Psychometric evaluation reveals strong reliability and internal consistency in the CPAQ for chronic pain, indicating its applicability.
Key Points
The Polish version of the CPAQ-8 exhibits good psychometric properties, supporting its use in both clinical and research settings.
Confirmatory factor analyses demonstrated a consistent two-factor correlated structure for the CPAQ-8 across two samples, enhancing its validity.
Internal consistency measures for the CPAQ-8 ranged from 0.63 to 0.82, with moderate test-retest reliability, illustrating its stability over time.
Negative correlations between CPAQ-8 scores and factors such as pain anxiety and depression suggest its potential for assessing psychological impacts of chronic pain.
