Understanding the RCT Steps Sequence
This section details the correct order for the key steps involved in conducting a Randomized Controlled Trial (RCT), as presented in the question.
Correct Sequence of RCT Steps
- C. Select suitable sample
- B. Select suitable population (reference or target population)
- A. Make necessary exclusions
- D. Randomize to form experimental group and control group
- E. Manipulate, follow-up and assessment
Explanation of RCT Steps
The sequence begins with defining the study participants and progresses through randomization to the final assessment.
- C. Select suitable sample: Initially, identify and recruit a specific group of participants who will be involved in the trial.
- B. Select suitable population: Define the broader group (reference or target population) to which the study findings are intended to apply. This step clarifies the generalizability context.
- A. Make necessary exclusions: Apply specific criteria to remove individuals from the selected sample who do not meet the trial's requirements or could confound the results.
- D. Randomize to form experimental group and control group: After defining the final sample, participants are randomly assigned to either the intervention (experimental) group or the non-intervention (control) group to minimize bias.
- E. Manipulate, follow-up and assessment: The experimental group receives the intervention (manipulation), and both groups are monitored (follow-up) and assessed over time to measure outcomes.
