Abstract

The aim of this study was to construct and validate a scale for measuring the dimensions of Bullying in adolescents. The method used in the preliminary construction of the items was based on a library study of theoretical concepts and validation by experts using the content validity ratio coefficient CVR (Lawshe, 1975) and content validity index CVI (Waltz & Bausell, 1981). Structural equation modeling was used to evaluate the validity and factor analysis of the scale by using the Partial Least Squares Method. In the content validity phase, 40 items were prepared and 35 items were approved by experts. In the initial study with a sample size of 48 people, 3 items were removed and 32 items remained, which formed the initial scale. The study population was Iranian adolescents that Their age was 12 to 19. Sampling was done by available method and the sample size was 639 people. Examination of the data in exploratory factor analysis showed that 29 items had acceptable factor load and the other 3 items that did not have acceptable factor load were removed. Examination of the data showed that the 3-factor structure has the best fit in the structural model and explains 53.99% of the variance in total. Confirmatory factor analysis and validation of the remaining items showed that the scale of measuring bullying in adolescents is a reliable self-report scale for use in research related to measuring the prevalence and tendency to bullying and superiority seeking.
