Sleep Condition Indicator

The Sleep Condition Indicator (SCI) is a short, evidence-based questionnaire designed to screen for insomnia disorder and assess sleep quality. Developed by Professor Colin Espie and colleagues, the SCI aligns with the diagnostic criteria of the DSM-5 and is suitable for use in both clinical and research settings. It includes eight questions that explore key aspects of sleep, such as duration, quality, frequency of disturbances, and the impact on daily functioning.
