Analyses of mental contamination: Part II, individual differences.

Recent research on mental contamination (internal, psychological feelings of dirtiness) has focused primarily on examining the experimental variables necessary to provoke contamination-related thoughts, feelings and behaviour; yet, relatively little is known regarding the individual differences among participants' mental contamination responses to these situational and experimental characteristics. The purpose of this study was to determine whether variables associated with symptoms, beliefs and appraisals could predict the experience of mental contamination after an established provocation. Female undergraduate students (n = 70 from Part I of this study; Elliott & Radomsky, 2009), completed a series of questionnaires then listened to an audio recording and imagined that they were receiving a forced, non-consensual kiss from a man described as moral or immoral. Participants indicated the presence and degree of mental contamination and appraisals of the man and act, then completed a behavioural task for which spontaneous washing was recorded. Results indicated that, although symptoms of physical contamination were able to predict feelings of mental contamination, appraisal variables emerged as unique predictors of feelings of mental contamination. Results are discussed in terms of cognitive-behavioural conceptualizations of and treatments for contamination fears.
