Context Breakthrough cancer pain has not been properly evaluated and treated because there are relatively few available measurements. The Breakthrough Pain Assessment Tool (BAT) is currently recognized as a brief, multidimensional, and reliable measurement. Objectives The objective of this study was to validate the Korean version of the BAT (BAT-K) in adult cancer patients. Methods We conducted a forward-backward translation and cross-cultural equivalence test. The psychometric properties with 120 cancer patients were assessed using factor analysis, reliability, and validity. Results The Korean translation was well accepted by participants. Factor analysis revealed the presence of two underlying factors: frequency/severity and duration/medication efficacy. Cronbach alpha coefficient was 0.743. Severity, distress, and disruption of normal life showed strong reliability. The intraclass correlation for the test-retest reliability was 0.782 (95% confidence interval 0.694–0.854). The BAT-K had significant correlations with the Brief Pain Inventory, Pain Management Index, and Eastern Cooperative Oncology Group performance status (all P values < 0.05). Conclusion The BAT-K is a valid and reliable measurement of breakthrough cancer pain in Korean cancer patients.
