Design outcomes

Primary

Measure	Time frame
Knowledge about the breast self-examination technique. This variable will be measured by the response to 13 questions based on the technique recommended by the Clinical Practice Guide of the Mexican Social Security Institute for the prevention, screening and timely referral of suspected cases of breast cancer at the first level of care. It evaluates three areas: observation (4 items), palpation (7 items) and periodicity (2 items). It uses a Likert-type response scale where the option always gives 3 points, almost always 2 points, rarely 1 point and never 0 points. It obtains a maximum score of 39 and a minimum of 0. A high level of knowledge corresponds to a score equal to or greater than 26, a medium score of 13 to 25 points and a low score less than or equal to 12 points. This variable will be measured at baseline and 2 months after the end of the intervention in the impact measurement.	—
