Subject norms will be measured utilizing the Theory of Planned Behavior Questionnaire. Subjective norms will be measured directly by asking participants to indicate their level of agreement with the following three statements 1) Most people who are important to me think I should get a mammogram in the next two years; 2) Most people who are important to me expect me to get a mammogram in the next two years; and 3) Most people who are important to me would approve of me getting a mammogram in the next two years The minimum value is 3 and the maximum value is 15. A high score indicates a more positive attitude towards mammography.

Perceived behavioral control will be measured directly by asking participants to indicate their level of agreement with the following three statements: 1) Whether or not I get a mammogram in the next two years is entirely up to me; 2) I believe it is feasible to get a mammogram in the next two years; and 3) I am confident that if I wanted I would be able to get a mammogram in the next two years. The scores will be added together to measure how much control do Saudi females have to perform mammography in the next two years. The expected minimum value is 3, while the maximum value is 15. A high score implies higher behavioral control toward mammography.

Involvement is measured utilizing the results from the personal involvement inventory scale (PII) scale. Issue involvement will be answered on a 7-point Likert scale ranging from 1 (Not at all) to 7 (Very much) with six items: important, relevant, interesting, means a lot to me, valuable, and involving. The expected minimum value is 6, while the maximum value of 42 with high scores implies a high level of involvement with the mammography.

Attitude is measured directly by asking participants to indicate their level of agreement with the following three statements 1) Getting a mammogram in the next two years would be good; 2) Getting a mammogram in the next two years would be useful; and 3) Getting a mammogram in the next two years would be safe. The scores will be added together to measure Saudi females' attitudes toward mammography. The expected minimum value is 3, while the maximum value is 15. A high score means a more positive attitude toward mammography
