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.
已知前列腺癌筛查率在主要种族群体中存在差异。然而,不同种族亚群体之间筛查行为可能存在的差异以及心理特征可能发挥的作用仍未得到充分研究。我们调查了来自七个种族群体(N = 308;美国出生的欧洲裔美国人、美国出生的非裔美国人、来自英语加勒比地区的男性、海地人、多米尼加人、波多黎各人以及东欧人)、每组44名男性样本的前列腺癌筛查差异,以及特质恐惧、情绪调节特征与筛查之间的关联。正如预期的那样,即使在控制了人口统计学因素和可及性之后,各群体之间的直肠指检(DRE)和前列腺特异性抗原(PSA)检测频率仍存在差异。海地男性报告的DRE和PSA检测次数少于美国出生的欧洲裔美国人或多米尼加男性,而移民东欧男性报告的检测次数少于美国出生的欧洲裔美国人;与先前的研究一致,美国出生的非裔美国人在DRE检测频率上与美国出生的欧洲裔美国人不同,但在PSA检测频率上没有差异。其次,加入特质恐惧显著改善了模型拟合度,加入二次、倒U型特质恐惧项也有同样效果,即使在控制了人口统计学、可及性和种族因素的情况下也是如此。特质恐惧与种族之间没有相互作用,这表明其影响可能在各群体中同等发挥作用,并且在模型中加入信息处理和情绪调节模式并没有改善模型拟合度。总体而言,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,在旨在提高男性筛查频率的模型中应予以充分考虑。
