Childhood Sleep Difficulties
Standardised Tools to Assess Childhood Sleep Difficulties
Early-childhood sleep difficulties are assessed with validated caregiver-report tools — chiefly the CSHQ, BISQ (under-3s) and SDSC — supported by a 2-week sleep diary and structured history. Actigraphy adds objective sleep–wake data, and polysomnography is reserved for suspected sleep-disordered breathing as a medical referral. Tool choice follows age band and comorbidity.
Sleep is the silent scaffold of early development — and measuring it well begins with the right standardised tools.
In short
In early childhood, sleep difficulties are assessed primarily through validated caregiver-report questionnaires combined with structured sleep history and sleep diaries. The most widely cited tools include the Children's Sleep Habits Questionnaire (CSHQ), the Brief Infant Sleep Questionnaire (BISQ) for under-3s, and the Sleep Disturbance Scale for Children (SDSC). Objective measures such as actigraphy and, where clinically indicated, polysomnography supplement report-based screening.The science, briefly
Because young children cannot self-report, early-childhood sleep assessment leans on caregiver-completed instruments with established norms. The CSHQ profiles bedtime resistance, sleep onset, night waking, parasomnias and daytime sleepiness in pre-schoolers and school-age children. The BISQ is calibrated for infants and toddlers, capturing sleep location, settling method and nocturnal waking. The SDSC distinguishes between disorders of initiating/maintaining sleep, arousal and breathing-related events. A 2-week sleep diary anchors these reports in real-time pattern data, while actigraphy offers an unobtrusive objective estimate of sleep–wake cycles. Polysomnography is reserved for suspected sleep-disordered breathing or atypical events — a medical, not therapy-first, referral. Tool selection follows age band, presenting concern and comorbidities such as ASD or ADHD, where sleep disruption is common.The Pinnacle way

What to watch
Persistent bedtime resistance, frequent night waking beyond age expectation, loud snoring or breathing pauses, and daytime sleepiness or irritability — especially where they affect learning, behaviour or family functioning.
Try this at home
Keep a simple 2-week sleep diary before any assessment — bedtimes, settling time, night wakings and wake times. It turns vague worry into clear, usable data for the clinician.

Frequently asked
Which sleep tool suits children under three?
The Brief Infant Sleep Questionnaire (BISQ) is calibrated for infants and toddlers, capturing sleep location, settling method and nocturnal waking, and is well suited to the under-3 age band.
When is polysomnography indicated in early childhood?
Polysomnography is reserved for suspected sleep-disordered breathing or atypical nocturnal events. It is a medical referral, not a therapy-first pathway, and is not used for routine behavioural sleep screening.
Why are caregiver-report tools used so heavily?
Young children cannot reliably self-report, so validated caregiver questionnaires with established norms — such as the CSHQ and SDSC — combined with sleep diaries form the backbone of early-childhood sleep assessment.
