The assignment deals with the review of the quantitative research article, “Self?weighing and simple dietary advice for overweight and obese pregnant women to reduce obstetric complications without impact on quality of life: a randomised controlled trial” by McCarthy et al. (2016). In response to the article, different elements of the research paper are described.
Quantitative research can be defined as systemic and objective process of using the numeric data to obtain information on particular domain of interest, describe the variables explain the cause and effect relationship between the variables (Creswell, 2013). Quantitative research is based business deductive logic that starts with hypothesis and collection of data to evaluate the hypothesis. The data is collected to identify the empirical evidence based on the topic.
Research methodology can be defined as the scientific method of conducting research to solve a problem systematically involving the use of different criteria and methods to research. Methodology simply refers to way of solving the problem (Creswell, 2013).
In the quantitative paper by McCarthy et al. (2016), randomised controlled trial was chosen as research design in the “Australian tertiary obstetric hospital. The chosen quantitative research article is based on the health issue obesity and deals with the overweight and obese pregnant women. The methodology used in this study is the randomisation of the participants, which in this case is women. The participants in the intervention group are targeted to simple dietary advice and serial self-weighing. Those in the control group are targeted to standard antenatal care. The participants chosen were women with singleton pregnancy who are overweight or obese non-diabetic. The sample size was 382. The inclusion criteria were selecting pregnant women who are less than 20 weeks gestation. The overall methodology appeared to be well designed to determine the obstetric outcomes of dietary advice to pregnant and obese women when compared to the standard antenatal care.
Ethics of the study
Research ethics can be defined as issues that are arising when human beings are involved in any research as participants and involves considering the ethical, political, social and legal issues (Faden et al., 2013). In the chosen article, the author has obtained the ethics approval from the “Mercy Healthcare Board Human Research Ethics Committee R10/16” in 2010 (McCarthy et al., 2016). It was ensured by the author that the participant’s health and quality of life is not hampered due to the intervention. The participants were recruited through written informed consent and the research midwife gave the relevant information to them. Only English speaking women were considered to avoid the language barrier.
Research findings and results can be defined as the outcomes of the research being conducted followed by its analysis and interpretations (Mertens, 2014). The results of the quantitative paper showed that the obstetric complications could not be prevented by the intervention designed by the author. There was no difference found between the intervention and the control group in regards to the mean gestational weight gain, CRP levels, adiponectin, and leptin. The results were statically evaluated (McCarthy et al., 2016).
The assignment was helpful in developing deep insights of quantitative research paradigm. It improved the experience of searching the literature to extract the required journal article. The assignment was useful in understanding the concept of randomised control trial and significance of research ethics.
