Abstract

|
This study aims to examine the difference in the trajectories of depressive symptoms between older adults (60 years old and older) and younger adults (18 to 59 years old), taking into account psychosocial factors as mediators to explain the potential difference. A form of CES-D is used to measure depressive symptoms. This study employs latent growth-curve modeling to examine the trajectories of depression using panel data (1995-2001) based on a national telephone probability sample of 2,592 adults in the United States. The results indicated that, over time, older adults have worse change in depression than younger adults. Changes in economic hardship, daily work fulfillment, and perceived control play important roles in explaining the difference between older and younger adults. Older adults experience a greater increase in depression than younger adults due to the fact that their relative changes in economic hardship, fulfilling work quality, and perceived control are more negative than those of younger adults. These results highlight the importance of studying depression changes among older adults and the roles of psychosocial factors in such changes.
