Abstract

Objective

To establish the validity and reliability of the Anosognosia Questionnaire in Dementia (AQ-D) in individuals diagnosed with major neurocognitive disorder (MND) in the Colombian population.

Methods

The AQ-D scale was adapted and validated for MND patients in Colombia through cognitive interviews and expert review. A total of 189 pairs of participants, consisting of caregivers and patients, were included in the study and administered the AQ-D questionnaire. Structural validity, internal consistency, discriminative and concurrent criterion validity, convergent validity, and test–retest feasibility were assessed.

Results

After exploring three models in confirmatory factorial analysis, a four-dimension model was adopted to evaluate the validity of the AQ-D scale. The scale demonstrated good internal consistency (Cronbach's alpha and McDonald's omega above 0.7 for each dimension and the total scale), and acceptable test-retest reliability (ICC 0.73; 95% CI: 0.55-0.84). A sensibility was 80.0% and specificity 57.6% were found using a cutoff point of 10, indicating good discriminative validity (P<.05 for all cases). Additionally, positive correlations were found between the AQ-D and the Zarit and NPI scales, while negative correlations were observed with the Mini-mental and Yesavage scales.

Conclusion

The AQ-D is valid and reliable for screening anosognosia in Colombian patients with MND.

哥伦比亚严重神经认知障碍患者痴呆厌食症问卷的验证

目的探讨哥伦比亚重度神经认知障碍（MND）患者痴呆病感失认问卷（Anosognosia Questionnaire in Dementia, AQ-D）的效度和信度。方法采用认知访谈法和专家评比法对哥伦比亚MND患者的AQ-D量表进行调整和验证。共有189对参与者，包括护理人员和患者，被纳入研究并进行了AQ-D问卷调查。评估了结构效度、内部一致性、判别效度和并发效度、收敛效度和重测可行性。结果在验证性析因分析中探索了三个模型后，采用一个四维模型来评价AQ-D量表的效度。量表具有良好的内部一致性（Cronbach's alpha和McDonald's omega各维度及总量表均在0.7以上），重测信度可接受(ICC 0.73；95% ci: 0.55-0.84)。灵敏度为80.0%，特异性为57.6%，使用10的截断点，表明具有良好的判别效度(P<；所有情况都是05)。此外，iq - d与Zarit和NPI量表呈显著正相关，与Mini-mental和Yesavage量表呈显著负相关。结论AQ-D筛查哥伦比亚MND患者病感缺失是有效可靠的。
