The Interactionist Approach Flashcards
what is the interactionist approach
taking into account both biological and psychological factors when considering the development of SZ
what is the diathesis stress model
a vulnerability to SZ and a stress trigger are necessary in order to develop the disorder
outline meelhs diathesis stress model
1962
- the vulnerability is purely genetic
- there is a personality - “schizotype” that is more sensitive to stress
- if you dont have the gene, no amount of stress will cause SZ
explain the key study into the interactionist approach (procedure)
tiearni et al
- Reviewed hospital records of 20,000 women diagnosed with SZ.
- Identified mothers who had one or more children adopted away.
- Sample: 150 high-risk adoptees (with SZ family history) and 150 low-risk adoptees (without SZ family history).
- Both groups assessed at 12 and 21 years old.
- Family functioning also assessed.
explain the key study into the interactionist approach (findings)
tiearni et al
- of the 300 adoptees, 14 developed SZ over the course of the study
- 11 were from the high risk group
outline gottesmans research
- reviewed SZ cases
- 48% concordance rate in identical twins
- 17% for non identical
what is tghe treatment according to the interactionist approach
combining drug treatment with therapy
outline supproting research into the interactionist approach to treatment
tarrier et al
- patients randomly placed in routine care or routine care and CBT
- patients in combined treatment group had improvement in positive symptoms
- suggets interactionist approach is most effective
give 2 strengths of interactionist approach
- supporting evidence - gottesman + tarrier
- practical application - interactionist treatment
give 2 limitations of the interactionist approach
- mechanisms about how stress trioggers biological factors is unclear
- treatment doesnt succesfully identify the cause
