The intensity of religious affiliation in young persons should be examined. For this purpose a questionnaire with 18 items was distributed to 160 young persons. A modified religious socialisation index by Huber was chosen to measure religious socialisation. With Huber's "centrality scale" it is possible to measure the system of constructs within Abrahamic religions. The regularity and intensity of a religious construct system can provide a valid measure of its centrality within the personality.
