Relapse prevention versus broad spectrum treatment for smoking cessation: a comparison of efficacy

Abstract

The efficacy of a smoking cessation relapse prevention (RP) program, emphasizing cognitive-behavioral coping skills, was compared to that of a broad spectrum (BS) program, which emphasized behavioral skills. It was hypothesized that the RP program would be more effective in producing long-term abstinence, compared to the BS package. Abstinence rates validated by saliva thiocyanate and carbon monoxide, as well as self-report of smoking reduction, were measured at posttreatment, 3 and 6 months. No differences in posttreatment quit rates were found between the two groups, although both programs produced significantly higher quit rates than the wait-list control group. Contrary to prediction, the BS group produced marginally significantly greater abstinence at 3 months. No differences in abstinence were found at 6 months. Reduction in cigarette consumption was marginally significantly greater for the BS group at 3 and 6 months. Various mediators of treatment outcome were not found to influence success in quitting. There was a significant weight gain in those who quit.
