Randomized Controlled Trial or RCT: Learn the Basics
Clinical Interventions in Randomized Controlled Trial
One of the clinical inventions includes the standard of control or comparison. Here, the control can be a placebo, a standard activity or it can be zero intervention. A person who participates in such a study is known as the subject or the participant. Randomized controlled trial aims to evaluate and contrast the results once the participants get the interventions. Due to the fact the results are measures, this trial is counted as a quantitative study.
Features of Randomized Controlled Trial
- Randomized controlled trials are actually the comparative, quantitative and controlled studies where the researchers observe two or more than two interventions for a range of participants who get them in a randomized manner.
- This trial is taken as amongst the easiest and strongest techniques when it comes to clinical research.
- In this study the participants are allocated to a particular study group which is also known as a treatment condition or a study arm.
- In Randomized controlled trials the participants are allocated to study arms in a random way which means that they have equal chances of getting allocated to each group.
- Process in this study is controlled to make sure that every participant in the study arm is treated in the same way apart from the element that distinguishes every group from the other.
- This distinguishing element is the kind of intervention that they get.
Aim of Conducting a Randomized Controlled Trial
The main aim of conducting a Randomized controlled trial is to examine if the intervention functions by making a comparison of it to the control condition, mostly an alternative intervention or no intervention. Other reasons for carrying out an RCT are:
- To find out the elements that impacts the effects of intervention for example moderators.
- To comprehend the procedures from which an intervention impacts change. For example change mechanisms or mediators which result in the intervention effect.
Main Elements of a Randomized Controlled Trial
Following are the main elements of an Randomized controlled trial:
- The first methodological compound of an RCT is the need to make use of control condition in order to compare it with an experimental intervention.
- The second element of an RCT is the random allocation of the participants to specific conditions to which they are subjected to.
