Sample Answer for NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design
Studies or research should go through a critical appraisal process in which the study is evaluated for validity, reliability and applicability (Melnyk & Fineout-Overholt, 2019). Reliability of a research design is the assessment of the intervention whether the intervention worked and the ability to reproduce similar results. Validity of a research study is verifying the study is accurate and the methods used to measure are accurate as well.
Validity is ensuring the results are close to the truth and did the researchers conduct the study using the best research methods (Melnyk & Fineout-Overholt, 2019).
In the article I used of effective implementation of QBL the reliability of this study could easily be reproduced in any facility. The intervention did work in showing the use of QBL vs. EBL was effective in increasing the awareness and monitoring of blood loss.
The results did not show QBL measured more effective than EBL but was highly effective in the early assessment and treatment for PPH. This study also revealed that this process could be reproduced and produce similar effects. The validity of the study showed the subjects were randomly chosen through a criterion that of similar maternal demographics (Coviello et al., 2019).
The results were compared preimplantation a post implementation with good quality data that is measurable and accurate as well as verifiable. Utilizing the definitions of reliability and validity can help evaluate the evidence you choose to use in a study to verify the data is accurate and you will be successful in our EBP project.

This is insightful. Studies or research should go through a critical appraisal process in which the study is evaluated for validity, reliability, and applicability. Validity and reliability are concepts applied to evaluate the quality of research processes (Keogh et al., 2019). The two approaches indicate how well the technique, method, or statistical tests measures what is being studied in the research processes. NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design
Validity is more concerned with the accuracy of the statistical measure, while reliability is about the consistency of a given measure. Reliability may also refer to the extent to which the statistical results can be reproduced in case the research is repeated under similar conditions (Coviello et al., 2019). On the other hand, validity refers to the extent to which the study results measure what they are expected to measure (Rose & Johnson, 2020).
Validity can also be applied to check how well the results correspond to the already established theories as well as other measures under the same concept.

In research, data findings must be valid and credible; therefore, reliability and validity are measurements applied to ensure this goal is achieved. Reliability is consistency in measurement when measured repeatedly using different methods or sample groups (Sileyew, 2019). Reliable measures are those with low chance of errors. Whereas validity is defined as the accuracy of the measurement (Sileyew, 2019). High reliability means the measurement is valid.
The translational study I selected for my EBP project focused on the effects of a structured educational program as it relates to hypertension. The program consisted of specific educational topics regarding hypertension, dietary modifications and encouragement of exercising. A multicenter randomized trial was employed in the design of this study which included a total of 256 participants in 13 centers who were randomly assigned to two groups.
Group one (intervention) received immediate patient education regarding blood pressure control and group two (control) received patient education six months later. Both groups were assessed after six and 12 months. In group one the office and home systolic blood pressure decreased significantly after six months in comparison to group two as reflected by p<0.01 (Perl et al., 2016).
According to Perl et al. (2016), this study has provided statistically significant evidence that patients who participate in a multifaceted educational program will manage hypertensive disease more effectively than patients who do not because of center-specific standards of care. This was demonstrated in the potential differences in blood pressure between the two groups reflecting the significant impact of the educational program (Perl et al., 2016).

This is insightful. In research, data findings must be valid and credible; therefore, reliability and validity are measurements applied to ensure this goal is achieved. While undertaking research processes, it is essential to consider validity and reliability. Validity and reliability are concepts applied to evaluate the quality of the research process (Klima et al., 2015).
The two concepts show how well a technique, method, or the test measures something in the research process. Reliability refers to the consistency of a measure while validity may refer to the accuracy of the measure. High reliability means the measurement is valid (Pietrabissa et al., 2020). The translational study I selected for my EBP project focused on the effects of a structured educational program as it relates to hypertension. Reliability may also refer to the extent to which the statistical results can be reproduced in case the research is repeated under similar conditions.
To ensure accuracy in the research process, there is the need for the researchers to consider both the validity and reliability (Fuller et al., 2020).
Epidemiology plays a significant role in the life of a researcher, particularly ones dealing with population health. As a study of diseases and their characteristics, they enable researchers to understand numerous aspects of the same and their impact on a population in question. Indeed, epidemiology illuminates various aspects of diseases since it is premised on the assumption that population health is affected by numerous risk factors.
In the process of researching and addressing the risk factors affecting a population, epidemiology elucidates a health population, highlights risk factors and then examine the association between the health of a population and the multifarious risk agents (Gulis & Fujino, 2017). In order to achieve the above, epidemiology adopts the usage of the famous host-agent-environment triangle for purposes of describing how an individual, hence a population, becomes ill.
The occurrence of a disease happens when an individual interacts with a vector. Whereas the latter has to be capable of causing a disease, the former has to be vulnerable to the same (Frerot et al., 2018). The interaction occurs within an environment that provides an enabling setting. However, epidemiology is not just limited to the interaction between the host and the vector within an environment, but also extends to the analysis of the health status of the people or population inhabiting the environment.
The epidemiological undertakings by scientists have changed greatly as new datasets and disciplines have been introduced to the study of diseases. For instance, the epidemiology of heart conditions will entail the examination of risk factors at a community level, say, among African-Americans. During such a study, conceptual frameworks will be built that will reflect the comprehension of African-Americans’ cultural, sociological, and structural factors that drive the existence of heart conditions among them.
In addition, the differences in environmental exposures vis-à-vis the prevalence of cardiovascular diseases among this population will also be used to understand it. From the example, it becomes clear that epidemiology plays a significant role in understanding diseases at a higher level.

Sample Answer 4 for NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design
Reliability and validity are both used in research to design to assess how well a tests measure something. The two concepts are very closely related but they have some key differences that set them apart. I think validity is harder to understand and validity means that something measures what it is meant to measure (Learnosity, 2022). If the research, you are doing is designed to determine if a participant understands a set of principles that it can be valid if it is able to show the person does understand or who does not (Learnosity, 2022). An example of something being valid would be like the physical skills exams versus the theory exams when you take a basic life support class. You are tested on your physical skills as you must show the instructor you know how to do compressions and rescue breathes properly but at the end you also have to take a theory exam to validate that you understand basic life support and could perform it properly if needed before you are certified. Only doing one part would not validate that you understand. Reliability means that something is consistent and replicable (Learnosity, 2022). In other words, something that is reliable will have the same or similar results every single time its done. This may be a dumb example but if you do the same problem on the same calculator over and over again and it gives you the same answer that is a reliable calculator.
One of my article’s titled Central Line Care: Reducing Central Line – Associated Bloodstream Infections on a Hematologic Malignancy and Stem cell Transplant Unit used the method of administering a pretest to nurses and created an education al program based on their responses (Beaudry & ScottoDiMaso, 2020). The program was a two-hour class using different types of teaching, including standardized practices associated with central line care (Beaudry & ScottoDiMaso, 2020). They were then given a post-test after the program and a certain period of time. The scores from the pretest and post-test were analyzed. The program was effective in standardizing education and improving knowledge gaps, resulting in the reduction of CLABSI rates (Beaudry & ScottoDiMaso, 2020). Overall, the staff’s knowledge surrounding central line care and maintenance increased by 16% (Beaudry & ScottoDiMaso, 2020). No CLABSI events were reported on the unit from the time of program initiation. The validity of the results was okay because the clinical outcome and the outcome of the test showed an increase in knowledge, but I think the increase should have been more. I also think this it is reliable because it was the same nurses all throughout but as they increase their knowledge results will change and the program will change so it’s hard to say if it is reliable.
