The score is a maximum of 36. The mean was 12 and a SD (standard deviation) of 5.
So scores over 17 might flag higher sensitivity, 11-12 suggests moderate sensitivity.
The original questionnaire was a 12 item questionnaire, this is the 6 item version. The score is calculated using each scenario's Nervousness (1-6) x Expectation (1-6) question, then the toal is divided by 6.
