Though cross-sectional research has suggested that sense of purpose declines into older adulthood, it remains unclear whether inter-individual variability occurs in these trajectories, and what factors predict these trajectories. The current study provides one of the first longitudinal investigations into how individuals' sense of purpose fluctuates in older adulthood.
Participants from the Health and Retirement Study (n = 4,234, mean age = 65 years), completed assessments of sense of purpose over three years, along with multiple potential predictors (health, personality, demographics) at the start.
Second-order latent growth models demonstrated both mean-level declines on purpose over time, as well as the capacity for inter-individual variability in change patterns for retired adults. Among this cohort, health status, educational attainment, and marital status were significant predictors of purpose trajectories over time, though broad personality trait dimensions failed to uniquely predict change in sense of purpose. However, measurement invariance tests suggest that the scale did not operate similarly across work status groups.
Findings advance the previous literature by demonstrating inter-individual variability in sense of purpose for those participants who had retired. Future research should consider that purpose inventories may operate differently for those in the workplace versus retired adults.
尽管横断面研究表明,目标感在老年期会下降,但目前尚不清楚这些轨迹是否存在个体间的可变性,以及哪些因素可以预测这些轨迹。本研究首次对个体在老年期的目标感波动情况进行了纵向调查。
健康与退休研究(n=4234,平均年龄=65 岁)的参与者在三年内完成了目标感评估,并在开始时完成了多项潜在预测因素(健康、个性、人口统计学)的评估。
二阶潜在增长模型表明,随着时间的推移,目标感的平均值会下降,同时对于退休人员来说,变化模式也存在个体间的可变性。在这一队列中,健康状况、教育程度和婚姻状况是目标轨迹随时间变化的显著预测因素,但广泛的人格特质维度未能独特地预测目标感的变化。然而,测量不变性检验表明,该量表在工作状态组之间的运作方式并不相同。
本研究通过证明那些已经退休的参与者的目标感存在个体间的可变性,从而推进了之前的文献。未来的研究应考虑到,对于在职人员和退休人员,目标清单可能会有不同的运作方式。
