If these really are mental health issues what can we do about them?
Personality is a controversial and divisive concept. It has many definitions but insufficient agreed understanding. The concept of personality is not just hard to define it is also problematic since it is open to distortion, misuse and stigma. Until recently it was thought that little could be done about mental health issues arising in the context of personality.
There is common agreement that personality probably refers to a recognisable and characteristic set of human behaviours, thoughts and feelings. These define our individual identity. How this works in every day life is important but personality is too often taken for granted. If we say we know someone we may not mean that we actually know what someone is truly like. By contrast there is something genuine and authentic about knowing someones personality. It is probably only known by those closest to us and it is a knowledge of a unique individual that is particular, longstanding and special. It means we can identify them and because we know their personality we think we can depend on them to behave or think or feel in a certain way. To put it more dramatically, if we know or love someone because of who they are, then we know or love them because we know their personality.
We assume that this personality is relatively fixed and persistent throughout life. Whether we are right or wrong about this is debatable but in everyday life we expect personality features to persist. When we rely on each other, in times of stress or difficulty we depend on these strengths and characteristics. In this way we may see personality features as enduring attributes helping each of us to adapt to challenge. Our personality should help us negotiate life through all its ups and downs.
Suppose instead that our particular set of personal characteristics is not helpful. What if our personality actually makes it more difficult to adapt in this way. Imagine how we might struggle if we had an enduring set of characteristics leading us in to repeated difficulties, making us and those around us feel very unhappy. This set of characteristics might have nothing to do with our wisdom or intelligence or status, and yet several enduring unhelpful traits may be recognisable and even characteristic. This is the definition of personality disorder; a characteristic, maladaptive and enduring set of thoughts feeling and behaviours, present since before adolescence and persistent through out adult life.
No single cause exists for personality disorder. As with so many concepts in mental health it is impossible and unhelpful to ascribe responsibility to either nature or nurture. Undoubtedly both are at play. The influence of genetic factors is evidenced by research but this evidence is balanced by evidence of the frequency and force of a childhood history of environmental disadvantage, trauma, neglect and loss.
Three broad groups or clusters of personality disorder are described by mental health definitions. These diagnostic groups are Cluster A (Odd or Eccentric), Cluster B (Dramatic or Histrionic) and Cluster C (Anxious or Dependent).
To best illustrate the challenges of personality disorder diagnosis let’s just consider issues arising form one of the most controversial of these disorders, a Cluster B disorder known as Borderline Personality Disorder or more recently known as Emotionally Unstable Personality Disorder (EUPD).
Common features described in EUPD are a tendency to
- difficulty controlling emotions
- feeling bad about yourself
- repeated self-harm
- feeling ‘empty’
- rapidly forming relationships and just as rapidly loosing them
- feelings of persecution
- and when stressed a tendency to hear noises or even voices.
The number of people with EUPD and even the number of people who receive this diagnosis is not clear. When you put all the personality disorders together studies estimate prevalence between 1 in 20 of the population and 1 in 5 of the population depending on the criteria in the the literature. For EUPD it is estimated (in the USA) that somewhere in the region of 1.5% of the population have this condition. None of these figures is truly reliable in my view. The real issue is the prevalence misdiagnosis, misuse of the diagnosis and/or under-diagnosis of these problems.
There are many reasons for scepticism regarding EUPD as a concept. EUPD is a diagnosis most frequently made by men, and most frequently about women in distress. Since EUPD was regarded as a problem beyond conventional treatment women given this label were routinely dismissed. More recently the diagnosis has been criticised by feminist sociologists and psychologists as an unhelpful paternalistic projection of male frustration leading inevitably to disregard of women with genuine psychological problems. A more emancipated view was articulated many years ago in a classic paper by Professor George Vaillant of Harvard University entitled “The beginning of wisdom is never calling a patient a borderline”. His problem solving approach is therefore very appealing.
A problem based approach to the EUPD as described by Vaillant allows a broader more inclusive and helpful response to people with emotional and mental health difficulties. Recognition of the persons problems in a neutral and unbiased way should not be beyond most health professionals. Only that way will the true prevalence of other conditions which commonly coexist with personality be accounted for. These include anxiety disorder, mood disorder, addiction and post-traumatic stress.
Better treatment of these subliminal and/or coexisting problems is not be the only benefit of a more holistic approach to patients with emotional instability. More recent developments have shown the benefit of modern psychotherapy for EUPD within what is known as the third wave of behaviour psychotherapies. These modern therapies build upon the insights derived from behaviour therapy (BT) and cognitive behavioural therapy (CBT) to offer newer more patient and solution focussed therapies. The evidence is that these can lead to better emotional regulation and more self control. The most immediately relevant of these is a therapy called Dialectical Behaviour Therapy (DBT)
DBT was developed by patients with ongoing difficulty in regulating intense emotion. DBT is effective because it teaches people skills for effectively managing their intense emotions. The therapy was developed by Professor Marsha Linehan herself a service user.
The real need for more trained therapist and greater access to this and other effective talking treatments is growing and yet providing sufficient psychotherapy for patients with this diagnosis is proving a great challenge. This is true for providers of mental health services whether in the HSE or this such as St Patricks in the independent sector. Nevertheless there is a real need to move beyond the historical denial and dismissal of people with personality problems. We need to work together instead to provide meaningful service and real hope of recovery to many more people previously regarded as beyond help.
