The main purpose of this study is to adapt the Bystander Intervention Scale in Bullying and to investigate its validity and reliability for middle school students. The scale was applied to 364 students (191 girls, 173 boys) middle school students for validity and reliability analysis. The construct validity of the scale was tested by CFA, and the goodness of fit coefficients obtained from the analysis were found to be acceptable. The internal consistency coefficient for the whole scale was .88, and for the sub-dimensions of the scale, it was.60 for noticing the event, .78 for interpreting the event as an emergency, .67 for accepting responsibility for help, .75 for deciding how to intervene, and.78 for implementing the decision to intervene. The test-retest reliability coefficient obtained at the four-week interval was.80. It has been concluded that the scale is at a level that can be used in the researches to be conducted on bystander intervention of middle school students in bullying.
