NUR 550 Topic 4 DQ 1 Distinguish between reliability and validity in research design
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. 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. 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. You can ensure the data is correct and your participation in our EBP project will be effective by analyzing the evidence you chose to include in a study using the definitions of reliability and validity.

Studies or research should go through a critical appraisal process in which the study is 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).
As I mentioned in the article about effective 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.

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. 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.

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).
