Even after removing the abuse criteria confounded with DUI, hazardous use and legal problems, the two remaining abuse criteria included in the analysis, role failure and social/interpersonal problems, did contribute to the overall measurement of the criteria in all groups. It is possible that hazardous use and legal problems would show greater discrimination and higher thresholds among individuals without DUIs than those with, since they are much less frequently endorsed by individuals without DUIs. Inclusion of these criteria, however, is not warranted in the current analysis due to their redundancy with DUI status. Had they been included, it is unlikely they would alter the overall conclusion of the analysis.
