Background: The Intensification of Job Demands Scale (IDS) is a multidimensional instrument designed to capture the phenomenon of work intensification that characterizes modern Western societies. However, in Spain the instrument has not been validated to assess this phenomenon. The aim of this study was to examine the psychometric properties of the IDS adaptation with a heterogeneous sample of Spanish workers. Method: The sample consisted of 722 Spanish workers (57.8% female, 42.2% male) who completed a survey between January and April 2022. Results: A five-factor correlated model, as in the original IDS, had an optimal fit with 15 items, and displayed invariance across gender, level of education, and organizational tenure. Reliability coefficients were all satisfactory, and scale adaptation showed evidence of convergent, discriminant, and incremental validity. Conclusions: The Spanish adaptation of the IDS is a valid, reliable measure for analyzing the phenomenon of work intensification and intensified job demands in Spain.
Antecedentes: La Escala de Intensificación de las Demandas Laborales (IDS) es un instrumento multidimensional diseñado para captar el fenómeno de la intensificación laboral que caracteriza a las sociedades occidentales modernas. Sin embargo, en España, el instrumento no ha sido validado para evaluar este fenómeno. Por ello, el objetivo de este estudio fue examinar las propiedades psicométricas de la IDS para su adaptación a una muestra heterogénea de trabajadores españoles. Método: La muestra estuvo formada por 722 trabajadores españoles (57,8% mujeres) que completaron una batería de cuestionarios entre enero-abril de 2022. Resultados: Un modelo correlacionado de cinco factores, como en la IDS original, tuvo un ajuste óptimo con 15 ítems, y mostró invarianza en género, nivel de estudios y antigüedad dentro de la organización. Los coeficientes de fiabilidad fueron satisfactorios, y la adaptación de la escala mostró evidencias de validez convergente, discriminante e incremental. Conclusiones: La adaptación española de la IDS es una medida válida y fiable para analizar el fenómeno de la intensificación laboral en España.
