rMEQ · Morning or evening preference
Explore when you tend to feel most alert
Source · Adan A, Almirall H. Horne & Östberg morningness-eveningness questionnaire: a reduced scale. Pers Individ Dif. 1991;12(3):241–253. CareOps English translation of its existing Korean questionnaire. Wording, response choices and descriptive score ranges follow the CareOps version and have not been independently validated in English. The existing CareOps response values and total-score boundaries are retained: below 12 for evening preference and above 17 for morning preference. This describes a preference, not a sleep disorder.
