Objective
To compare the efficacy of Mindfulness-Based Addiction Treatment (MBAT) to a Cognitive Behavioral Treatment (CBT) that matched MBAT on treatment contact time, and a Usual Care (UC) condition that comprised brief individual counseling.
Method
Participants (N=412) were 48.2% African-American, 41.5% non-Latino White, 5.4% Latino and 4.9% other, and 57.6% reported a total annual household income < $30,000. The majority of participants were female (54.9%). Mean cigarettes per day was 19.9 (SD= 10.1). Following the baseline visit, participants were randomized to UC (n = 103), CBT (n = 155), or MBAT (n = 154). All participants were given self-help materials and nicotine patch therapy. CBT and MBAT groups received eight two-hour in person group counseling sessions. UC participants received four brief individual counseling sessions. Biochemically verified smoking abstinence was assessed 4 and 26 weeks after the quit date.
Results
Logistic random effects model analyses over time indicated no overall significant treatment effects, (completers only: F(2,236) = 0.29, p=.749; intent-to-treat: F(2,401) = 0.9, p=.407). Among participants classified as smoking at the last treatment session, analyses examining the recovery of abstinence revealed a significant overall treatment effect, F(2,103)=4.41, p=.015 (MBAT vs. CBT: OR=4.94, 95% CI: 1.47 to 16.59, p=.010, Effect Size =.88; MBAT vs. UC: OR=4.18, 95% CI: 1.04 to 16.75, p=.043, Effect Size =.79).
Conclusions
Although there were no overall significant effects of treatment on abstinence, MBAT may be more effective than CBT or UC in promoting recovery from lapses.
