نبذة مختصرة : The aim was to analyze the psychometric properties of the objective section of the Integral Quality of Life Scale in a sample of 102 personswith intellectual disabilities, 61 men (59.8 %) and 41 women (43.7 %), aged between 18 and 58 years (M = 24.05, SD = 9.57). Of theparticipants, 38 (37.3 %) have a mild disability, 46 (45.1 %) have a moderate disability, and 18 (17.6 %) have a severe disability, as reportedby the family and institutions. The confirmatory factor analysis conducted reveals that this presents a five-factor structure with an empirically important general factor (bifactor model). Furthermore, regarding the reliability of the construct by coefficient Rho an indicator of .952 wasobtained, and based on the model bifactor reliability factor was estimated through the omega coefficient, obtaining an indicator of .951 to thetotal scale, .888 for the «Self-Determination», .643 factor for the «Social Inclusion», .859 factor for the «Laboral Wellbeing» factor, .918 forthe «Material Wellbeing» and .866 for factor factor «Emotional and physical Wellbeing». We conclude that the objective scale has adequateto continue validation studies using other strategies, supporting its use as a tool for assessing the quality of life in adults with intellectualdisabilities. ; El objetivo fue analizar las propiedades psicométricas de la sección objetiva de la integral de calidad de vida en una muestra de 102 personascon discapacidad intelectual, 61 varones (59.8 %) y 41 mujeres (43.7 %), con edades comprendidas entre 18 y 58 años (M = 24.05; DE= 9.57).

El análisis factorial confirmatorio realizado revelaque dicha discapacidad presenta una estructura pentafactorial con un factor general empíricamente importante (modelo bifactor).
