Abstract
OBJECTIVE: Obstructive sleep apnea (OSA) is a comorbid condition with obesity that can produce deleterious effects on children's health and well-being. Unfortunately, valid instruments for screening OSA in obese Thai children are limited. This study aimed to translate and cross-culturally adapt, from English to Thai, the Sleep-Related Breathing Disordered-Pediatric Sleep Questionnaire (SRBD-PSQ) and to determine its psychometric properties. METHODS: The SRBD-PSQ was translated into Thai and cross-culturally adapted. It was administered to 62 parents of obese children and adolescents 7-18 years of age who had polysomnographically confirmed OSA. The psychometric properties including validity, reliability, and diagnostic accuracy were examined. RESULTS: The Thai SRBD-PSQ possessed excellent content validity index for scale (S-CVI = 0.95). An acceptable internal consistency (cronbach's α ≥ 0.7) and good to excellent test-retest reliability (intraclass correlation coefficients [ICCs] = 0.82-0.90) of the Thai SRBD-PSQ and subdomain were observed. There was a significant correlation between the SRBD scale and polysomnography (PSG) indices: apnea-hypopnea index (AHI) and oxygen desaturation index (ODI) (r = 0.35, p < 0.01, and r = 0.27, p < 0.05, respectively). The Thai SRBD-PSQ had an area under the curve of 0.71 (p < 0.05) with a sensitivity of 72% and a specificity of 54%. CONCLUSION: The Thai SRBD-PSQ is a reliable and valid instrument for use in obese children with OSA. However, the Thai SRBD-PSQ should be used in combination with other investigations.
