Objective: Validate the KIDSCREEN-27 for parents in the metropolitan area of Medellin, Colombia, including the Social Acceptance (SA) subscale of KIDSCREEN-52, as it evaluates the effect of bullying in Life Quality of children. Methods: The study population was made up by parents of children between 8 and 18, from Medellin and its metropolitan area. A sample of 1,150 parents was estimated according to the different psychometric properties to be measured. Construct validation was made by comparing the mean scores between groups of high and low socioeconomic conditions. The content validity and the measurement of reliability were verified by internal consistency and test-retest stability. The parent-child agreement was also measured. Results: The internal consistency was adequate (Cronbach alpha 0,76-0,83). Parents of children with better socio-economic status had higher scores in all dimensions (p<0,05). Scores were higher among healthy children. Women had lower scores than men, while children registered higher scores than adolescents. The intra-class correlation coefficient for the reliability assessment was above 0.7 in all dimensions, except in School Environment-SE- (ICC 0,6-0,92). The parent-child agreement reached moderate and good levels (ICC 0,49-0,69). The exploratory factorial analysis, including social acceptance subscale, registered eight dimensions, four of which in agreement with the original questionnaire: Physical activity, SE, Social Support, and SA subscale. Conclusions: KIDSCREEN-27 for parents is a valid and reliable instrument to be used in the Colombian context.
