Cognitive behavioural therapy (CBT) has shown promising results as a treatment for body
dysmorphic disorder (BDD). This review investigates the evidence for the factors
suggested to maintain BDD in the two predominant CBT models. PsychInfo and
MEDLINE searches were conducted using terms from the CBT maintenance models
which yielded 33 papers. All maintenance factors had been investigated at least once,
with mixed support indicated for most factors. The behavioural factors have received the
most research support and there is good evidence that safety-seeking behaviours such as
avoidance, rumination and rituals are common in BDD and less clear evidence for other
factors. However, as yet no studies have investigated the extent to which these factors
maintain symptoms of BDD.
