Hypothesis
The study examines how age at baseline affects the trajectory of depressive symptoms in middle and older adulthood over 13 years.
Conclusion
Younger participants had more initial depressive symptoms but flatter trajectories, while older participants started with fewer symptoms but experienced a steeper increase over time.
Supporting Evidence
- Previous research suggested a U-shaped pattern in depressive symptoms across the lifespan.
- The trajectory of depressive symptoms was best captured by a cubic model.
- Participants who were younger at the start had more symptoms initially.
- Older participants had a steeper increase in symptoms over time.
Takeaway
As people get older, their feelings of sadness can change a lot, sometimes getting worse after certain events, like the Great Recession.
Methodology
Hierarchical linear modeling was used to analyze changes in depressive symptoms over 13 years.
Participant Demographics
Community-dwelling adults in New Jersey aged 50-74, with a mean age of 60.53 and 64.3% female.
