What's the core difference between applied social psychology and social psychology?

Whereas the goal of social psychology,in general,is to develop and empirically test theories of social behavior,applied social psychology is concerned more specifically with understanding and finding solutions to social and practical problems by drawing on the knowledge base of existing theory and research,conducting research,and developing intervention strategies.It is the concern with the development of intervention strategies that is unique to applied social psychology and differentiates it from social psychology.
