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.

Estrés académico, proceso multifactorial complejo que alcanza sus grados más elevados a nivel universitario y que para realizar intervenciones efectivas, necesita de instrumentos válidos y fiables para medirlo. El objetivo de este trabajo fue evaluar las propiedades psicométricas de una versión adaptada del inventario SISCO del estrés académico, denominada SISCO-II, destinada a medir estrés académico en estudiantes universitarios. Se aplicó el instrumento a 1.126 estudiantes universitarios de tres universidades chilenas. El análisis factorial confirmatorio mostró buen ajuste a la estructura propuesta de cuatro factores (Estresores, Reacciones físicas y psicológicas, Reacciones del comportamiento social y Afrontamiento). La medida de estrés académico queda constituida por estresores, reacción total (Reacciones físicas, psicológicas y del comportamiento social) y estrategias de afrontamiento. Los resultados avalan la utilidad de SISCO-II para uso diagnóstico y evaluación de intervenciones, siendo una escala válida y confiable.
