KSS

By April 12, 2016 2 Comments

The Karolinska Sleepiness Scale (KSS) is a 9-point Likert scale often used when conducting studies involving self-reported, subjective assessment of an individual’s level of drowsiness at the time.  The KSS Scores are defined as follows:

9. Extremely sleepy, fighting sleep
8. Sleepy, some effort to keep alert
7. Sleepy, but no difficulty remaining awake
6. Some signs of sleepiness
5. Neither alert nor sleepy
4. Rather alert
3. Alert
2. Very alert
1. Extremely alert

The KSS has an extensive body of literature linking KSS scores to actual workplace performance and objective measures of fatigue. The FAID Quantum BMM uses this scale and provides predicted KSS Scores, enabling the user to better understand the numeric output aided by the descriptions associated with each score value.

    We utilise FAID in our rostering system for a 24/7 transport business to establish base roster schedules and then in day of operations to maintain an appropriate FAID score. I am interested in how FAID Quantum works with the KSS score. Does it form part of the algorithm? Does it rely on individual inputs? Are you able to provide me with some information?
    Thankyou

      Thanks for your query. FAID Quantum incorporates two biomathematical models. The FAID Standard BMM, which produces FAID Scores and FAID Quantum BMM, which produces predicted KSS Scores. The FAID Quantum BMM uses work schedule input to predict sleep (or has option of entering actual sleep) and from this provides a predicted KSS Score. The FAID Quantum BMM uses this scale enabling the user to better understand the numeric output aided by the descriptions associated with each score value.
