The criterion response curves (CRCs) associated with each model (Figures 1 and 2) were quite similar in terms of the relative severity of DSM-IV cannabis abuse and dependence criteria, with the cannabis quantity-frequency use criterion falling along the least severe end of the cannabis use disorder continuum. In both models, severity was greatest for legal problems, activities given up and neglect of role criteria, lowest for hazardous use and quit/control, with the remaining abuse and dependence criteria representing intermediate levels of severity. There was less variability observed in discrimination, with discrimination values ranging from 1.60 to 1.83 for each of the two models.
