title: Induction of smoking urge through imaginal and in vivo procedures: physiological and self-report manifestations.
abstract: This experiment assessed reactivity to imaginal and in vivo smoking and control cues. One hundred current smokers were assessed during 2 sessions separated by a 6-hr interval, and half of the participants were abstinent from smoking over this interval. Verbal and physiological reactivity measures were selected based on their relevance for several models of urge. Results indicated that imaginal and in vivo smoking cues were equally effective at eliciting high levels of self-reported urges. Smoking deprivation led to a general enhancement in urge report, rather than a specific increase to smoking cues. Physiological responding differed somewhat as a function of urge induction method, although autonomic responses to smoking cues were uniformly consistent with the direct effects of nicotine. There was no relationship between verbal and physiological urge indices. Implications of the findings for several contemporary models of drug urges are discussed.
