INTERVENTION RESEARCH
II. Overview
When you are having a problem with something or someone, you tend to think of a way
or solution to solve the problem. Like for example, you find it difficult to look for a certain
ingredient for your menu, then what would you do? Of course, you are going to find an
alternative for that ingredient. The same goes for research, you think of a way on how to solve
existing problems that you have observed by making an intervention.
III. Discussion
INTERVENTION
In research, intervention is a combination of programs or strategies designed to yield
behavioral changes among individuals or even an entire population. An intervention may
contain educational related programs, new policies, development programs for the
environment, or a health promotion campaign.
INTERVENTION RESEARCH
According to Salkind (2010), intervention research studies the effects of an intervention
on an outcome of interest. The primary purpose of intervention research is to produce a
desirable outcome for individuals in need (e.g., reduce depressive symptoms or strengthen
reading skills). Intervention research is a kind of research where the researcher aims to make
changes in the subject involved in the study. Interventional studies are often performed in
laboratories for clinical trials to establish the beneficial effects of drugs or procedures. But then
again if the researchers wish to determine if a certain program, policy, or strategy is effective,
then intervention research is very useful.
The specific research design used in intervention research is the experimental research.
Whenever you are trying to create something new, in a sense, you are experimenting. For
example, you are trying to find out whether there is a difference in taste between a cup of coffee
with natural white sugar and a cup of coffee with artificial sweeteners. You are intervening
with the typical preparation of a cup of coffee by replacing sugar with artificial sweeteners
(Bacli n.d.).
In an intervention study, participants with the same characteristics are randomly
divided into two groups. One group, called the intervention or experimental group (Group A),
will be given the intervention, which may be a strategical plan or program. The other group,
called the control group (Group B), will not receive the intervention. The two groups are equally
important to the research study because the data obtained from both groups are compared
over time by the researchers. With this setup, intervention research aims to provide a
controlled environment to measure the success of a strategical plan, policy, or other
intervention programs.
4. Blinded Method
• This method is done to ensure the validity of the test. It is also used to avoid biases
from both experimenters and participants.
• Single Blind Method is a procedure in which either the participants or the
experimenters are blind to the manipulation being made.
• Double-Blind Method is a procedure in which both participants and experimenters are
blind in the manipulation being made.

1. Build a picture of the problem. Define and describe the problem to be investigated and the
context in which it is set. Along with this, you can readily have a picture of your target
participants in your study.
2. Formulate an intervention to address the problem. This intervention might be a collected
idea you gathered from previous studies and theories.
3. Invite the target participants of the study by sending them a formal letter. If they wish to
participate in the study, they must give their written consent.
4. You may ask your participants to answer a questionnaire that will serve as your baseline
in identifying the current situation of your participants. This is recommended to ensure
that the intervention group and the control group are having the same characteristics as
possible.
5. Randomly create a comparing group in order to have a comparison of data (intervention
group and control group).
6. During the implementation of the intervention, it is a must to keep a close observation of
both groups.
7. Do not lose any data that you have gathered from both groups.
8. As much as possible, avoid biases in interpreting the data you have gathered from your
participants.
