Abstract

Purpose

Chronic pancreatitis (CP) is a chronic fibroinflammatory pancreatic disease that severely impacts patients’ quality of life (QoL). The Pancreatitis Quality of Life Instrument (PANQOLI) is an 18-item measure specifically designed to assess QoL amongst patients with CP. This study aimed to develop a Chinese version of PANQOLI and assess its reliability and validity in the Chinese CP cohort.

Methods

Translation was performed according to forward-backwards translation steps and transcultural adaptation. Five hundred Mandarin Chinese-speaking patients with CP were enrolled, 250 for the exploratory factor analysis (EFA) and 250 for the confirmatory factor analysis (CFA). Item analysis, reliability analysis (internal consistency, split-half reliability, test–retest reliability), and validity analysis (content validity, construct validity, and convergent validity) were performed.

Results

Item analysis of the Chinese version of PANQOLI revealed that the absolute t values of all items were > 3. Reliability analysis showed that Cronbach’s α coefficient was 0.868, split-half coefficient was 0.934, and intraclass correlation coefficient was 0.859, demonstrating excellent reliability. For content validity, item level content validity index (I-CVI) ranged from 0.8 to 1.0, and average of I-CVI scores across all items (S-CVI/Ave) was 0.91. In construct validity analysis, EFA produced four dimensions after rotation, and results of CFA showed χ2/df = 2.346, comparative fit index (CFI) = 0.929, Tucker–Lewis index (TLI) = 0.915, and root-mean-square error of approximation (RMSEA) = 0.074. The analysis of convergent validity indicated that the Chinese version of PANQOLI was moderately correlated with the physical (r = 0.436, P < 0.001) and mental component summary (r = 0.518, P < 0.001) of the 36-Item Short Form Health Survey.

Conclusion

The Chinese version of PANQOLI appears to be culturally appropriate, reliable, and valid for assessing the QoL amongst Chinese patients with CP.
