Attachement in adults- childhood attachemtn allow you to view the world in a felxible and trusting way, inceasing confidence and capacity to tolerate and resolve conflict.

Attachement in personlity disorders- unsfe and abusive experience of the world- will expect others to be histile, neglect, wont trust others, will feel overwhelmed by feelings osntead of managignhem.

35
Q

How are personliry disroders trested?

A

Problem with attachemnt
Need to restore idea of attachment i.e. as attachement figures.

Ensure pt sees same doctor.
Understand with the patient the crisis indicators- what happened before the episode of self harm- feeling rejected etc.
Appropriate boundaries (we have only 20 mins today for the consultation), contract to keep safe (ask for help if feeling unsafe)
Empowerement and recovery focused approach
Well co-ordinated, shared and coherent treatment
Good communication between different clinicians
Reflective practice groups, MDT meetings to understand pt.

Harm minimisation-
Self harm rleases endorphins so try to replace with something else. I.e. holding ice cube, elastic band- still harm but minimised.
Or alternative i.e exercise.

Boundaries- personality disorders have confused boundaries. Need to be clear to explain your rekationships, expectations of the service user and be consistent and reliable in what you said you would do.
