Things to Know When Using a Personality Test

Personality tests and inventories are highly effective tools for understanding individuals' behavioral characteristics, sources of motivation and communication styles. When administered correctly, these tests can foster individual development and contribute to teams working more cohesively and efficiently. However, there are some critical issues to consider when administering these tests. Misinterpreted findings or incorrect applications can lead to unexpected negative consequences.

In this article, we will explore how to use personality tests correctly and effectively, what to look out for and best practices. Get expert tips and advice to make the most of the possibilities offered by personality inventories.

Is the area of use appropriate for the purpose? Is it clear in which year the test was developed, by whom, and is it used in academic studies? Are the questions at a level that people from all walks of life can understand? How long should the application period be? Are norms defined in the occupational group to be applied? Is the test suitable for individual or group application? Does it measure what it is intended to measure under all conditions? (Is it reliable?) Does it measure what it is intended to measure? (Is it valid?) If it is a foreign test, has it been standardized? Does it discriminate according to gender, race, socio-economic status, age? Is it sensitive to strengths and weaknesses? Is it discriminatory? Are measures taken to ensure that the candidate does not overestimate or mislead? Is reporting adequate? How many types of reports are prepared?

Is the area of use fit for purpose?

The measurement of the test should be useful for employee selection, career planning and individual evaluation in the business environment. Tests should be created on groups suitable for the target audience.

Is it clear in which year the test was developed, by whom, is it used in academic studies?

A good test should be academically accepted, studied and worked on for a long time, supported by scientific theories and developed by experts in the field.

Are the questions at a level that people from all walks of life can understand?

The content should consist of culturally appropriate concepts that people at all levels can understand. Incomprehensible questions can lead to wrong answers.

How long should the application period be?

The longer the administration time, the longer the candidate may lose interest and motivation. In the case of applications consisting of different tests, a break should be taken and the candidate should be informed of the duration in advance.

Are norms defined in the occupational group to be implemented?

While a general evaluation can be obtained as a result of the tests, what is important is that the characteristics of the person match the characteristics of the job. For this reason, there must be predetermined “comparative values” related to the job group for which the candidate is applying.

Is the test suitable for individual or group administration?

“Group administrations” of the test should be possible when there is a high volume of job applicants.

Does it measure what it wants to measure under all conditions (Is it reliable?)

If the test results are very different between two administrations, there are other factors affecting the test, and the test is not considered reliable. The reliability coefficient of a test ranges from 0-1 and is expected to exceed 0.7 to be considered reliable.

Does it measure what is intended to be measured? (Is it valid?)

If the test is not reliable, it is not valid. However, a reliable test is not necessarily valid. The test should cover every aspect of the criterion it is intended to measure. It should be able to predict job performance and have a high correlation with similar tests. It must support the theories on which it is based.

If it is a foreign test, has it been standardized?

Standardization is a laborious task. Not only does the translation need to be done with statistical analysis, but also the norms need to be established with large groups and made culturally appropriate.

Does it discriminate based on gender, race, socio-economic status, age?

Tests should not discriminate. Eliminating certain questions on the basis of culture, age or gender violates the principle of equality.

Is it sensitive to strengths and weaknesses? Is it distinctive?

Test results should distinguish between low and high scorers on the factors to be measured, and should not be clustered at one extreme.

Have measures been taken to ensure that the candidate does not misrepresent or mislead?

The test should have a mechanism and questions to detect this. Too high face validity creates problems.

Is reporting adequate? How many types of reports are prepared?

Results should be reported in understandable language according to occupational groups and required competencies. Graphic presentations are more helpful in understanding the relationships.

How should it be implemented?

The fact that it is administered by trained psychologists in a standardized environment and interpreted by people with professional expertise makes the test more reliable.

What should the test execution environment look like?

It is necessary to minimize problems that may arise from the implementation. For this reason, care should be taken to ensure that the test environment is the same for each candidate. A bright, quiet, distraction-free environment that is not too hot/cold and provides the candidate with the necessary materials and opportunities to meet his/her needs is suitable for the application.

Should the candidate be notified of the results?

The knowledge of the results by the participants is questionable for various reasons. However, the candidate should still be given basic information about himself/herself.

At which stage of the selection process should it be implemented?

Screening tests are tests that eliminate candidates in terms of the necessary criteria at the first stage. Tests that reveal other personality traits such as managerialism, creativity and occupational groups are applied at more advanced stages of selection.

In tests, can the candidate understand what is being measured and can it be misleading?

This kind of risk is also possible mainly when being interviewed or in the CV. The person who wants to present himself/herself as better than he/she really is may have such a need in real life. In some professions, presenting oneself well is a desirable trait.

Personality tests and inventories are effective tools that help individuals gain a deeper understanding of themselves and their environment.
