Qualitative research provides opportunities to study bullying and peer harassment as social processes, interactions and meaning-making in the everyday context of particular settings. It offers the possibility of developing a deep understanding of the culture and group processes of bullying and the participants' perspectives on peer harassment as well. It gives participants opportunities to discuss their own understanding and experiences of bullying in their own words. This article reviews qualitative studies on bullying or peer harassment in school (including some studies in which qualitative and quantitative methods--so-called mixed methods--have been used).
