Persons in the experimental group will be trained 6 times with an interval of 2 weeks via an online platform (zoom, etc.). No training will be given to the control group, and the post-test data will be collected by re-administering the two groups with the mid-test created via Google forms and containing the scales immediately after the training, and the "Health Belief Model Scale in Breast Cancer Screening" and "Breast Cancer Screening Beliefs Scale" two months later.
