Abstract

Background: Body dysmorphic syndrome (BDD) is a psychiatric disorder characterized by dissatisfaction with and disapproval of cosmetic surgery outcome.

Objective: The aim of this study was to study the reliability and validate the Thai version of the cosmetic procedure screening (COPS) questionnaire.

Methods: Fifty-six Thai women attending the gynecologic outpatient clinic at King Chulalongkorn Memorial Hospital were recruited into the study between July 2017 and June 2018. Four participants dropped out because they did not answer the second questionnaire. The original English-version of COPS was translated into the Thai version and back-translated by another linguist. The content of the questionnaire was validated by two urogynecologists. After signing their informed consent forms, the patients were asked to complete the Thai version of the COPS questionnaire at first visit. Thereafter, at two-week intervals they completed and sent back the questionnaires by mail.

Results: The average age of participants was 34.1 + 6.4 years. The correlation coefficient of each item (Q) score with the total score of the Thai version COPS questionnaire ranged from 0.17 to 0.74. The internal consistency (Cronbach’s alpha) of the questionnaire was 0.9. The weighted Kappa of each score ranged from 0.6–1.0. The mean total scores of the 1st and 2nd assessments (points) were 22.9 + 8.7 and 23.9 + 8.0. The intraclass correlation coefficient (ICC) (95% confidence interval (CI)) of the total score was 0.9 (0.9–1.0).

Conclusion: The findings of this study indicate that the Thai version of the COPS questionnaire is reliable and valid. It can be used for screening for BDD in Thai women before cosmetic surgery.
