Figure 3 shows the mediational model in which current demographic advantage, current mother/father mental health, current deviance, and current alcohol use were tested as mediators of the association between family density of alcoholism and child behavior. The fit of the model was good: χ2(89)=163.59, p=.00, CFI=.98, RMSEA=.04. With the exception of one marginally significant association (density to father mental health, β=.11, p=.05), density was significantly associated with all of the proposed mediators, one of the requirements of a mediational model (MacKinnon et al., 2002). All but two of the proposed mediators (mother alcohol, father deviance) were associated with one or both of the dependent measures, another requirement of mediation. With these mediators included, the effect of family density diminished to nonsignificance for both BD (β=−.04, p=.45) and CP (β=−.01, p=.92). Model-produced intercorrelations among the mediators are displayed in Table 1. Table 2 shows the total effects disaggregated into direct and indirect effects. All associations between density and child behavior were mediated by current parent functioning with no direct effects of density on child behavior remaining.
