Intervention study

Intervention Study is a type of research study that is often used in the field of medicine and public health. It involves the researcher intervening in the natural course of events to observe the outcome of the intervention.

Overview[edit | edit source]

An Intervention Study is a study where the researchers create a change or 'intervention' in the participants' environment and then measure the effect of that change. This type of study is often used in medicine and public health to test the effectiveness of new treatments or prevention strategies.

Types of Intervention Studies[edit | edit source]

There are two main types of intervention studies: Randomized Controlled Trials (RCTs) and Non-Randomized Controlled Trials (NRCTs).

Randomized Controlled Trials[edit | edit source]

In a Randomized Controlled Trial, participants are randomly assigned to either the intervention group or the control group. The intervention group receives the treatment or intervention being studied, while the control group does not.

Non-Randomized Controlled Trials[edit | edit source]

In a Non-Randomized Controlled Trial, the assignment of participants to the intervention or control group is not random. This type of study is often used when it is not ethical or practical to randomly assign participants to groups.

Advantages and Disadvantages[edit | edit source]

Intervention studies have several advantages and disadvantages. They can provide strong evidence about cause and effect relationships, but they can also be expensive and time-consuming to conduct. In addition, ethical considerations can limit the types of interventions that can be studied.
