Abstract

Mental well-being consists of hedonic/subjective, psychological, and social dimensions. Research has yet to determine how much of the variance in these three dimensions is stable or variable over time. This study used data from South Korea (N = 338) and the Netherlands (N = 2,094) to answer this question. Data were collected over a period of approximately 14 months in Korea (four time points) and 10 months in the Netherlands (four time points). The study used the Mental Health Continuum–Short Form (MHC–SF) to measure dimensions of well-being and the Multi-Trait Multi-State model for data analysis. Results showed a moderate degree of stability for the three dimensions, with the proportion of stable variance ranging from 51% to 61% (M = 58%). Item-level analysis provided more detailed insights into item stability, which helped clarify some of the concept-level results. Despite the large differences between Korea and the Netherlands in cultural values and well-being, estimates of stability and change were quite similar across the two countries. However, some modest cross-cultural differences were also found. The study provides insights that can help researchers and practitioners in the selection or construction of well-being items for various research and practical settings.

心理健康包括享乐/主观、心理和社会维度。研究尚未确定这三个维度的方差有多少是稳定的或随时间变化的。本研究使用韩国 ( N = 338) 和荷兰 ( N = 2,094) 的数据来回答这个问题。韩国的数据收集时间约为 14 个月（四个时间点），荷兰的数据收集时间为 10 个月（四个时间点）。该研究使用心理健康连续体简表（MHC-SF）来衡量幸福感的维度，并使用多特质多状态模型进行数据分析。结果显示，三个维度具有中等程度的稳定性，稳定方差的比例范围为 51% 至 61%（ M = 58%）。项目级分析提供了对项目稳定性的更详细的见解，这有助于澄清一些概念级结果。尽管韩国和荷兰在文化价值观和福祉方面存在巨大差异，但两国对稳定和变化的估计却非常相似。然而，也发现了一些适度的跨文化差异。该研究提供的见解可以帮助研究人员和从业者为各种研究和实践环境选择或构建幸福项目。
