Cross-domain influences on youth risky driving behaviors: A developmental cascade analysis.

We apply a developmental cascade approach to study the longitudinal, cross-domain effects of negative family influence, deviant peer associations, and individual substance use on risky driving among a sample of low-income African American youth. Participants (N = 681) were followed from age 16 to age 21. Using structural equation modeling, we examined conceptual models of pathways to risky driving. Results indicated strong associations between domains within time points among negative family environment, deviant peer associations, individual substance use, and risky driving. Deviant peer associations were related to future risky driving. Alcohol and marijuana use also predicted later deviant peer relationships. The pathways were observed both between age 16 and 18 and between age 18 and 21. Consistent with the cascade hypotheses, we found that risks in one domain manifested as risks in the same domain across time in addition to spreading to other domains.
