The overarching aim of this thesis is to illustrate the usefulness of item response theory (IRT) for practical purposes at the individual person level. Psychological measurement instruments are used to make important decisions (e.g., school admission or personnel selection). In such cases, high-quality measurement instruments are required. IRT can be of help to construct and to evaluate the psychometric quality of psychological tests and can also help researchers to improve measurement at the individual person level. Although IRT originally has been used to determine the quality of cognitive tests (e.g., aptitude testing), in recent years, the se of IRT has become more popular in the non-cognitive domain (e.g., personality).
