  7. 7. 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 unser viceable, I believe that psychiatr y could be a science.

  9. 9. Two broad ways to define mental disorderIn general, the concept of “mental disorder” can be defined as: A biomedical, culturally independent, value-free concept Or as a social, culturally relative, value-based concept.
  10. 10. Overview of definitions that will be discussedMental disorder as a statistical deviationMental disorder as dysfunctionMental disorder as personal discomfor tMental disorder as maladaptive behaviourMental disorder as norm or value violation
  11. 11. Mental disorder as statistical devianceA person has a mental disorder when their behaviour, ability, or experience is significantly dif ferent from average.
  12. 12. Mental disorder as statisticaldeviance
  13. 13. Mental disorder as statistical devianceProblems:We want to use the term disorder to describe some conditions that are statistically frequent“positive” deviations are not distinguished from “negative” deviationswe do not want to call all “negative deviations a disorder
  14. 14.  Uggo Betti:  “Allof 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.”
  15. 15. Mental disorder as a dysfunctionA person has a mental disorder when a mental mechanism is not per forming the natural function it was designed to per form.Problems: Natural selection does not “design” mechanisms
  16. 16.  Sedgwick (1982):  “Allsickness 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.”
  17. 17. Mental disorder as a dysfunctionProblems cont: For many mechanisms there is a wide range of adaptive functioning across people and situations (fear response).
  18. 18. Mental disorder as a dysfunctionProblems cont: Many things that we want to call a disorder might actually be adaptive reactions.
  19. 19. Mental disorder as personal discomfortA 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?
  20. 20. Mental disorder as maladaptive behaviourA 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 to This approach emphasizes “fitting in” as being ultimately important
  21. 21. Mental disorder as norm or value violationA 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 others Poor reality contact Inappropriate emotional reactions Erratic behaviour
  22. 22. Mental disorder as norm or value violationProblems: What if violation is result of external circumstances Such a criteria can seem too arbitrary and open to abuse
  23. 23. DSM-IV definition of mental disorderA 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 suf fering death, pain, disability, or an impor tant loss of freedom.”
  24. 24. DSM-IV definition of mental disorder“The syndrome or pattern must not be merely an expectable and culturally sanctioned response to a par ticular 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.”
  25. 25. Cross cultural issuesHow one thinks about the role of culture depends on your definition of mental disorder
  26. 26. Cross cultural issuesIf biomedical, then culture influences how a disorder impacts members of dif ferent cultures Different risk Idiom of distress
  27. 27. Cross cultural issuesIf culturally based, then influences what will be considered a disorder Behaviour or experience may not be a “disorder” in all cultures
  28. 28. Non-Western approaches to mental disorderOf t endo not separate psychology and spirituality Disruption in relation to spirit worldOf ten based on more collective and less individualistic conceptualizations Disruption in interpersonal relations
  29. 29. The study of mental disorder involves:Definition: What do we mean by mental disorder?Categorization: How do we classify mental disorder?Explanation: How do we understand mental disorder?Treatment: How do we treat mental disorder?
