This study has some limitations. As noted in our earlier report (Litt et al., 2007), there was no active coping skills-based treatment against which to compare the NS treatments. Consequently, there is no way to determine if NS is superior to other treatments, such as CBT. The drinking rates reported here, however, are comparable to, or better than, those in other studies reporting long-term outcomes such as Project MATCH, which reported a mean PDA of 69% and 29.4% abstinent at months 37-39 (Project MATCH Research Group, 1998). The high proportion of white participants in our study may limit the generalizability of the findings, however.
