Social & health inequalities is about the differences in society basically. The term psychosocial refers to someones psychological development in thier particular social environment - how they develop (or not) and how this development is affected/enhanced by the interaction in that social environment. Erikson is the big name if I remember rightly he has a theory about the stages of development in relation to social environment. In short differing lifestyles and backgrounds mean you may develop differently, hence the term psychological dysfunction, where some people have problems with stages/development. Heres a brief outline of his theory its all about trust and shame etc
