The Centrality of Religiosity Scale (CRS) offers a religious psychological perspective on how religious content is represented and anchored in a person's mental system. It addresses questions such as which section of the potentially infinite universe of religious semantics is present in a mental system at all and which position the personal religious system occupies in the overall mental system of an individual (central, subordinate or marginal). In numerous empirical studies, the Z-scale has proven to be a highly reliable and valid instrument.
