This systematic review aimed to explore the contributions of Brazilian nursing literature about the use of interviews as a data collection technique in research with children. Articles were searched in the Virtual Health Library, using Health Terminology, between 1998 and 2008. Thirteen articles were selected, whose analysis allowed for reflections on the type of study, investigated age range, ethical considerations, data collection techniques, among others. Data indicated that nurses have used interviews isolated or associated with other techniques. Studies need to present the data collection phase in further detail, so as to indicate ways to improve the interview technique with children in nursing research.
