DOI: 10.9756/INT-JECSE/V14I1.221007 Received: 15.08.2021 Accepted: 10.11.2021 Abstract Currently, the International Health Organizations consider stress a morbidity and should be treated as a public health issue, even more so as a result of the health pandemic experienced. The university student was no stranger to this, suffering the so-called academic stress due to both academic and social factors. To determine the level of this, the SISCO university stress inventory was used, whose purpose was to identify attributes of stress that usually follow undergraduate and graduate students in the course of their university education. It consists of 30 items divided into three dimensions: stressful situations, symptoms (physical, psychological and behavioral reactions) and coping strategies. The results indicated that this inventory has good internal consistency in the total scale and in its dimensions. In terms of validity, the AFE and AFC proved that there are three factors considered in the theoretical model: symptoms, stressors and coping strategies, and the confirmatory analysis indicates an adequate fit for the academic stress model. Keywords: Stress, Behavior, Psychological Effects, Mental Health. Introduction The university institution has introduced potentially stress-provoking effects, with competitiveness being one of the most relevant factors (Polo, Hernández & Pozo, 1996). In the university, there are many students; however, there are few opportunities in the job market, that makes them aim to "be the best"; from another angle, to the extent of academic life, students are almost always imposed to university demands, excessive responsibility, continuous exams and practices, expositions and jobs that unwittingly generate stress, which is generally expressed as a result of frustrations caused by unmet needs (Huaquín & Loaiza, 2004; Barraza, 2004). The tension caused by stress is, to a certain extent, necessary for the development of the student's character; however, when stress exceeds ideal levels, it depletes the subject's energy, impairs performance and can damage Olga Lidia Solano Dávila 1 Luis Alberto Núñez Lira 2 Willy Valle Salvatierra 3 Wilberto Fernando Rubio Cabrera 4 Sergio Enrique Valle Ríos 5 Reliability and Validity Analysis of the Academic Stress Inventory in University Students
