Introduction: Body dysmorphic disorder (BDD) is a mental health condition defined by preoccupation with a non-existent or minimal flaw (defect) in appearance. This preoccupation causes significant social and occupational impairment, lot of distress and is not better accounted for by another mental disorder. The defect often regards the skin, face or body build. Data show that 8-14% of dermatological patients suffer from BDD, whereas in the cosmetic dermatology setting the incidence is reported as high as 8-37%. The Body Dysmorphic Disorder Questionnaire-Dermatology version (BDDQ-DV) is a screening tool that may help to diagnose patients with BDD in dermatology settings. The questionnaire is self-reported, therefore it can be used in daily dermatology practice.
Aim: To create and validate the Polish language version of the BDDQ-DV.
Material and methods: The Polish version of BDDQ-DV was created in accordance with international standards. To assess reliability of the questionnaire the Cronbach's α coefficient was used. The reproducibility (test-retest reliability) of the Polish language version of the questionnaire was evaluated using the interclass correlation coefficient (ICC) coefficient.
Results: The Polish version of BDDQ-DV was created. The Cronbach's α coefficient based on the first completion of the questionnaire was 0.92 indicating a correspondingly high internal consistency between the questions of the questionnaire. ICC was assessed at 0.998, which indicates excellent reliability.
Conclusions: The Polish version of BDDQ-DV may help to identify patients with BDD among Polish-speaking individuals.
