Chloe Instrument Library

Last updated: March 28, 2026

Chloe has a library of validated measures used in research for sleep, mood, well being, and other indications.

Validated measures are surveys and questionnaires that have been tested to ensure production of reliable, accurate results.

Good to Know: It is your responsibility to license any measures you use as needed and follow the digital distribution requirements of the publisher. Some publishers and IRBs require reviewing the digital version of the measure before approving its use. 

Licensing costs and fees are NOT included in a Chloe subscription.

These are already built, and can be imported into your study for use.

Pro-Tip: When selecting your measures, consider what populations they have been validated with, if they can be self administered, and if shorter validated versions of the same measure are available.
