race/ethnicity as well as distinctions between developmentally normative changes and pathological symptoms related to tolerance and time spent. As indicated by other investigators (Langenbucher et al., 2004; Martin et al., 2006; Saha et al., 2006), future research should continue to examine the dimensional properties of these symptom criteria to inform future DSM diagnostic conceptualizations. Applications of newer hybrid models (Muthén, 2006), which include both categorical and dimensional representations and external validating criteria, can provide clearer boundary estimates for proposed DSM-V diagnosis and more precise prevalence estimates for AUD among adolescents and adults.
