HCA 699 Reliability and validity are related qualities but independent

Topic 5 DQ 1

Reliability and validity are related qualities but independent. They are similar to the terms “precision” and “accuracy,” respectively. A wind-up clock that does not work is accurate (valid) twice a day. But it lacks precision (reliability). A digital clock that is always 5 minutes slow is never accurate (valid) but is very precise (reliable). Elaborate on the assessment instrument used in your project to ensure validity and reliability.

Re: Topic 5 DQ 1

Reliability and Validity are important factors in all research, with qualities that are similar but also independent of each other. The purpose of research is to understand then prove or disprove a theory. In order to do that, data that is reliable and valid must be found. The literature review performed to answer my question for this project contained both quantitative and qualitative data analysis and methods. There were different assessment instruments used as they all provided keen information into the problem and proposed solution.

Observation is one instrument that is useful when setting a baseline for the data and the outcomes that will be measured for validity and reliability. There were two types of observation studies included in the research and will be used to set the baseline for answering the question if training staff on infection control will reduce the risk of elderly residents contracting an infection in long-term facilities. Observation studies can be both quantitative and qualitative approaches to data (Makris, A., Morgan, L., Gaber, D.J., Richter, A. & Rubino, J.R, 2004).

Randomization Controlled Trials is the second assessment instrument used for the purpose of this project study. The findings from the two controlled trials are quantitative and will provide the basis for understanding reliability and validity in repeating the steps both internally and externally in other environments (Temime, L., Cohen, N., Ait-Bouziad, K., Denormandie, P., Dab, W. & Mounia, H., 2017).

Surveys are another instrument used in this research and were key in understanding the beliefs of staff and other personnel on the importance of hand hygiene for infection control. Surveys can be both quantitative and qualitative, if the survey questions are designed to get valid information on the phenomena of attitudes, and the number of participants who believe in the same methods or things (Kaur, J., Stone, P. W., Travers, J. L., Cohen, C. C., & Herzig, C. T. A., 2017).

This is a succinct and a great discussion, it shows that you understand the ideas of reliability and validity as applied in the research studies. The two concepts are critical in the research processes as they enhance confidence and self-reliance on the research outcomes (Ruel et al., 2015). In most cases, both the qualitative and quantitative studies have to test the formulated hypothesis and answer the research questions highlighted. To achieve the above objectives, the studies should always be valid and reliable. Concisely, reliability and validity of the research outcomes depend on the methodology applied in processes of the studies (Ruel et al., 2015). From your discussion, it is true that observation is one aspect that is critical when it comes to setting the baseline for the outcomes and data that are supposed to be measured for reliability and validity. The randomization control trials and surveys are also some of the essential approaches that may enhance conciseness or validity and reliability of the research outcomes.
