Promoting Informed Choice for Breast Cancer Screening: A Longitudinal Study
Study Details
Study Description
Brief Summary
Participants will be sent 3 surveys via email and a final brief survey conducted by email or phone. The four surveys will be collected 1) upon enrollment and prior to the primary care appointment; 2) following the primary care appointment; 3) 3 months after enrollment; 4) 1 year after enrollment. The final 2 surveys will offer an increased incentive to increase retention rates.

Detailed Description
Participants will be sent 3 surveys via email and a final brief survey conducted by email or phone. The four surveys will be collected 1) upon enrollment and prior to the primary care appointment; 2) following the primary care appointment; 3) 3 months after enrollment; 4) 1 year after enrollment. The final 2 surveys will offer an increased incentive to increase retention rates. Time 1 will be an online survey (REDS survey) that addresses Aim 1. Time 2 will present a brief summary of mammography evidence as a reminder for the participant. Participants will repeat the REDS survey. Time 2 will additionally assess the following: 1. Whether screening was discussed with the provider. 2. If screening was not discussed, why not (e.g. did not want to, no time, other pressing issues, etc.). 3. If screening was discussed, (a) what was discussed (i.e. benefits, false positives, overdiagnosis), (b) overall satisfaction with the discussion, (c) whether the provider offered a screening recommendation, (d) open-ended qualitative response eliciting how the discussion went. 4. Whether discussed the BCS-DA with anyone else (e.g., friends or family). 5. Patient activation. 6. Preferred role in decision-making. 7. Perceived barriers to screening. Finally, participants' information environment will be assessed using questions from Pearlman et al. (1997), 8. information seeking (e.g. to what extent the participant valued opinions from the provider, friends, and family), 9. information sharing and communication (e.g. screening attitudes of friends and family), and 10. perception of self as disseminator of mammography-related information. Time 3 and Time 4 (at 3 and 1 year, respectively) will repeat the summary of mammography evidence and measures from Time 2. Additionally, the team will assess whether screening was received up to one year after study enrollment using the participant's electronic medical record.

Outcome Measures
Primary Outcome Measures
- REDS (Reactance, self-Exemption, Disbelief and Source derogation) reactions to mammography benefits [12 months]
Reactance, self-Exemption, Disbelief and Source derogation in reaction to evidence about mammography benefits. This is a multi-item measure (3-4 questions per subscale) and assessed on a 1 (strongly disagree) to 5 (strongly agree) Likert scale. Averages will be computed to create for scores (corresponding to each sub scale), with a maximum score of 5 and minimum score of 1.
- REDS (Reactance, self-Exemption, Disbelief and Source derogation) reactions to mammography harms [12 months]
Reactance, self-Exemption, Disbelief and Source derogation in reaction to evidence about mammography harms (over diagnosis and false positive results). This is a multi-item measure (3-4 questions per subscale) and assessed on a 1 (strongly disagree) to 5 (strongly agree) Likert scale. Averages will be computed to create for scores (corresponding to each sub scale), with a maximum score of 5 and minimum score of 1. Reactions to over diagnosis and false positives will be assessed separately.
- Screening intentions question [12 months]
This is a single item question in which participants will indicated their intentions to initiate regular screening with mammograms, using a 4 category response: 1. screen now, 2. wait until they are older but before age 50, 3. wait until age 50, or 4. do not intend to screen in the future at any age
- Number of participants who receive screening in the study period [12 months]
We will use medical records to identify whether the participant has received screening in the 12-month study period
Secondary Outcome Measures
- Change in breast cancer screening knowledge from pre- to post-decision aid [12 months]
Breast cancer screening knowledge is assessed immediately before and after the decision aid, and at follow up survey time points. Screening knowledge is assessed with a 10-item multiple choice questionnaire developed in prior research (Hersch et al., 2015). Minimum score=0/10 (0% correct), maximum score=10/10 (100% correct).
- Whether the participant had a conversation with their doctor about screening [12 months]
Assessed after the clinic appointment, participants report whether they talked with their doctor about screening in that appointment using a 3-category response: 1. No, not at all, 2. Yes briefly, 3. Yes in some detail
- Change in medical mistrust from pre- to post-decision aid [12 months]
Medical mistrust (Eaton et al. 2015) is a 6-item validated scale that is administered before the decision aid, after decision aid, and at follow up surveys. Questions are answered using a 1-5 strongly disagree-strongly agree Likert scale. Minimum score=1, maximum score=5.
- Perceptions of breast cancer risk [12 months]
This is a multi-item validated scale to assess perceptions of personal risk, the TRIRISK measure (Ferrer et al. 2016). Scale items are modified to assess perceived breast cancer risk. In this study we assess only the deliberative and affective subscales. Questions are answered using Likert scales. Minimum score=1, maximum score=5.
- Emotional responses to the decision aid [12 months]
The validated Berlin Emotional Responses to Risk Instrument (BERRI; Petrova et al., 2022) is used to assess emotional response to the decision aid. Participants indicate how they felt when they read the decision aid (angry, worried, hopeful, etc.), responding on a 1-7 Likert scale. Mean scores (min=1, max=7) are computed for positive emotion (assured, hopeful, relieved), anxiety (anxious, afraid, worried) and anger (angry, mad).
- Whether the participant plans to talk to their doctor about screening in an upcoming appointment [12 months]
Assessed after the decision aid but before the clinic appointment. Participants indicate whether they intend to discuss breast cancer screening with their doctor using a 4-category response: 1. Definitely not, Probably not, Probably yes, Definitely yes
