Although puppets have been employed by various disciplines in clinical and community (e.g. homes and schools) environments, little has been written about their use as a communication tool in research. In this article, a critical review of the literature is undertaken integrating the use of puppets in a qualitative research study exploring children's perspectives on and responses to a camp for children with cancer. Methodological considerations and ethical issues of using puppets as a data collection technique are discussed. Although some limitations exist, using puppets in interviews with children appear to help them to identify, clarify and verbalize their feelings.
