Types of Personality Disorder
Personality disorders may be grouped into subtypes or 'styles'. There is some controversy surrounding this - people do not generally fit into one neat box. There is also some confusing or inconsistent terminology between different diagnostic manuals.
However many front-line staff often find it useful to recognise what main style(s) a patient may exhibit. This can help predict behaviour and what skills may be most useful. It can also help patients understand their issues better and access appropriate resources.
Five of the most relevant subtypes are:
1. Emotionally unstable
(also known as borderline): Characterised by emotional instability and impulsivity. Feelings of abandonment often trigger self harm and crisis presentations
2. Antisocial (also known as dissocial): Characterised by a fragile self esteem dependent on establishing superiority over others. Threats to self esteem can trigger angry or violent outbursts. Risk taking behaviour is driven by core beliefs that usual rules and consequences do not apply to them.
3. Paranoid: Characterised by a pervasive distrust of others, or organisations. Associated with frequent or vexatious complaints, and severe difficulty in establishing a therapeutic alliance
4. Dependent: Strong external locus of control, with the feeling of not being an actor in ones own life. Associated with medically unexplained symptoms and frequent presentations.
5. Avoident: Best understood as character based 'hard wired' anxiety (as opposed to episodic anxiety). Horizons can march inwards e.g. periods of sick leave leading to loss of job, to not leaving the house, the room, the bed. Associated with strong feelings of shame.
