Traducción, adaptación y validación del inventario de burnout de Copenhagen para Perú
(Pontificia Universidad Católica del Perú, 2022-07-04)
The goal is to adapt and analyze the psychometric properties of the Copenhagen Burnout Inventory (CBI) in workers of the national domestic violence helpline (Peru). Two measurements were taken in the same population (n=160). Translation-back translation was applied. Internal consistency was assessed with Cronbach’s alpha, corrected Item-Total Correlation and omega coefficient. Test-retest was performed in the second measurement. Convergent validity was examined with Pearson correlations with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale. Confirmatory Factor Analysis confirmed that the three-correlated factor model has the best fit. Regarding reliability, adequate coefficients were found (alpha: >.82, omega: >.91 and intraclass correlation: > .66). The CBI scales are correlated with the Secondary Traumatic Stress Scale, the Perceived Stress Scale, and the Fear of Covid-19 Scale, and they are also significantly associated with self-reported health status, but only work-related burnout is associated with self-reported workload. As a result, the CBI shows excellent psychometric properties.

Pandemia y salud mental: predictores del miedo al coronavirus (COVID-19) en jóvenes y adultos peruanos
(Universidad de Lima, 2024-08-23)
The COVID-19 pandemic impacted the mental health of thousands of young people and adults, especially in its initial phase, since the disease was perceived as an uncertain and continuous threat, resulting in the fear of the coronavirus becoming dysfunctional, generating psychological discomfort. The principal aim of the study was to evaluate the psychosocial variables that predict fear of the coronavirus and its dimensions, in a sample of 384 Peruvian youth and adults, women (64.5%) and men (35.5%), between the ages of 18 and 67 (M= 26.36, SD=9.17). The predictor variables evaluated were Uncertainty, Stress, and the Use of the media, using for their measurement the IUS-12, the PSS-10 and the Scales of Use of the media and Fear of the coronavirus that belong to the Questionnaire of the Psychological Impact of the Coronavirus by Sandín et al. (2020). The results of the multiple linear regression analyzes revealed a prediction model of fear of the global coronavirus with a large effect size (R2 = .28, p < .001) and of medium magnitude in the models to predict its dimensions, thus evidencing the predictive capacity of intolerance towards uncertainty, stress, and frequent use of the media. Likewise, sex, educational level and employment were significant variables in the models, and it seems the women and those people who have a low educational level or do not have a job experience a greater fear of COVID-19.

Efecto del uso de un bioestimulante a base de algas marinas sobre el crecimiento y desarrollo del cultivo de habas (Vicia faba)
(2025-03-31)
En este estudio se evaluó la eficiencia de un bioestimulante a base de algas marinas sobre el crecimiento y desarrollo del cultivo de habas (Vicia faba). La investigación se realizó en condiciones controladas de invernadero y se evaluaron parámetros agronómicos como altura de la planta, número de hojas y vigor, utilizando un diseño completamente al azar con dos tratamientos (T1 con bioestimulante) y (T2 sin bioestimulante). La primera evaluación se realizó a los 11 días después de la siembra y, posteriormente se realizaron otras evaluaciones en un intervalo de 9 días. Los resultados demostraron que las plantas tratadas con bioestimulante presentaron un aumento significativo en la altura, pero no se encontraron diferencias estadísticamente significativas en el número de hojas ni el número de macollos. Estos hallazgos sugieren que los bioestimulantes pueden ser efectivos para promover el crecimiento vegetativo, aunque su impacto en otras características morfológicas es limitado. El uso de bioestimulantes a base de algas marinas podría ser una estrategia viable para mejorar la productividad de habas, promoviendo prácticas agrícolas más sostenibles.
