Methods: it was completed by interview and individual filling out of the forms in 605 people. Descriptive measures were used for items, scales and groups; internal correspondence between items and their scales, and inter and intra-evaluator reliabilities were calculated. Results: omitted data ranged from 0% to 1,5%, itemscale correlations were over 0,48, reliability was higher than 0,70. There were no differences in scales scores according to type of application. Inter-evaluator reliability was higher than 0,80; test-retest was over 0,70, showing no significant differences in the two applications. Discussion: SF-36 questionnaire is reliable to evaluate health life quality in Colombian adults after its linguistic adaptation.
