Table 2.
Prevalence rates in counts and percentage (in parentheses) for the diagnoses of externalizing disorders (EXT) in LR and HR groups in the total sample and within gender. Note that the HR group had higher prevalence rates in all the diagnoses than the LR group. Significance levels based on Chi-square test have been marked with asterisks (in HR columns). Diagnosis of SUD is based on DSM-IV criteria for dependence or abuse. Empty cell (with a dash) represents the count of zero.
