10.63. Notes

  • CamCOPS does not suffer and has not suffered from the GAD-7 reproduction error noted by Zorowitz et al. (2021), Lancet Psychiatry 8: 180, https://pubmed.ncbi.nlm.nih.gov/33610220/, https://doi.org/10.1016/S2215-0366(21)00001-8. (The error, noted in a large number of publications, was to use “not at all sure” as the “zero” or lowest-value response, which is incorrect, rather than the correct option of “not at all”.)
