the millennial and X generations. Rates of ever being diagnosed with a drug dependence were equal across generations. The tetrachoric correlation between help-seeking and treatment utilization was .85 in the full sample. Also in the full sample, the mean age of AUD onset was 21.60 years (standard deviation [SD] = 8.11) with a mean time of 6.16 years (SD = 8.43) to first help-seeking and of 6.12 years (SD = 8.29) to first treatment utilization. For comparison, the mean age for first help-seeking in the full sample was 27.84 years (SD = 9.60) and 27.55 years (SD = 9.44) for first treatment (see Table 2).
