Transcript of "Q2 03 - Modern Models and Prevalence"

  1. 1. Modern Perspectives<br />
  2. 2. Modern Models<br />Biological<br />Psychological<br />Sociocultural<br />Diathesis-Stress<br />
  3. 3. Biological<br />Emphasises role of:i) nervous system in mental disordersii) brain malfunctioniii) neurotransmitter imbalanceiv) genetic factors<br />Many mental disorders show a high degree of concordance amongst close relatives. <br />Techniques for observing brain functions have improved (MRI, PET)<br />
  4. 4. Psychological<br />Often, disorders occur without any apparent underlying biological cause.<br />Psychological model emphasises the role of basic psychological processes, cognitive factors, and unconscious forces and conflicts within the individual<br />
  5. 5. Sociocultural<br />Emphasis on the role of social variables (external factors) as potential causes of mental disorders.<br />E.g. poverty, unemployment, education, prejudice.<br />
  6. 6. How do you think living in this environment would influence your psychological health?<br />
  7. 7. Diathesis-Stress Model<br />Suggests disorders result from the joint effects of:i) a predisposition for a given disorder, termed a diathesisii) stressors in an individual’s environment that tend to activate or stimulate the predisposition or vulnerability<br />Other words – for various reasons, individuals show varying degrees of vulnerability to specific disorders and whether (and to what extent) it surfaces depends on the environment.<br />E.g. PTSD<br />
  8. 8. Assessment and Diagnosis<br />Assessment – When the psychologist gather information on a new patient (kind of problems, current conditions, responses to various psychological tests).<br />Diagnosis – identification of the person’s problem(s).<br />Psychologists and other mental health professionals have an agreed-upon system for describing and classifying mental disorders.<br />Most widely used – Diagnostic and Statistical Manual of Mental Disorders – IV (DSM-IV)<br />
  9. 9. Diagnostic and Statistical Manual of Mental Disorders – IV (DSM-IV)<br />Published by the American Psychiatric Association (1994).<br />Designed to help all mental health practitioners correctly diagnose specific disorders.<br />Describes about 250 disorders that are divided along five different categories, called axes.<br />Psychologist/Psychiatrist then assesses the person on each of these axes<br />

  11. 11. Prevalence in Australia<br />The National Survey of Mental Health and Wellbeing by ABS (2007)<br />Sample of 8,841 respondents aged between 16 and 85.<br />Women were more likely than men to have experienced symptoms of a mental disorder (22% of women compared to 18% of men) and young women reported the highest rates (30% for those women aged 16 to 24).<br />Young people were much more likely to report a mental disorder in the previous twelve-months (26%) and there was a steady reduction in this rate with increasing age.<br />
  12. 12. PREVALENCE OF 12 MONTH DISORDERS <br />
  13. 13.
  14. 14. SERVICE USE BY DISORDER TYPE<br />
  15. 15. SERVICE USE BY AGE AND SEX<br />
  16. 16. MEDICATION USE BY DISORDER TYPE<br />
