Individual differences in disgust sensitivity: Comparisons and evaluations of paper-and-pencil versus behavioral measures

Sixty-eight undergraduate students experienced 32 hands-on tasks designed to provide a behavioral validation for the paper-and-pencil Disgust Scale, which the students had completed 2 months before. Tasks assessed participant-determined degree of exposure (looking at, picking up, touching, and in some cases eating) to objects such as a cockroach, cremated ashes, and a freshly killed pig's head and to disgusting video clips (seconds watching). These tasks elicited strong negative affect in a way that was ethical and not very disturbing to participants; they may be useful for future laboratory study of emotion. Participants also experienced nondisgusting control tasks, such as imitating a chicken or holding one's hand in ice-water. Analysis of task intercorrelations indicated four factors: food-related disgust, body-violation-and-death-related disgust, compliance motivation, and embarrassability. Only the mio disgust factors correlated significantly with the paper-and-pencil Disgust Scale; a combination of the two correlated.58 with Disgust Scale scores obtained months before the laboratory assessment and correlated.71 with scores obtained immediately after this assessment. Most generally, these results are a reminder that there is no gold standard for personality assessment. As with paper-and-pencil measures, behavioral measures require getting beyond face validity to assess threats to validity from factors such as embarrassment and compliance motivation.
