They are for - mental health nurses and social workers - therapists qualified in another field - clinical psychologists - medical practitioners - others in professional/psychological support services usually in the NHS. Cognitive Analytic Therapy (CAT) is an integrated approach developed in the UK. First developed to treat neurotic disorders in outpatient settings, in recent years it has developed for work with more severely disturbed, personality disorder problems. It is suitable for people whose primary disturbances are in interpersonal relationships. Like cognitive behaviour therapy, it can be used with people who lack the interest in self-exploration and the capacity to tolerate the frustration that may be important for success in psychoanalytic and psychodynamic therapies. It has been applied where there is some dissociation of different states of mind. CAT is proving to be effective in working with difficult or personality-disordered patients for whom disordered interpersonal relations are the main feature of their psychopathology and disrupt treatment. It is also proving to be helpful in working with the complex interpersonal reactions made by these patients in staff teams and institutions, which may often aggravate these problems unless understood and managed. This shows an emerging trend for using CAT as opposed to doing it as an individual therapy. This can lead to a greater understanding of the problems and service needs of patients by mental health teams.
