前列腺癌筛查率在主要种族群体中有所不同。然而，不同种族人群的筛查行为的可能差异以及心理特征的可能作用仍未得到充分研究。我们检查了来自7个种族群体的44名男性样本（N = 308；在美国出生的欧洲裔美国人，在美国出生的非洲裔美国人，来自说英语的加勒比海地区的男性，海地人，多米尼加人，波多黎各人和东欧人）在前列腺癌筛查方面的差异，以及特质恐惧，情绪调节特征和筛查之间的联系。正如预期的那样，即使在人口因素和可及性得到控制的情况下，两组患者在直肠指检（DRE）和前列腺特异性抗原（PSA）检测的频率上也存在差异。海地男性报告的DRE和PSA检测低于在美国出生的欧洲裔美国人或多米尼加裔美国人，东欧移民男性报告的检测低于在美国出生的欧洲裔美国人；与先前的研究一致，在美国出生的非洲裔美国人与在美国出生的欧洲裔美国人在DRE方面存在差异，但PSA频率没有差异。其次，即使在人口统计、准入和种族控制的情况下，增加特质恐惧也显著改善了模型拟合，包括二次型、倒U型、特质恐惧术语。特质恐惧与种族没有相互作用，这表明它的影响可能在不同群体中同样有效，并且在模型中添加信息处理和情绪调节模式并没有提高模型的拟合性。总的来说，我们的数据表明，恐惧是男性筛查行为的关键心理决定因素之一，在设计增加男性筛查频率的模型中可以有效地考虑到这一点。
Rates of prostate cancer screening are known to vary among the major ethnic groups. However, likely variations in screening behavior among ethnic subpopulations and the likely role of psychological characteristics remain understudied. We examined differences in prostate cancer screening among samples of 44 men from each of seven ethnic groups (N = 308; U.S.-born European Americans, U.S.-born African Americans, men from the English-speaking Caribbean, Haitians, Dominicans, Puerto Ricans, and Eastern Europeans) and the associations among trait fear, emotion regulatory characteristics, and screening. As expected, there were differences in the frequency of both digital rectal exam (DRE) and prostate-specific antigen (PSA) tests among the groups, even when demographic factors and access were controlled. Haitian men reported fewer DRE and PSA tests than either U.S.-born European American or Dominican men, and immigrant Eastern European men reported fewer tests than U.S.-born European Americans; consistent with prior research, U.S.-born African Americans differed from U.S.-born European Americans for DRE but not PSA frequency. Second, the addition of trait fear significantly improved model fit, as did the inclusion of a quadratic, inverted U, trait fear term, even where demographics, access, and ethnicity were controlled. Trait fear did not interact with ethnicity, suggesting its effect may operate equally across groups, and adding patterns of information processing and emotion regulation to the model did not improve model fit. Overall, our data suggest that fear is among the key psychological determinants of male screening behavior and would be usefully considered in models designed to increase male screening frequency.
