Background. Currently there are several instruments to assess the quality of life of people with intellectual disabilities, but none of them has been adapted and validated for their usage in Colombian population. The INICO - FEAPS Scale is an instrument that has shown sufficient evidence of validity and reliability in Spanish population with intellectual disabilities, which permits to carry out evidence-based practices by evaluating personal outcomes related to quality of life. Objective. To adapt the INICO-FEAPS Scale to be used in Colombian population with intellectual disabilities and to analyze its properties in terms of validity and reliability. Materials and Methods. In this instrumental study participated three expert judges, 602 people with intellectual disabilities and 693 key informants. A linguistic and a contextual adaptation to Colombian population with intellectual disability were performed. Evidence of content validity and a construct was performed. Reliability was analyzed in terms of internal consistency, intra-rater and inter-rater reliability. Results. The relevance mean score for other people report was 4.88/5.0(SD=0.16), while for self-report was 4.98/5.0 (SD=0.03). The adequacy mean for the former was 3.74/5.0 (SD=0.46) and for the latter was 4.43/5.0 (SD=0.57). Confirmatory factor analysis demonstrates a better goodness-of-fit to a hierarchical factorial second order model where the eight dimensions of the Schalock and Verdugo model are grouped in a second order, which corresponds to the quality of life. Internal consistency for both forms was excellent -Cronbach's alpha 0.915 and 0.931-. In general, all dimensions of other people report showed better values of Cronbach's alpha than the self-report subscale. Best intra-rater than inter-rater reliability was demonstrated and only one item showed an insignificant agreement (Kappa <0.21) in both tests. Conclusion. The INICO- FEAPS scale adapted for Colombian population with intellectual disabilities shows adequate levels of validity and reliability.
