The conceptual framework applied in qualitative methods of evaluating evidence entails assessment of the processes, meanings, experiences and perceptions that the study subjects, including patients have regarding a particular variable under evaluation. Thus the qualitative approach does not apply measurable parameters. To analyze the relevant evidence, interpretation and using of emphatic comprehensions is applied, which implies that the findings and the variables are dependent on the context of the research study (Liddle, Williamson, & Irwig, 2011).
