El presente informe contiene los resultados del proceso de validación psicométrica de un conjunto de instrumentos de diagnóstico diseñados para evaluar cuatro constructos psicológicos considerados como efectos o consecuencias de la presencia de diversos factores psicosociales propios de los ambientes de organizaciones laborales. Los constructos aludidos son salud, bienestar, desempeño y crecimiento psicológico, entendidos como variables dependientes influenciadas por riesgos y protectores psicosociales propios del contexto laboral, del estilo personal del trabajador y de sus juicios y percepciones de las realidades laborales. Se realizaron análisis de ítems (discriminación, correlación ítem-test, peso factorial), análisis factoriales exploratorios y confirmatorios para evaluar su validez de construcción y cálculos de su confiabilidad por los métodos Alfa de Crombach y Dos Mitades. Los análisis evidenciaron apropiados niveles de validez y confiabilidad en la mayoría de los instrumentos, aunque también se encontraron algunas deficiencias en la capacidad de discriminación de algunos reactivos. Se discuten los resultados y se presentan sugerencias sobre su uso.AbstractThe results of a psychometric validation process of seven questionnaires are presented in this writing. Those instruments were design to measure four constructs related to consequences or effects of psychosocial factors on individual workers: health, wellbeing, performance and psychological growth. Such factors are considered dependent variables influenced by a set o independent variables such as the work context, worker´s individual style and perceptions of the different organizational realities. Item analysis was carried out (discrimination, item-test correlations and item factor loading), exploratory and confirmatory factor analysis and reliability estimations. Such analyses evidenced convenient levels of validity and reliability, although items of some instruments were unable to discriminate properly and other tests failed to be reliable enough. Resultas are discussed and suggestions offered.
