Document Summary
Identifying the best research design to fit the question: quantitative research. Questions about the effectiveness of prevention and interventions. The random allocation of participants to groups, which helps to ensure that groups are similar in all respects except exposure to the intervention. The longitudinal nature of the study, whereby exposure to the intervention precedes the development of the outcome: disadvantages. Long period of follow-up before patients experience the outcome. Possibility that patients who agree to participate in a trial may differ from those to whom the results would be applied (generalizability) Questions about the cause of a health problem or disease. Rct: participants are randomly allocated to be or not to be exposed to a potential causative agent and then followed up to compare the number in each group who experience the outcome. Rct or cohort analytic studies may be feasible.
