Can cognitive bias modification simultaneously target two behaviors? Approach bias retraining for alcohol and condom use.

Abstract

This study tested the effectiveness of a cognitive bias modification (CBM) intervention to simultaneously reduce approach biases toward alcohol and increase approach biases toward condoms among high-risk young adults. Participants (N = 102) were randomly assigned to either a training condition or a sham-training condition. Participants in the training condition were trained to make avoidance movements away from alcohol stimuli and approach movements toward condom stimuli over four training sessions. Approach biases and behavior were assessed at pretest, posttest, and 3-month follow-up. Approach biases changed for both stimulus categories in accordance with training condition. Condom behavior and attitudes also changed as a function of training condition, such that participants in the training condition reported fewer instances of condom nonuse and a more positive attitudes toward condoms at a three-month follow-up. Participants in both conditions had significant reductions in alcohol consumption following the intervention and did not differ by training condition.
