The role of disgust propensity in blood-injection-injury phobia: comparisons between Asian Americans and Caucasian Americans.

There is a growing body of evidence suggesting the potential role of disgust propensity in blood-injection-injury (BII) phobia. The current study examined associations between disgust propensity and BII phobia symptom severity in Caucasian Americans (n=310) and Asian Americans (n=223). Asian Americans typically scored higher than Caucasian Americans on the BII and disgust measures. The present study also examined the structural relations between gender, cultural background, disgust propensity, and BII phobia symptom severity. According to the structural equation model, disgust propensity was significantly related to levels of BII phobia symptom severity and fully mediated the relationships between BII phobia symptom severity and the demographic variables of gender and cultural background. The implications of the results for cultural refinements to our understanding of disgust propensity and BII phobia are discussed.
