Basic Nordic Sleep Questionnaire (BNSQ) is a brief, self-administered sleep questionnaire developed to assess sleep quality and quantity. It has been used in a variety of studies to measure sleep disturbances in general and specific populations.
The BNSQ is designed as a six-item scale, and assesses both sleep quality and quantity. Each item is scored from 0 to 3, with a total score of 0-18. A higher score indicates higher levels of sleep disturbances. It has been found to have good psychometric properties, including high internal consistency, test-retest reliability, and concurrent validity.
The BNSQ has been used in a variety of research studies and clinical settings. It has been utilized to identify sleep disturbances in healthy adults, as well as in special populations such as older adults, pregnant women, and patients with chronic medical conditions and mental health issues.
The BNSQ is a useful tool for assessing sleep disturbances in a wide variety of populations. It is relatively quick and easy to administer, and provides an objective measure of sleep disturbances. The BNSQ is a valuable addition to sleep assessment practices, and should be considered for use in research and clinical settings.
