NUR 550 Discussion: Reliability and Validity in Translational Research

NUR 550 Discussion Reliability and Validity in Translational Research

Reliability and validity are critical concepts used in evaluation of research quality. these concepts indicate or illustrate how well a method, technique or test measures a variable. Reliability entails consistency on the measure. Reliability tells about the degree to which results can be reproduced when research is repeated under similar conditions by checking the consistency of the outcomes across time, different observers and parts of the test itself. Reliability implores researchers to ensure that their outcomes should be consistent across different parameters as assessed by various measures and individuals (Moon, 2019). On its part, validity is about accuracy of a measure used in research and shows the extent to which the outcomes really measure what they should measure. Validity attains its purpose by checking how well the outcomes align with established frameworks, theories and best practices in clinical settings. For instance, if a research study has high validity, it implies that it produces results that align with real features, variations and characteristics in the physical or social world.

The two concepts have a relationship. A reliable measurement may not be a valid measure as the results might be reproducible but not necessarily correct. However, a valid measurement is mostly reliable since an accurate test produces an accurate result and they can be reproducible. Reliability and validity relate to translational research as they demonstrate the accuracy and consistency in the results or findings. They also demonstrate that the outcomes can be assessed and comply with existing frameworks and theoretical models (Trautman et al., 2018). The two concepts illustrate the need for researchers to demonstrate consistency and accuracy in their findings. Translational researchers also rely on the two concepts to improve acceptability of their findings.

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.

Hello

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. 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.

Re: Topic 4 DQ 1

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).
