摘要:The aim of this study is two folded: 1) to analyze the reliability and validity of a cyberbullying behaviour questionnaire (CBQ) in working life and 2) to analyze the reliability and validity of a short version of a cyberbullying behaviour questionnaire (CBQ-S) in working life. A total of 3371 working adults (MAge = 49.85 years) in Sweden, and 238 (MAge = 35.61 years) in the USA participated in the study. The results of the Exploratory Structural Equation Modeling (ESEM) showed that the one-factor model had an excellent fit to data, and Cronbach’s alpha indicates that both scales are reliable. In addition, the criterion validity of the scales was demonstrated by significant correlations with the following theoretically relevant concepts: wellbeing, work engagement and intention to quit. The results of the study support the use of the CBQ and CBQ-S as reliable and valid measures of cyberbullying behaviour in working life.
