Figure 4 shows levels of AA variables over the follow-ups by treatment. AA Involvement increased steadily up to 15 months, but was relatively flat in the NS+CM and CaseM conditions from months 15 to 27 (Figure 4, panel A). The mixed model analysis showed a non-significant main effect for Treatment [F (2, 475) = 2.81; p = .06], a significant Time effect [F (3, 475) = 198.49; p < .001], and a significant Treatment X Time interaction [F (6, 475) = 3.05; p < .01]. Time X Treatment contrasts indicated that the NS condition yielded significantly greater AA Involvement scores from posttreatment through the follow-ups than did the CaseM condition [F (1, 475) = 5.18; p < .05], but the two NS conditions did not differ from one another. The effect size for the NS v. CaseM contrast was moderate, d = .68.
