There is growing concern in the United States about avoidable, unjust differences in health associated with sociodemographic characteristics, such as socioeconomic status and race/ethnicity. This concern has sparked research to identify how disparities develop and how they can be reduced. Studies showing that disparities occur at all levels of socioeconomic status, not simply at the very bottom, suggest that psychosocial factors play an important role. The author discusses both content and process issues in psychological research on disparities.
美国越来越关注与社会人口特征（如社会经济地位和种族/民族）相关的可避免的、不公正的健康差异。这种担忧引发了研究，以确定差距是如何产生的，以及如何减少这些差距。研究表明，差距不仅出现在社会经济地位最低的人群中，而是出现在各个层次，这表明心理社会因素发挥了重要作用。作者讨论了心理差异研究中的内容和过程问题。
