INTRODUCTION: Obstructive Sleep Apnea Syndrome (OSAS) or Apnea-Hypoapnea Syndrome (SAHS) is one of the most prevalent sleep disorders in the general population. It is associated with an increase in the prevalence of difficult orotracheal intubation and postoperative complications. The application of validated early detection tests, such the STOPbang test in English (STBC), is recommended; a test of high methodological quality, sensitivity and specificity in the early detection of SAHS in both surgical and general populations.

OBJECTIVE: The validation, translation, cross-cultural adaptation of the STBC to the Spanish population.

MATERIAL AND METHODS: The transcultural adaptation of the STBC to Spanish was carried out and a subsequent validation study with 77 consecutive patients was carried out. The statistical analysis evaluated the reliability, validity and feasibility of the translated and culturally adapted version.

RESULTS: 44% of women and 56% of men were included, with a mean age of 53.58 ± 12.88 years. The reliability results were: a Cronbach’s Alpha Coefficient of 0.767, a Pearson correlation r = 0.777 (P < .001) and a Sperman correlation rho = 0.455 (P = .044). The feasibility of the study was 100%. Criterion validity was evaluated using the Kappa coefficient, which was 0.444. For a score >3 of the questionnaire adapted to Spanish, the results of sensitivity, specificity according to the different cut-off levels of the apnea hypopnea index (AHI) >5, >15, >30) were: Sensitivity 87%, 91% and 100% respectively and Specificity of 50%, 31% and 22%.

CONCLUSIONS: The STBC questionnaire translated, adapted and validated into Spanish, evaluated in the present study, is reliable and valid with respect to the original design of the questionnaire. It is a useful tool that is easy to understand and implement, which can be used rigorously to stratify surgical risk and carry out adequate perioperative planning of those patients at risk of SAHS.
