Chronotype

Horne & Östberg morningness-eveningness questionnaire
This questionnaire consists of several questions about sleep and wake habits during a typical day, allowing for the determination of whether a person is a morning type, an evening type, or an intermediate type.This questionnaire is designed to assess an individual's sleep preferences and determine their chronotype. It is used in sleep research and chronobiology to understand circadian rhythms and help healthcare professionals tailor sleep interventions to meet each person's chronobiological needs.
  • Above 70: You are a morning person
  • Between 59 and 69: You are moderately a morning person
  • Between 42 and 58: You are neutral
  • Between 31 and 41: You are moderately an evening person
  • Less than 30: You are an evening person

Somnolence

The Epworth sleepiness scale
This scale assesses the tendency to fall asleep during the day in 8 relatively inactive everyday situations (such as watching television, reading, or sitting quietly after lunch).This questionnaire provides a subjective measure of excessive daytime sleepiness. It is used to help diagnose sleep disorders such as sleep apnea and narcolepsy, as well as to assess the effectiveness of treatments.

The total score ranges from 0 to 24:

  • A score > 10 indicates excessive daytime sleepiness (clinically significant).
  • A score > 15 indicates severe daytime sleepiness.
Start questionnaire
Insomnia

Insomnia severity index
It consists of seven questions covering: - Sleep quality, - Sleep satisfaction, - Difficulty falling asleep, - Frequency of nocturnal awakenings, - Perception of sleep quality, - Impact of insomnia on daytime functioning, - Distress caused by sleep problems.This questionnaire provides a subjective assessment of the severity of insomnia complaints and their impact on daily activities. It is used to help diagnose insomnia and evaluate the effectiveness of treatments.

The total score ranges from 0 to 28:

  • 0-7 = Absence of insomnia
  • 8-14 = Subclinical (mild) insomnia
  • 15-21 = Clinical (moderate) insomnia
  • 22-28 = Clinical (severe) insomnia

A reduction of at least 8 points between two measurements is considered clinically significant.

Life quality

SF-36
The SF-36 Health Survey is a multidimensional instrument used to assess an individual's perceived health in various domains. It consists of eight subscales that assess physical health, mental health, social well-being, and physical and emotional functioning.The purpose of the SF-36 Health Survey is to provide a subjective measure of an individual's perceived health. It is used in medical research and clinical trials to assess the impact of diseases and treatments on quality of life.Interpreting the results of the SF-36 Health Survey allows for understanding an individual's perception of health across different aspects of their life. It can assist clinicians in evaluating the impact of treatments on their patients' quality of life.Start questionnaire
Apnea

STOP-Bang Questionnaire
A simple, eight-item screening tool combining four “yes/no” symptom questions with four demographic/anthropometric items, designed to help clinicians rapidly identify patients at risk for obstructive sleep apnea (OSA) by assigning one point per affirmative answer (total 0-8).To provide a quick, easy-to-use method—originally in preoperative settings—to flag individuals who should undergo formal sleep testing.
  • 0-2 = Low risk
  • 3-4 = Intermediate risk (consider further evaluation)
  • ≥ 5 = High risk (strongly suggestive of moderate-severe OSA)

Global

Sleep Complaints Evaluation Scale (based on the SDS-CL-25)
Sleep Complaints Evaluation Scale (based on the SDS-CL-25) is a generic sleep disorder screening tool that allows assessment of multiple sleep disorders in a single questionnaire.To assess thirteen sleep disorders including insomnia, circadian disorders, OSA, restless legs syndrome, narcolepsy, parasomnias and impacts on daily functioning.

Each item is rated by the patient from 0 to 4.

The total score is obtained by adding the score for each item.

The total score ranges from 0 to 100.

  • A score above 5 for items 3, 4, 5, 6 indicates a risk of insomnia disorder
  • A score above 3 for items 6, 10, 11, 12, 13, 14 indicates a risk of OSAHS
  • A score above 3 for items 15, 16, 17 indicates a risk of restless legs syndrome

These thresholds are given for information only and are not validated.
