My research is being designed to investigate the efficacy of a culturally appropriate and targeted diabetes education program on the reduction of A1C levels after six months. The population I am focusing on is Asian Americans with Type II diabetes, within a specific age range. My hypothesis is that after three months of the program, the A1C levels of the experimental group will be lower than they were prior to starting the program.
Because I intend to measure the same population of people before and after the intervention, the ideal methodology to be used would be a pre/post test. I would like to employ quantitative research methods regardless, particularly for measuring the dependent variable (A1C levels). This is a unifactorial study, focusing only on one diabetes factor (A1C levels), making it relatively straightforward. Another way I can approach this study is to design a correlational study in which I compare two different samples of Asian Americans with diabetes. However, the pre/post method controls for intervening variables because it is testing the exact same group. I need to operationalize the education intervention and clearly define how it will be implemented in the research.
The opposite methodology, such as qualitative methods, may be useful if I were to change my research question. Qualitative methods used may include interviews or case studies. For example, in addition to measuring A1C levels, I would also measure patient perceptions of the program, and other subjective markers. It might be helpful to do so in order to determine whether the program needed to be redesigned. Both qualitative and quantitative methods are efficacious in evidence-based practice but not all research questions can be appropriately designed as quantitative studies. I happen to have a research question that does lend itself to quantitative analysis.

A person’s epistemology or way of knowing also informs perceptions. Thus, a patient’s worldviews, values, attitudes, background, and beliefs will all impact how that individual perceives healthcare delivery and health itself. The subjective way of knowing is all about perceptions, not about measurable, verifiable reality. For example, many patients do not care about numbers in their chart or whatever percentage of persons benefitted from a specific treatment intervention. The patient also cares more about how the nurse communicates, and whether eye contact or touch was used, and less about whether the nurse referred to clinical studies before recommending a course of treatment. What the patient cares about is how they feel, and whether their perceptions align with their expectations. Nurses need to understand the salience of subjective reality.
If patients had an objective paradigm of the world, they would have a detached view towards their health and treatment options. They would make decisions based on calculations and algorithms, not on psychological motives. Even nurses who are guided by evidence-based practice models still do operate within a subjective paradigm of the world. It is important to recognize the difference between subjective and objective ways of knowing when…

Nursing Research and EVP Nursing Research & Evidenced-Based Practice The objective of this study is to examine how evidence-based practice and nursing research are supported and implemented throughout the organization. Secondly, this study will examine the nurses' role in research and evidence-based practice, the steps sued for research and evidence-based practice and the model for evidence-based practice. Role of Nurse in Research and Evidence-Based Practice Evidence-based practice is a term that is used to
Nursing Research How Data Collection Influences Statistics Data collection influences statistics in several ways. First, data is collected according to a "category scheme," which is the establishment of meaningful categories in which the data is collected and analyzed (Polit & Beck, 2008, p. 508). If the category scheme is not well developed and meaningful, adequate data may not be effectively collected and examined to inform the nurse researcher about whatever topic he/she
" (p.4) DATA ANALYSIS PROCEDURES Data analysis involved "immediate debriefing after each focus group with the observer" and during this time, debriefing notes were recorded containing comments related to the process of the focus group and the data's significance. Secondly, the tape was listened to and the content of the tape transcribed. Third stated is that the tape's content was check and non-verbal behavior given consideration by the researchers.

In order to better understand women's understanding of unforeseen and upsetting indications in the time after dynamic cancer management, this qualitative secondary examination looked at how women looked at unforeseen and upsetting indication practices. Re-examination of phenomenological statistics from the first author's investigation on survivor loneliness exposed adequate knowledge in order to conduct this secondary data analysis. 9) How was the sample selected?

It is also quite possible that there is a significant "placebo effect" when dealing with GI (or other) treatments. The patients may be truly relaxing, but may also believe that they are managing their pain through breathing and imagery, meaning they are, in fact doing just that (Bresler; Menzies).

Descrptive Design Research Method and Design Proposal A research design is the approach utilized for a study used as a guide in gathering and analyzing data. There are two popular methods of research; qualitative and quantitative research methods. Qualitative research is an inductive, holistic, subjective, and process-oriented method technique employed to understand, interpret, describe, and establish a theory on a given topic, phenomena, or setting. Investigators employ this technique when their studies
