Post-Traumatic Stress Syndrome Essay

Brenner, Betthauser, Homaifar, Villarreal, Harwood, Staves, and Huggins (2011)

Brenner, Betthauser, Homaifar, Villarreal, Harwood, Staves, and Huggins (2011) used a quantitative study design in their investigation on post-traumatic stress disorder. The number of cases chosen by the researchers is N=81, whereas the number of controls is N=160. The survey results have been used to develop a study that confirms the association between posttraumatic stress disorder and suicide risk among the selected veterans engaged in the study.

The second study by Küen and Gallinat (2013)

The quantitative study design is used by the researchers in the second study by Küen and Gallinat (2013), with 319 subjects directly participated in the research. Additionally, the researchers bring in nine studies to investigate the reduction in the gray matter reduction amongst individuals going through the post-traumatic stress syndrome. Meta-analysis is used in running the quantitative variable that led to the establishment of the result that gray matter reduction was more prevalent amongst individuals with post-traumatic disorder patients compared to those without post-traumatic stress disorder. The standard feature in the two studies is that quantitative studies are used to being about the differential results in the control and experimental groups, thus, affirming the efficiency of the intervention method proposed.

Ramifications of choosing inappropriate research design

Ramifications of choosing inappropriate research design

Quantitative research has a critical emphasis on casual relationships, which can be established from the variables of the study. According to Polit & Beck (2012), the design that a researcher chooses to utilize in the study has a direct influence on the results that he or she gets from the research. Therefore, when a researcher chooses an inappropriate design, the results are highly likely to be inaccurate, calling doe a repeat of the entire research exercise. Scrutiny of a quantitative study needs to be done carefully to ensure that only the appropriate and relevant study design is utilized by a researcher.
