Unit 6: Critiquing Qualitative and Quantitative Research Kaplan University July 16, 2013 Unit 6 Critiquing Qualitative and Quantitative Research The research conducted by Foster-Fitzpatrick, Ortiz, Sibilano, Marcantonio and Braun (1999) is a quantitative study of the significance of crossing the legs while blood pressure is being measured. The purpose of the research was to determine whether leg-crossing impacted the results of blood pressure measurements. The research conducted by Palese, Skrap, Fachin, Visioli and Zannini (2008) is a qualitative study of the subjective data collected from patients who experienced while-awake craniotomies.

167). This study meets the criteria for purposeful sampling. Critique of Sampling Methodology Quantitative Critique of Sampling Methodology The convenience sampling that was used in recruiting all male patients who were on blood pressure medications is a glaring bias in this study. There was no information provided addressing why the patients were presenting to the clinic. There are many interventions that can raise blood pressure. For example, the study conducted by Marshall, Anantharachagan, Choudhary, Chue and Kaurhis, (2002) investigated the effect of situational anxiety on blood pressure experienced in anticipation of a blood test. Marshall, et. al., (2002) found that anticipation of a blood test can raise blood pressure. Foster-Fitzpatrick, et. al., 1999 did not address the purpose of the patient’s visit to the clinic. The researchers addressed known influential factors verbally, but not all factors were controlled during the experiment. For example, time of day, the white coat effect along with respirations and heart rate were not addressed in the results. Qualitative Critique of Sampling Methodology Based upon information provided this study was appropriate conducted as a purposeful sampling but, this study
The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is
The purpose of this paper is to critique a qualitative research article in all phases of the report. For this purpose, the article that will be used is “Lamentation and loss: expression of caring by contemporary surgical nurses” written by Carol Enns and David Gregory. This paper will address the problem statement, literature review, conceptual underpinnings and research questions, research design/method, ethical considerations, sampling, data collection, data analysis, confirmability of the findings, interpretation and discussion of findings, additional considerations, and rating the scientific merit of a research report.
The concern on whether anti-hypertensive’s should be withheld in patients who are hypertensive has been debatable in the recent past. Generally, the treatment of hypertension among hospitalized patients is basically an opportunity to enhance the recognition and treatment of blood pressure (Axon, Nietert & Egan, 2011, p.246). This is mainly because hypertension is a basic risk factor for heart diseases, stroke, and death whose impact is widespread to nearly 70 million adults in America. There have been numerous educational initiatives and publication of treatment processes to address this condition in the past few decades. Despite these measures, nearly 39 million Americans are at risk of hypertension because they have not reached their desired or optimal blood pressure.
provided to each participant. No participant was given the full intention of the study. This
Quantitative and qualitative research studies are both significant in nursing. In this paper, I will be critiquing two articles using both approaches. Using Walden’s database system, the articles will be located and compared to one another. After this assignment, I hope to gain a better understanding if critiquing research articles.
The qualitative article being appraised is by Martin and Woods (2012) using the CASP tool qualitative framework (CASP 2013). These tools have been validated to ensure that studies can be assessed in a consistent way assessing the trustworthiness of the research article (Aveyard, 2014)
Nurses are required to base their practice on evidence-based research. Therefore, it is essential for nurses to develop the skills necessary to analyze a research article. Critiquing a research article helps nurse judge the creditability of the information presented. This essay reviews a qualitative study titled “Factors Associated With Aggressive Behavior Among Nursing Home Residents With Dementia.”
10) Was the sample for this study adequately described? Provide a rationale for your answer
Described below is a critical appraisal of a qualitative article by Lisa Booth using the frame-work suggested by Ryan, Coughlan and Cronin 2007 to establish its believability, robustness, credibility and integrity (Ryan, Coughlan & Cronin, 2007).
Through the Nursing and Midwifery Council (NMC) code of professional conduct (NMC, 2004) nurses supply high standards of care to patients and clients. One code nurses adhere to is clause 6 which pronounces nurses must maintain professional knowledge and competence, have a responsibility to deliver care based on current evidence, best practice and validated research (NMC, 2004). Validated research involves critiquing and acquiring the skills of synthesis and critical analysis, this enables nurses to distinguish the relationship between theory and practice in nursing (Hendry & Farley 1998).
Yes. In the article, the aim of the research was to understand the experience of participants, their knowledge about type 2 diabetes, and the factors of medication adherence in Malaysia. According to Susan (2010), the five components of PICOT are population, issue, context, outcome, and time. According to Al-Qazaz et al (2011), the PICOT was presented by the researcher in the study were,
e. I did not recognize any potential bias introduced by the sampling method used. The researcher states the eligible requirements to participate in the study and the results reveal the significance of the use the patients and the effectiveness.
The purpose of the experiment is to see how different variables affect pulse rate and blood pressure.
We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use.
Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important.
