Contextualizing the Effect of Community Social Capital on Racial Health Disparities: The Moderating Role of Racial Segregation and Citizen Ideology
研究种族隔离和公民意识形态如何调节社区社会资本对白人和黑人老年人流感疫苗接种率的影响，发现社会资本的好处不平等地偏向白人，种族隔离削弱了其对黑人的积极作用并加剧了健康差距。
ABSTRACT While public administration research has made important strides in understanding social capital, less is known about how its effects vary across populations and contexts. This study investigates how racial segregation and citizen ideology shape the relationship between community social capital and flu vaccination rates among White and Black Medicare beneficiaries. Findings reveal that although social capital is associated with higher vaccination rates, its benefits are unequally realized, favoring Whites over Blacks. Racial segregation weakens the positive effect of social capital for Blacks and exacerbates health disparities. Liberal ideology amplifies the influence of social capital on vaccination rates for Whites, but this amplifying role is not statistically significant for Blacks or the racial gap. The results highlight the need for scholars to incorporate social equity more explicitly into social capital research, to measure group‐specific social capital, and to account for the structural and cultural contexts that condition its effects.
