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.

Critical review should be applied to studies and research to determine their utility, dependability, and validity (Melnyk & Fineout-Overholt, 2019). The ability to replicate similar results and the evaluation of intervention efficacy define a study design’s dependability. The correctness of the study as well as the accuracy of the measuring techniques used are used to confirm the validity of a research study.

NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

The degree of validity is determined by how closely the findings correspond to reality and whether the researchers used the most effective research methodologies (Melnyk & Fineout-Overholt, 2019).

The dependability of this study is easily replicable in any facility, as demonstrated in the paper I used on the effective deployment of QBL. The intervention was a success in that it demonstrated that using QBL rather than EBL was more beneficial in terms of raising awareness and tracking blood loss. While QBL was very effective in the early diagnosis and treatment of PPH, it was not more effective than EBL, according to the findings.NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

This study also demonstrated that by simply repeating the process, the same results could be obtained. According to the study’s validity, the subjects were chosen at random using a criterion that took into account moms with similar demographics (Coviello et al., 2019). The results were compared before and after deployment using high-quality data that can be measured, accurate, and validated.

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.

NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design. 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).

As I mentioned in the article about effective QBL implementation, the reliability of this study could easily be replicated in any facility. The intervention was successful in demonstrating that using QBL instead of EBL was effective in increasing blood loss awareness and monitoring. The findings did not indicate that QBL was more effective than EBL in the early detection and treatment of PPH. This study also revealed that this process can be replicated and yield comparable results.

According to the study’s validity, the subjects were chosen at random using a criterion of similar maternal demographics (Coviello et al., 2019). Using high-quality data that is measurable, accurate, and verifiable, the results were compared before and after implantation. Using the definitions of reliability and validity can assist you in evaluating the evidence you use in a study to ensure the data is correct and you will succeed in our EBP project.

Hello,

This is extremely insightful. The validity, reliability, and applicability of studies or research should be evaluated during the critical appraisal process. The terms validity and reliability are used to evaluate the quality of research processes (Keogh et al., 2019). The two approaches indicate how well a technique, method, or statistical test measures the subject under investigation during the research process.NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

The accuracy of a statistical measure is more important than its validity, whereas the consistency of a given measure is more important. The degree to which statistical results can be replicated if the research is repeated under similar conditions is also known as reliability (Coviello et al., 2019). The extent to which the study results measure what they are expected to measure is known as validity (Rose & Johnson, 2020). Validity can also be used to assess how well the results match previously established theories as well as other measures within the same concept.

Re: Topic 4 DQ 1 NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

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.

NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design 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.

NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design. 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).

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.NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

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.NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design

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.

NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design 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.

Reliability is the stability of measurement over time (O’Mathuna & Fineout-Overholt, 2019). For example, a scale will perform consistently over the course of a year. Sometimes, instruments like a scale will need to be recalibrated to remain reliable.

Validity is when an instrument measures what it claims to measure (O’Mathuna & Fineout-Overholt, 2019). O’Mathuna and Fineout-Overholt use the example of a scale that claims to measure fear would be invalid if it was discovered that it was really measuring anxiety (2019).

Mascret, et al. studied older adults on their acceptance level of a virtual reality headset to determine if this type of technology could be useful in fall prevention. A link for the study is here: https://www.jmir.org/2020/12/e20691/ . The study sample included 271 men and women over the age of 65 who were able to walk independently and had never used the virtual reality headset before. They were given information about the headset. Researchers questioned perceived usefulness, ease of use, and enjoyment using a Likert scale of 1 (strongly disagree) to 5 (strongly agree). This scale is valid as it tests the participants’ opinions toward the device.

It may lack reliability as participants may be inclined to give a higher score to appear accepting of technologies (Mascret, et al., 2020). The researchers tested reliability using McDonald omegas, a statistical technique that checks reliability. Participants were also asked to rate their confidence to perform daily tasks without falling and physical activity goals toward fall prevention using similar scales. Participants were found to have less acceptance of the device if they were more confident in daily activities. Participants who had personal goals toward increased physical ability were more likely to accept the headset. All results were self-reported, but the scales remained consistent throughout the testing.

When performing research studies, especially translational research studies, it is important to conduct the study in a way that it reveals results that are both accurate to the situation being studied and that the results are consistent when applied in similar situations. Reliability and validity are used to determine if a research study and its measurement methods meet these qualifications. Validity refers to how precise the measurements are, and reliability refers to how consistent they are. (Bachelor Print, n.d.)

The resilience scale (RS) that was one of the instruments used in the study performed by Schultz et al (2022) was validated in 1993 by being translated into Portuguese and found to be reliable when used in a cross-cultural resilience research study. The research study shows high construct validity because there is a strong relationship between elements such as, having high control over work environment and high social support being associated with resilience, which may lead to decreased occupational stress exposure elements and increased resilience (Schultz, et al. 2022).
