Clinical Report: Patterns of Depressive Symptoms Among Older Adults
Overview
This study identifies reproducible patterns of depressive symptoms in older adults using data from two national cohorts. The findings indicate that specific symptom patterns, particularly the Somatic-Motivational pattern, were associated with higher odds of future elevated depressive symptom status and risks of activities of daily living (ADL) worsening and mortality.
Background
Depressive symptoms in older adults are a significant public health issue, often leading to functional disability, cognitive decline, and increased mortality. Understanding the heterogeneity of depressive symptoms is crucial for effective assessment.

Key Findings
A 4-class solution for depressive symptom patterns was identified: Minimal Symptoms, Somatic-Motivational, Affective-Social, and Global Distress.
The Somatic-Motivational pattern was associated with higher odds of future elevated depressive symptom status in both cohorts.
Participants with the Somatic-Motivational pattern had a higher risk of activities of daily living (ADL) worsening and mortality.
Adding symptom patterns to total score models improved the predictive fit for outcomes.
Cross-cohort structural correspondence was observed with high item-probability correlations for active symptom patterns.
Clinical Implications
The identification of distinct depressive symptom patterns can inform clinical assessments in older adults.
Conclusion
The study demonstrates that depressive symptom patterns can be reliably identified across different cohorts, with specific patterns providing insights beyond traditional total symptom scores.
