Hi,

Thanks for this great question. A short sleep questionnaire would be useful in primary care settings.

One approach would be to use a subset of questions from an established and validated questionnaire. For example:

You could choose questions that focused on your specific research interests / hypotheses. If it were me, the five questions would concern difficulty falling asleep, sleep disturbance (all cause), amount of sleep, daytime sleepiness, and overall sleep quality.

Hope that helps; best of luck!
