What constitutes treatment of personality disorder within a CMHT?

For an intervention to be considered a treatment for personality disorder, the primary goal must be to improve the difficulties associated with the patient’s personality disorder. A distinction can be drawn between treatments aimed at a patient “overcoming” their personality difficulties by seeking to initiate change in the patient, and treatment or interventions which “take account” of the personality difficulties in order to minimise the impact of the personality disorder on the patient and those around them. Examples of the former include psychological treatments like DBT and STEPPS and any skills reinforcement or skills generalisation carried out by the CMHT.

Examples of the latter include environmental management (interventions aiming to improve adaptive fit between the person and their environment), interventions aimed at changing the social or interpersonal environment (family interventions etc) and adaptations to standard interventions for another condition (changing the treatment approach for major depressive disorder in someone with a concurrent personality disorder).
