The preliminary K-PICS-KT was then evaluated for validity and reliability. Validity evidence was examined using known-groups validity and item analysis. Reliability was evaluated by assessing internal consistency with the Kuder\u2013Richardson Formula 20 (KR-20) and temporal stability with a test\u2013retest design.Results: Content validity assessment produced a preliminary K-PICS-KT comprising 54 items across four domains. Known-groups validity was supported (p &lt; .001). During item analysis, one item was removed because of a low item\u2013total correlation and content review, resulting in a final K-PICS-KT comprising 53 items across four domains. The KR-20 coefficient was .97, and the test\u2013retest intraclass correlation coefficient was .94. Evidence supporting content validity, known-groups validity, item discrimination, internal consistency reliability, and test\u2013retest reliability was established.Conclusion: The K-PICS-KT developed in this study can be used to measure PICS knowledge among intensive care unit nurses, develop educational programs to improve knowledge, and evaluate the effectiveness of PICS education programs.<\/jats:p>","DOI":"10.7586\/jkbns.26.027","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T01:02:10Z","timestamp":1787792530000},"page":"413-427","update-policy":"https:\/\/doi.org\/10.7586\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cross-cultural
