Recommended: issues with validity and reliability
This paper will discuss several different aspects of using evidence research. It will compare and contrast validity vs. reliability and address wither it is possible to have an instrument that is valid and not reliable. It will also examine type I and type II errors as well as examine the differences between parametric and non-parametric. Lastly, this paper will look probability and what the minimum level of significance is for a research paper. Validity is essentially the degree to which a conception is founded and parallels accurately to the real world. Validity is the tool that measures what the particular research was anticipated to measure (Schmitt & Brown, 2012). There are several different types of validity but the ones that will be discussed in this paper are concurrent and predictive. Concurrent validity is taking an already validated point and testing it with another measurement tool. This means that there was already a hypothesis proven right or wrong and now the researcher will be testing this same hypothesis but will being using another type of tool to see if the result...
If they decide that there is ample material on the specific topic at hand, the team moves on to the next phase of the Iowa model. If sufficient amounts of research do not exist on the subject, a research study may need to be carried out (Brown, 2014). This stage also consists of the research team evaluating the rigor of the research that they have collected (Doody & Doody, 2011). It is important to have an analysis procedure in place for all members of the research team to follow when evaluating research studies to ensure consistency in the appraisal of the quality and precision of each research study found (Doody & Doody, 2011). According to Doody & Doody (2011), “effectiveness, appropriateness, and feasibility” (p. 663) are three of the grading standards that researchers can use in evaluating research studies.
...g the criteria noted above in the checklists proved in Houser (2015). It has been noted with evaluation that it appears to have the components of adequate criteria for being a credible source and having credible authors. The design of being a qualitative study has been evaluated and contains most of the components of the noted checklist. There are ethical issues that are well documented and weighed. The problem statement and purpose statement have been noted and the literature review was evaluated thoroughly. The sampling strategy is purposeful and explained in depth. The study was compared and is noted that its methods are of trustworthy quality. To optimize EBP is the ultimate goal in conducting a study of this nature. It has been shown that there is a significant amount of knowledge obtained from the study and there is a probable use for this information.
Evidence –Based Practice is a process through which scientific evidence is identified, appraised, and applied in health care interventions. This practice obliges nursing experts to depend on logical research and confirmation more frequently than experience or instinct. EBP is intended to guide medicine of patients in a regulated methodology. This model joins together research, investigation and patient history to give the most exhaustive consideration conceivable. EBP got mainstream throughout the late 1970s. In any case, the thoughts behind the practice were presented much sooner than by nursing pioneer Florence Nightingale. As stated by Carole Cooper, "Nightingale evaluated nature's turf, gathered information, distinguished intercessions and observed patient results." This methodology mirrors current evidence- based practice. Utilization of EBP expanded throughout the 1970s and 1980s in light of calls for additional productivity in patient consideration. While restorative exploration discoveries were accessible, specialists and attendants were not equipped to get to or execute the new data rapidly enough. This new system joined together components of useful information and experience with clinical examination discoveries and investigation.
In social work evidence based practice is considered to be a decision making process and practitioners rely on the evidence when working with clients. According to Aveyard and Sharp (2013), evidence based practice is not easy to put into practice and there are many barriers to evidence based practice such as lack of time, lack of awareness of research, lack of support and cooperation, and lack of authority and inadequate facilities (p. 145). Although there are challenges to implementing evidence base practice this is still a doable task in the field of social work. Therefore, practitioners need to explore the motivation, knowledge and skills needed by the individual, the organizational motivation, learning
...the data did not involve member checking thus reducing its robustness and enable to exclude researcher’s bias. Although a constant comparative method was evident in the discussion which improved the plausibility of the final findings. Themes identified were well corroborated but not declared was anytime a point of theoretical saturation Thus, the published report was found to be particularly strong in the area of believability and dependability; less strong in the area of transferability; and is weak in the area of credibility and confirmability, although, editorial limitations can be a barrier in providing a detailed account (Craig & Smyth, 2007; Ryan, Coughlan, & Cronin, 2007).
However, both characteristics of reliability and validity are important and can be used in many studies, such as the self-rating and other- ratings of daily behavior. Reliability refers to the internal consistency, inter-rater reliability, test-retest, and standardized scoring. In other words reliability means that study scores have to be constant with repeatability of the findings. Validity also refers to convergent validity, discriminant validity, and predictive validity. Validity refers to the reliability or credibility of the research. If the findings in a study, reliability and validity are valid they must be reliable.
Different styles of research are employed in research to safeguard that the facts are acquired to permit examiners to find resolution to the principal queries for the study correctly, therefore, evading uncertainty ( ). Acquiring relevant proof encompasses stipulating the type of proof mandatory in answering the query. Methodological designs encompass logical complications; therefore, matters of sampling, information gathering methods, and queries are secondary to the type of method used in research. Strategies are often compared with quantitative and qualitative research methods. Research and collective studies are often observed as principal specimens of quantitative research and are evaluated compared to the flaws and strong point of numerical, examination, and quantitative research methods ( ).
In the article “Using Evidence-Based Practice to Reduce Catheter-Associated Urinary Tract Infections”, by AJN, the author states how catheters are causing urinary tract infections among adult patients in healthcare facilities. The purpose of healthcare workers reading the article, “Using Evidence-Based Practice to Reduce Catheter-Associated Urinary Tract Infections”, is to provide better care to their patients with a Foley catheter and to try and prevent a urinary tract infection associated with a Foley catheter. This article affects the nursing process by presenting it with further education, and affects the patients by giving them a better catheter experience.
First, I will start with the question I have about validity evidence, explain, and give an example of response processes? Now that I have ask the question, I will move onto the key points that I believe relate to validity. The first and I believe
Case Management is to provide support to patients by making sure that they are getting the optimal care. Utilization Management is to maintain the quality of healthcare by ensuring the least costly but most effective treatment plan. However, both Utilization Management & Case Management are working together to prevent unnecessary treatment, duplication of services, long Stay (LOS) in hospital. Evidence Based Practice exists to demonstrate the value of case management and Utilization Management in order to enhance patient-centered care. The call for evidence-based in healthcare make patient’s effective, safe, and efficient. Case management use a team approach such as physicians, nurses, nutritionists, therapies and treatment to improve best
Evidence based practice (EBP) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research" (Sackett et al, 1996). This definition takes into consideration the need to delve into the professional’s clinical knowledge (Burns, 2007) as well as looking into the best evidence to support the professional. Clinical practices may become out dated if new evidence is not sourced and professionals should be aware of appropriate evidence that can be integrated into their practice (Aveyard & Sharp, 2013). EBP is important
This paper aimed to critically analyse why nursing care of patients depends upon evidence base research and is less dependent on ‘opinion’ and ‘ritual base’. It explores health care professionals in the field of health in order to define and aspect of the emergency and purpose of evidence-based nursing care provision. It also explains the importance of evidence-based practice in the provision of quality nursing care for patients and carers. Furthermore, the comparisons grew due to increasing healthcare treatment and expenditures. Use of evidence- based nursing is preferred over rituals or opinions in order to provide the best quality treatment (Stevens, 2013). On the other hand, procedures that were designed in the past and has been
One of the pros of evidence based practice is its proven to offer favorable outcome. The findings in research and other discipline has guided health care professionals to make solid decision to improve patient care. Many health insurance companies depend of the evidence to dispense coverage for patients when a treatment has proven effective in a similar process. treatment for any ailment is based on facts rather than traditional methods and is backed by firm knowledge of the methods usefulness. Patient overall outcome is favorable due to the combination of observations made by healthcare professional, the feedback from patients, coupled with research and scientific
The use of evidence-base practice (EBP) has steadily grown over the past thirty years, but some hospital systems struggle with politics and organizational cultures that avoid change. It is important for health care leaders to remove barriers and provide an organizational framework of support to promote the use of best practices (Huber, 2014-a). In this post, I will discuss how infrastructure and culture affect implementing evidence-base practice and discuss the how evidence-base practice changes occur in my organization.
Although a hierarchy of evidence is argued by many policymakers and researchers alike, others argue that no one method of research is automatically any better than any...
