As suggests by the Minorities' Diminished Returns (MDR) theory, education attainment and other socioeconomic status (SES) indicators have a smaller impact on the health and well-being of non-White than White Americans. To test whether MDR also applies to happiness, in the present study, Blacks and Whites were compared in terms of the effect of education attainment on the level of happiness among American adults.
General Social Survey (1972-2016) is a series of national surveys that are performed in the United States. The current analysis included 54,785 adults (46,724 Whites and 8,061 Blacks). The years of schooling (i.e., education attainment) and happiness were the main independent variable and the main dependent variable of interest, respectively. In addition, other parameters such as gender, age, employment status, marital status, and the year of the survey were the covariates and race was the focal effect modifier. Finally, the logistic regression model was used to analyze the data.
Based on the results, high education attainment was associated with higher odds of happiness in the pooled sample. Further, a significant interaction was found between race and education attainment on the odds of happiness, showing a larger gain for Whites compared to Blacks. Race-specific models also confirmed this finding (i.e., a larger magnitude of the effect of education for Whites compared to Blacks).
Overall, the MDR theory also applies to the effect of education attainment on happiness. Blacks' disadvantage in comparison to the Whites in gaining happiness from their education may be due to the structural, institutional, and interpersonal racism and discrimination in the US. Therefore, there is a need for economic and public policies that can minimize the Blacks' diminished returns of education attainment and other SES resources.
正如少数族裔回报递减(MDR)理论所表明的那样,受教育程度和其他社会经济地位(SES)指标对非裔美国人健康和幸福的影响比对白人的影响更小。为了检验MDR理论是否也适用于幸福感,在本研究中,对美国成年人中受教育程度对幸福水平的影响在黑人和白人之间进行了比较。
综合社会调查(1972 - 2016年)是在美国进行的一系列全国性调查。当前分析纳入了54785名成年人(46724名白人及8061名黑人)。受教育年限(即受教育程度)和幸福感分别是主要的自变量和感兴趣的主要因变量。此外,其他参数如性别、年龄、就业状况、婚姻状况和调查年份是协变量,种族是关键的效应修饰因素。最后,使用逻辑回归模型对数据进行分析。
基于结果,在汇总样本中,高受教育程度与更高的幸福几率相关。此外,在幸福几率方面,发现种族和受教育程度之间存在显著交互作用,表明与黑人相比,白人的收益更大。特定种族模型也证实了这一发现(即与黑人相比,教育对白人的影响程度更大)。
总体而言,MDR理论也适用于受教育程度对幸福感的影响。与白人相比,黑人在从教育中获得幸福方面处于劣势,这可能归因于美国存在的结构性、制度性和人际间的种族主义及歧视。因此,需要制定经济和公共政策,以尽量减少黑人在受教育程度和其他SES资源方面回报递减的情况。
