Answer for DNP 820 Compare and contrast qualitative, quantitative, and mixed-method research Re: Topic 4 DQ 2
The approaches in research are plans and procedures spanning the steps from broad assumptions to detailed methods of collecting data, analysis, and interpretation involving several decisions based on the nature of research problems and audience for the study (Creswell & Creswell, 2018). Qualitative, quantitative, and mixed methods are the three approaches to research.
Qualitative research involves emerging questions and procedures, data analysis, and interpretation of the meaning of data by a researcher. It is an approach to understanding and exploring the meaning of a problem. On the other hand, quantitative research is testing objective theories by checking the relationship amongst variables that can be measured, and the numbered data using statistical procedures can be analyzed. The final written report has a structured set consisting of an introduction, theory and literature, methods, results, and discussion. Mixed methods research is an inquiry involving quantitative and qualitative data collection, integrating the two forms of data and using designs involving philosophical assumptions and theoretical frameworks.
When choosing primary research, systematic reviews of randomized controlled trials are the strongest level of evidence to guide interventions in clinical practice (Melnyk, 2016). In order to support my DPI project interventions, it is important to locate evidence relevant to guide nursing practice and improve patient care outcomes and quality care, as well as know the importance of how to critically appraise and synthesize to determine whether the studies are reliable, valid and applicable to the PICOT question. Reliable study results indicate that the influence on patient outcomes is sufficient.
