Critical Appraisal of Theoretical Framework

If a conceptual model was not used, explain how using a theoretical framework helps to situate the concepts of interest in the study.
If a conceptual model or theoretical framework was used, answer the following questions:
Describe how it helps explain the phenomenon of concern. 
How is the framework linked to the research purpose? Would another framework fit more logically with the study?
If a proposition or relationship from a theory is to be tested, is the proposition clearly identified and linked to the study hypothesis?
