WHAT THE TEST MEASURES

About This Assessment

Sleep Hygiene Index (SHI) Test - Symptoms and Signs

sleep

Sleep problems are often influenced by modifiable habits and environmental conditions. The Sleep Hygiene Index (SHI) is a brief self-report questionnaire designed to screen for behaviors and routines that may interfere with sleep onset or sleep maintenance.

The measure includes 13 items and typically takes about 3 minutes to complete. Items query common pre-sleep practices and contextual factors (e.g., routine consistency, evening stimulation, and related behavioral choices) to support clinical interviewing or research screening.

Scores from the Sleep Hygiene Index (SHI) can help identify targets for behavioral sleep education and guide discussion of practical changes to support healthier sleep practices. A web-based version is listed as psytests.org (2024).
