What do we mean by mental disorder?

Who has a mental disorder?Mass murders?People who want to cut off their arms

and legs?People who can’t pay attention and

concentrate?

Is the concept of ‘Mental Disorder’ problematic? “I should like to make clear, therefore, that

although I consider the concept of mental illness to be unserviceable, I believe that psychiatry could be a science. I also believe that psychotherapy is an effective method of helping people – not to recover from an ‘illness’ but rather to learn about themselves, others and life.” Szasz

Two broad ways to define mental disorder

In general, the concept of “mental disorder” can be defined as:A biomedical, culturally independent,

value-free conceptOr as a social, culturally relative,

value-based concept.

Overview of definitions that will be discussed Mental disorder as a statistical deviation Mental disorder as dysfunction Mental disorder as personal discomfort Mental disorder as maladaptive

behaviour Mental disorder as norm or value

violation

Mental disorder as statistical deviance

A person has a mental disorder when their behaviour, ability, or experience is significantly different from average.

Mental disorder as statistical deviance

Mental disorder as statistical deviance Problems: We want to use the term disorder to

describe some conditions that are statistically frequent

“positive” deviations are not distinguished from “negative” deviations

we do not want to call all “negative deviations a disorder

Uggo Betti: “All of us are mad. If it weren’t for the

fact that every one of us is slightly abnormal, there wouldn’t be any point of giving each person a separate name.”

Mental disorder as a dysfunction

A person has a mental disorder when a mental mechanism is not performing the natural function it was designed to perform.

Problems:Natural selection does not “design”

mechanisms

Sedgwick (1982): “All sickness is essentially deviancy

from some alternative state of affairs which is considered more desirable…The attribution of illness always proceeds from the computation of a gap between presented behaviour (or feeling) and some social norm.”

Mental disorder as a dysfunction

Problems cont:For many mechanisms there is a wide

range of adaptive functioning across people and situations (fear response).

Mental disorder as a dysfunction

Problems cont:Many things that we want to call a

disorder might actually be adaptive reactions.

Mental disorder as personal discomfort

A person has a mental disorder if they experience personal distress.

Problems:What about the person who abuses

drugs or believes they are receiving messages from outer-space – without experiencing distress?

Mental disorder as maladaptive behaviour

A person has a mental disorder if they engage in behaviour that prevents them from meeting the demands of life.

Problems:There may be situations that people

should not adapt toThis approach emphasizes “fitting in” as

being ultimately important

Mental disorder as norm or value violation A person has a mental disorder if they

have experiences and exhibit behaviours that are inconsistent with the norms and values of society.

Examples:Behaviour that is harmful to oneself or

othersPoor reality contactInappropriate emotional reactionsErratic behaviour

Mental disorder as norm or value violation

Problems:What if violation is result of external

circumstancesSuch a criteria can seem too arbitrary

and open to abuse

DSM-IV definition of mental disorder

A mental disorder is “conceptualized as a clinically significant behavioural or psychological syndrome or pattern that occurs in an individual and that is associated with present distress or disability or with a significantly increased risk of suffering death, pain, disability, or an important loss of freedom.”

DSM-IV definition of mental disorder “The syndrome or pattern must not be

merely an expectable and culturally sanctioned response to a particular event, for example, the death of a loved one.”

“It must currently be considered a manifestation of a behavioural, psychological, or biological dysfunction in the individual.”

Cross cultural issues

How one thinks about the role of culture depends on your definition of mental disorder

Cross cultural issues

If biomedical, then culture influences how a disorder impacts members of different culturesDifferent riskIdiom of distress

Cross cultural issues

If culturally based, then influences what will be considered a disorderBehaviour or experience may not be a

“disorder” in all cultures

Non-Western approaches to mental disorder

Often do not separate psychology and spiritualityDisruption in relation to spirit world

Often based on more collective and less individualistic conceptualizationsDisruption in interpersonal relations
