Purpose
This study investigated the psychometric properties of the Korean version of the Brief Pain Response Inventory (K-BPRI) regarding patients with chronic pain.
Methods
This study employed a retrospective survey design. One hundred sixty-four Korean patients with chronic pain participated in the study. Construct validity was assessed using confirmatory factor analysis and Pearson correlation. Internal consistency reliability, test–retest reliability, and measurement error were examined using Cronbach’s α, the inter-item correlation coefficients, and the item-total correlation coefficients; the intra-class correlation coefficient; and the standard error of measurements, respectively.
Results
Confirmatory factory analysis showed the best fit to the data for the adjusted two-factor structure of the K-BPRI. The K-BPRI demonstrated good internal consistency and test–retest reliability. Measurement errors for the K-BPRI and subscale scores were standard error of measurements = 5.74, 5.63, and 10.26, respectively, and minimum detectable change = 15.86, 15.56, and 28.35, respectively. Weak-to-moderate negative correlations were observed between the K-BPRI and the numerical rating scale for pain intensity and the Hospital Anxiety Depression Scale, and moderately positive correlations were observed between the K-BPRI and Short Form-12.
Conclusion
This study provided evidence for the psychometric properties of the K-BPRI, suggesting that it can be a brief and efficient instrument for measuring psychological flexibility in coping with chronic pain.
