Evaluation of self-efficacy
A common format for evaluating perceived self-efficacy was used (Theodorakis et al., 2000; Theodorakis,1996).
Participants were informed on their scores in performance on the service test and then indicated
their performance of self-efficacy by responding to question such as “In this specific test of service, I can achieve a score of…..” they indicated the magnitude of self-efficacy by replying to the question.
“How certain you are?” on a 10-point scale anchored by absolutely certain (10) and uncertain (1).
Subjects rated their self-efficacy estimations for performance levels ranging from 10 to 40. Cronbach’s alpha was 0.76, 0.79, and 0.81 for the three measurements, respectively.
