Discussion post due: Review of research questions Question one Research Design: Randomized controlled trialsStrengths: The research design is used to answer questions of effectiveness and efficiency of an intervention technique. This is because the design gives confidence in determining cause and effect. Also, it has a minimal chance of bias since exclusion and inclusion criteria are employed to choose participants, hence a homogeneous research population (Melnyk & Fineout-Overholt, 2011). Weaknesses: There is a possibility of a misleading answer that results in a false negative result.

This happens in a situation where the trial is too small to discover a true benefit (Bulpitt, 2012).Rationale: a randomized controlled trials design is appropriate since the objective is to evaluate whether the utilization of soap and water or alcohol-based rubs are more effective in preventing nosocomial infections. An experimental treatment group is compared with a control group, normal degree of care or placebo (Melnyk & Fineout-Overholt, 2011). Question twoResearch Design: Longitudinal comparative design (Cohort)Strengths: The design permits a researcher to evaluate the prevalence of a problem over a period and the reasons for probable changes in the variables of a research.

Weaknesses: The problem of this design is that there is a possibility of subject loss to follow-up because of various reasons that may result in unintentional sample bias (LoBiondo-Wood & Haber, 2014).Rationale: The aim of the research is to establish the connection between alcohol and breast cancer and the design concentrates on one illustration of the topic that is being studied. Question threeResearch Design: Cross-sectional studies.Strengths: The design gives prevalence estimates and descriptive data.

In addition, it is ethically safe (Lymn, 2010). Weaknesses: the limitation when using this technique is that non-response may result in biased outcomes. Rationale: cross-sectional studies is the appropriate design because it is used to establish current beliefs, behaviors, characteristics, attitudes, values and opinions of a specific population. The aim of this research is to find out the difference in attitudes of female and male college students about condoms. ReferencesBulpitt, C. (2012).
