Most attempts to quit smoking end in failure, with many quitters relapsing in the first few days. Responses to smoking-related cues may precipitate relapse. A modified emotional Stroop taskwhich measures the extent to which smoking-related words disrupt performance on a reaction time (RT) task-was used to index the distracting effects of smoking-related cues. Smokers (N = 158) randomized to a high-dose nicotine patch (35 mg) or placebo patch completed the Stroop task on the 1st day of a quit attempt. Smokers using an active patch exhibited less attentional bias, making fewer errors on smoking-related words. Smokers who showed greater attentional bias (slowed RT on the first block of smoking words) were significantly more likely to lapse in the short-term, even when controlling for self-reported urges at the test session. Attentional bias measures may tap an important component of dependence.Keywords attentional bias; emotional Stroop; relapse; smoking cessation Most attempts to quit smoking end in failure. Less than 5% of smokers trying to quit on their own maintain abstinence for 12 months (Hughes et al., 1992;Ward, Klesges, Zbikowski, Bliss, & Garvey, 1997). In smoking-cessation clinics, typically only 20-25% of smokers are abstinent at 6 months, and fewer are abstinent at 12 months. Relapse to smoking is rapid as well as common, with many relapses occurring in the first few days (Garvey, Bliss, Hitchcock, Heinold, & Rosner, 1992;Hughes et al., 1992). Medications such as nicotine replacement and bupropion improve outcomes (Jorenby et al., 1999; Silagy, Mant, Fowler, & Lancaster, 2000), but even with treatment, the majority of cessation efforts end in failure. Therefore, it is important to understand the psychological processes that cause the rapid relapse to smoking in the first few days, so that more effective relapse-prevention interventions can be developed.It is unclear what psychological processes underlie early lapses to smoking. Nicotine withdrawal in acute abstinence has been suggested as a critical process enhancing motivation to smoke and lapses to smoking, but it has been hard to demonstrate a strong link between severity of withdrawal and outcome in smoking cessation (Hughes, Higgins, & Hatsukami, 1990;Patten & Martin 1996). Many theories of drug addiction assume that responses to drugrelated cues are critical in maintaining drug use (e.g., Niaura et al., 1988;Robinson & Berridge, 1993;Siegel, 1983;Stewart, de Wit, & Eikelbloom, 1984;Wikler, 1948). Research on the details of initial lapse episodes (e.g., Shiffman, Paty, Gnys, Kassel, & Hickcox, 1996) suggests that environmental stimuli and events play a substantial role in precipitating initial lapses, and when such a lapse occurs, complete relapse is nearly certain to follow: 85-90% of lapses lead
