BACKGROUND

Chemopreventive agents such as selective estrogen receptor modulators and aromatase inhibitors have proven efficacy in reducing breast cancer risk by 41% to 79% in high-risk women. Women at high risk of developing breast cancer face the complex decision of whether to take selective estrogen receptor modulators or aromatase inhibitors for breast cancer chemoprevention. <i>RealRisks</i> is a patient-centered, web-based decision aid (DA) designed to promote the understanding of breast cancer risk and to engage diverse women in planning a preference-sensitive course of decision making about taking chemoprevention.

OBJECTIVE

This study aims to understand the perceptions of women at high risk of developing breast cancer regarding their experience with using <i>RealRisks</i>—a DA designed to promote the uptake of breast cancer chemoprevention—and to understand their information needs.

METHODS

We completed enrollment to a randomized controlled trial among 300 racially and ethnically diverse women at high risk of breast cancer who were assigned to standard educational materials alone or such materials in combination with <i>RealRisks</i>. We conducted semistructured interviews with a subset of 21 high-risk women enrolled in the intervention arm of the randomized controlled trial who initially accessed the tool (on average, 1 year earlier) to understand how they interacted with the tool. All interviews were audio recorded, transcribed verbatim, and compared with digital audio recordings to ensure the accuracy of the content. We used content analysis to generate themes.

RESULTS

The mean age of the 21 participants was 58.5 (SD 10.1) years. The participants were 5% (1/21) Asian, 24% (5/21) Black or African American, and 71% (15/21) White; 10% (2/21) of participants were Hispanic or Latina. All participants reported using <i>RealRisks</i> after being granted access to the DA. In total, 4 overarching themes emerged from the qualitative analyses: the acceptability of the intervention, specifically endorsed elements of the DA, recommendations for improvements, and information needs. All women found <i>RealRisks</i> to be acceptable and considered it to be helpful (21/21, 100%). Most women (13/21, 62%) reported that <i>RealRisks</i> was easy to navigate, user-friendly, and easily accessible on the web. The majority of women (18/21, 86%) felt that <i>RealRisks</i> improved their knowledge about breast cancer risk and chemoprevention options and that <i>RealRisks</i> informed their (17/21, 81%) decision about whether or not to take chemoprevention. Some women (9/21, 43%) shared recommendations for improvements, as they wanted more tailoring based on user characteristics, felt that the DA was targeting a narrow population of Hispanic or Latina by using graphic novel–style narratives, wanted more understandable terminology, and felt that the tool placed a strong emphasis on chemoprevention drugs.

CONCLUSIONS

This qualitative study demonstrated the acceptability of the <i>RealRisks</i> web-based DA among a diverse group of high-risk women, who provided some recommendations for improvement.
