Discuss the attempts to define abnormality and evaluate the practical problems associated with them

There are four main ways of deciding whether someone is abnormal, theses are:

  • Statistical infrequency
  • Violation of moral standards
  • Deviation from expected
  • Personal suffering, distress and dysfunction

Statistical infrequency assumes that any behaviour that is statistically infrequent is regarded as abnormal.  Behaviour and personality traits can be put into a normal distribution pattern and that most people do not stray very from the norm/average.  An example of this method in use is to assess mental retardation and mental genius, on the assumption it can be measured by an IQ test.  Scores are plotted against the normal distribution pattern and very high and very low scores are then regarded as “special”.  However high scores are often not regarded as abnormal in the way low scores or mental retardation is, just as great athletic ability is not regarded as abnormal.  ICD (international classification of diseases) and DSM (diagnostic and statistical manual of mental disorders) use the presence of symptoms to diagnose mental illness.  For the classification to be of real value then it must be valid and reliable.  Research has suggested that psychiatric research is notoriously unreliable and studies have shown that even very experienced psychiatrists only agree about 50% of the time outlined by Rosenhan’s experiment.  In this experiment he sent “patients” with pretend schizophrenia into a mental hospital and then they acted “sane”, in which some were retained for up to 30 days, in which he concluded that psychiatrists couldn’t tell the sane from the insane.

Szasz suggested that “madness” is manufactured to label those people in society who do not conform to rules of social or to conventional moral standards.  Society sets up rules for behaviour and anyone who breaks these rules are labelled deviant.  Historically deviant behaviour has been used to even lock up political dissidents, but in present western culture, the term “mental disorder” is not used to define mental “deviant” behaviour.  There are types of behaviour that are generally regarded as unacceptable such as rape where it is difficult to accept that violation of others is could possibly be normal.  In ...
