RESUMO
OBJECTIVE: Few studies have examined the impact of cultural processes prevalent in minority ethnic groups such as cancer fatalism and medical mistrust on health-related quality of life (HRQoL) following a cancer diagnosis. The present study examined relationships among ethnicity, HRQoL, and two possible cultural vulnerability factors-fatalistic attitudes and medical mistrust-among an ethnically diverse sample of men with prostate cancer (PC) prior to undergoing active treatment. METHODS: A total of 268 men with localized PC (30% African American, 29% Hispanic, and 41% non-Hispanic White) were assessed cross-sectionally prior to active treatment. Path analyses examined relationships among ethnicity, vulnerability factors, and HRQoL. RESULTS: Ethnicity was not related to HRQoL after controlling for relevant covariates. Hispanic men reported greater cancer fatalism compared with non-Hispanic White men (ß = 0.15, p = 0.03), and both Hispanics (ß = 0.19, p < 0.01) and African Americans (ß = 0.20, p < 0.01) reported greater medical mistrust than non-Hispanic Whites. Fatalism demonstrated a trend toward negatively impacting physical well-being (ß = -0.12, p = 0.06), but was not significantly related to emotional well-being (ß = -0.10, p = 0.11). Greater medical mistrust was associated with poorer physical (ß = -0.14, p = 0.03) and emotional well-being (ß = -0.13, p = 0.04). CONCLUSIONS: Results indicate that fatalistic attitudes and medical system mistrust were more prevalent among minority men. Less trust in the medical system was associated with poorer physical and emotional well-being. Attention to perceptions of the healthcare system and its relation to HRQoL may have implications for targeting culturally driven attitudes that may compromise adjustment to a PC diagnosis.Copyright © 2015 John Wiley & Sons, Ltd.
