Abstract

Gender data for bupropion suggest that it may be a particularly effective smoking cessation medication for women. It is not known whether the efficacy of this pharmacotherapy differs as a function of the psychotherapy with which it is administered. This study used a two level factorial design to examine the independent and interactive effects of medication (bupropion 300 mg/day vs. placebo) and psychotherapy (cognitive-behavioral therapy [CBT] vs. supportive therapy [ST]). In addition to testing the hypothesis that bupropion with CBT would be most effective of all the treatments, we examined medication compliance and its role in the efficacy of bupropion. Participants were 154 women, aged at least 30 years and smoking more than 10 cigarettes/day. Compliance with study medication was assessed using Medication Event Monitoring Systems (MEMS) over 7 weeks of treatment. Psychological interventions were delivered in 60-min weekly group sessions. Longitudinal analysis of abstinence outcomes from end of treatment (EOT) through 12 months after treatment revealed a significant interaction of medication and therapy. Higher abstinence rates at EOT and 3-, 6-, 9-, and 12-month follow-ups were observed when bupropion was delivered concurrently with CBT (44%, 24%, 30%, 23%, 17%) rather than with ST (18%, 1%, 8%, 5%, 2%). The bupropion-CBT combination, however, was not clearly superior to placebo, regardless of therapy assignment. Higher rates of medication compliance were positively predictive of abstinence, and this effect was most evident in the placebo condition. Findings provide only modest support for CBT as the preferred type of intensive therapy in conjunction with bupropion in women.
