The test-retest reliability of the CAT-MHTM is higher (r=0.92) than traditional fixed-length tests such as the PHQ-9, despite the fact that it asks different items upon repeat testing.

Because the CAT-MHTM adapts to the changing severity of the underlying illness, the same questions are not asked upon repeat testing. This permits high frequency mental health measurement without response bias produced by repeated administration of the same set of items.
