Summary
The brief infant sleep questionnaire (BISQ) effectively screens infant sleep issues, correlating well with objective measures and distinguishing clinical cases. It offers reliable data for pediatric settings.
Area of Science:
- Pediatric Sleep Medicine
- Developmental Psychology
- Clinical Assessment Tools
Background:
- Infant sleep disturbances are common and impact development.
- Screening tools are needed for early identification in clinical settings.
- Existing methods may be time-consuming or lack validation.
Purpose of the Study:
- To develop and validate the Brief Infant Sleep Questionnaire (BISQ).
- To establish BISQ as a reliable screening tool for pediatric use.
- To assess BISQ's correlation with objective sleep measures.
Main Methods:
- Two studies were conducted: Study I involved clinical and control infants (N=100) comparing BISQ to sleep diaries and actigraphy.
- Study II utilized an internet survey (N=1028) to assess BISQ's developmental and ecological validity.
- Test-retest reliability was assessed on a subsample.
Main Results:
- BISQ measures significantly correlated with actigraphy and sleep diary data.
- BISQ effectively differentiated clinical from control infant groups.
- High test-retest reliability (r >.82) was confirmed.
- Internet survey data supported developmental and sleep ecology findings.
Conclusions:
- The BISQ is a psychometrically sound and clinically useful brief infant sleep screening tool.
- Findings support its use in both clinical practice and research.
- Potential clinical cutoff scores are provided for practical application.
