As seen in Table 1, no main effects for Treatment emerged in the analyses of any of the social network variables tested. Effects for Time, and/or Treatment X Time, were found for: Behavioral Support for Drinking, Behavioral Support for Abstinence, Attitudinal Support for Abstinence, and Number of Abstinent Friends. Examination of least-squares means suggested that Behavioral Support for Drinking decreased significantly in all treatment conditions from baseline to posttreatment, and remained low out to the 27-month follow-up point (results not shown).
