ABSTRACT
Objectives: To examine the association between psychiatric and non-psychiatric comorbidity and 28-day mortality among patients with psychiatric disorders and COVID-19. Methods: Multicenter observational retrospective cohort study of adult patients with psychiatric disorders hospitalized with laboratory-confirmed COVID-19 at 36 Greater Paris university hospitals (January 2020-May 2021) (n=3,768). First, we searched for different subgroups of patients according to their psychiatric and non-psychiatric comorbidities through cluster analysis. Next, we compared 28-day all-cause mortality rates across the identified clusters, while taking into account sex, age, and the number of medical conditions. Results: We found five clusters of patients with distinct psychiatric and non-psychiatric comorbidity patterns. Twenty-eight-day mortality in the cluster of patients with mood disorders was significantly lower than in other clusters. There were no significant differences in mortality across other clusters. Conclusion: All psychiatric and non-psychiatric conditions may be associated with increased mortality in patients with psychiatric disorders and COVID-19. The lower risk of death among patients with mood disorders might be in line with the potential beneficial effect of certain antidepressants in COVID-19, but requires further research. These findings may help identify at-risk patients with psychiatric disorders who should benefit from vaccine booster prioritization and other prevention measures.
ABSTRACT
Introduction: Reading Comprehension skills are fundamental to the academic performance of university students. These abilities are not innate; therefore, systematic training is required before entering university. The main objective of this study was to evaluate the reading comprehension skills of Chilean University Students. Method: A sample of 579 students participated in the study, responding to four texts that comprise the Reading Comprehension Strategies for University Students (ELCU). An automated platform was used to apply and correct the test with immediate results and feedback. The tool allowed the use of a broad and representative sample of the various regions of Chile. The ELCU was developed using a cognitive diagnostic assessment (CDA) considering cognitive, metacognitive and linguistic strategies. The ana-lyses were performed using two different approaches: The Linear Logistic Test Model (LLTM) and the deterministic inputs, noisy "and" gate (DINA) model. Results: The rejection of the LLTM implies that the strategies do not differ in cognitive complexity (difficulty) while the adequate goodness of fit to the DINA model allows to characterise the students according to their reading abilities. Conclusion: The ELCU test provides reliable and valid information on the reading comprehension ability and metacognitive awareness of university students.
Introducción: Las habilidades de comprensión lectora son fundamentales para el rendimiento académico de los estudiantes universitarios. Estas habilidades no son innatas; por tanto, se requiere una formación sistemática antes de ingresar a la universidad. El objetivo principal de este artículo fue evaluar las habilidades de comprensión lectora de estudiantes universitarios chilenos. Método: En el estudio participó una muestra de 579 estudiantes que respondieron cuatro textos que componen las Estrategias de Comprensión Lectora para Estudiantes Universitarios (ELCU). Se utilizó una plataforma automatizada para aplicar y corregir la prueba con resultados y retroalimentación inmediatos. La herramienta permitió utilizar una muestra amplia y representativa de las distintas regiones de Chile. ELCU fue desarrollado mediante evaluación diagnóstica cognitiva (CDA) considerando estrategias cognitivas, metacognitivas y lingüísticas. Los análisis se realizaron mediante dos aproximaciones diferentes: The Linear Logistic Test Model (LLTM) y the Deterministic Inputs, Noisy "and" Gate (DINA) model. Resultados: El rechazo al modelo LLTM implica que las estrategias no difieren en complejidad cognitiva mientras que la adecuada bondad de ajuste al modelo DINA permiten caracterizar a los estudiantes según sus habilidades lectoras. Conclusión: La prueba ELCU permite obtener información confiable y válida sobre la capacidad de comprensión lectora y la conciencia metacognitiva de los estudiantes universitarios.
ABSTRACT
Se analizan los componentes básicos para la adquisición de la lectura en castellano mediante la aplicación del modelo logístico lineal de Fisher (Linear Logistic Test Model [LLTM]). Participaron en el estudio 245 niños y niñas de edades comprendidas entre los 4 y los 9 años a los que se administró una extensa batería diseñada para evaluar distintos procesos básicos para la lectura (PROBALES). Se aplicaron técnicas de análisis factorial para seleccionar un subconjunto de ítems que mostrasen ajuste al modelo de Rasch. El LLTM permitió confirmar la validez del modelo teórico según el cual el aprendizaje de la lectura descansa en el desarrollo de tres habilidades básicas: reconocimiento de palabras, conciencia fonológica y comprensión de la lectura. Se muestra la capacidad predictiva del modelo mediante análisis discriminante, y se constata que se clasificó correctamente en su curso escolar al 68% de los participantes.
The basic components for the acquisition of reading in Spanish are analyzed by using the Fisher Linear Logistic Test Model (LLTM). An extensive battery designed to assess different Basic Processes for Reading (PROBALES, acronym in Spanish) was applied to 245 children aged 4 to 9. Factor analysis techniques were used to select a subset of items that would adjust to the Rasch model. The LLTM confirmed the validity of the theoretical model which states that reading acquisition relies on the development of three basic skills: word recognition, phonological awareness, and reading comprehension. The theoretical model's predictive ability is shown by discriminant analysis, thereby confirming that 68% of participants were correctly classified in their school grade.
