espanolObjetivo. Analizar las propiedades psicometricas de las escalas de la Bateria UNIPSICO que permiten evaluar los factores psicosociales de recursos del contexto de trabajo. Metodos. La muestra estuvo formada por 2564 participantes, 1391 trabajadores de centros de atencion a personas con discapacidad psiquica, y 1173 docentes de secundaria de la Comunidad Valenciana. La recogida de datos se realizo mediante las escalas de la Bateria UNIPSICO que evaluan factores psicosociales de recursos del lugar de trabajo (26 items) que se agrupan en 4 escalas: Disponibilidad de recursos, Apoyo social en el trabajo, Retroinformacion y Autonomia. Se realizaron analisis de items, validez de constructo con analisis factorial confirmatorio, analisis de fiabilidad segun alfa de Cronbach, y validez predictiva con regresiones stepwise. Resultados. Todos los items presentaron valores adecuados de asimetria y fiabilidad del item. Las cuatro escalas presentaron valores de asimetria dentro del intervalo +/-1. El modelo factorial hipotetizado de cuatro factores presento un ajuste adecuado a los datos (GFI = 0,922, NNFI = 0,898, CFI = 0,912, RMSEA = 0,059). Las cuatro escalas alcanzaron valores de fiabilidad alfa de Cronbach superiores a 0,80. Segun los resultados de regresion stepwise todas las variables fueron predictores significativos de problemas psicosomaticos. Conclusion. Las cuatro escalas evaluadas son validas y fiables. Las escalas presentaron validez predictiva sobre problemas psicosomaticos derivados del trabajo. Las escalas analizadas constituyen un instrumento valido y fiable para evaluar los factores psicosociales de recursos en el trabajo EnglishPurpose. To analyze the psychometric properties of the UNIPSICO questionnaire' scales designed to evaluate psychosocial resource factors at work. Methods. The sample consisted of 2564 participants; 1391 were employees working with people with intellectual disability and 1173 were high school teachers from the Valencian Community. Data were collected through use of the UNIPSICO questionnaire, which includes scales designed to measure psychosocial resource factors in the workplace. This instrument consists of 26 items distributed in 4 scales: resources at work, work social support, feedback, and autonomy. Data were analysed to test item validity, construct validity by confirmatory factor analysis (CFA), reliability by Cronbach’s alpha, and predictive validity by stepwise regression analysis. Results. For all items skewness and reliability values were adequate. The four scales followed the normal distribution, with skewness values ranging between +1 and -1. The results of the CFA confirmed the hypothesised four-factor structure. The hypothesised model showed a good data fit (GFI = 0,922, NNFI = 0,898, CFI = 0,912, RMSEA = 0,059). Scale score reliability coefficients for the five scales showed values above 0.80. Stepwise regression analysis demonstrated all variables were significant predictors of psychosomatic disorders. Conclusions. The validity and reliability of the four scales were satisfactory. In addition, the scales offer predictive validity for the study of work-related psychosomatic disorders. The UNIPSICO scales analyzed are an adequate tool to evaluate psychosocial resource factors at work.
