Abstract

fetched live from OpenAlex

Introducción. La esquizofrenia es un trastorno mental que posee múltiples dimensiones sintomáticas y las alteraciones cognitivas son características cardinales en la evolución del trastorno. El uso de clinimetría para evaluar dichas deficiencias puede aportar información en la investigación en este campo. Objetivo. Determinar la validez y confiabilidad de la Escala de Evaluación Cognitiva Montreal (MoCA) para la evaluación del déficit cognitivo en pacientes con el diagnóstico de esquizofrenia. Material y métodos. Se evaluaron cien pacientes con diagnóstico de esquizofrenia reclutados en la Clínica de Esquizofrenia del Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz. Se aplicaron las escalas de MoCA, MMSE y PANSS para la valoración de las funciones cognitivas. Se estableció la confiabilidad del MoCA con el Alfa de Cronbach y se estableció su validez concurrente con el MMSE y la subescala cognitiva de la PANSS. Resultados. De acuerdo al MMSE (con ajuste de escolaridad) el 8% de los pacientes fueron clasificados con deterioro cognitivo en contraste con el puntaje total del MoCA que reporto 69% de la muestra con deterioro cognitivo. La escala MoCA obtuvo una confiabilidad (Alfa de Cronbach=0.71) similar a la observada por el MMSE (?=0.70) y adecuada validez concurrente. Conclusiones. La MoCA es un instrumento confiable y válido para establecer la presencia de deterioro cognitivo leve en pacientes con esquizofrenia, sencillo y de fácil aplicación en la práctica clínica psiquiátrica cotidiana.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
