Difficulty with daily activities, not general physical function, independently predicted psychological distress in chronic obstructive pulmonary disease (COPD) patients. Poor physical function increased activity difficulties, indirectly impacting mental health.

Area of Science:

  • Pulmonary Medicine
  • Psychology
  • Rehabilitation

Background:

  • Chronic obstructive pulmonary disease (COPD) significantly impacts patients' quality of life.
  • Understanding the relationship between functional status and psychological well-being in COPD is crucial for effective management.

Purpose of the Study:

  • To investigate the association between general functional status and specific activity difficulties with psychological distress in individuals with COPD.

Main Methods:

  • Telephone interviews were conducted with 334 individuals diagnosed with COPD.
  • Functioning was assessed using measures of self-care and recreational activity difficulties, and the SF-12 Physical Component Score (PCS).

Main Results:

  • Approximately 16.2% of participants exhibited psychological distress (SF-12 Mental Component Score < 35).

  • Difficulty with self-care (OR=2.1) and recreational activities (OR=7.7) were significant predictors of distress.
  • While general physical function (PCS) did not directly predict distress, it was a risk factor for activity difficulties.

    • Conclusions:

    • Activity-specific difficulties are independent predictors of psychological distress in COPD patients.
    • Poor general physical function indirectly contributes to psychological distress through increased activity limitations.
