abstract: BACKGROUND
  Breast cancer is an international health problem in the world over. Mammography screening behavior has critical role in early detection and decreasing of its mortality. Educational programs play an important role in promoting breast cancer screening behaviors and women health. Health belief models (HBM) is the most common models that have been applied in Mammography screening behaviors. The aim of this study was to determine the effect of breast cancer screening education using HBM on knowledge and health beliefs in 40 years women and older.
  
  
  METHODS
  In this Population-based controlled trial, 290 women of 40 years and older were divided randomly into experimental and control groups. Health beliefs determined using the Persian version of Champion's health belief model scale (CHBMS). Questionnaires were completed before and 4 weeks after intervention. Four educational sessions were conducted each session lasting 90 min by lecturing, group discussion, showing slide and educational film based on HBM constructs. The obtained data were analyzed by SPSS (version 18) and statistical test at the significant level of α = 0.05.
  
  
  RESULTS
  Mean scores of perceived susceptibility, perceived severity, perceived benefits, barriers and self-efficacy of mammography and health motivation in the experimental group had significant differences in comparison with the control group after educational intervention (P ≤ 0.001).
  
  
  CONCLUSIONS
  The results of this study have confirmed the efficiency of educational intervention based on HBM in increasing of knowledge and health beliefs about breast cancer and mammography screening behavior. Hence, implementing appropriate educational programs with focus on benefits of Mammography in early detection of breast cancer and creating positive motivation for health among women, can increase their practice of having mammography screening.
