This article examines the contribution of concept mapping methodology to the first phase of a study to identify the model(s) implicitly used by staff members of a youth protection agency in crisis situations. Mapping is based on multivariate statistical analyses in which statements produced during a brainstorming session are grouped in weighted clusters. The results are a visual representation of the practitioners' conception of intervention in the context of a crisis. The resulting map shows four particular dimensions of the phnon under study integrated in a conceptual framework to analyze content from individual interviews with other staff members.
