Research Questions & Designs

Is the use of soap and water or alcohol-based rubs more effective in preventing nosocomial infections?

For this research question, I would utilize an experimental design. Experimental designs are a definite way to illustrate a cause-and-effect relationship between variables (Gray et. Al, 2017). What this research question attempts to discover is which method of hand washing is most effective, therefor a pretest-posttest control group design is most appropriate. The results of using soap and water with one control group, can be compared to the results of the other using alcohol-based rubs. It would also be beneficial to have a control group that used neither, for most accurate results (Gray et. Al, 2017). An experimental study allows the researcher for tight control of subjects and variables; however, a significant weakness may be that the participants are aware of study, which can cause alterations in behaviour that skew results (Walker, 2005).

How effective are anti-depressive medications on anxiety and depression?

            A type of experimental design would work best for this question as well, possibly a nested design. Our text states that in a nested design, groups of subjects are assigned randomly versus as single subjects (Gray et. Al, 2017). This helps in attaining accurate results so that subjects are not aware of who is in what group, also there is the idea that in the clinical world protocols will need to be different among different groups (Gray et. Al, 2017).  Our text also states that in nest designs it is recommended to use larger groups versus smaller groups, as to diminish potential for extraneous variables (Gray et. Al, 2017). The rationale behind this suggestion is that people, or subjects, in these circumstances can feed off each other. There is potential for alteration in thoughts and behaviors based upon other peoples results or interactions, and that is something I would want to minimize as best possible.

What is the difference in attitudes of male and female college students toward condoms?

            The best study design for this topic, in my opinion, would be comparative-descriptive. This type of research design compares the relation among two or more groups (Gray et. Al, 2017). This could very easily be accomplished through a survey of some sorts, either online and anonymous or in person. Results from both men and women could be combined and compared and analyzed for differences. A downside to electronic surveys is that you run the potential of possible dishonesty of gender, as well as remembering that different people have different opinions of what gender is and who identifies as what gender. However, a simple survey does seem like the most simple way to capture information in this particular research question.
