The development of a psychological test is a carefully planned process that takes place in several phases. Each phase is crucial to ensuring that the finished instrument is reliable and valid. In this article, we take a close look at the test construction phases.

Psychological diagnostics is a fascinating and multifaceted field that has evolved considerably over the past few centuries. From its beginnings in psychiatry to the development of modern classification systems such as the DSM and the ICD, the field has come a long way. In this blog post, I will give you a comprehensive overview of the history of psychological diagnostics and show how diagnostic methods have changed and improved over time.

In psychological assessment, the diagnostic process is at the core of making well-founded decisions and initiating appropriate measures. Whether in clinical psychology, the workplace, or educational counseling, a systematic approach to collecting and evaluating information is essential. In this blog post, I will guide you through the various steps of the diagnostic process and use practical examples to explain how they work.

Item Response Theory (IRT) is a modern method for developing and analyzing psychometric tests, and is widely used particularly in psychology and the social sciences. In contrast to classical test theory (CTT), which makes assumptions about test scores and measurement errors, IRT focuses on the relationship between test responses and the underlying traits of the person being tested.

Classical Test Theory (CTT) is a fundamental model for assessing the accuracy and validity of tests, but it has its limitations. In this article, we take a detailed look at some advanced concepts in CTT, as well as criticisms that have led to new approaches in test theory.
