Background:

Body dysmorphic disorder (BDD) is a mental health condition characterized by obsessive preoccupation with perceived flaws in appearance.
Accurate screening tools are crucial for early identification and intervention of BDD.

Purpose of the Study:

To evaluate the Dysmorphic Concerns Questionnaire (DCQ) as a screening tool for BDD.
To establish optimal cutoff scores for the DCQ to enhance BDD screening.

Main Methods:

The DCQ was administered to 244 undergraduate students and 57 BDD outpatients in Melbourne, Australia.
Undergraduates were also screened for eating disorders and BDD using established questionnaires.

Main Results:

BDD outpatients scored significantly higher on the DCQ compared to undergraduates, even after controlling for depression and social anxiety.
A DCQ cutoff score of 9 demonstrated high accuracy, correctly classifying 96.4% of BDD patients and 90.6% of undergraduates.

Conclusions:

The DCQ is a valid and reliable screening instrument for BDD.
The derived cutoff score of 9 facilitates efficient and accurate BDD screening in clinical settings.
