Psychological and physical functioning difficulties associated with complex activity limitations among U.S. adults.

Area of Science:

• Public Health
• Health Services Research
• Psychology

Background:

• Limited research exists on psychological functioning as a predictor of complex activity limitations.
• Understanding the interplay between mental and physical health is crucial for assessing functional limitations.

Purpose of the Study:

• To assess the impact of psychological and/or physical functioning difficulties on complex activity limitations in U.S. adults.
• To analyze the combined effects of mental and physical health on daily living, social, and work limitations.

Main Methods:

• Utilized data from the 2006-2010 National Health Interview Survey (n=124,337).
• Developed a six-category variable combining physical and psychological functioning levels (low, moderate, serious distress; with or without physical difficulties).
• Examined limitations in daily living, social participation, and work.

Main Results:

• A significant gradient of increasing risk for complex activity limitations was observed with escalating psychological distress and physical difficulties.
• Individuals with both moderate psychological distress and physical difficulties, and those with serious psychological distress and physical difficulties, faced the highest risk.
• Even psychological distress alone, or physical functioning difficulty alone, increased the risk compared to no/low psychological distress and no physical difficulties.

Conclusions:

• Increasing psychological functioning difficulties exacerbate the risk of complex activity limitations, particularly when coexisting with physical functioning difficulties.
• Mental health significantly contributes to functional limitations, underscoring its importance in overall health and well-being assessments.
• Interventions addressing both mental and physical health are vital for improving individuals' ability to perform major life activities.
