The study sample consists of 542 adults. The sociodemographic information form prepared by the researcher, The Bullying Questionnaire, The Second Revision of the Revised Cyber Bullying Scale - II and The Dirty Dozen Scale were used for data collection. For the analysis of the data, exploratory and confirmatory factor analysis was performed using SPSS 26 and AMOS 24 programs. Kaiser-Meyer-Olkin (KMO= .940) Measure of Sampling Adequacy and Bartlett’s Test of Sphericity (x2= 6150.337, sd=153, p<.05) were conducted to determine the conformance of data to factor analysis. According to the exploratory factor analysis, the final version of the scale accounts for 51% of the total variance and consists of 18 items gathered under 1 factor. Confirmatory factor analysis was used to test the results obtained as a result of exploratory factor analysis. It was concluded that the results obtained from confirmatory factor analysis (CMIN/DF= 5.021, GFI= .90, CFI= .92, NFI= .91, RMSEA= .09, RMR= .048) were consistent with the findings of exploratory factor analysis. Cronbach's alpha, item-total correlation, test-retest and similar scale validity methods were used in the validity and reliability analyses of the scale. The Cronbach's alpha internal consistency coefficient obtained from the overall scale was calculated as .94. The findings obtained as a result of the analyses were discussed in the framework of the literature, and it was determined that the Bullying Questionnaire had the necessary psychometric properties English Adult Bullying, Bully, Bullying, Reliability, Validity https://ktppdergisi.com/wp-content/uploads/2025/03/1-The-Adult-Bullying-Scale-An-Adaptation-Study-1.pdf https://ktppdergisi.com/en/makale/the-adult-bullying-scale-an-adaptation-study/ https://ktppdergisi.com/wp-content/uploads/2025/03/1-The-Adult-Bullying-Scale-An-Adaptation-Study-1.pdf English References 3 12
