Finally, test-retest, criterion validity and confirmatory factor analysis of the questionnaire were performed with 96 respondents.<h4>Results</h4>An initial questionnaire was devised. The exploratory factor analysis demonstrated four factors: emotional response (six items), self-worth (five items), physical impacts (three items) and social communication (two items). The cumulative contribution of the factors was 65.057%. Cronbach's alpha coefficient of the questionnaire was 0.876. The correlation coefficient between the questionnaire and General Self-Efficacy Scale was 0.565 (p<0.01). A 16-item questionnaire and its factorial structure were confirmed.<h4>Conclusions</h4>The 16-item questionnaire had good reliability and validity.
