Quality of Life Assessment Among Ethnically Diverse Black Prostate Cancer Survivors: A Constructivist Grounded Theory Approach.

ABSTRACT

Purpose: Prostate cancer (CaP) is the most common cancer in Black men (BM), and the number of Black CaP survivors is rapidly increasing. Although Black immigrants are among the fastest-growing and most heterogeneous ethnic groups in the US, limited data exist regarding their CaP experiences. Therefore, this study aimed to explore and model the experiences of ethnically diverse Black men with CaP. Methods: In-depth interviews were conducted with 34 participants: Native-born BM (NBBM) (n=17), African-born BM (ABBM) (n=11), and Caribbean-born BM (CBBM) (n=6) CaP survivors recruited through QR-code embedded flyers posted in Black businesses, clinics, social media platforms, and existing research networks within the US. Guided by Charmaz's constructivist grounded theory methodology, the interviews were analyzed using constant comparison following key stages of initial, focused, and theoretical coding using Atlas.ti v23. Results: Participants were thirty-four men aged 49-84 years (mean±SD, 66±8). Most were married (77%), likely to be diagnosed at Stage I (35%), and treated with radiotherapy (56%). Our study findings explored the complex trajectory of Black prostate cancer (CaP) survivors, unveiling a comprehensive model termed "Journeying through Unfamiliar Terrain." Comprising three phases and 11 sub-phases, this model uniquely captures the pre-diagnosis awareness and post-treatment adaptation among survivors. Conclusion: The resulting theoretical model delineates the entire CaP survivorship process among BM, providing contextual and conceptual understanding for developing interventions and enhancing patient-centered care for ethnically diverse CaP survivors, pivotal in bridging the gaps in survivorship research and healthcare practices.
