Brief Summary

The aim is to investigate potential barriers to informed decision making in a breast cancer screening context. This is a necessary step prior to developing and investigating improved information or decision aids in a Danish breast cancer screening context.

Conditions

Breast Cancer Female; Mammography Screening; Decision Making; Information Seeking Behavior

Outcome Measures

Primary Outcomes (1)

• Prevalence of women who have made the decision about screening participation prior to screening invitation.

  The main hypothesis for this study is that 80% of Danish women have already made their decision about screening participation when presented to the opportunity framing and 70% when presented to the choice framing. Further, a question about being more or less willing to participate after reading screening information will also provide information for this hypothesis.

  The outcome is assessed when women answer the questionnaire sent out in late June 2022. It will take 5-10 minutes to answer the questionnaire. The questionnaire will be closed after 1.5-2 months.

Secondary Outcomes (3)

• Prevalence of women not taking the presented screening information into account when making their decision about participation.

  The outcome is assessed when women answer the questionnaire sent out in late June 2022. It will take 5-10 minutes to answer the questionnaire. The questionnaire will be closed after 1.5-2 months.

• Prevalence of women not thinking of the screening participation as an actual (individual) choice but something to comply with when invited.

  The outcome is assessed when women answer the questionnaire sent out in late June 2022. It will take 5-10 minutes to answer the questionnaire. The questionnaire will be closed after 1.5-2 months.

• Prevalence of women not wanting to make an informed decision about their own health (and be responsible for their own health).

  The outcome is assessed when women answer the questionnaire sent out in late June 2022. It will take 5-10 minutes to answer the questionnaire. The questionnaire will be closed after 1.5-2 months.

Study Arms (3)

Stage of decision making

OTHER

Same questionnaire for all three arms except validated question "Stage of decision making" followed by question about participation in screening or not when invited at age 50. This is not an intervention but a survey study with three different versions of the questionnaire.

Other: Stage of Decision Making

Choice framing

OTHER

Same questionnaire for all three arms except text and question presenting breast cancer screening as a choice (between screening and alternative of no screening) followed by question about participation in screening or not when invited at age 50. This is not an intervention but a survey study with three different versions of the questionnaire.

Other: Choice framing

Opportunity framing

OTHER

Same questionnaire for all three arms except text and question presenting breast cancer screening as an opportunity (no presentation of alternative) followed by question about participation in screening or not when invited at age 50. This is not an intervention but a survey study with three different versions of the questionnaire.

Other: Opportunity Framing

Interventions

Stage of Decision Making OTHER

Investigating preferences and attitudes towards breast cancer screening information, invitation, and decision making as well as barriers for breast cancer decision making. This will be done by using different framing of information (choice framing vs. opportunity framing), question about stage of decision making, and general questions about screening information and invitation.
