摘要

Contamination thought-action fusion (CTAF) and contamination sensitivity (CS) are cognitive distortions believed to play a role in the onset and maintenance of mental contamination (MC)-related obsessive–compulsive disorder (OCD). A parallel mediation analysis was used to examine the extent to which CTAF and CS explained the relationship between repugnant obsessions and MC in a sample of undergraduates (N = 564). As hypothesized, repugnant obsessions positively predicted MC (β = .499, SE = .050, p < .001), and the indirect effects through CS (β = .176, 95% CI = [.129, .226]) and CTAF (β = .050, 95% CI = [.009, .096]) were significant. These results suggest that CTAF, and particularly CS, may be important cognitive therapy intervention targets for clients experiencing MC triggered by repugnant obsessions (i.e., self-contamination). Furthermore, the present findings warrant experimental investigation of CTAF’s and CS’s potential causal roles in self-contamination-related OCD.
