The domain-of-life approach to subjective well-being (SWB) has been popular for decades. Recognizing the possibility that individuals may not perceive all life domains equally important, many researchers advocate for importance weighting, which is to incorporate the relative importance of life domains (i.e., domain importance) into the scoring of SWB at the individual level. However, the need for and the adequacy of importance weighting remain topics of debate. What has been missing in the debate is the consideration of influences of potential confounding factors. Given that age is significantly associated with domain satisfaction, domain importance, and SWB, assessing importance weighting should not ignore the potential confounding effect of age. Analyzing data from an online survey, we found that adjusting for the confounding effect of age produced negligible changes in the results of assessing the role that domain importance played in the relationship between domain satisfaction and SWB. Our findings support the observations from the literature that the results of assessing importance weighting depended on the SWB variable selected. However, given our non-probability study sample, future studies should continue to consider age as a confounder in assessing importance weighting in the domain-of-life approach to SWB.

生命域主观幸福感（SWB）方法已经流行了数十年。许多研究人员认识到个人可能无法感知所有生命领域同样重要的可能性，因此主张重要性加权，即将生命领域的相对重要性（即领域重要性）纳入个人层面的SWB评分中。但是，重要性加权的必要性和充分性仍然是争论的话题。辩论中缺少的是考虑潜在的混杂因素的影响。鉴于年龄与域满意度，域重要性和SWB显着相关，因此评估重要性权重不应忽略年龄的潜在混杂影响。分析来自在线调查的数据，我们发现，针对年龄的混杂影响进行调整后，评估域重要性在域满意度和SWB之间的关系中所起的作用的结果几乎可以忽略不计。我们的发现支持文献中的观察结果，即评估重要性权重的结果取决于所选的SWB变量。但是，鉴于我们的非概率研究样本，未来的研究应继续将年龄作为评估SWB生命域方法中重要权重的混杂因素。
