Abstract
In 2013, a special issue of the Spanish journal Clínica y Salud published a review on symptom and performance validity assessment in European countries (Merten et al. in Clínica y Salud, 24(3), 129-138, 2013). At that time, developments were judged to be in their infancy in many countries, with major publication activities stemming from only four countries: Spain, The Netherlands, Great Britain, and Germany. As an introduction to a special issue of Psychological Injury and Law, this is an updated report of developments during the last 10 years. In that period of time, research activities have reached a level where it is difficult to follow all developments; some validity measures were newly developed, others were adapted for European languages, and validity assessment has found a much stronger place in real-world evaluation contexts. Next to an update from the four nations mentioned above, reports are now given from Austria, Italy, and Switzerland, too.
