the interactionist approach

Question 1

the interactionist approach

Answer 1

bio and psych factors are involved in the development of sz.

Question 2

the diathesis- stress model

Answer 2

an interactionist approach to explaining behaviour. e.g sz is explained as the resultof both an underlying vulnerability (diathesis) and a trigger, both of which are necessary for the onset of sz. In early versions of Meehl’s model vulnerability (diathesis) was entirely genetic, the resultof a single ‘schizogene’ and triggers were psychological. Nowadays both genes and trauma are seen as diathesis , and stress can be psych or bio in nature.
