Abstract

Purpose
This methodological study aimed to translate the Korean version of the Patient-Reported Outcomes Measurement Information System^® item bank-emotional distress (i.e., depression, anxiety, and anger) for adults and evaluate its psychometric properties.
Methods
Translation involved forward translation, back translation, expert review, harmonization and quality assurance, and cognitive testing. Psychometric properties were evaluated with a community sample of 201 adults. To assess the unidimensionality of the measures, we used factor analysis to examine construct validity.
Results
All items of the Patient-Reported Outcomes Measurement Information System item bank-emotional distress measures were translated through a rigorous translation process, and semantic, conceptual, and normative equivalences between the original and Korean version were ensured. Exploratory factor analysis revealed that all items loaded on one dominant factor. The Korean Patient-Reported Outcomes Measurement Information System measures demonstrated acceptable psychometric properties and unidimensionality.
Conclusion
The Korean version of the Patient-Reported Outcomes Measurement Information System item bank-emotional distress (i.e., depression, anxiety, and anger) for adults is reliable and valid. Hence, it may be utilized extensively in clinical and research settings and contribute to patient-centered care.
