How do you conduct a screening survey?

There are three key points to consider when creating a screening survey.

Make the questions exit cell phone number list sure to extract the subjects of this survey
Ensure sufficient sample size
Be aware of calculation methods to ensure sample size
An important point when designing a screening survey is to avoid asking questions that reveal the content of the actual survey.

When conducting a screening survey, be sure to keep in mind that the contents of the survey should not be made known to the participants.



Make the questions sure to extract the subjects of this survey


When conducting a screening survey, it is important to select only those people who meet the eligibility criteria for the survey.

For example, this survey targets people who are seriously considering managing an apartment complex.

As a screening survey, let's say you ask the question, "Are you interested in managing an apartment complex?"

In this case, people who are only somewhat interested and enthusiastic enough to actually order a pamphlet and listen to the explanation will answer "yes."

If you answer a survey with a "yes" or "no" answer, the answer will be the same regardless of your level of interest.

In cases where screening surveys are created in this way, many people will proceed to the main survey.

It is important to note that even grey areas who do not meet the conditions will be included in this survey.

It is important to clarify the purpose of the study and provide detailed questionnaire questions in the screening survey.



Ensure sufficient sample size


In screening, there is a certain percentage of responses that are received.

However, the proportion of people surveyed in this survey will naturally be lower than the number of people who responded to the screening survey.

Response rates to screening surveys also vary depending on the open rate of the email requesting the survey and the amount of the reward.

If the conditions of this survey were made stricter, the number of people eligible to participate would be reduced, making it difficult to secure a large sample.

It's very important to be clear about your requirements, but it's also important to strike a balance between whether you can secure enough respondents.



Be aware of calculation methods to ensure sample size


When conducting a screening survey, it is necessary to ensure the sample size required for the main survey.

The concepts of response rate and occurrence rate can help you gather your target sample size.



Response rate

The response rate is the percentage of people who responded to a screening survey, main survey, etc., out of the total number of people surveyed.

If we can get 600 people out of 1,000 to respond to the screening survey, that's 60%.

Response rates also vary depending on the amount of compensation offered for completing the screening survey, the number of questions asked, and survey open rate.



Appearance Rate

This refers to the percentage of people who meet the criteria among all people who responded to the screening survey.

If 70 out of 100 people are affected, the incidence rate can be said to be 70%.

The occurrence rate tends to decrease when the target conditions are more detailed or when the target area is narrowed down to a specific dirty area.

When conducting a screening survey, it is important to decide in advance the target sample size you want to ensure when conducting the actual survey.

It is important to conduct the survey while taking into consideration the balance between response rate and occurrence rate.



Screening survey examples


What kind of questions should be included in the screening survey?

Let's take a look at some examples of questionnaire-style questions used in actual screening surveys to get ideas for how to create them.

Here are two examples of screening.

Case 1: "User of an electric bicycle from competing bicycle manufacturer A"
Example 2: "Someone who has purchased Company B's laundry detergent at a drugstore in the past three months"
