Content of the questionnaire
Target audienceAdults
ApplicationThe Padua Inventory – Washington State University Revision (PI-WSUR) has been developed to capture symptoms of obsessive-compulsive disorders. Furthermore, it has been designed to differentiate among different categories of symptoms in OCD.
CompositionThe 39 items of the PI-WSUR are rated on 5-point Likert scales ranging from 0 = “Not at all” to 4 = “Very much”.
Psychometric properties
Reliability & ValidityThe psychometric properties of the PI-WSUR have been investigated in a large study with N = 5010 participants. In this way, reliability and validity, as well as initial support for the hypothesized underlying factor structure resembling OCD symptom categories has been found.
