To investigate the validity and reliability of the Thai version of the confusion assessment method (CAM).
One hundred five inpatients who were consulted with the psychiatric consultation-liaison service unit, were enrolled in the present study. The validity assessment of the Thai version of the CAM was done by comparing it with the gold standard diagnosis of delirium by psychiatrists using DSM-IV-TR criteria. The reliability assessment was obtained from a sample of 35 patients assessed by two psychiatric residents.
The Thai version of CAM had a sensitivity of 90% and specificity of 94.54. The positive predictive value was 93.75% and the negative predictive value was 91.23%. Likelihood ratio showed 16.5-fold risk of delirium positive through using the Thai CAM Interrater reliability in diagnosis of delirium was high (k = 0.77).
The present study demonstrated that the Thai version of CAM is a valid and reliable tool for assessing and diagnosing delirium in Thailand.
探讨泰国版谵妄评估方法（CAM）的有效性和可靠性。
本研究纳入了105名向精神科会诊联络服务单元咨询的住院患者。通过将泰国版CAM与精神科医生使用DSM-IV-TR标准对谵妄进行的金标准诊断进行比较，来评估其有效性。可靠性评估来自35名由两名精神科住院医师评估的患者样本。
泰国版CAM的敏感性为90%，特异性为94.54%。阳性预测值为93.75%，阴性预测值为91.23%。似然比显示，使用泰国版CAM时谵妄阳性风险增加16.5倍。谵妄诊断的评分者间信度较高（k = 0.77）。
本研究表明，泰国版CAM是泰国评估和诊断谵妄的有效且可靠的工具。
