Summary Background. Obstructive sleep apnea hypopnea syndrome is a clinical picture with multiple comorbidities and complications. Usually it is not diagnosed,therefore there must be tools that can identify patients at high risk. Among them the Berlin Questionnaire. Objective. Validate Berlin questionnaire in Colombia. Materials and methods. Individuals who attended sleep centers in Bogotá and college students were studied. Six phases: translation and back translation of the original Berlin Questionnaire, validating appearance (experts, n=14), internal consistency (n=212), and discriminant validity criteria (n=212) with parallel polysomnography, reproducibility (n=74). Results. Berlin Questionnaire has a sensitivity of 87%, specificity 70%, positive predictive value 98 %, negative predictive value 21 %, LR+ 2.9, LR- 18 and an area under the curve of 0,7856. Internal consistency was a Cronbach's alpha coefficient 0,7257. The reproducibility found at kappa of 0.8150 (Prob>Z=0,0000). Conclusions. Berlin Questionnaire is now adapted to urban living conditions in the Colombian adult population, it is sensitive, specific and has a high reproducibility and internal consistency, so that is reliable, valid and correlates with polysomnography in the form clinically and statistically significant.
