Pediatric sleep questionnaire: Free PSQ template and scoring guide

Key Takeaways

The pediatric sleep questionnaire is a parent-report screening tool for sleep-disordered breathing and obstructive sleep apnea in children aged 2-18, developed by Chervin et al. at the University of Michigan.

A score of ≥0.33 on the 22-item SDB subscale (8+ items positive) indicates elevated risk for sleep-disordered breathing and warrants clinical follow-up or polysomnography.

The PSQ covers snoring, witnessed apneas, daytime sleepiness, inattention, hyperactivity, and bedtime resistance – domains that help clinicians identify children at risk of significant sleep disorders.

Deploying the pediatric sleep questionnaire as a digital intake form in practice management software like Pabau reduces paper handling, automatically captures parent responses linked to the child’s record, and surfaces scoring summaries within clinical notes.

Identifying sleep disorders in children early improves daytime functioning, academic performance, and long-term health outcomes. The pediatric sleep questionnaire has become a cornerstone screening tool in pediatrics, primary care, mental health, and developmental assessment settings.

What is the pediatric sleep questionnaire (PSQ)?

The pediatric sleep questionnaire is a parent-completed screening instrument developed by Ronald Chervin and colleagues at the University of Michigan. It screens for sleep-disordered breathing (SDB) and obstructive sleep apnea (OSA) in children aged 2-18 years.

Parents answer yes/no questions covering snoring, breathing disturbances, daytime sleepiness, and behavioral symptoms. The tool is quick to administer (5-10 minutes) and requires no special equipment, making it ideal for busy clinical settings.

The PSQ is not diagnostic – it is a screening tool only. A positive screen indicates elevated risk and typically warrants clinical follow-up with a sleep specialist or structured patient care assessment including sleep history and a physical examination. In some cases, polysomnography (sleep study) may be recommended to confirm the diagnosis.

What does the pediatric sleep questionnaire screen for?

The PSQ captures a broad range of sleep-related symptoms and daytime consequences:

• Snoring and breathing disturbances: Frequency of loud snoring, witnessed breathing pauses, gasping, or choking during sleep.
• Daytime sleepiness: Excessive daytime somnolence, difficulty waking, and daytime napping.
• Behavioral and cognitive symptoms: Inattention, hyperactivity, poor school performance, and behavioral problems.
• Sleep quality and night-time symptoms: Restless sleep, night wakings, bedtime resistance, and sleep-related sweating.
• Physical observations: Mouth breathing, witnessed apneas, and morning headaches.

These domains address the core manifestations of sleep-disordered breathing in children and help clinicians recognize when a child’s daytime behavior or school struggles may be rooted in undetected sleep pathology. The PSQ’s breadth means it can flag risk even in children whose parents might not initially recognize sleep as the underlying issue.

PSQ item breakdown: Key domains covered

The full PSQ contains 22 items organized into five key domains. Each item is answered yes/no by the parent or guardian.

Parents typically complete the PSQ before or during the first consultation. The straightforward yes/no format means clinicians can quickly identify symptom clusters and prioritize next steps in assessment.

How to score the pediatric sleep questionnaire

Scoring the pediatric sleep questionnaire is straightforward once you understand the subscale structure.

1. Identify the 22-item SDB subscale: The main clinical subscale consists of 22 items directly assessing sleep-disordered breathing symptoms and consequences.
2. Count positive responses: For each “yes” answer, assign 1 point. Sum the total number of positive responses (0-22).
3. Calculate the proportion: Divide the number of positive responses by 22 to get a decimal score (e.g., 8 positive ÷ 22 = 0.36).
4. Apply the cutoff: A score of ≥0.33 (8 or more items positive out of 22) indicates elevated risk for sleep-disordered breathing and warrants further evaluation.
5. Document and refer: Record the score in the patient’s clinical note and, if elevated, refer to a sleep specialist or order polysomnography depending on clinical judgment.

Important caveat: The ≥0.33 cutoff applies specifically to the 22-item SDB subscale. Do not apply this threshold to other subdomains or the total score without clinical validation.

Clinical validity: How accurate is the pediatric sleep questionnaire?

The PSQ was validated extensively by Chervin et al. in the original 2000 study and has been tested in multiple cohorts since. A separate pediatric obesity study found that PSQ scores predicted moderate-to-severe obstructive sleep apnea with 80% sensitivity and 100% specificity at a 0.65 cutoff, a different population and threshold from the general validation figures below.

• Sensitivity: The PSQ correctly identifies 81-85% of children with confirmed OSA on polysomnography.
• Specificity: The PSQ correctly identifies 87% of children without OSA, reducing false alarms in low-risk populations.
• Internal consistency (Cronbach’s alpha): Ranges from 0.66 to 0.89 across subscales.
• Test-retest reliability: Stable scores over 2-week retest intervals in stable patients.
• Criterion validity: Correlation with polysomnography findings (apnea-hypopnea index, oxygen saturation nadir) supports its use as a screening tool.

These metrics confirm the PSQ is a well-validated, evidence-based screening instrument. However, remember that a positive PSQ screen is not equivalent to an OSA diagnosis – clinical judgment and polysomnography remain the gold standard.

How to use the pediatric sleep questionnaire in clinical practice

Integration into your practice workflow ensures consistent screening and captures data linked to the patient record.

1. Distribute before the visit: Provide the PSQ to the parent or guardian at check-in or send it via digital intake forms in your practice management system. This saves time during the consultation.
2. Review parent responses: During the visit, scan the responses to identify any positive items. Pay special attention to snoring, witnessed apneas, and daytime sleepiness clusters.
3. Calculate the score: Tally the yes responses and divide by 22. If ≥0.33, flag the result as elevated risk and note it in the clinical record.
4. Conduct targeted history: Ask follow-up questions about the positive items – when did snoring start, how often do breathing pauses occur, how does the child perform at school. This enriches your clinical documentation and informs your differential diagnosis.
5. Refer or monitor: If the score is elevated and clinical suspicion is high, refer to a pediatric sleep specialist or order polysomnography. If the score is low but symptoms are concerning, consider other causes (allergies, adenotonsillar hypertrophy, asthma) and monitor at follow-up visits.

Many practices now deploy the PSQ as a digital EHR form, which automatically calculates the score and flags elevated results for the clinician – reducing manual work and improving consistency.

Pediatric sleep questionnaire licensing and access

The PSQ is University of Michigan copyrighted material, free to license for non-commercial academic and clinical use. However, commercial use – including use within proprietary practice management software – requires a paid license from MAPI Research Trust (ePROVIDE).

This applies if your practice sells or monetizes services that rely on the PSQ.

For clinicians using the PSQ in routine practice without commercial resale, no license is required. Always attribute the questionnaire to Chervin et al., University of Michigan, in your clinical notes.

Alternatives to the pediatric sleep questionnaire: Other pediatric sleep screening tools

While the PSQ is the most widely validated and cited tool, clinicians sometimes use complementary instruments depending on the clinical context.

Many clinicians use the PSQ as the initial screen and then deploy a complementary tool (such as BEARS) if the results suggest a broader sleep problem or if daytime symptoms predominate. Mental health practices often combine the PSQ with behavioral rating scales to capture the full picture of how sleep disturbance affects the child’s functioning.

Having the PSQ, BEARS, and other screening instruments available as digital intake workflows allows clinicians to adapt their assessment approach case-by-case without slowing down the practice schedule.

Implementing the pediatric sleep questionnaire in your practice

To ensure the PSQ becomes a consistent part of your screening process, integrate it into your intake workflow. Many practices find that patient portals and online intake forms increase completion rates – parents answer the PSQ before arriving, giving you time to review and act on elevated scores during the visit.

Store the PSQ score and clinical interpretation in the child’s electronic health record so it’s available for future visits and can be tracked over time. This is especially useful for monitoring children with mild SDB risk or those pending specialist evaluation.

For practices managing multiple pediatric patients, automated recall reminders can prompt follow-up with families whose child scored positive on the PSQ, so no child is missed while awaiting sleep specialist assessment.

Conclusion

The pediatric sleep questionnaire is a validated, efficient screening tool that takes parents 5-10 minutes to complete and clinicians 2-3 minutes to score.

A score of ≥0.33 on the 22-item SDB subscale indicates elevated risk and warrants further clinical evaluation or specialist referral. Remember: the PSQ is a screening tool, not a diagnostic test. Polysomnography remains the gold standard for confirming obstructive sleep apnea.

Deploying the pediatric sleep questionnaire in your practice is a small step that yields significant clinical returns. Early identification of sleep-disordered breathing prevents missed diagnoses, improves treatment outcomes, and supports better long-term health trajectories for your young patients.
