The following questions have been adapted from the Horne-Östberg Morningness-Eveningness Questionnaire (Horne JA and Östberg O. A self-assessment questionnaire to determine morningness-eveningness in human circadian rhythms. International Journal of Chronobiology, 1976: 4, 97-100).

Some stem questions and item choices have been rephrased from the original instrument to conform with spoken American English. Discrete item choices have been substituted for continuous graphic scales. Prepared by Terman M, Rifkin JB, Jacobs J, and White TM.
