title: Adaptation and Validation of the Spanish Version of OSA-18, a Quality of Life Questionnaire for Evaluation of Children with Sleep Apnea-Hypopnea Syndrome.
abstract: OBJECTIVE
  To analyze the reliability and validity of the Spanish version of the OSA-18 quality of life questionnaire in children with apnea-hypopnea syndrome (SAHS).
  
  
  METHODS
  Children with suspected SAHS were studied with polysomnography (PSG) before and after adenotonsillectomy (AA). Age, gender, clinical data, PSG, anthropometric data, and Mallampati and Brodsky scales were analyzed. OSA-18 was administered at baseline and 3-6months post AA. After translation and backtranslation by bilingual professionals, the internal consistency, reliability, construct validity, concurrent validity, predictive validity and sensitivity to change of the questionnaire was assessed.
  
  
  RESULTS
  In total, 45 boys and 15 girls were evaluated, showing BMI 18±4, neck 28±5, Brodsky (0: 7%; <25%: 12%; 25-50%: 27%; >50 to <75%: 45%; >75%: 6%), AHI 12±7 pre AA. Global Cronbach alpha was 0.91. Correlations between domains were significant except for emotional aspects, although the total scores correlated with all domains (0.50 to 0.90). The factorial analysis was virtually identical to the original structure. The total scores showed good correlation for concurrent validity (0.2-0.45). With regard to predictive validity, the questionnaire adequately differentiated levels of severity according to Mallampati (ANOVA P=.002) and apnea-hypopnea index (ANOVA P=.006). Test-retest reliability was excellent, as was sensitivity to change, both in the total scores (P<.001) and in each domain (P<.001).
  
  
  CONCLUSIONS
  The Spanish adaptation of the OSA-18 and its psychometric characteristics suggest that the Spanish version is equivalent to the original and can be used in Spanish-speaking countries.
