I want to know the answer to the following question:
Who developed the ISA?
All the background I'm provided with is that "Weinreich's Identity Structure Analysis (ISA), is "a structural representation of the individual's existential experience, in which the relationships between self and other agents are organised in relatively stable structures over time … with the emphasis on the socio-cultural milieu in which self relates to other agents and institutions" (Weinreich and Saunderson, (eds) 2003, p1).". Is that enough to answer the question?
Answer: yes
