TAPAS - Tailored Adaptive Personality Assessment System Computerized Adaptive Testing (CAT) Questions and Answers

Question 1

Which of the following is a primary advantage of using Computerized Adaptive Testing (CAT) in the TAPAS assessment compared to a traditional fixed-form personality test?

Accepted Answer

It significantly reduces the number of questions needed while maintaining measurement precision.

Answer

CAT tailors the assessment to the individual by selecting questions based on their previous answers. This allows TAPAS to gather sufficient information for an accurate assessment with roughly 50% fewer items than a traditional test, making the process more efficient.

Question 2

A military recruit is taking the TAPAS assessment. After responding to several items, the CAT algorithm presents a question designed to differentiate between two closely related personality facets. This is an example of the system attempting to:

Accepted Answer

Maximize the informational value of the next item based on the recruit's estimated trait levels.

Answer

The core of a CAT system like that used in TAPAS is its ability to dynamically select the most informative item for a specific individual at their current estimated trait level. By choosing an item that provides maximum information, the test can achieve precision more quickly.

Question 3

The psychometric model that forms the foundation for the item selection process in the TAPAS CAT is known as:

Accepted Answer

Item Response Theory (IRT)

Answer

Item Response Theory (IRT) is the mathematical framework that allows CAT to work. IRT models the relationship between a person's underlying trait level and their probability of endorsing a specific item. TAPAS uses IRT to select the most appropriate items for each test-taker.

Question 4

One of the key design features of TAPAS, which is enhanced by its CAT administration, is its attempt to be resistant to 'faking good'. How does the CAT format contribute to this goal?

Accepted Answer

By presenting items with two statements balanced for social desirability in a forced-choice format.

Answer

TAPAS uses a multidimensional pairwise preference (MDPP) or forced-choice format, where applicants must choose between two statements that are roughly equal in social desirability. This design, administered adaptively, makes it more difficult for an individual to consistently present a false but positive profile compared to simple Likert-scale questions.

Question 5

In the context of TAPAS, what is the role of the 'item bank' in the Computerized Adaptive Testing process?

Accepted Answer

A large, pre-calibrated pool of questions from which the algorithm selects items.

Answer

A CAT system relies on a large and diverse item bank. Each item in the bank is pre-calibrated with statistical properties (based on IRT) that describe its difficulty and discrimination. The adaptive algorithm draws from this bank to select the most appropriate question for each person at each stage of the test.
