With Biopsychosocial approach (Engel,1977), resilience can be seen as a product of dynamic interactions between biological, psychological and social factors related to an individual. Similarly, Multi-system model of resilience (MSMR) talks about two levels of resilience which are internal and external and coping methods as a connector between them (Liu et al., 2017).
This model also talks about presence of various factors responsible for emergence of resilience.
I would like to know how these two approaches differ from each other and what are the commonalities between these two?
Any kind of input is appreciated. Thank you!
