The Children's Sleep Habits Questionnaire (CSHQ) is a psychological questionnaire designed to measure sleep behaviors in children and adolescents ages 4–12. The 52-question test is filled out by the parent and the parent is asked to rate the frequency that their child has shown the qualities of the described sleep behaviors. This question test takes approximately 10 minutes to complete. The CSHQ has demonstrated good reliability and validity in measuring child sleep habits and problems.
