The Dysmorphic Concern Questionnaire (DCQ) is a valid tool for identifying dysmorphic concern, a symptom linked to various disorders. While associated with body dysmorphic disorder (BDD), depression, and anxiety, negative body beliefs are key to BDD.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Mental Health

Background:

  • Dysmorphic concern is a symptom present in various psychiatric disorders.
  • A validated instrument is needed to measure dysmorphic concern.

Purpose of the Study:

  • To validate the Dysmorphic Concern Questionnaire (DCQ).
  • To examine the relationship between dysmorphic concern and depression, social phobia, and obsessive-compulsive disorder (OCD).

Main Methods:

  • Sixty-five psychiatric inpatients completed the DCQ, Body Dysmorphic Disorder Examination (BDDE), and measures of depression, social phobia, and OCD.
  • The study analyzed the factor structure and convergent validity of the DCQ.

Main Results:

  • The DCQ demonstrated reliability and validity in measuring dysmorphic concern.

  • Dysmorphic concern correlated with body dysmorphic disorder (BDD), depression, social phobia, and OCD.
  • Only the BDDE score predicted DCQ score in regression analysis, and negative body beliefs defined BDD symptomatology.

    • Conclusions:

    • Negative body beliefs are characteristic of BDD.
    • Dysmorphic concern does not automatically indicate a BDD diagnosis.
    • The DCQ is an efficient tool for screening dysmorphic concern in patients with depression, OCD, social phobia, or BDD.
