This paper addresses the development and effect of health education interventions on compliance behavior and blood pressure control of hypertensive patients. The focus is on two main tactics: 1) the use of a baseline questionnaire to determine the patients' needs in the area of medical regimen management and the translation of that information into education intervention; 2) the development of a group method as a form of internality training providing a needs assessment and simultaneously responding to the assessment. The results supported the study's hypotheses with respect to blood pressure control. Both the theoretical and practical aspects of internality training as a needs assessment process and a skill training process are discussed.
