Negative priming for threatening vs. non-threatening information in body dysmorphic disorder

Abstract

Background:

Individuals with body dysmorphic disorder (BDD) suffer from unpleasant, repetitive thoughts about imagined defects in appearance which are difficult to control.

Objective:

The purpose of this study was to test for deficits in cognitive inhibition in BDD.

Methods:

To test for deficits in cognitive inhibition in BDD, we applied a negative priming paradigm. Specifically, we explored whether BDD patients exhibit greater deficits in cognitive inhibition when lexical targets are threatening than when they are non-threatening.

Results:

Surprisingly, BDD patients exhibited deficits in cognitive inhibition only for non-threatening but not for threatening information.

Conclusions:

Although BDD patients often describe their negative thoughts about their appearance as distressing, they may experience them as valid and thus may not try to control them.
