title: Assessing psychological flexibility in patients with chronic pain: the Korean adaptation of the Brief Pain Response Inventory.
abstract: This study investigated the psychometric properties of the Korean version of the Brief Pain Response Inventory (K-BPRI) regarding patients with chronic pain.
  
  
  
  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.
  
  
  
  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.
  
  
  
  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.
