One of the measures we use for reliability in testing is the test/re-test reliability factor. This measures the likelihood of a result being repeated by the same person after a specific interval. The test/re-test reliability of the NBIŽ as researched in July 2004 with an 8 month interval between tests was as follows for each quadrant in The NBIŽ profile:
L1 0.851
L2
.0.840
R1
.0.867
R2 0.918
