- Diathesis-Stress Model. Explaining Sz. AO3
- WALKER (1997)
- Cortisol levels higher in sz patients compared to non sufferers
- Cortisol levels related to severity of symptoms
- Increased cortisol levels=heighten genetically influenced abnormalities in dopamine transmission
- Underpin vulnerability to sz, triggering onset of disorder
- cortisol levels=higher immediately before onset of sz, suggest s trigger rather than effect
- DIFFERENTIAL SUSCEPTIBILITY HYPOTHESIS
- Extends the diathesis stress model
- Includes both positive & negative environments
- Eg: An individual with a genetic vulnerability but exposed to a positive environment eg: a loving family background could reduce their chances of developing sz
- Real life application
- CAUSES MAY VARY
- Lacks aetiological validity
- Not known exactly how different stressors contribute to the diathesis-stress model for any one person because specific causes may differ between individuals
- WALKER (1997)
