2.2.2 Coronavirus Anxiety Scale (CAS)
The CAS, which was developed by Lee9, is a valid and
reliable tool and measures physiological reactions of COVID-19-related
anxiety. The validity and reliability studies of the scale in the
Turkish population were conducted by Akkuzu et al.10.
Each item is scored based on the symptoms experienced within the past
two weeks using a 5-point anchored scale, ranging from 0 (not at all) to
4 (nearly every day). The cut-off score of ≥9 indicate COVID-19-related
anxiety.
