Diathesis-stress

Cards (13)

  • what does NO TWIN STUDY have?
    100% concordance SO genes alone do not cause OCD
  • What do individuals inherit?
    a genetic vulnerability or genetic predisposition to OCD that has to be triggered by the environment to suffer with OCD
    this explanation is known as the DIATHESIS-STRESS MODEL
  • What is one strenght of the diathesis-stress model?
    holistic
  • what is this disposition in the case of the diathesis-stress model?
    a factor that makes it more likely that an individual will develop a disorder following a stressful life event
  • give the diathesis stress model>?
    DIATHESIS + STRESS --> DEVELOPMENT OF THE DISORDER
    A predisposition or vulnerability: inherited predisposition to inherit the disorder + environmental factors --> psychological disorder
  • the stronger the DIATHESIS......?
    ........the less stress is necessary to produce the disorder
  • what are examples of stress (environmental factors)?
    • prenatal trauma
    • childhood sexual or physical abuse
    • family conflict
    • significant life changes
  • what does diathesis refer to?
    a predisposition or vulnerability to developing a mental disorder. this can be due to genetic factors, early life experiences or other biological susceptibilities
  • what does stress refer to?
    the environmental factors that trigger the onset of mental illness or exacerbate existing conditions. these can include significant life events, trauma and daily stressors
  • what does the model suggest?
    you are born with a genetic vulnerability to a disorder which will only be expressed if triggered by the environment
  • what approach is it to explaining behaviour?
    an interactions approach to explaining behaviour
  • what is unlikely?
    that ONE gene causes ocd
  • what did TAYLOR suggest?
    it is unlikely that ONE gene causes OCD, it is POLYGENIC - 230 genes may be involved (taylor)
