Summary
This summary is machine-generated.

Individuals with Chronic Obstructive Pulmonary Disease (COPD) often lack confidence, leading to reduced daily activities. A new scale, the COPD Self-Efficacy Scale (CSES), helps identify specific situations that lower self-efficacy in COPD patients.

Area of Science:

  • Pulmonary Medicine
  • Psychology
  • Health Sciences

Background:

  • Chronic Obstructive Pulmonary Disease (COPD) frequently leads to diminished self-efficacy.
  • Low self-efficacy in COPD patients often results in avoidance of daily activities and reduced quality of life.
  • Identifying specific triggers for low self-efficacy is crucial for targeted therapeutic interventions.

Purpose of the Study:

  • To develop and validate a scale to measure self-efficacy in individuals with COPD.
  • To assess the reliability and internal consistency of the new scale.
  • To explore the factor structure of self-efficacy in the context of COPD.

Main Methods:

  • Development of a 34-item COPD Self-Efficacy Scale (CSES).
  • Assessment of test-retest reliability (r = .77).

  • Evaluation of internal consistency using Cronbach's alpha (.95).
  • Exploration of a five-factor structure: negative affect, emotional arousal, physical exertion, environmental factors, and behavioral risks.

    • Main Results:

    • The CSES demonstrated good test-retest reliability.
    • The scale exhibited excellent internal consistency.
    • A five-factor structure was identified, providing insights into specific self-efficacy challenges in COPD.

    Conclusions:

    • The COPD Self-Efficacy Scale (CSES) is a reliable and valid instrument for assessing self-efficacy in COPD patients.
    • The identified factors provide a framework for developing tailored interventions to improve self-efficacy and activity levels in individuals with COPD.
