Area of Science:

  • Psychiatry
  • Plastic Surgery
  • Psychometrics

Background:

  • Body Dysmorphic Disorder (BDD) involves preoccupation with perceived appearance flaws, causing distress and functional impairment.
  • BDD is more prevalent in individuals seeking plastic surgery, necessitating screening tools for surgeons.
  • The Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder (BDD-YBOCS) is the gold standard but requires mental health professional administration.

Purpose of the Study:

  • To develop and validate a user-friendly questionnaire for physicians to screen for BDD.
  • To assess the reliability and validity of the PILOT questionnaire against the BDD-YBOCS.

Main Methods:

  • A prospective cross-sectional study involving 149 adult patients seeking facial plastic surgery.
  • Participants completed the developed PILOT questionnaire and the BDD-YBOCS, administered by a psychologist.
  • Statistical analysis included correlation, sensitivity, specificity, and internal consistency (Cronbach's alpha).

Main Results:

  • A strong positive correlation (Spearman's rho = 0.79, p < 0.001) was found between PILOT and BDD-YBOCS scores.
  • The PILOT questionnaire exhibited high sensitivity (88.6%) and good specificity (77.2%).
  • Excellent internal consistency was confirmed with a Cronbach's alpha of 0.91.

Conclusions:

  • The PILOT questionnaire is a validated, practical, and reliable instrument for physicians.
  • It aids in identifying potential Body Dysmorphic Disorder in patients seeking plastic surgery.
  • This tool can improve early detection and management of BDD in surgical settings.
