摘要：Evidence suggests that cognitive bias modification paradigms (CBM-I) targeting interpretive biases can modify threat-based biases in anxious individuals, thereby reducing anxiety symptoms. However, no research to date has examined whether such paradigms can modify disgust-relevant biases. This is an important issue given evidence of disgust's role in a number of anxiety disorders. Sixty participants completed a computerised CBM-I task that trained either benign (n = 30) or disgust-based (n = 30) interpretive biases. The effects of training on the interpretation of novel material, behavioural avoidance, physiology, and self-reported symptoms were examined. Disgust-based, but not benign training increased self-reported disgust propensity, obsessive-compulsive symptoms and negative affect, from pre- to post-training, however, training did not affect the interpretation of novel material, behavioural or physiological responses. Results provide further evidence of disgust responses being particularly resistant to modification, and also highlight the need for CBM-I studies to include objective measures of emotional change in addition to self-report.
