Abstract

[Correction Notice: An erratum for this article was reported in Vol 77(2) of Journal of Consulting and Clinical Psychology (see record 2009-03774-013). There are two errors in the means and standard deviations reported in Table 1 (p. 561). The mean (and standard deviation) for the Total sample % positive urine drug tests (28 days) in the motivational enhancement therapy (MET) column is not 0.21 (SD = 0.35) as reported, but rather 0.28 (SD = 0.40). The mean (and standard deviation) for the Total sample % positive urine drug tests (28 days) in the counseling as usual (CAU) column is not 0.28 (SD = 0.40) as reported, but rather 0.31 (SD = 0.41). These corrections do not change any of the values reported for the d, F, or p statistics in this table.] The effectiveness of motivational enhancement therapy (MET) in comparison with counseling as usual (CAU) for increasing retention and reducing substance use was evaluated in a multisite randomized clinical trial. Participants were 461 outpatients treated by 31 therapists within 1 of 5 outpatient substance abuse programs. There were no retention differences between the 2 brief intervention conditions. Although both 3-session interventions resulted in reductions in substance use during the 4-week therapy phase, MET resulted in sustained reductions during the subsequent 12 weeks whereas CAU was associated with significant increases in substance use over this follow-up period. This finding was complicated by program site main effects and higher level interactions. MET resulted in more sustained substance use reductions than CAU among primary alcohol users, but no difference was found for primary drug users. An independent evaluation of session audiotapes indicated that MET and CAU were highly and comparably discriminable across sites.
