[Health education programs: elements of critiquing].

Health education programs don't always meet expectations. This article analyzes the factors that contribute to their failure, including complexity or underutilization of theoretical models, and poor articulation of research. Another factor is the disparity in approaches to understanding and intervening in the health experiences of the public. The author briefly describes three main approaches to health education--the individual, the ecological and the interactional--to suggest new avenues for work, deliberation and assessment. Also discussed is the need to clarify limits, foundations and objectives of health education. Finally, the role of the nurse in practical and research activities is examined. These activities are challenging and demanding and require informed, determined commitment.
