Youth Self Rating Insomnia Scale

Instrument Name: Youth Self Rating Insomnia Scale

Abbreviation: YSIS

Points for Consideration:

None

Description of Tool:

The Youth Self Rating Insomnia Scale (YSIS) is an 8-item PRO developed to measure insomnia severity for adolescents. The YSIS consists of questions that ask about insomnia symptoms and waking symptoms or daytime consequences. Respondents are asked to rate each question on a 5-level scale ranging from 1 to 5 with varying response categories across items including "Very good" to "Very poor" (sleep quality), "Very good" to "Very poor" (sleep satisfaction) and "Never", "Rarely (< 1 time/week),""Sometimes (1-2 times/week)", "Often (3-5 times/week" to "Always every day (6-7 times/week" . Higher scores indicate greater insomnia severity within the past month.

Other Related Tools (if applicable):

The YSIS was developed based on the Sleep Habits Survey, Child Sleep Habits Questionnaire, Pediatric Sleep Questionnaire, Insomnia Severity Index, Athens Insomnia Scale and Pittsburgh Sleep Quality Index
