Summary
Life stressors can worsen depression after treatment by depleting psychosocial resources. This study shows that negative life events erode personal and social resources, leading to increased depressive symptoms long-term.
Area of Science:
- Psychology
- Psychiatry
- Longitudinal Studies
Background:
- Depression relapse is a significant concern following treatment.
- Understanding long-term functioning and relapse predictors is crucial.
Purpose of the Study:
- To examine the long-term impact of life events on posttreatment functioning in depression.
- To test a model where psychosocial resources mediate the relationship between life changes and depression.
Main Methods:
- An integrative structural equation model was used.
- 165 depressed patients were followed for 9 years posttreatment.
- Changes in life events, psychosocial resources, and depressive symptoms were analyzed.
Main Results:
- Negative life events were associated with a decline in psychosocial resources.
- A decline in resources predicted an increase in depressive symptoms.
- Resource change fully mediated the link between life events and depression.
Conclusions:
- Life stressors contribute to persistent depression by diminishing personal and social resources.
- Maintaining psychosocial resources is vital for long-term recovery from depression.
- The findings highlight the importance of addressing life stressors and supporting resource development in depression management.
