Does perceived unfairness influence psychological well-being differently according to age? We sought to examine the association between perceived unfairness and psychological distress, testing whether and how age moderates the association. Data were drawn from the Korean General Social Survey, a nationally representative cross-sectional sample, collected in 2 years (2011, 2012). The survey measured two types of perceived unfairness: distributive and procedural unfairness. We found that both types of perceived unfairness were positively and independently associated with psychological distress. Our results also showed effect modification by age; in other words, the harmful effects of perceived distributive and procedural unfairness on psychological distress decreased with age, suggesting that younger people were more distressed by perceived unfairness than older people. Our findings suggest that perceived unfairness is harmful to psychological well-being, but its effects become less salient as people age.

感知的不公平和心理困扰：随着年龄的增长，有害程度降低了吗？

感知的不公平是否会根据年龄对心理健康产生不同的影响？我们试图研究感知的不公平与心理困扰之间的联系，测试年龄是否以及如何缓解这种联系。数据取自于2年（2011年，2012年）收集的全国代表性横截面样本《韩国综合社会调查》。该调查测量了两种类型的感知不公平：分配不公平和程序不公平。我们发现，两种类型的感知不公平都与心理困扰正相关且独立。我们的研究结果还表明，随着年龄的增长，效果会有所改变。换句话说，随着年龄的增长，分配性和程序性不公平对心理困扰的有害影响有所降低，这表明，与老年人相比，年轻人更容易受到不公平感的困扰。我们的发现表明，不公平感不利于心理健康，但随着年龄的增长，其影响变得不那么明显。
