Risk factors forpost-traumatic stress disorder symptoms following critical illnessrequiring mechanical ventilation: a prospective cohort study.Critical Care, 11(1), R28.http://doi.org/10.1186/cc5708

Typeof Quantitative Design

The explanatory research design was employed in conducting the study.The design seeks to offer an explanation regarding a particularphenomenon. Notably, the issue being explained is new and has notinitially been elaborated. For example, the researchers explain whyfemale patients and those on high doses of lorazepam are likely tosuffer from PTSD symptoms. Further, the article explains whymechanical ventilation was required for patients exhibiting PTSDsymptoms after a critical illness.

Evaluation of Design

The design is appropriate for conducting the research because of theinitial objective of the study. The explanatory research aims atestablishing the reason following a particular issue. The decision toemploy an explanatory research approach would be instrumental inenabling the researchers to achieve the goals that they have set.Further, it was essential that the research design adopted by theinvestigators is in line with the methodology employed. For example,the researcher`s follow-up patients exhibiting PTSD symptoms. Theresearchers assess different groups of patients in a bid to get adefinite explanation on the issue under investigation. Because of thesame, it was essential that they adopt a research design that befitsthe aim of the study. The particular design used dictates themethodology that is employed. The design selected by the researchersis efficient since it can be relied upon to achieve the aim of theresearch. The illustration of the factors for PTSD can beaccomplished by the adoption of a reliable approach by theresearchers.

Typeof Quantitative Design

The researchers employ the correlational quantitative researchdesign. In the study, the researchers focused on assessment of theprevalence of post-traumatic stress disorder symptoms after secondaryperitonitis. The ability to achieve the objectives of the study wouldbe preceded by the selection of an appropriate research design.Correlational research designs are characterized by the need toestablish a causal relationship between different factors. In thestudy, the researchers aim at determining whether there is a causalrelationship between surgical treatment for peritonitis and thedevelopment of PTSD symptoms. Indeed, the researchers were able todetermine that there is a higher chance of patients developing PTSDsymptoms after undergoing surgery.

Evaluationof the Design used

The choice of the design is appropriate considering the nature of thestudy. The focus of the study is to establish the presence of anycausal relationship. In their findings, it is evident that patientstreated for secondary peritonitis have a high likelihood ofdeveloping PTSD. The approach employed by the researchers qualifiesit as a correlational design since they monitor a group of patientswho have been treated for peritonitis and assess the prevalence ofPTSD symptoms.

Ramificationsof Choosing an Inappropriate Research Design

The research design dictates the methodology that would be employedby the researchers to get answers for the particular researchquestion. The choice of an inappropriate research design would meanthat they use a wrong methodology (Flick, 2015). The results of theirstudy may not be accurate because they employed the wrongmethodology. The correct procedures should be employed in conductingresearch. The ability to do so is dictated by the use of anappropriate design.
