A score on the SHAI indicates pathological health anxiety if the total is 20 or more; a score of 10 is normal as all should have some concern over their health. The difference of 9.6 points at 96 months between nurse therapists and others shows both the success and persistence of the therapy. Reproduced with permission from Tyrer P, Wang D, Crawford M et al.
