Alcohol dependence is clearly part of the externalizing dimension. However, a wide range of studies have shown that alcohol dependence is associated with individual internalizing disorders when these disorders are considered separately [7]. New findings showed that, once the general internalizing psychopathology dimension is accounted for, knowing whether a particular internalizing disorder is present or absent provides little additional information regarding the risk for alcohol dependence. These findings suggest that the components of internalizing psychopathology associated with alcohol dependence are shared and cumulative among common anxiety and depressive disorders [16▪].
