An谩lisis psicom茅trico y adaptaci贸n de la versi贸n chilena del instrumento SUSESO/ISTAS21 para medir el riesgo psicosocial en trabajadores de obras civiles en un proyecto de construcci贸n
It has been identified that one of the most important causes of work absenteeism for health reasons is exposure to psychosocial factors. These psychosocial factors have also been related to different conditions to the workers, such as health gastrointestinal, dermatological, and endocrinological disorders, among others and to certain behaviors that are related to health, such as the habit of smoking, the consumption of alcohol, drugs, narcotics and sedentary lifestyle. The purpose of this article is to explain the psychometric properties of the SUSESO/ISTAS21 Chilean version instrument, adapted for a sample of 209 workers belonging to the civil works area of a construction project. The sample included male and female workers. The complete version of the instrument has 89 items distributed in 5 dimensions, while the adapted version, after having carried out the exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA), was made up of 19 items that had a factor load greater than 0.7 distributed in four factors or dimensions. From the analysis carried out, good correlations were found, the composition in factors is similar to that of the original instrument, and the validity and reliability of the adapted instrument were obtained with Cronbach's alpha values between 0.70 and 0.90, necessary for its application.Se ha identificado que una de las causas m谩s importantes del ausentismo laboral relacionado con temas de salud es la exposici贸n a factores psicosociales. Estos han sido vinculados con diferentes afecciones a la salud de los trabajadores, como trastornos gastrointestinales, dermatol贸gicos, endocrinol贸gicos, entre otros. Y, tambi茅n, con determinadas conductas que se relacionan con la salud como, por ejemplo, el h谩bito de fumar; el consumo de bebidas alcoh贸licas, drogas, estupefacientes; y el sedentarismo. Este art铆culo tiene como fin explicar las propiedades psicom茅tricas del instrumento SUSESO/ISTAS21 en su versi贸n chilena, adaptado para una muestra de 209 trabajadores pertenecientes al 谩rea de obras civiles de un proyecto de construcci贸n. La muestra incluy贸 trabajadores hombres y mujeres. La versi贸n completa del instrumento posee 89 铆tems distribuidos en 5 dimensiones; mientras que, la adaptada, luego de haberse realizado el an谩lisis factorial exploratorio (AFE) y el an谩lisis factorial confirmatorio (AFC), qued贸 conformada por 19 铆tems que tuvieron una carga factorial mayor de 0.7 distribuidas en cuatro factores o dimensiones. En el an谩lisis realizado, se encontraron buenas correlaciones: la composici贸n en factores es similar al del instrumento original lo que evidencia una validez factorial, y se obtuvo la fiabilidad del instrumento adaptado con valores del alfa de Cronbach entre 0.70 y 0.90, necesario para su aplicaci贸n
