Concurrent validity, or evidence that can be gathered to defend the use of a test for predicting other outcomes, was supported as there was significant correlation between the result from the 7 items and the HADS and PVDS results:
- depression:  r = 0.425, p < 0.001
- anxiety:  r = 0.511, p < 0.001
- perceived infectability:  r = 0.483, p < 0.001
- germ aversion:  r = 0.459, p < 0.001
