Development and validation of a new Italian short measure of disgust propensity: The Disgust Propensity Questionnaire (DPQ).

An Italian nine-item self-report disgust propensity measure was developed to address the limitations of currently available tools. The Disgust Propensity Questionnaire (DPQ) was evaluated using two independent studies in nonclinical and clinical samples. The DPQ showed adequate factorial and construct validity, internal consistency, and temporal stability. It could discriminate between patients with obsessive-compulsive disorder with contamination-related concerns and all other groups. It is a very short and psychometrically sound measure to assess disgust propensity in Italian samples.
