Relative to other ethnic groups in the United States Blacks have disproportionately higher rates of hypertension. Research suggest that perceived racism might moderate the relation between such Pearson variables as John Henryism and cardiac/vascular functioning.
This study examined the possible moderating influence of perceived racism on the John Henryism reactivity relation in a sample of 117 Black female college students (M age = 26.10 years, SD = 8.83).
Blood pressure was measured before and during a speaking task. John Henryism and perceived racism were assessed via self-report.
Hierarchial regression analyses revealed that John Henryism was inversely related to systolic blood pressure reactivity (p = .007). These analyses also indicated that John Henryism and perceived racism interacted to predict both systolic (p = .007) and diastolic blood pressure reactivity (p = .0005). Follow-up regression analyses indicated that John Henryism was unrelated to systolic and diastolic blood pressure reactivity for women high in perceived racism (ps > .62) and was inversely associated with systolic and diastolic blood pressure reactivity for women low in perceived racism (ps < .01).
The findings highlight the importance of examining the potential moderating effects of ethnically relevant situation factors when exploring the relation of John Henryism to blood pressure reactivity.
在美国,相对于其他种族群体,黑人患高血压的比例格外高。研究表明,感知到的种族主义可能会调节诸如约翰·亨利主义等皮尔逊变量与心脏/血管功能之间的关系。
本研究在117名黑人女大学生样本(年龄均值 = 26.10岁,标准差 = 8.83)中,考察了感知到的种族主义对约翰·亨利主义反应性关系可能产生的调节作用。
在一项演讲任务之前和期间测量血压。通过自我报告评估约翰·亨利主义和感知到的种族主义。
层次回归分析显示,约翰·亨利主义与收缩压反应性呈负相关(p = .007)。这些分析还表明,约翰·亨利主义和感知到的种族主义相互作用,可预测收缩压(p = .007)和舒张压反应性(p = .0005)。后续回归分析表明,对于感知到的种族主义程度高的女性,约翰·亨利主义与收缩压和舒张压反应性无关(p值 > .62),而对于感知到的种族主义程度低的女性,约翰·亨利主义与收缩压和舒张压反应性呈负相关(p值 < .01)。
研究结果凸显了在探讨约翰·亨利主义与血压反应性的关系时,考察种族相关情境因素潜在调节作用的重要性。
