目的：较低的主观社会经济地位（SSS）始终显示出与健康状况较差的关联，其中与全球自测健康的关系最强。虽然通常被解释为反映了低SSS对健康的影响，但这种关联也可能是由于SSS与负面影响的混淆。在这项研究中，我们试图确定是否负面影响混淆，或者替代地，是在因果路径上将SSS与自评健康联系起来。方法：从美国各地招募的300名成年参与者被随机分为悲伤、羞愧或中性情绪诱导，他们在诱导中写下并想象一个特别能唤起情感的事件。参与者随后完成了SSS，自测健康，抑郁和消极情绪的测量。结果如下：与预测一致，无论是SSS评分还是SSS与自测健康，抑郁和慢性负面影响的相关性都不会因情绪诱导条件而不同，控制与SSS协变的人口统计学因素（e.例如，在一个实施例中，年龄、性别、教育、收入）。此外，慢性负性情感部分解释了SSS和自测健康之间的关系，独立于操纵情绪。结论：这些发现支持了测量SSS的实用性，并提供了证据表明慢性负面影响可能是SSS与全球健康关联的中介因素，而不是混杂因素。
Objective: Lower subjective socioeconomic status (SSS) consistently shows associations with poorer health with the strongest relationships emerging with global self-rated health. Though often interpreted as reflecting the impact of low SSS on health, the association could also arise from confounding SSS with negative affect. In this research we sought to determine if negative affect confounds, or alternatively, is on the causal pathway linking SSS to self-rated health. Method: Three-hundred adult participants-recruited from throughout the United States-were randomized to experience sadness, shame, or a neutral mood induction in which they wrote about and visualized a particularly emotionally evocative event. Participants subsequently completed measures of SSS, self-rated health, depression, and negative mood. Results: Consistent with predictions, neither SSS scores nor the association of SSS with self-rated health, depression, and chronic negative affect differed by mood induction condition, controlling for demographic factors that covary with SSS (e. g., age, gender, education, income). Moreover, chronic negative affect partially explained the relationship between SSS and self-rated health, independent of manipulated mood. Conclusions: These findings support the utility of the measurement of SSS, and provide evidence suggesting that chronic negative affect is a likely mediator of the SSS association with global health rather than a confounder.
