Peer bullying and victimization levels will be assessed using the Peer Bullying Identification Scale - Adolescent Form. The minimum score that can be obtained from the bully and victim subscales of the scale is 53, and the maximum score is 265. As the score obtained from the scale increases, the level of being a bully and a victim also increases.

Empathy and sympathy levels will be measured using the Empathy and Sympathy Scale in Adolescents, which includes cognitive empathy, emotional empathy, and sympathy subscales. The minimum score that can be obtained from the scale is 12, and the maximum score is 60. The scale score is calculated by taking the mean of the item scores. A high score obtained from the scale indicates a high level of empathy or sympathy, whereas a low score indicates a low level of empathy or sympathy.
