Conducting school-based focus groups: lessons learned from the CATS project.

Participation of children in focus groups has received scant attention despite the effectiveness of group interviews in eliciting children's views. Focus groups are a valuable approach for generating qualitative data from children; however, conducting school-based focus groups involves challenges specific to the school milieu and the ages and development of the participants. Lessons learned from conducting school-based focus groups during the Child-Adolescent Teasing Scale (CATS) project are applied to examination of key issues including entry to schools, informed consent and confidentiality, students' cognitive development, safety within the group, and appropriate procedures.
