If a nurse wants to study the effectiveness of an intervention like sending reminder calls to parents, public health support services, among children that needs immunization, what kind of study design other than quasi experimental cohort can be used and why. Based on that design, how will it answer the research question?© BrainMass Inc. brainmass.com October 10, 2019, 12:28 am ad1c9bdddf
We recognize that randomization is the gold standard in research, but sometimes it is almost impossible or difficult to establish the criteria for determining who will or will not be included. Quasi experimental designs give you the flexibility of not having to select the subjects because they are "naturally" randomized. In these studies, you include a comparison group, this will allow you to derive causal inference regarding the relationship between those who received the active intervention and their subsequent behavior. This design has become more accepted now a day for certain type of studies especially those who look to modify behavior with subjects in their natural environment.
To start you need to define better, what you hope to ...
Short discussion on the use of quasi experimental cohort and randomized cohort studies as possible study design that can prove effectiveness of sending reminders for inmunizations as an intervention. A possible case scenario for a randomized cohort study is given.
