Clinical correlates of attentional bias to drug cues associated with cocaine dependence.

BACKGROUND AND
OBJECTIVE: Preoccupation (attentional bias) related to drug-related stimuli has been consistently observed for drug-dependent persons with several studies reporting an association of the magnitude of measured attentional bias with treatment outcomes. The major goal of the present study was to determine if pre-treatment attentional bias to personal drug use reminders in an addiction Stroop task predicts relapse in treatment-seeking, cocaine-dependent subjects.
METHODS: We sought to maximize the potential of attentional bias as a marker of risk for relapse by incorporating individualized rather than generalized drug use cues to reflect the personal conditioned associations that form the incentive motivation properties of drug cues in a sample of cocaine-dependent subjects (N = 35).
RESULTS: Although a significant group Stroop interference effect was present for drug versus neutral stimuli (ie, attentional bias), the level of attentional bias for cocaine-use words was not predictive of eventual relapse in this sample (d = .56). A similar lack of prediction power was observed for a non-drug counting word Stroop task as a significant interference effect was detected but did not predict relapse outcomes (d = .40). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: The results of the present study do not provide clear support for the predictive value of individual variation in drug-related attentional bias to forecast probability of relapse in cocaine-dependent men. © American Academy of Addiction Psychiatry.
