Translation and validation of the Thai Version of the Japanese Sleep Questionnaire for Preschoolers (JSQ-P).

This study aimed to translate and validate the Japanese Sleep Questionnaire for Preschoolers (JSQ-P) into a Thai version and to evaluate factors associated with sleep problems in preschoolers. The cross-cultural adaptation of JSQ-P into Thai version of JSQ-P (TH-JSQ-P) was performed including forward translation, reconciliation, backward translation, and final approval by the original creator. Children aged 2-6 years from community and clinical settings were enrolled. The TH-JSQ-P was completed by parents of preschool children twice within 10-14 days to assess its reliability and validity. Six validity tests including face validity, content validity, structural validity, construct validity, criterion validity and predictive validity were assessed. Demographic data, Epworth sleepiness scale (ESS), medical and behavior problems, and socioeconomic status were collected for analysis. A total of 2613 participants completed the TH-JSQ-P, with 1207 completing it twice to assess test-retest reliability. The TH-JSQ-P had good internal consistency reliability and test-retest ability with Cronbach's alpha value of 0.898 and intraclass correlation coefficient of 0.814. The content validity was acceptable. The ESS had correlation with sleep problems in almost all subscales except for sleep habit. The TH-JSQ-P is a valid and reliable instrument for evaluating sleep problems in preschool children in Thailand. It has the potential to be extensively utilized to screen for sleep problems, thereby enabling healthcare professionals to identify them early and implement prompt management.

Psychometric properties and population-based score distributions of the Japanese Sleep Questionnaire for Preschoolers.

We aimed to present psychometric properties and describe the score distributions of the Japanese Sleep Questionnaire for Preschoolers (JSQ-P), a guardian-reported survey questionnaire for assessing sleep disturbances and problematic sleep habits among preschool children. Guardians of 2998 toddlers in three communities and guardians of 102 patients diagnosed with sleep disorders in two clinics completed the JSQ-P. Exploratory factor analysis (EFA) revealed the 10 domains of the JSQ-P to be similar to our previous small-scale study and confirmed the robustness of the JSQ-P. The JSQ-P showed acceptable internal consistency; α coefficients ranged from 0.622 (insufficient sleep) to 0.912 (restless legs syndrome [RLS], motor) for the community sample and 0.696 (insufficient sleep) to 0.959 (RLS, motor) for the clinical sample. The score differentiations between the community and clinical samples associated with RLS, obstructive sleep apnea syndrome (OSAS), morning symptoms, parasomnias, excessive daytime sleepiness, and daytime behaviors were demonstrated in our study. The distributions of percentile T scores for each subscale and age and gender differentiation of scores also were evaluated. We confirmed that the JSQ-P is a valid and reliable instrument to evaluate Japanese sleep habits using a large population-based sample. The JSQ-P may be useful in both clinical and academic settings.
