e24122 Background: Using multiple channels and theory-based recruitment messaging are strategies to enroll diverse audiences in cancer clinical trials (CCTs) and reducing sociodemographic health disparities. 1-7 Customizing recruitment content to participants, such as including race-concordant images (i.e., images that match participants race/ethnicity) and translating information to a community-level (i.e., message framing) is linked to positive health-seeking behavior among minorities and their intention to enroll in clinical trials. 8,9 Drawing on Communication Accommodation Theory and social identity theories, this paper evaluated recruitment channels used to successfully enroll underrepresented participants in CCTs, and preferences for race-concordant images and message framing. Methods: Social media ads, flyers, and postcards were used to recruit rural, African American/Black, and Hispanic adults interested in cancer prevention and screening. Participants ( N = 430, M = 40 years old, SD = 14.47, range 18-85) were recruited to the study with unique links to track the stimuli they viewed, and demographics were collected. Participants viewed one of four images and one of two motivational recruitment message frames. Specifically, given our interest in recruiting rural, African American/Black, and Hispanic populations to CCTs, three images were selected to feature each population, and a fourth Inclusive image featuring all three. Additionally, the person-centered message frame conveyed participating in research is motivated by one’s own benefit, whereas the other-centered frame conveyed motivation for other people’s benefit. Results: In social media ads, across a three-week campaign there were 2,653 clicks on recruitment stimuli ads, resulting in a 6.17% response rate of recruited and enrolled. Across all recruitment channels, enrolled participants engaged with the Inclusive (n = 202) and Black/African American (n = 130) recruitment stimuli the most. In the case of framing, person- (n = 174) and other-centered (n = 199) had similar engagement. Investigating within-race preferences, a chi-square analyses revealed Black/African American participants preference for Inclusive (n = 172) and Black/African American (n = 109) visuals over Hispanic (n = 13) and Rural (n = 17), X 2 (30, N = 419) = 194.94, p < .001; as well as preference for other-centered (n = 180) vs person-centered (n = 129) framing, X 2 (30, N = 419) = 183.95, p < .001. Conclusions: Our findings indicate that Black/African American participants are more likely to interact with race-concordant or sociodemographic inclusive stimuli, and a preference for other-oriented framing. To reduce health disparities in CCT participation, recruitment must avoid monolithic approaches and instead segment outreach by sociolinguistic and social identity factors.

Objectives Communication barriers, such as channels, comfort, and location, can negatively impact Black prostate cancer survivors’ experiences and health outcomes after treatment. Addressing these barriers promotes a survivor-centric approach that views survivors as active partners in their care. This study explored the communication preferences of Black prostate cancer survivors, focusing on preferred channels, sources, and locations for enhanced quality of life. Design Using grounded theory methodology, we conducted engaged in-depth interviews with 7 Black prostate cancer survivors, centering on their post-treatment experiences. We analyzed participant transcripts to develop codes and themes. Communication accommodation theory (CAT) was applied to examine how survivors adapt their communication styles to navigate barriers and improve their quality of life. CAT helped identify key patterns of survivors’ convergence and divergence in their communication with healthcare providers, crucial for developing survivor-centric communication strategies. Results The analysis revealed the importance of acknowledging cultural and racial perspectives in post-treatment survivorship. Themes extracted from the transcripts included communication barriers, preferences for information channels, and favored locations for sharing information. Survivors expressed a preference for a balance between face-to-face interaction and telehealth, with environments that provide safety and support playing a key role in encouraging vulnerability and open dialogue. Inclusive healthcare practices were seen as essential in empowering Black survivors to engage in meaningful communication without feeling silenced or undervalued, thus fostering a dignified quality of life. Conclusion Tailoring post-treatment communication practices to incorporate cultural sensitivity, inclusive healthcare, and safe spaces is pivotal to supporting Black survivors. These findings provide a pathway to improving survivors’ experiences and empower them to actively shape their survivorship journey. Moreover, they highlight Black men’s need for trustworthy communication with healthcare providers and peers during the post-treatment period, emphasizing the importance of direct, personalized interactions.
