PURPOSE: To develop an Arabic version of Intensive Care Delirium Screening Checklist (ICDSC) and assess its validity and reliability among critically ill patients. MATERIALS AND METHODS: Multicentered study of convenience sample of adult ICU patients. Arabic translation was performed with rigorous back-to-back translation methods. Concurrent validity was established by calculating the sensitivity and specificity of two examiner assessments compared to a psychiatric evaluation. Kappa coefficients describe interrater reliability, whereas Cronbach alpha and composite reliability depict internal consistency. RESULTS: Three hundred critically ill patients were enrolled. Of these, validity testing was assessed in 180 patients. ICDSC screening was positive for delirium in 11% of enrolled patients. The area under the receiver operator characteristic (ROC) curve is 0.9413, with predicted sensitivity 70% (95% confidence interval [CI]: 60-81%) and specificity 99% (95% CI: 98-100%). The Arabic ICDSC showed acceptable internal consistency (Cronbach alpha=0.63 and composite reliability=0.64). Interrater agreement was excellent (Kappa coefficient []=0.85). CONCLUSIONS: Arabic ICDSC is a valid and reliable delirium-screening tool among Arabic-speaking ICU population. Future studies could address whether these findings are generalizable to a higher proportion of mechanically ventilated patients, and address acceptability and reliability in other Arabic language critical care settings.
