The current study examined age-related psychometrics and differences in the measurement, mean-levels, variances, and correlations of gratitude and future time perspective across adulthood using data from a cross-sectional survey in a representative Swiss sample (N = 1684, age range: 19–98 years). Local structural equation modeling was used to investigate these measurement parameters based on age as a continuous variable instead of using artificial age groupings. After having established a measurement model with three interrelated factors of gratitude, opportunities and time, results indicate that the measurement model demonstrates at least metric measurement invariance for all factors. Gratitude mean-levels and correlations with future time perspective remained stable across the examined age range. We did find a strong decline in perceived remaining opportunities and time across age, and an increase in the variance of these constructs. This suggests that people generally perceive time and opportunities as more limited with increasing age, but that the interindividual differences in this perception are particularly large in old age.

目前的研究使用来自具有代表性的瑞士样本的横断面调查的数据，检查了与年龄相关的心理测量学以及成年期感恩和未来时间前景的测量、平均水平、方差和相关性的差异（N = 1684，年龄范围：19-98 岁）。使用局部结构方程模型来研究这些基于年龄作为连续变量的测量参数，而不是使用人工年龄分组。在建立了包含感恩、机会和时间三个相互关联的因素的测量模型后，结果表明该测量模型至少证明了所有因素的度量测量不变性。在所检查的年龄范围内，感恩的平均水平和与未来时间前景的相关性保持稳定。我们确实发现随着年龄的增长，感知到的剩余机会和时间显着下降，并且这些结构的方差增加。这表明人们普遍认为时间和机会随着年龄的增长而变得更加有限，
