Insights
The validated Japanese Child's Sleep Habits Questionnaire (CSHQ-J) effectively screens pediatric sleep disorders. Co-sleeping, supplemental sleep, and child's age impact scores.
Area of Science:
- Pediatric Sleep Medicine
- Psychometrics
- Child Health
Background:
- Pediatric sleep disorders are prevalent and impact child development.
- Validated screening tools are crucial for early detection and intervention.
- The Child's Sleep Habits Questionnaire (CSHQ) is a widely used tool, necessitating culturally adapted versions.
Purpose of the Study:
- To validate the Japanese version of the Child's Sleep Habits Questionnaire (CSHQ-J).
- To identify factors influencing the CSHQ-J total score in a Japanese pediatric population.
- To establish the utility of the CSHQ-J as a screening tool for pediatric sleep disorders.
Main Methods:
- Cross-sectional study involving 3158 children (aged 4-12 years) and their parents/guardians.
- Data collection included CSHQ-J, Pittsburgh Sleep Quality Index, and demographic/clinical information.
- Statistical analyses included exploratory/confirmatory factor analysis, internal consistency (Cronbach's α), and multivariate analysis.
Main Results:
- Analysis of 1688 participants aged 4-10 years. CSHQ-J subscale internal consistency ranged from 0.43 to 0.68.
- Confirmatory and exploratory factor analyses did not converge.
- Multivariate analysis identified co-sleeping, supplemental sleep, and child's age as significant factors influencing CSHQ-J scores. Present illness, particularly adenoids, also showed influence.
Conclusions:
- The CSHQ-J demonstrates adequate internal consistency and is a valuable tool for screening pediatric sleep disorders.
- Factors such as supplemental sleep, co-sleeping habits, and child's age are important considerations when interpreting CSHQ-J results.
- The CSHQ-J facilitates the identification of sleep problems in Japanese children.
Subject:
This study aimed to validate the Japanese version of the Child's Sleep Habits Questionnaire (CSHQ-J) and identify which factors affect the CHSQ-J total score.
Methods:
The participants were 3158 children (aged 4-12 years) and their parent/guardian, as community samples from large, medium-sized, and small cities. Each parent/guardian filled in the questionnaire set (CSHQ-J, Pittsburgh Sleep Quality Index, demographic data: family structure, sleep environment, participants' present illness, and economic information); we also collected 51 clinical samples from our facility to calculate the cutoff score. According to the age of the participants in the original CSHQ (4-10 years), validation was assessed statistically via exploratory and confirmatory factor analyses and internal consistency (verified by Cronbach's α). Multivariate analysis was conducted to identify factors affecting the CSHQ-J total score.
Results:
We received responses from 2687 participants (response rate: 85%) and analyzed 1688 participants who were the age of the original CSHQ participants. The alpha coefficients of each subscale of the CSHQ-J ranged from 0.43 to 0.68. The cutoff score was 48 (sensitivity: 0.69, specificity: 0.79). The confirmatory and exploratory factor analyses did not converge. Multivariate analysis showed that the factors that significantly influenced the CSHQ-J total score were co-sleeping, supplemental sleep, and child's age. Present illness, especially adenoids, also significantly influenced CSHQ total score.
Conclusions:
The CSHQ-J has adequate internal consistency and is useful for screening for pediatric sleep disorders. Supplemental sleep, habit of co-sleeping, and child's age should be considered when using the CSHQ-J as a screening tool for sleep problems in children.
