On the development of German-language psychological tests and measures in the 2nd half of the 20th century

The electronic data base segment PSYNDEX Tests is produced by the Institute for Psychology Information (ZPID) at the University of Trier. With currently over 5,000 documents, PSYNDEX Tests constitutes the largest test collection in the German-speaking countries. Each data base document is classified according to different criteria, content-wise and formally. Test descriptions offer various possibilities for bibliometric analysis. Here, specific classification categories and the publication year are chosen, regarding psychological and educational tests that were published in a publishing house completely or in parts. Looking at the decades since 1945, the development of German-speaking psychology is reflected in test publishing data, with a boom in psychological-educational tests in the 1970s, the rapid spreading of clinical-psychological diagnostic measures since the same time period, the stagnation of projective procedures since the 1980s, and the rising quality problems in psychological assessment in work, organizational, and personnel psychology.
