Abstract : Pain management has become a major concern for the major international health organizations in the last decade. Pain management can be said to be all the necessary steps employed by health practitioners to ease patients of their pain and to generally improve their quality of life. The Health Belief Model was developed by social scientists at the U.S Public Health Service in order to understand the failure of people to adopt disease prevention strategies or screening tests for the early detection of disease. This study is aimed at evaluating the Health Belief Model (HBM), thereby assessing its ability to adequately estimate nurses' practices in tending to a patient's pain. A cross-sectional study was conducted. 600 questionnaires were distributed through thirteen public hospitals located in the central region of Jordan. Questionnaire validity was confirmed by three experts in pain management. The reliability of the questionnaire was duly confirmed to be 0.98 by Coefficient alpha. The Findings show a percentage as high as 69% which occurs as a result of patients' barriers and self-efficacy regarding pain management. The HBM provides a useful framework for investigating predictors of pain management practices
