In adults with a personality disorder how effective is Cognitive Analytic Therapy compared to any other intervention for improving patient outcomes?

Analytic Therapy (CAT) in people with borderline personality
disorder was very limited. The results of one small randomised
controlled trial (RCT) suggested that treatment with CAT may

findings may be unreliable, due to the high proportion of
participants missing from the analyses (between 24% and 65%, for
different outcome measures). Results may also have limited

personality disorder, whilst 88% had multiple personality
Further research is needed to adequately determine the
effectiveness of CAT in people with borderline personality disorder
and to compare CAT to other active treatment options.
