- W4387675308 abstract "Establecer la validez y confiabilidad del cuestionario de anosognosia en demencia (AQ-D) en personas con diagnóstico de trastorno neurocognitivo mayor (TNM) en la población colombiana. La escala AQ-D se adaptó y validó para pacientes con TNM en Colombia mediante entrevistas cognitivas y revisión de expertos. Se incluyeron 189 pares de participantes a quienes se les aplicó el AQ-D para el cuidador y el de paciente, respectivamente. Se evaluó validez estructural, consistencia interna, validez de constructo discriminativo y de criterio concurrente, validez convergente y confiabilidad test-retest. Después de explorar 3 modelos en el análisis factorial confirmatorio, se adoptó un modelo de 4 dimensiones para evaluar la validez de la escala AQ-D. La escala tuvo una buena consistencia interna (alfa de Cronbach y omega de McDonald superiores a 0,7 para cada una de las dimensiones y para la escala total) y una reproducibilidad test-retest aceptable (ICC: 0,73; IC95%: 0,55-0,84). Se encontró una sensibilidad del 80,0%, una especificidad del 57,6%, con un punto de corte de 10, buena validez discriminativa (p < 0,05 para todos los casos). Además, se encontraron correlaciones positivas entre AQ-D y las escalas Zarit y NPI, y correlaciones negativas con Mini mental y Yesavage. El AQ-D es válido y confiable para el tamizaje de la anosognosia en pacientes colombianos con TNM. 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. 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. 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. The AQ-D is valid and reliable for screening anosognosia in Colombian patients with MND." @default.
