What is the Item Response Theory (IRT) and which models are there? - Chapter 14
What is IRT?
The Item Response Theory (IRT) is an alternative to the classical test theory (CTT). The IRT identifies and analyzes the measurements in behavioral sciences. The reaction of the individual to a certain test item is influenced by characteristics of the individual ( trait level ) and properties of the item (difficulty level).
- For a difficult item/question someone needs a high ' trait level' to be able to give a correct answer.
- Conversely, with an easy item / question, someone with a low ' trait level' is enough to give a good answer.

What is the generalizability theory? - Chapter 13
The Generalizability Theory (G theory) helps us to distinguish the effects of multiple facets and then to use different measurement strategies. It is an ideal framework for complex measurement strategies in which several facets influence the measurement quality. This is a fundamental difference compared to the classical test theory (CTT), where different facets are not assumed.
What is a facet and what role do facets play in the complexity of a measurement strategy?
According to the G

What is a confirmatory factor analysis? - Chapter 12
In chapters 4 and 8 we discussed the internal structure (i.e., dimensionality) of a psychological test. As we briefly introduced there, the internal structure of a test has to do with the number and nature of the psychological constructs that we measure with the items. One way to identify those constructs is through factor analysis. In this chapter, we will discuss factor analysis, and in particular confirmatory factor analysis (CFA).
What are EFA and CFA used for?

What types of test bias are there? - Chapter 11
In the previous chapter we discussed response bias, a common threat to the psychometric quality of tests. In this chapter we discuss the second major threat: test bias. Test bias arises when the true scores and the observed scores differ between two groups. Think of men and women as two groups. The emphasis of test bias is therefore on systematic differences between groups of respondents. Please note that the identification of differences between groups does not necessarily mean that there is also (test) bias; it may be that these differences are actually present in reality that way.

What types of response bias are there? - Chapter 10
Chapters 10 and 11 deal with threats to psychometric quality. Two types of threats are central here: reaction bias and test bias. Chapter 10 is about response bias. Test bias is discussed in chapter 11.
What is response bias?
Consciously or unconsciously, cooperative or not, zelfverbet honoring or rather self-effacing, response bias plays a constant role in psychological measurement. Reaction bias means that respondents' reactions (negatively) influence the quality of the psychological measurement. Bias means the bias or bias of responses / outcomes, which are often incorrect.

How to evaluate evidence for convergent and divergent validity? - Chapter 9
In the previous chapter we discussed the conceptual framework of validity, where we could identify five types of proof of validity. One of the types of evidence was convergent and divergent validity: the extent to which test scores have the "right" pattern of associations with other variables. This is discussed further in this chapter.
What is a nomological network?
Psychological constructs are laid down in a theoretical context. The basis of the construct has connections with the basis of other psychological constructs. The connection between the construct and other related

What is validity? - Chapter 8
What is validity?
For more than 60 years the following basic definition of validity was assumed: Validity is the extent to which a test measures what it is intended to measure. Although this definition has been used very much and still is, the concept of validity is presented a little too simple with this definition. A better definition would be that validity is the extent to which the interpretation of test scores for a specific purpose is supported by evidence and theory.

What is the importance of reliability? - Chapter 7
This chapter explains how reliability and measurement errors affect the results of behavioral research. Awareness of these effects is crucial for behavioral research.
- Which two sources of information can help evaluate an individual test score?
- On which two factors does the correlation of observed scores from two measurements depend?
- In addition to reliability, what else should you pay attention to when looking at the results of a study?
- What should you pay attention to in the construction and improvements of tests?
Which two sources of information can help evaluate an individual test score?
There are two important sources of information that can help us evaluate an individual test score. The first is
