Measuring Obsessions Without Worry: Convergent and Discriminant Validity of the Revised Padua Inventory in an Icelandic Student Population

Psychometric properties of the Repetitive Thinking Questionnaire in a clinical sample

“…Evidence for convergent and discriminant validity, as well as factor structure has been demonstrated (Burns, Keortge, Formea, & Sternberger, 1996;Jónsdóttir & Smári, 2000). Internal consistency (˛ = .92) and temporal stability (r = .61-.84 across subscales over 6-7 months) are good (Burns et al, 1996).…”

Achieving certainty about the structure of intolerance of uncertainty in a treatment-seeking sample with anxiety and depression

“…Although subscale scores are available, the total score was used in the current study. Evidence of construct, convergent and discriminant validity has been demonstrated (Burns, Keortge, Formea, & Sternberger, 1996;Joǐnsdoǐttir & Smaǐri, 2000). The PI has been shown to discriminate between individuals with OCD, other anxiety disorders, and non-clinical controls (van Oppen, Hoekstra, & Emmelkamp, 1995).…”

Measuring obsessive-compulsive symptoms: Padua Inventory-Revised vs. Yale-Brown Obsessive Compulsive Scale

“…This yields an advantage over the Y-BOCS Checklist since symptoms are assessed dimensionally. Much interest in recent years has been drawn to the use of the PI to research the typology of OCD symptoms in various countries and cultures (see Goodarzi & Firoozabadi, 2005;Jó nsdó ttir & Smá ri, 2000;Kyrios, Bhar, and Wade, (1996); Macdonald & de Silva, 1999). A second explicit aim of the PI is to assess OCD severity through a summation of all symptom frequencies, as indicated by Sanavio (1988): ''.…”
