In an article in a forthcoming special issue of Nicotine and Tobacco Research, a team of Methodology Center scientists examines the changing relationships between factors that predict relapse for smokers who are quitting. The researchers, led by Research Associate Sara Vasilenko, used time-varying effect models to analyze ecological momentary assessment data and found that predictors of relapse changed over the two weeks post quit. Cigarette cravings significantly predicted relapse throughout the two weeks. However, baseline dependence was significant early in the quit process but was unimportant after one week. Conversely, negative mood became a stronger predictor of relapse as time progressed.
