Grant et al. (2004) go on to note that they determined “…the extent to which the addition of these questions might have influenced the comparability of NLAES and NESARC definitions…[by removing them] from the NESARC algorithms used to arrive at abuse and dependence diagnoses, and the associated prevalences were [then] recalculated. Once removed, the NESARC rates of [past-12 month] abuse and dependence decreased by 0.30 and 0.36%” (p. 226).
