Sleep Quality Scale

    The Sleep Quality Scale (SQS)

    Consisting of 28 items, the SQS evaluates six domains of sleep quality: daytime symptoms, restoration after sleep, problems initiating and maintaining sleep, difficulty waking, and sleep satisfaction. Developers hoped to create a scale that could be used as an all-inclusive assessment tool – a general, efficient measure suitable for evaluating sleep quality in a variety of patient and research populations.

    Total scores can range from 0 to 84, with higher scores demoting more acute sleep problems.
