Quantitative Research Design Critique Template

The “Quantitative studies usually focus on concepts that are fairly well developed, about which there is an existing body of evidence, and for which there are reliable methods of measurement” (Polit and Beck, 2012). I chose the Quantitative method of data collection for my research because I want to determine the effectiveness of multifactorial intervention in increasing treatment adherence in patients with Chronic Obstructive Pulmonary disease. I believe that face-to-face training, audio-visual material, return demonstration, and follow-up on inhalation techniques will increase patient’s treatment adherence and better health outcome.

1. What type of question (therapy, prognosis, …show more content…
What would be the strongest design for the research question? How does this compare to the design actually used?

The strongest design of this study would be experimental. Randomised controlled trial is necessary for this design to determine whether the variables will affect outcomes. Control group would be necessary to compare with the intervention group. With this design I would be able to determine how multi-factorial interventions increased treatment adherence. The patients who are diagnosed with COPD in our long term care unit will be divided into two groups using the randomisation techniques. Treatment adherence would be determined by the percentage of COPD patients classified as good adherent.

3. Is there an intervention or treatment? Was the intervention adequately described? Was the control or comparison condition adequately described? Was an experimental or quasi-experimental design used?

There would be no treatment needed for the study. The subjects were randomly assigned to a control group and an intervention group. The multi-factorial interventions in the study were adequately and clearly described to determine their effectiveness on treatment adherence. An experimental design was used to find out if outcomes were different in two …show more content…
The control group received no interventions while the intervention group received the multi-factorial intervention to improve adherence to prescribed treatment. The design of this study would determine the effectiveness of multi-factorial intervention on treatment adherence in COPD patients.

8. Was the study longitudinal? Was the timing of the collection of data appropriate? Was the number of data collection points reasonable?

The study would be longitudinal, because I would gather my data on the same patients repeatedly over 6 months. The participants in the study would have the same number of follow-up visits. I would make my three follow-up visits on the control group and intervention group at two, four, and six months.

9. Was blinding/masking used? If yes, who was blinded—and was this adequate? If not, is there an adequate rationale for failure to mask? Is the intervention a type that could raise expectations that in and of themselves could alter the
