Abstract

Aims Many theories of addiction assume that responses to drug cues maintain drug use and precipitate relapse. There is evidence that measures derived from experimental cognitive psychology yield important information about cue reactivity. We used a pictorial version of the visual probe task to evaluate: (i) whether minimally deprived smokers attend differentially to smoking cues (attentional bias); (ii) whether this bias is related to self-reported craving and dependence; and (iii) whether it predicted outcome in a subsequent cessation attempt.
Design Participants took part in a structured smoking cessation program. Each participant completed the visual probe task roughly 2 weeks before quitting while non-deprived.
Setting A research smoking cessation clinic.
Participants 141 heavy smokers seeking treatment for smoking cessation.
Measurements The computerized attentional bias measure and self-reported urge were taken in a laboratory session. Participants also monitored their smoking and craving on electronic diaries both when smoking ad libitum and for up to 6 weeks post-cessation.
Findings Participants were faster and more accurate in responding to a visual probe that replaced a smoking picture than to a neutral picture, indicating that they showed attentional bias towards the smoking cues. Attentional bias on the first half of the task correlated with pre-task craving, indicating that the bias may tap motivational processes, but it did not predict outcome in smoking cessation.
Conclusions The visual probe task can add useful information about attentional responses to drug cues. Further work is required to uncover the theoretical significance and utility of this measure.
