However, there is a shortage of validation in clinical samples, and none for the newly developed 11-item version. Thus, this study aimed to test the reliability and validity of the ASRM-11 in comparison with the ASRM-5.Methods Through a retrospective chart review, self-reported data on the Korean ASRM (K-ASRM) were collected from 122 patients diagnosed with either bipolar or depressive disorder via a (semi)structured diagnostic interview. They were interviewed individually using the Korean Young Mania Rating Scale (K-YMRS). The reliability, construct, convergent, and diagnostic validity were also examined.Results The reliability of both versions of the K-ASRM ranged from good to excellent. Factor analyses revealed a unifactorial solution for K-ASRM-5, while a dual-factor structure emerged for K-ASRM-11, corresponding to the bright and dark sides of (hypo)mania. Moreover, both versions demonstrated a significant positive correlation with the total K-YMRS score. In the receiver operating curve analysis, the discriminating ability of both versions was fair when distinguishing manic from non-manic patients.Conclusion Both the K-ASRM-5 and K-ASRM-11 demonstrated comparable levels of sound psychometric properties, which supports their continued usage in research and clinical practice. It is necessary to test potential utility of the K-ASRM-11 for symptom monitoring and treatment response because of its additional coverage of dark-side (hypo)manic symptoms, including irritability and impulsivity, which are considered important for the quality of life of patients with bipolar disorder.<\/jats:p>","DOI":"10.30773\/pi.2025.0241","type":"journal-article","created":{"date-parts":[[2026,3,12]],"date-time":"2026-03-12T07:24:17Z","timestamp":1773300257000},"page":"460-467","update-policy":"https:\/\/doi.org\/10.30773\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Is Longer Always Better?
