Schizophrenia - Interactionism Flashcards
Support for vulnerability and triggers
Tienari
19,000 finish children with schizophrenic mothers. They were compared to a control group in adulthood. High genetic risk vs low genetic risk. Child rearing style assessment for adoptees. Found that high levels of criticism and hostility and low levels of empathy is strongly associated with development of Sz but only in high risk group.
Both genetic vulnerability and family stress are required for an increased risk of developing Sz.
Original Diathesis stress model is overly simplistic.
The diathesis (vulnerability) cannot be a single schizogene. Sz is polygenic.
Stress cannot be a schizophrenogenic parent only. Abuse ad recreational drugs.
Houston et al found that sexual abuse was the major influence on underlying vulnerability to Sz and cannabis use is the major trigger.
Modern understanding of diathesis and stress is more appropriate.
Real world application +
COUNTERPOINT
Combination of bio and psych treatments increases their effectiveness.
Tarrier 315 participants assigned to drugs + CBT, drugs + counselling or jus drugs (control). Combination groups showed less symptoms after trial. But no difference in rehospitalisation. Support for adopting interactionist approach in treatment of Sz.
Counterpoint
Okami & Jarvis
Logical error - treatment-causation fallacy. (Ones ability to change an event proves what originally caused it) Alcohol reduces shyness but a lack of Alcohol cannot be said to cause shyness.
Support from urbanisation.
COUNTERPOINT.
Sz more commonly diagnosed in urban areas. Urban living is more stressfull. This stress can be the trigger to Sz. But more doctors in urban areas so easier to diagnose. Poverty drives people to urban areas.
