Validity and Reliability
A key component of using evidence-based practices is to review the best available data from multiple sources to ensure that a quality decisions. (Barends, Rousseau, & Briner, 2014). To identify the best available data, one can begin by questioning the validity and reliability of a study. Validity and reliability in evidence-based research is essential to the success of a research paper. Validity is concerned with the extent to which the research measures what it designed or intended to measure. (McLeod, 2013). The validity of research relates to how valuable the research findings are to the question at hand (Leung, 2015). Validity in research is the work done that is credible and believable because those sources find

Researchers prove these three types of validity by having a set of measures that is valid. Content validity measures how well the collected data represents the research question (Cooper & Schindler, 2011, 281). Criterion-related validity determines how well a set of data can estimate either reality in the present or future (Cooper & Schindler, 2011, 281-282). The best suggested way to measure this is to “administer the instrument to a group that is known to exhibit the trait” (Key, 1997). Construct validity determines the success in the measurement tool of validating a theory (Cooper & Schindler, 2011, 282-283). There is another less common validity factor called face validity, which determines if “managers or others accept it as a valid indicator” (Parker, 2003). In addition to the three categories of validity explained above, there are two types of validity to consider internal and external. Flaws within the study, such as design flaws or data collection problems, affect internal validity. Other factors that can affect internal validity including the size of population, task sensitivity, and time given for data collection. External validity is the extent to which you can generalize your findings to another group or other contexts (Henrichsen, Smith, & Baker, 1997). An example of this is having a study done over only male football players. This study might not have the external validity for female gymnasts due to the specific domain of the

In reviewing this article, this writer was able critique the study and the suitability that it can possess if applied to actual practice. An important factor on whether a study can be considered valuable is if it is transferable in other situation, that is, a study's results should also be reflective if duplicated on other samples (Polit & Beck, 2006). Thus, the statistical power, internal and external validity are important to observe and note (Polit & Beck). If this writer were to carry out this study, it would have to be reflective of how the researcher performed it originality.
The Values and Motives Questionnaire, also known as the Values and Motives Inventory, is designed to examine a person’s motivation in relation to his values and activities. In order to ensure a comprehensive understanding of values, the VMQ assess three distinct areas, including: interpersonal, intrinsic, and extrinsic. Interpersonal values, according to the VMQ refer to one’s relationships with others. Intrinsic values contain one’s personal beliefs and attitudes. Finally, extrinsic values are one’s motivating factors at the workplace. Each of these three areas contain twelve topics
Evidence-based practice is an approach used by health care professionals to continually use current best evidence-based research to make ethical and reliable decisions regarding patient care. “Research to promote evidence-based practice is becoming more and more a part of the regular work of health care leaders” (Grand Canyon University, 2015, p. 1). However, it is important to determine the difference between solid research and flawed research that provides unreliable inferences. Evidence-based research includes focusing on a clinical question; and includes the review and incorporation of several studies to strengthen the results of the new study (Grand Canyon University, 2015). Roddy et al. and Ganz et al. articles will be assessed to determine if the recommended changes were backed by solid research that warrants changes in a hospital.
Validity refers to whether the research conducted is what it intended to be. Validity involves dependability, which means, a valid measure must be reliable. But, reliability doesn’t have to link to validity, a reliable measure is not required to be valid.
Why is internal consistency such an easy way to assess reliability from a methodological perspective?
During college, students should be able to research and analyze their sources. It is an important life skill. By using the ability to research, they can find articles with credible, reliable, and relevant information to get the best and dependable research. People who use these techniques will find each of these components essential to the authenticity of an article. These skills would be able to help students and researchers discover trustworthy and reliable sources. Each of the different components in a quality research makes it solid and dependable. Credibility is how believable or truthful the research, and whether the researchers have the credentials to do research in that area. Reliability is the reputation of the article’s source, and if the authors considered any biases. Relevancy is how current the article is or how important it is now. Students conducting research in college need to be able to critically analyze sources for credibility, relevancy, and reliability in order to determine their usefulness in a research paper.
The article’s researchers believed that it is necessary to research the efficacy of these claimed evidence based interventions.
Evidence-based practice is defined as the “integration of best current evidence with clinical expertise and patient or family preferences and values for the delivery of optimal health care” (Quality and Safety Education for Nurses, 2012). It is “the use of research in clinical decision making” (Brower, 2017).With the tremendous changes in the healthcare landscape, many processes have to be evaluated for its relevance, reliability,
In order to know whether the evidence of research studies are accurate, one must be able to have a fundamental understanding in statistical analyses to determine if such descriptions and findings within manuscripts and articles are presented correctly and explicitly (Sullivan, 2012). Proper use of statistics begins with the understanding of both descriptive and inferential statistics. Correct organization and description of data characteristics from the population sample being studied leads the researcher to identify a hypothesis and formulate inferences about such characteristics. It is with inferential statistics that researchers conduct appropriate tests of significance and determine whether to accept or reject the identified null
This rating scale is used to determine whether or not research is worth putting into practice. During the appraisal of research, there is a different level of evidence that is taking into consideration. There is three quality rating with five different categories. The quality rating is graded from high, good, and low or major flaw level of evidence. A high-quality research requires the study to be well structured and organized with all the necessary elements and definite conclusion. Research is considered good when the result is within normal limits and the conclusion although not conclusive can lead to more research. Lastly, a low-quality rating did not provide much information and stayed inconclusive (Dearholt.& Dang, 2012, p. 12P). There is five level of evidence in which research can fall under. The level is from I to V. the level I includes all systematic review researches that are experimental with a randomized controlled trial. These researches might be randomized with or without meta-analysis.
Literature reviews provide adequate supporting evidence for the evidence-based practice (EBP) process (Cowell, 2016). By using the information obtained from the literature review, that supports the topic, one can evaluate a situation and arrive at the problem that needs a solution. Therefore, an appropriate technique is necessary when searching for the right literature and evidence (Cowell, 2016).
Drawing on a range of evidence discuss how different types of research can be used to support practice.
Validity refers to that measuring tool or approaches can accurately measure things needed to be measured. It can be considered as an extent that measured results reflect investigative contents. Measured results more tend to be identical, validity will be higher, vice versa. Guba and Lincoln (1981) argued that whole social research must include invalidity in order to acquire worthwhile data within both the rationalistic paradigm (quantitative research) and naturalistic paradigm (qualitative research). Some factors can determine the level of validity, which include bias, construct
Evidence-based practice (EBP) offers a framework utilization of systematic high-quality research, an analysis which consistently enhances measurable client outcome and clinical decision-making grounded in rationality; EBP depends on data collected through experimental research and accounts for individual client characteristics and clinician expertise. The potential benefits of EBP comprise of increased service delivery and quality of care, heightened accountability, and a bridging of the research-practice gap (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000). It is imperative that research scholars are cognizant of research outcome dependability and validity prior to implementing results
