Which Are the Most Burdensome Functioning Areas in Depression? A Cross-National Study

Area of Science:

• Global health research
• Psychiatry
• Gerontology

Background:

• Investigated the most burdensome functioning domains in depression.
• Examined the impact of these domains on quality of life (QoL).
• Included participants from diverse global regions: Asia, Africa, Europe, and Latin America.

Purpose of the Study:

• To identify the most burdensome functioning domains in depression.
• To determine the differential impact of these domains on quality of life (QoL).
• To analyze these effects across nine countries in Asia, Africa, Europe, and Latin America.

Main Methods:

• Analyzed data from the World Health Organization's Study on Global Ageing and Adult Health (SAGE) and Collaborative Research on Ageing in Europe (COURAGE).
• Assessed eight functioning domains and QoL in 4051 individuals with depression.
• Utilized pooled and cross-national analyses, stratified by gender.

Main Results:

• Affect, domestic life/work, and interpersonal activities were the most affected functioning domains.
• Women experienced similar patterns to the total sample; men showed non-significant results for mobility, self-care, cognition, and pain.
• Affect and interpersonal activities were consistently problematic across countries, while other domains varied.

Conclusions:

• Significant variation exists in functional decrements across countries in individuals with depression.
• Reporting aggregate functioning scores can obscure individual differences.
• Functioning assessment tools must capture individual distinctiveness for tailored interventions.
