clinicians to be aware of these disparities when working with families of different races in order to adjust treatment accordingly, but advocacy for greater systemic change may be more important for some communities than therapy alone.
