Abstract:Objective To develop the Evaluation Scale of Workplace Deviance Behavior of Nurses, and to test its reliability and validity. Methods Based on literature review and semi-structured interview, the item tools were identified according to the workplace deviance behavior classification system, and the original scale was formed after a 2-rounds expert consultation with 9 experts. Then a total of 300 nurses attending national training were selected and investigated by convenient sampling method. Results The final scale included 5 dimensions consisting of 21 items. Five common factors were extracted from exploratory factor analysis, which could explain 61.816% of the total variance. Correlation coefficient between each dimension score and the total scale score was 0.650-0.871(P<0.01 for all), and correlation coefficient between subscale scores was 0.340-0.609(P<0.01 for all). The content validity index of the scale (S-CVI) was 0.975, its Cronbach′s α coefficient was 0.937, its split-half reliability was 0.897, and its test-retest reliability was 0.846. Conclusions The Evaluation Scale of Workplace Deviance Behavior of Nurses shows adequate reliability and validity, it is culturally appropriate for nurses self-evaluation on workplace deviance behavior.
