Techniques in the treatment of multiple personality disorder.

Multiple personality disorder, once considered to be rare, is being diagnosed with increasing frequency in the 1980s. The purpose of this paper is to present and discuss twenty techniques used in the treatment of multiple personality disorder. The primary treatment is psychotherapy but a number of adjuvant interventions are also required. The techniques discussed should be of use to therapists and represent a step towards definition of a treatment package for controlled trials, of which none have been conducted to date.
