Validation of pediatric sleep questionnaire translated in Urdu language
Introduction: Obstructive Sleep Apnea Syndrome (OSAS) is an intrinsic sleep disturbance which can have serious health consequences if left untreated. Pediatric Sleep Questionnaire-sleep related breathing disorder (PSQ-SRBD) scale is a valid and reliable tool for screening of patients with a predisposition towards this condition. This study aimed to translate and validate the questionnaire to Urdu language; so that it may be used in clinical settings by pediatricians, orthodontists, general dentists and general physicians alike.
Material and methods: Established guidelines by Beaton et al were used for translation of the questionnaire. Pearson correlation and interclass correlation coefficient were applied to determine test-retest reproducibility. Cronbach alpha and exploratory factor analysis were used to determine the internal consistency and construct validity of the translated questionnaire.
Results: The results showed good test-retest reproducibility. Cronbach alpha was 0.651 indicating high internal consistency.
Conclusions: PSQ-SRBD has been successfully translated and cross-culturally adapted to Urdu language; and has been found to be valid and reliable statistically.
