Overgeneral and specific autobiographical memory predict the course of depression: an updated meta-analysis

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Psychopathology

Background:

• Overgeneral memory (OGM) is a cognitive feature linked to clinical depression.
• Previous research indicated a small predictive effect of OGM on depressive symptom trajectories.

Purpose of the Study:

• To update a prior meta-analysis on the predictive relationship between OGM and subsequent depressive symptoms.
• To examine the replication of previous findings with a decade of new research.

Main Methods:

• Systematic literature review adhering to the eligibility criteria of a previous meta-analysis.
• Inclusion of 32 studies, doubling the number from the prior review.
• Meta-analysis to estimate effect sizes and explore moderating variables.

Main Results:

• OGM significantly predicts the course of depressive symptoms, supporting previous findings.
• Predictive effects were larger in clinical samples compared to non-clinical samples.
• Higher age showed a trend towards stronger predictive effects, while longer follow-up showed weaker effects.

Conclusions:

• The findings reinforce OGM as a predictor of depressive symptom development.
• OGM represents a potentially modifiable cognitive target for understanding and treating depression.
• Further research into OGM may offer novel therapeutic avenues for depressive disorders.
