Violence in schools is an important public health problem affecting the health and safety of schools. Peer bullying, which is a common form of school violence, is defined as the behaviour of a bully person or group that deliberately hurts and upsets a person who is weaker than him/her more than once and causes stress in the person exposed to this situation. In peer bullying, there are roles as victim, bully and audience. Bullying has serious consequences on children in all roles. It affects both health and academic success. There are individual, familial, school-related and environmental reasons for peer bullying. There is a significant increase in the rates of peer bullying both in the world and in our country. It is most common in the middle school period among school periods. Self-compassion, a protective factor for individuals, can be expressed as the understanding they show to themselves in the face of negative situations they have encountered throughout their lives. Individuals with self-compassion can approach themselves with love and compassion when they make mistakes or face difficulties in life, thinking that this situation is unique to human beings. When the common characteristics of bullies and victims are examined, it is seen that they experience depression and anxiety, are angry and cannot communicate effectively. Not criticising oneself if it is destructive and cruel, having a compassionate attitude towards oneself protects the individual from negative feelings and thoughts, improves self-esteem and leads to a decrease in depression and anxiety. It is seen that people with high levels of self-compassion exhibit less aggressive behaviour. In this study, a 7-week self-compassion development programme will be implemented for secondary school students.

Peer bullying is a significant school and public health problem that affects school safety and the health of individuals in the school. Peer bullying is a type of aggression in which one or more students intentionally and continuously harass weaker students, and the victim is unable to protect himself. In order for the disturbing situation to be considered peer bullying, there must be an unequal power relationship between individuals, and this situation must be intentional and continuous (Uz, 2018; Olweus, 1999). When the results of recent research and the news in the media are examined, it is seen that violence and bullying incidents in schools, which affect children's academic success and psychological development, are increasing among children and adolescents. According to the 2022 report of the OECD's Programme for International Student Assessment (PISA), on average 20% of students across OECD countries report that they are bullied at least a few times a month. This rate, which was 19% in our country in PISA 2015 data, is reported as 27% according to 2022 data. According to studies, the incidence of peer bullying increases during secondary school (Gökkaya and Sütçü, 2020; Grant et al., 2019; https://pisa.meb.gov.tr/ , Access date: 22/10/2024).

Compassion is to approach failure or error by thinking that it can be a common experience for all people instead of hurting people. Compassion involves being sensitive to other people's sadness, sharing the pain of other individuals, and understanding the people in front of us without judging them. Self-compassion, a protective factor for individuals, can be expressed as the understanding they show themselves in the face of negative situations they encounter throughout their lives. Individuals who show compassion to themselves do not make harsh judgments and self-criticism towards themselves. Self-compassion can also be defined as an individual trying to understand themselves without prejudice, and behaving kindly and compassionately towards themselves instead of judging or criticizing themselves harshly. Self-compassion has three basic components: self-kindness, perception of common human experience, and awareness (Kurtoğlu and Başgül, 2021). Not criticizing oneself if one is destructive and cruel, and being able to have a compassionate attitude towards oneself protects the individual from negative feelings and thoughts, improves self-esteem, and causes a decrease in depression and anxiety (Germer and Neff, 2019). In a study evaluating psychological well-being in the adolescent population, it was observed that there was a significant negative relationship between stress, anxiety, depression levels and self-compassion levels in adolescents (Marsh et al., 2018). There are other studies supporting the fact that individuals with high self-compassion levels exhibit less aggressive attitudes towards other people (Fresnics and Borders, 2017; Sommerfeld and Bitton, 2020). Individuals who cannot show self-compassion have difficulty developing appropriate understanding in the painful experiences of others (Saricaoğlu and Arslan, 2019). When the information obtained from the literature is evaluated, it is thought that the self-compassion development program will have an effect on middle school students' bullying and victimization.

The research was planned as a randomly assigned intervention and control group, pre-test, post-test after the intervention and follow-up test three months after the intervention. The data will be collected with Personal Information Form, Identifying Victims of Peer Bullying Scale, Identifying Peer Bullies Scale and Self-Compassion Scale Short Form.

It was aimed to reach a total of 102 students, 51 in the experimental group and 51 in the control group, out of the students enrolled in the 5th grade (N=185) in the Milli Eğitim Vakfı Middle School in Usküdar district of Istanbul province. The participants were assigned to groups by lot.

This study aims to evaluate the effects of a self-compassion development program on bullying and victimization among secondary school students.
