I am writing my research using the GT of Strauss and Corbin. However, typical research templates always have this Conceptual or Theoretical Frameworks.
Grounded theory rather discovers new theories based on real data. As you May Anne Logo Batain mentioned, other research tries to prove or refute theories hence the need for a conceptual framework or theory in the research. Grounded theory is an inductive research method for discovering new theories without any hypothesis about the outcome. It does not concerned itself with validation or description. The data the researcher collects rather guide analysis and theory creation.
