Descriptive statistics are presented in Table 2 to highlight differences across the latent classes. Respondents in the high comorbidity class had a similar number of internalizing conditions as individuals in the internalizing comorbidity class (3.1 versus 2.6, respectively), but they had twice as many externalizing conditions than individuals in the externalizing comorbidity class (2.2 versus 1.1, respectively). The high comorbidity class was overrepresented by females, whereas the externalizing class was overrepresented by males. As compared to the no comorbidity class, the classes with comorbidity (and particularly the high comorbidity class) had elevated levels of AUD severity. The proportion of those who received prior treatment was the highest in the high comorbidity class (54%) and lowest in the comorbidity unaffected class (13%).
