| 目的研究意识模糊评估方法中文修订版（CAM-CR）在住院痴呆患者中的适用性。方法使用CAM-CR评定住院老年痴呆患者174例，通过因子分析评估该量表的结构效度，以DSM-IV谵妄诊断标准为金标准，评价问卷的诊断效度。通过评定者一致性检验、内部一致性检验评价量表的信度。结果因子分析剔除2个条目后形成9个条目的2因子模型；诊断谵妄的临界值为24分，灵敏度0.97，特异度0.89，与临床诊断的一致性系数Kappa值0.74。CAM-CR条目和总分的评定者一致性组内相关系数（ICC）在0.80~0.91；CAM总量表的内部一致性Cronbacha系数为0.71，2个因子的a系数为0.75、0.69。结论CAM-CR在老年痴呆患者中有较好的效度和信度，适用于老年痴呆患者叠加谵妄的筛查。 |

| Abstract: |
| Objective To evaluate the applicability of Confusion Assessment Method Chinese Revision (CAM-CR) in hospitalized dementia patients. Methods The delirum status of hospitalized dementia patients was assessed with 11 item CAM-CR. The structural validity of the scale was evaluated by using the factor analysis; the diagnostic validity of the scale was evaluated using the DSM-IV diagnostic criterion for delirium as the gold standard. The reliability of the scale was evaluated by the internal consistency test and consistency test of evaluators. Results The factor analysis eliminated two items, then two factors model CAM scale was formed. With 24 points as the cut-off value for diagnosis of delirium, the sensitivity and specificity were
0.97 and 0.89, respectively; the coefficient Kappa value of clinical diagnosis was 0.74. The consistency ICC for the entries and the total score of the CAM-CR was between 0.80~0.91; the Cronbach-α coefficient of the total CAM was 0.71, the Cronbach-α coefficient of the two factors was 0.75 and 0.69. Conclusion The revised CAM has good reliability and validity, which is suitable
for the screening delirium in dementia patients. |
