As part of the journal’s new “Practical Guidance” section, whose objectives are outlined, the first article examines the perceptions of health held by professionals, institutions, and users (identification grid). The term is defined, incorporating cognitive, affective, and environmental elements. Two types of classification are proposed: one relating to the construction of a representation, the other to the overall conception of health. These elements should serve to establish a common understanding among all participants in a working group.
