生活满意度与更长的寿命有关，但其随时间的变化还没有被检查相对于寿命。我们调查了随时间变化的生活满意度的平均水平、随时间变化的生活满意度及其相互作用是否与9年随访的死亡率相关。参与者是4，458名最初年龄≥50岁的澳大利亚人。在随访期间，有546人死亡。调整年龄后，更高的平均生活满意度与风险降低相关，生活满意度的更大变异性与死亡风险增加相关。这些研究结果是合格的一个显着的相互作用，这样的个人与低平均满意度和高变异性的满意度有最大的死亡风险在随访期间。结合生活满意度的平均水平，生活满意度的变化与老年人的死亡风险有关。考虑个体内变异性提供了对心理特征与健康之间关联的额外见解。
Life satisfaction is associated with greater longevity, but its variability across time has not been examined relative to longevity. We investigated whether mean levels of life satisfaction across time, variability in life satisfaction across time, and their interaction were associated with mortality over 9 years of follow-up. Participants were 4,458 Australians initially ≥50 years old. During the follow-up, 546 people died. Adjusting for age, greater mean life satisfaction was associated with reduced risk and greater variability in life satisfaction was associated with increased risk of mortality. These findings were qualified by a significant interaction such that individuals with low mean satisfaction and high variability in satisfaction had the greatest risk of mortality over the follow-up period. In combination with mean levels of life satisfaction, variability in life satisfaction is relevant for mortality risk among older adults. Considering intraindividual variability provides additional insight into associations between psychological characteristics and health.
