The experimental group received various interventions such as group education based on the health belief model, individual counseling, and brochures on screening. The training was given by two study team members in the faculty's conference hall, in the form of a presentation, discussion, and question-answer sessions, with the experimental group divided into two groups, lasting approximately 90 minutes. It was completed in 3 sessions with breaks every 30 minutes. For training hours, free hours when students did not have classes were chosen. For each training group, a member of the study team first gave a presentation on breast cancer and breast screening behaviors and BSE (30 minutes). Then, a film was shown on the BSE practice recommended by the World Health Organization (20 minutes) and training was given on how to perform correct and effective BSE on the breast model (20 minutes).

The intervention group within the control group received health education on early diagnosis and prevention of breast cancer once the program was finished for them and all data had been gathered for both groups.

The training included topics such as breast anatomy; breast cancer incidence in Somalia, mortality, morbidity rates; breast cancer risk factors, importance of screening methods; The messages on breast self-examination, health belief models, breast cancer awareness, confidence for BSE, and perceived barriers/benefits for BSE were presented in a PowerPoint presentation. The procedure for performing breast self-examination was described using the English edition of Bristol-Myers Squibb Oncology. In the movie, BSE was made simpler with schematics showing the breast area that needed to be covered. Simple directions on which fingers to use and how to move them over the breast were provided. After the film, the emphasis shifted to helping students gain more self-assurance in their ability to accurately complete each BSE step. Students were encouraged to use proper palpation technique to find lumps by performing a breast examination on a silicone breast model.

After the training, a post-test was administered to the experimental and control groups. Data were collected with "Sociodemographic Questionnaire", "Champion's health Belief Model Scale". Sociodemographic Questionnaire: This survey includes questions such as the age of the students, the education level of the mother and father, family income level, and family history of breast cancer. There were also 7 questions about students' breast cancer and breast self-examination. Champion's health Belief Model Scale: The 42-item Champion Health Belief Model Scale (CHBMS) was refined in subsequent research (1993, 1997, 1999) and was created by Victoria Champion in 1984 to assess women's attitudes and beliefs regarding breast cancer and breast self-examination. CHBMS has 6 subscales.
