The aims of this experimental study were to evaluate the effectiveness of the Breast self-examination enhancing program on knowledge, health belief, self-efficacy perception and breast self-examination behavior (BSE) of female students in one private university. Health Belief Model was used as a conceptual framework. Two hundred and seventy eight (278) female were selected, using purposive sampling, to participate in activities (interventions) including lecturing,demonstration of breast self-examination using self and breast model, and return demonstration. Data were collected before interventions and again one year after the interventions. The data collection instruments include knowledge assessment forms to measure knowledge of breast cancer and breast self-examination, self-report questionnaire on health belief, self-efficacy,and breast self-examination practice behaviors. Internal consistency of the instruments were tested using Chronbach’s alpha technique (0.88 for knowledge, 0.72 for health belief, 0.92
for self-efficacy, and 0.97 for BSE practice behaviors). Data were analysed using descriptive statistics, Chi Square, and Wilcoxson signed-rank test. The study revealed that after one year of the interventions the assessment scores were increased at p < 0.05 significant level in all four aspects. For instance, 1. knowledge of breast cancer and BSE i.e., severity of cancer in each
stage, 2. health belief i.e., risk of cancer, benefits of BSE, 3. Self-efficacy of BSE, and 4. accuracy of BSE practice. The researcher suggests that such program should be consistently offered and studied the difference factors between the participants who practice BSE and those who are not.
