In adults with eating disorders (excluding binge eating disorder) how effective is group cognitive behavioural therapy (GCBT) when compared to cognitive behavioural therapy (CBT) in reducing eating disordered behaviours and preoccupation with eating, weight and shape?
No definite clinical implications can be made from the available
evidence. Two randomised controlled trials suggested that group
cognitive behavioural therapy (CBT) should be considered as a valid
alternative to individual CBT (after a few individual sessions at
the start), or as a first-line treatment in a stepped care approach
to treating bulimia nervosa.
It was suggested that more research on group CBT versus
individual CBT is needed to substantiate the current evidence. The
authors of one trial also suggested that future studies might also
want to conduct qualitative interviews to assess reasons for
drop-out, and the authors of another trial suggested that further
research should address how best to encourage abstinence of binging
and vomiting in patients undergoing group CBT.
