AB  - Although the Psoriasis Epidemiology Screening Tool (PEST) questionnaire is a 
      useful tool for screening patients for psoriatic arthritis (PsA), it has not been 
      validated in Portuguese. Our aim was to perform a cross-cultural validation of 
      the PEST for Brazilian Portuguese, as well as to analyse its psychometric 
      properties and to test the association of PEST scores with patient clinical 
      characteristics. The first step was the translation and cross-cultural adaptation 
      of the PEST questionnaire into Brazilian Portuguese, which included forward 
      translation, synthesis, back translation, consolidation with an expert panel and 
      cognitive debriefing with pilot testing. The second step was validation and 
      psychometric testing, in which 124 dermatology patients with no previous PsA 
      diagnosis completed the new adapted questionnaire (PEST-bp). Patients were 
      initially assessed by a dermatologist for clinical characteristics, then they 
      answered the Dermatology Life Quality Index (DLQI) and PEST-bp questionnaires. 
      Afterwards, a rheumatologist, blind to former tests, evaluated the presence of 
      PsA according to CASPAR criteria. The PEST-bp proved to be 0.81 accurate (95% CI: 
      0.73-0.88) in the ROC curve, indicating a cutoff score >/= 3 as suggestive of PsA 
      (sensitivity = 84.6%, specificity = 63.3%). The assessment of internal 
      consistency, via the Cronbach test, presented a coefficient of 0.72 (acceptable). 
      A higher PEST-bp score was positively associated with lower quality of life 
      scores and with male patients. In conclusion, the PEST-bp questionnaire proved to 
      be suitable as a screening tool for PsA in patients with psoriasis. Elevated 
      PEST-bp scores are associated with decreased patient quality of life.
