Abstract

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.
