Functional Outcomes of Sleep Questionnaire (FOSQ)

« Back to Glossary Index

The Functional Outcomes of Sleep Questionnaire (FOSQ) was developed in 1997 as a means to measure the impact of excessive daytime sleepiness on a person’s daily ability to function. The 30 questions are divided into five subscales – activity level, vigilance, intimacy and sexual relationships, general productivity, and social outcomes. A shorter version, FOSQ-10, is also available; this shorter version contains only 10 questions.
