Media System Dependency Theory

Abstract

This entry reviews the historical background, assumptions, and theoretical propositions of micro‐level media system dependency theory (MSD) as adapted to empirically test associations between individual‐level variables. Micro‐level MSD theory was developed to explain the contingent, dynamic, and multilevel effects of mass media on individuals. Micro‐level MSD theory has developed theoretical propositions that address either the predictors or consequences of individuals' media dependency relationships. MSD has potential to evolve to explain the changing media environment.
