The purpose of this study was to examine the stability of satisfaction with eight domains of life as well as satisfaction with life in general. The study used a nationally representative Australian sample collected during 20 years between 2001 and 2020 (N = 33,341). Using the Multi-Trait-Multi-State model, the total variance in each item was partitioned into three components: common consistency (proportion of variance attributable to stable influences), occasion specificity (proportion of variance attributable to situational influences or person-situation interactions), and measurement error (proportion of variance attributable to random and nonsystematic influences). The consistency, specificity, and error estimates for the nine items averaged about 48%, 11%, and 41%, respectively. Satisfaction with health, financial situation, and general life was more stable than variable, whereas the other domains were more variable than stable. The most stable item was satisfaction with health and the least stable was satisfaction with the home in which one lives. On average, domain satisfaction was less stable than general life satisfaction. Satisfaction with housing, safety, and health were the best predictors of general life satisfaction. A supplementary analysis showed that life evaluations were less stable in young adulthood than in older age.

本研究的目的是检验对生活八个领域的满意度以及对一般生活的满意度的稳定性。该研究使用了在 2001 年至 2020 年的 20 年间收集的具有全国代表性的澳大利亚样本（N = 33,341）。使用多特质多状态模型，将每个项目的总方差分为三个部分：共同一致性（归因于稳定影响的方差比例）、场合特异性（归因于情境影响或人情交互的方差比例） ) 和测量误差（随机和非系统影响造成的方差比例）。九个项目的一致性、特异性和错误估计值平均分别约为 48%、11% 和 41%。对健康、财务状况的满意度，一般生活稳定多于变化，而其他领域多变多于稳定。最稳定的项目是对健康的满意度，最不稳定的是对居住家庭的满意度。平均而言，领域满意度不如一般生活满意度稳定。对住房、安全和健康的满意度是一般生活满意度的最佳预测指标。一项补充分析表明，青年期的生活评价不如老年期稳定。和健康是总体生活满意度的最佳预测指标。一项补充分析表明，青年期的生活评价不如老年期稳定。和健康是总体生活满意度的最佳预测指标。一项补充分析表明，青年期的生活评价不如老年期稳定。
