Types
Psychiatrists classify abnormal personalities according to one or other of the detailed schemes set out in ICD-10 and DSM-IV.
For other doctors, who treat people with highly abnormal personalities less often, a simpler scheme is usually adequate.
Such a scheme is compatible with the specialist classifications (with one exception— lacking self-esteem). Each of the groups in this scheme will be described together with its relationship to the specialist classification, which is shown below.
Note that:
- the category for personalities lacking self-esteem and self confidence is included in neither DSM-IV nor ICD-10;
- cyclothymic and schizotypal ‘personalities’ are not included in the classification of personality disorder, but in ‘two minds mood disorder’ and ‘schizophrenia’, respectively, due to their close epidemiological links to those disorders.
A simplified classification of personality:
- Anxious, moody, and prone to worry
- Lacking self-esteem and confidence
- Sensitive and suspicious
- Dramatic and impulsive
- Aggressive and antisocial
Classification of personality disorders in DSM-IV and ICD-10 (generally, the same terms are used in DSM-IV and ICD-10; where there are differences the ICD term is shown in parentheses):
-
Anxious, moody, and prone to worry e.g.:
- Avoidant (anxious)
- Obsessive-compulsive (anankastic)
- Dependent
- Affective (depressive, hyperthymic, cyclothymic)
-
Sensitive and suspicious e.g.:
- unreasonable
- Schizoid
- Schizotypal (ICD-10: classified with schizophrenia)
-
Dramatic and impulsive e.g.:
- Histrionic
- Borderline (emotionally unstable—impulsive)
- self-centered
-
Antisocial e.g.:
1.Anxious, Moody and Prone to Worry Personalities:
(i) Avoidant (anxious) personality disorder i.e.:
These people are persistently anxious, ill at ease in company, and fearful of disapproval or criticism. They feel inadequate and are timid. They avoid taking new responsibilities at work and avoid new experiences generally. This tendency to avoid is the basis of the DSM term avoidant.
Characteristics of anxious, moody, worry-prone personalities i.e.:
- Persistently anxious
- Worried about day-to-day problems or health
- Inflexible, obstinate, indecisive (obsessional traits)
- Persistently gloomy and pessimistic or
- Unstable moods, mild elation, or overconfidence alternates with mild depression and/or selfdeprecation
(ii) Obsessive-compulsive (anankastic) personality disorder:
These people are inflexible, obstinate, and rigid in their opinions, and they focus on unimportant detail. They are indecisive, and having made a decision they worry about its consequences.
They are humourless and judgemental, while worrying about the opinions of others. Perfectionism, rigidity, and indecisiveness can make employment impossible.
They appear outwardly controlled but may well be irritated by those who disturb their carefully ordered routine, and may have violent feelings of anger.
(iii) Dependent personality disorder:
These people are passive and unduly compliant with the wishes of others. They lack vigour and self-reliance, and they avoid responsibility. Some achieve their aims by persuading other people to assist them, while protesting their own helplessness.
Some are supported by a more self- reliant partner; left to themselves, they have difficulty in dealing with the demands and also responsibilities of everyday life.
(iv) Persistent mood disorders:
These disorders represent a lifelong tendency to persistent gloom, elation, or varied mood which is abnormal, but not severe enough at any one time to constitute depressive or wild episodes.
Because of the close epidemiological links that we now know exist between these disorders and the mood (affective) disorders, the ‘affective personality disorders’ are now classified among the mood disorders in both DSM-IV and ICD-10. These people have lifelong abnormalities of mood regulation, as follows:
a.Dysthymia (ICD-10 and DSM-IV): Formerly depressive personality disorder. The person is persistently gloomy and pessimistic with little capacity for enjoyment.
b.Cyclothymia (ICD-10 and DSM-IV): Formerly cyclothymic personality disorder. The person’s mood alternates between gloomy and elated over periods of days to weeks. This instability can be particularly disruptive to work and social relationships.
2.Personalities lacking Self esteem and Confidence:
This group is common and important in primary care and general medical practice. These personality features are associate with recurrent depressive moods, eating disorders, and self-harm and are often see among young people who seek help for these problems.
Unfortunately, this group does not appear as a separate entity in the specialist classifications of personality disorder.
Characteristics of personalities lacking self-esteem:
- Lack confidence
- Feel inferior
- Expect criticism
- Strive to please others
- Shyness and social withdrawal/inappropriate efforts to please others
3.Sensitive and Suspicious Personalities:
People in this group are difficult to engage in treatment and they may distrust their doctors:
Characteristics of sensitive and suspicious personalities:
- Sensitive, touchy, irritable; see rebuffs where none exist
- Suspicious, mistrustful
- Cold, detached,show little concern for others,reject help when it is offered
- Eccentric, with unusual ideas about topics such as telepathy
- Self-sufficient
- Lacking concern
(i) Paranoids personality disorder:
These individuals are sensitive and suspicious; they mistrust others and suspect their motives, and are prone to jealousy. They are touchy, irritable, argumentative, and stubborn.
Some of these people have a strong sense of self-importance and special ability, although they may feel that their potential has been stymied by others letting them down or deceiving them.
(ii) Schizoid personality disorder:
These individuals are emotionally cold, self-sufficient, and detached. They are introspective and may have a complex fantasy life.
They show little concern for the opinions of others, and pursue a solitary course through life. When this personality disorder is extreme, the person is cold, callous, and insensitive.
(iii) Schizotypal personality disorder:
These individuals are eccentric and have unusual ideas (e.g. about telepathy and clairvoyance) or ideas of reference. Their speech is abstract and vague, and their affect may be inappropriate to the circumstances. In ICD-10
4.Dramatic and Impulsive Personalities:
characteristics of dramatic and impulsive personalities:
- Seek the limelight, dramatize their problems
- Vain, self-centered
- Demanding of others, to an unreasonable extent, perhaps using ‘emotional blackmail’
- Act a part, self-deceiving, lack awareness of their image to others
- Impulsive, sometimes with harmful behaviours
- Short-lived enthusiasms but lack persistence
- Unrestrained emotional display
(i) Borderline personality disorder:
People with borderline personality represent an important clinical group that presents frequently to healthcare, including A&E departments.
The term ‘borderline’ refers to a combination of features seen also in histrionic and antisocial personalities, which are centred around impulsivity and poor self-control.
The term originates in the now abandoned idea that the condition was related to (on the borderline with) schizophrenia.
Note that ICD-10 uses the term emotionally unstable personality disorder for the same patient group. People with borderline personality disorder have intense but unstable relationships.
They have persistent feelings of boredom and emptiness, with uncertainty about personal identity and a fear of abandonment. Their moods may be unstable, with unwarranted outbursts of anger, and low tolerance of stress.
They are impulsive, and may engage in self damaging behaviours, such as reckless spending or gambling, reckless sex, chaotic eating, and substance abuse. Threats or acts of self-harm may be recurrent.
(ii) Histrionic personality disorder:
These people appear sociable, outgoing, and entertaining but at the same time they are self-centred, prone to short lived enthusiasms, and lack persistence.
Extreme displays of emotion may leave others exhausted while the person recovers quickly and without remorse. Sexually provocative behaviour is common but tender feelings are lacking.
There may be astonishing capacity for self-deception and an ability to persist with elaborate lies long after others have seen the truth.
(iii) self-centered personality disorder:
This disorder is not included in ICD-10. Narcissism is morbid self-admiration. self-centered people have a grandiose sense of self-importance and are preoccupied with fantasies of success, power, and intellectual brilliance.
They crave attention, exploit others, and seek favours but do not return them.
5.Antisocial Personality:
This group corresponds to the dissocial (ICD-10) or antisocial (DSM-IV) groups in the specialist classifications. The difficulties are often increased by abuse of alcohol or illicit drugs.
Characteristics of antisocial personalities:
- Impulsive behaviour, low tolerance of frustration, and lack of consistent striving towards goals, leading to, for example, an unstable work record
- Callous acts, inflicting pain, cruelty, or degradation on others
- Tendency to violence
- Lack of guilt
- Failure to learn from experience, leading to behaviours that persist or escalate despite negative social consequences and legal penalties
- Failure to sustain close relationships, including intimate relationships
- Disregard of the feelings of others
- Family problems, including violence towards partner, and neglect of or violence towards children; frequent separation and divorce
- Often lengthy forensic history, perhaps starting with petty delinquent acts but escalating to callous, violent crime.
