The content validity index was assessed by a panel of 5 delirium care experts; item discrimination was assessed with data from 120 ICU nurses. A purposive sample of 318 ICU nurses completed the Delirium Knowledge Questionnaire for ICU nurses (DKQ-I) for principal component analysis, reliability, and construct validity of the final instrument.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>The content validity index for the initial 36 items was 0.89, indicating good validity. Item discrimination (range = 3.59-9.55) reduced items to 22; principal component analysis eliminated 5 items. The resulting 17-item DKQ-I had a 4-factor solution, namely, risk factors, signs and symptoms, precipitating factors, and management strategies, which explained 44.08% of the total variance. Cronbach's <jats:italic toggle=\"yes\">\u03b1<\/jats:italic> for internal consistency was 0.72; 2-week test-retest reliability was good (<jats:italic toggle=\"yes\">r<\/jats:italic> = 0.90). Scores on the delirium knowledge questionnaire were significantly associated with level of nursing education.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>The newly developed DKQ-I is a reliable, valid, and rapid test that can assess ICU nurses' level of knowledge, which could be used to provide more immediate improvements in delirium care for patients in the ICU.<\/jats:p>\n
