Discussion: Quantitative Research Designs
In order to find the best information on a topic, not only should you develop a question and search for resources, but you should also know how to analyze the value of the resources that you identify. There are different ways to evaluate resources, such as using the hierarchy of evidence, which you explored in Week 4 of this course. Another way to evaluate resources is to consider the appropriateness of the research design. Understanding how research designs contribute to the quality of a study is essential for being able to analyze resources when conducting a literature review or locating evidence for practice.
In this Discussion, you consider the different research designs and evaluate how these designs have been used to research a specific topic. You also consider strategies for selecting an appropriate research design.
To prepare:
Review the information in the course texton quantitative research designs. Focus on the information in Box 9.1, “Guidelines for Critiquing Research Designs in Quantitative Studies” located on page 210 of the course text.
Select a topic from the list below and search the Walden Library to find two different quantitative research studies addressing that issue:
Caregiver stress
Anxiety in children
Sleep apnea
Depression in college freshmen
Rural health care issues
Post-traumatic stress syndrome
Traumatic brain injury in veterans
Health effects of environmental contaminants
Bipolar disorder
End-of-life ethical issues
Alternative medicine
For each of the sources that you select, identify the type of quantitative research design used, and evaluate whether it is the most appropriate approach to the research.
Consider the ramifications of choosing an inappropriate design for a research study.
By Day 3
Post the topic you selected, references for the two sources you identified, and the quantitative research design used in each. Critique the appropriateness of the design used and justify your comments with information from the Learning Resources. Discuss the ramifications of choosing an inappropriate design for a research study.

Answer
Article Critique
A good research paper depends on the quality and reliability of the resources used. A perfect research topic which covers current problem in the society can be of no importance when wrong resources are used to complete it. It is in this context that it is important to use not only latest resources but accurate ones which specifically address the problem or the topic in question. Some of the factors to consider while choosing resources include reliability, hierarchy of evidence, publication date as some are outdated, and research designs among other factors (Nilson, 2016). Focusing on anxiety in children as the topic, this essay identifies to articles and evaluate how research designs have been used and their appropriateness in the chosen resources.
Sciberras, E., Lycett, K., Efron, D., Mensah, F., Gerner, B., & Hiscock, H. (2014). Anxiety in children with attention-deficit/hyperactivity disorder. Pediatrics, 133(5), 801-808.
This resource examines the effect of anxiety on the development of children. It also highlights relationship between attention-deficit/hyperactivity disorder (ADHD) and anxiety among the adolescents. The type of qualitative research design that has been used by Sciberras et al., (2014) is ethnographic design. This is a qualitative method where researchers interact with observe a study’s participants in their real-life environment. from the results, I can ascertain that ethnography research design was the best in this case because of its ability to deliver a faithful and detailed representation of users’ behaviors and attitudes. As such, ethnographic research design is the most suitable in this research since it has assisted to answer the research question. Notably ethnographic design is subjective in nature and is very important in analyzing and uncovering relevant user emotions and attitudes. while ethnographic design was the best choice for the authors, I feel it takes a lot of time which may give wrong results to what causes anxiety among children since as children grow certain things such as family income, school, and environment which change and might have affect the outcome before the study ends.
Bhatia, M. S., & Gautam, P. (2016). Case report of a child’s anxiety disorder precipitated by tremors from a distant earthquake that was extensively covered in local news stories. Shanghai archives of psychiatry, 28(1), 52.
The article is about the case of a 10-year-old female who went psychiatric outpatient unit with a 3-week symptoms of austere, disabling anxiety indications caused by non-destructive shocks from a distant earthquake. The article seeks to answer some of the causes of anxiety among children. Bhatia and Gautam (2016) use case study research design to answer the research questions. While case study gives time and space to build a detailed understanding of the topic, it is the wrong choice to answer the research questions presented in this case. However, if the researcher had to utilize case studies then I think he would have brought forward more than one participant who was affected by the same tremor so they could make a comparison on whether or not the earthquake contributed to the anxiety symptoms experienced by the participants. In this case, it would be inappropriate to conclude that earthquake or other natural calamities caused anxiety when only one child was used in the study. The research design chosen in this article therefore does not help to answer the research may mislead the readers or future researchers.
