COVID-19 Bilgi, Tutum ve Davranış Ölçeği (CBTDÖ)

The knowledge part of the COVID-19 scale consists of 10 items and two dimensions. The Cronbach alpha value of the COVID-19 knowledge section is 0.86 in total, the contagion knowledge dimension is 0.71 and the prevention knowledge dimension is 0.84. When items are deleted in both sub-dimensions, there is no item that increases the Cronbach’s alpha value. It is seen that the item–total correlation adjusted for overlap in each dimension is not less than 0.4. The test–retest consistency ICC value for the knowledge dimension of the scale was 0.83, 0.71 for the contagion knowledge sub-dimension, and 0.87 for the prevention knowledge sub-dimension. The COVID-19 attitude section consists of four sub-dimensions and 13 items classified within the framework of SIM. Cronbach’s alpha values of perceived susceptibility, severity, benefit and disability sub-dimensions in the attitude section are 0.77, 0.75, 0.73, 0.59 and 0.70, respectively. Cronbach’s alpha value did not increase when the item was deleted for each sub-dimension, and the item–total correlations were above 0.4. The test–retest consistency ICC value for the total attitude scale was 0.93, and it was 0.91, 0.96, 0.88, and 0.87 for the perceived susceptibility, severity, benefit, and disability sub-dimensions, respectively.
