Psychometric Properties of Questionnaires for Assessing Chronotype

Abstract

suring chronotype is even greater, since the self-report instruments are most common tools for measuring chronotype. Though objective measurement of chronotypes (i.e., actigraphy, polysomnography) may also be available, these objective tools are not suitable for measuring long-term day-today variations of activity-rest-sleep rhythm [4]. Furthermore, objectively assessed activity cycle may not represent chrontypes correctly, since real life activity can be influenced by various social and occupational pressures besides chronotypes. The aim of the current review is to review several commonly used self-report questionnaires that assess chronotype. In order to evaluate psychometric properties of the questionnaires, reliability and validity of questionnaires are discussed. In the current review, we concentrate on the more widely used instruments for assessing circadian rhythm. The questionnaires include the Morningness-Eveningness Questionnaire (MEQ) [5], the reduced MEQ (rMEQ) [6], the Composite Scale of Morningness (CSM) [7], the Preferences Scale (PS) [8], Munich ChronoType Questionnaire

Sleep and fatigue in occupational health psychology research.

“…One approach to examining circadian mismatches is assessing chronotype, or individual differences in worker sleep/wake cycle preferences that may conflict with the timing of work demands. Early chronotypes (morning types) sleep/awaken early and are most alert in the morning, whereas late chronotypes (evening types) sleep/awaken late and are most alert in the afternoon or evening (Kim & Kim, 2020). Most researchers rely on self-report instruments to assess chronotypes in field research, as objective approaches involve invasive physiological measures of core body temperature or melatonin levels (Baron & Reid, 2014).…”

Fortunately, validated self-report questionnaires are also available, such as the Morningness-Eveningness Questionnaire and its reduced version (the five-item rMEQ amenable to field research), Composite Scale of Morningness, Preference Scale, Munich Chronotype Questionnaire, and the Morningness-Eveningness-Stability-Scale (for a review, see Kim & Kim, 2020).…”

“…9 Various questionnaires have been used to determine chronotype, with individuals broadly classified as the morning, neither or evening types. 12 More recently, midsleep on free days with a sleep correction (MSFscn) has been used to predict chronotype, enabling objective assessment. 13,14 There is a growing body of literature on the influence of an athlete's chronotype on athletic performance.…”
