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)
