Computer Anxiety Rating Scale.
The computer anxiety rating scale is a 19 item questionnaire.
Items are scored on a 1-5 scale, with the total scale score calculated as a sum of the items. Some items have a reversed score, for example 1 becomes 5.
Scores range from 19 (a low level of computer anxiety) to 99 (a high level of computer anxiety).
