Differential habituation of fear and disgust during repeated exposure to threat-relevant stimuli in contamination-based OCD: an analogue study.
J Anxiety Disord. 2009 Jan; 23(1):118-23.JA

Abstract

In the present study, participants (N=20) displaying marked contamination concerns were provided 30 min of repeated in vivo exposure to threat-relevant stimuli (cleaning a 'dirty' bed pan), during which time their fear and disgust levels were repeatedly assessed. Results indicated that repeated exposure led to a significant decline in fear but not disgust. The observed decline in fear remained significant after accounting for changes in disgust and vice versa. Although initial disgust was higher than initial fear ratings, differences between the two slopes were not statistically significant. Baseline trait anxiety and global disgust sensitivity levels prior to exposure did not moderate the level of fear or disgust activation during exposure. However, sensitivity specifically related to core and contamination disgust was marginally associated with fear and disgust parameters during outcome. There was also evidence that less fear decline during repeated exposure was associated with higher disgust ratings after the exposure was completed. Theoretical and clinical implications of the present findings for the treatment of contamination concerns in obsessive-compulsive disorder are discussed.
