RESUMO
Resumen: Los estudios superiores representan el punto culminante del estrés académico, proceso multifactorial complejo, con alta carga de trabajo. El inventario SISCO del estrés académico posee buenas propiedades psicométricas para sus subescalas de Estresores, Sintomatología y para la puntuación media total, no así para la subescala de Afrontamiento. El objetivo de este artículo es corroborar lo reportado previamente en base a un análisis psicométrico completo. En 1126 estudiantes universitarios, se obtuvieron buenas propiedades psicométricas para las subescalas de Estresores y Sintomatología, con un buen ajuste en el análisis factorial confirmatorio, en base a una estructura de cuatro factores. La subescala de Sintomatología quedó conformada por las subescalas Reacciones físicas y psicológicas y por Reacciones del comportamiento social. La subescala de Afrontamiento mantiene propiedades psicométricas deficientes. La puntuación para el total de los ítems del instrumento muestra buenas propiedades psicométricas (alfa de Cronbach y omega de 0.820 y 0.860, respectivamente). Se corrobora lo reportado previamente, avalándose la necesidad de más estudios, y la modificación del instrumento, en especial la subescala de Afrontamiento.
Abstract: Higher education represents the peak of academic stress, a complex multifactorial process with a high workload. The SISCO academic stress inventory has good psychometric properties for its subscales Stressors, Symptomatology and for the whole instrument, but not for the Coping subscale. The aim of this paper is to corroborate previous reports based on a full psychometric analysis. In 1,126 university students, good psychometric properties were obtained for the Stressors and Symptomatology subscales, with a good fit in the confirmatory factor analysis, based on a four-factor structure. The Symptomatology subscale consisted of the subscales Physical and Psychological Reactions and Social Behavioural Reactions. The Coping subscale maintains poor psychometric properties. The complete scale score shows good psychometric properties (Cronbach's alpha and omega of 0.820 and 0.860, respectively). This corroborates previous reports and supports the need for further study and modification of the instrument, especially the Coping subscale.

Academic stress is an emotion that students experience during their time at the university, sometimes causing physical and mental health effects. Because of the COVID-19 pandemic, universities worldwide have left the classroom to provide the method of teaching virtually, generating challenges, adaptations, and more stress in students. In this pilot study, a methodology for academic stress detection in engineering students at the University of Pamplona (Colombia) is proposed by developing and implementing an artificial electronic nose system and the galvanic skin response. For the study, the student's stress state and characteristics were taken into account to make the data analysis where a set of measurements were acquired when the students were presenting a virtual exam. Likewise, for the non-stress state, a set of measurements were obtained in a relaxation state after the exam date. To carry out the pre-processing and data processing from the measurements obtained previously by both systems, a set of algorithms developed in Python software were used to perform the data analysis. Linear Discriminant Analysis (LDA), K-Nearest Neighbors (K-NN), and Support Vector Machine (SVM) classification methods were applied for the data classification, where a 96 % success rate of classification was obtained with the E-nose, and 100 % classification was achieved by using the Galvanic Skin Response.
RESUMO
OBJECTIVE: To evaluate the factorial structure and internal consistency of SISCO inventory of academic stress in medical students.. METHODS: The cross-sectional study was conducted at the School of Medicine, University of Concepcion, Chile, in 2014, and comprised second and third year students.Exploratory factor analysis was carried out to determine the reliability of each of the dimensions of SISCO inventory. Descriptive and correlational analyses were also conducted. RESULTS: Of the 155 students, 121(78.1%)were female. The overall mean age was 20.5+/- 1.55 years (range: 18.9-32.2 years). Of the total, 61(39.4%) students were in the nursing programme, 10(6.5%) in speech therapy, 16(10.3%) in kinesiology, 10(6.5%) in medicine, 20(12.9%) in midwifery and 38(24.4%) in medical technology.For stressor, somatisation and coping dimensions, a factor was identified, with Cronbach's alpha values of 0.76, 0.86 and 0.52, respectively. Correlation could only be established between the first two dimensions. CONCLUSIONS: Stressors and somatisation dimensions of the SISCO inventory of academic stress were found to be validity and reliabile.
