MEQ chronotype

The morningness-eveningness questionnaire ( MEQ) is a self-assessment questionnaire developed by researchers James A. Horne and Olov Östberg in 1976. Its main purpose is to measure whether a person's circadian rhythm (biological clock) produces peak alertness in the morning, in the evening, or in between Morningness -Eveningness Questionnaire (MEQ) Assess morningness and eveningness. Questions are framed in a preferential manner, where the respondent is asked to indicate when, for example, he/she would prefer to wake up or start sleep, rather than when he/she actually does. Numerical : Multiple choice, 4-5 point scale

  2. Each instrument evaluates a different aspect of chronotype. MEQ is considered to evaluate the phase preferences of individual behavior over a 24-hour day, while MCTQ measures the phase of sleep positions for both free and work days. CSM is similar to MEQ, but is more sensitive to measure shift work. The concept of chronotype has been used to refer to phase positions or phase preferences in the literature reviewed. Most of the time this is a consequence of different interpretations: it is not.
  3. CSM consists of 9 items from the MEQ and 4 items from the Diurnal Type Scale and is regarded [by whom?] as an improved version of MEQ. It currently exists in 14 language versions [citation needed]; the most recently developed are Polish, Russian and Hindi. Others. Roberts, in 1999, designed the Lark-Owl Chronotype Indicator, LOCI

The Horne and Ostberg Morningness-Eveningness Questionnaire (MEQ) is the most frequently used to assess individual chronotype. The distribution of MEQ scores is likely to be biased by several fact, ors, such as gender, age, genetic background, latitude, and social habits. The objective of the present study was to determine the effect of different social synchronizers on the sleep/wake cycle of persons with different chronotypes. Volunteers were selected from a total of 1232 UFPR. Fragebogen zum Chronotyp (D-MEQ) Bitte lesen Sie jede Frage sorgfältig durch, bevor Sie antworten.

  3. Indicated as an option in the diagnosis of DSPD and ASPD, the Morningness-Eveningness Questionnaire (MEQ) 13 is a subjective assessment of chronotype. The MEQ includes self-report questions that ask respondents about their desired sleep-wake habits and preferred or most productive time for completing activities (e.g., exercise, cognitive challenges). Higher scores are indicative of a morning type, and lower scores are indicative of an evening type. MEQ scores have been shown to correlate.

Comparison of chronotype classification using MCTQ and MEQ

The Munich Chronotype Questionnaire (MCTQ) derives chronotype from sleep timing on work-free days and therefore represents a biological measure for the circadian clock, whereas the Morningness-Eveningness-Questionnaire (MEQ) assesses chronotype as a subjective preference for different activities at specific times of day. Chronotype changes with age, with adolescents and young adults being especially late types. We conducted a systematic literature research and identified studies that explore. The Standard Questionnaire for identifying the chronotypes (Morningness-Eveningness Questionnaire - MEQ) is constituted by 19 auto-evaluating questions for identification of the chronotype and whose global score varies from 16 to 86. Individuals with values below 42 are classified as evening type; those above 58, as morning type and those between 42 and 58, as indifferent type. This questionnaire was translated and adapted for the Portuguese language by the Multidisciplinary. Both the MEQ scores and chronotype percentages were used in the statistical evaluations. In brief, the frequency distribution of the MEQ scores was analyzed to investigate the overall distribution of chronotypes, and then the percentages of each were evaluated. To further investigate the dynamic changes in chronotype with age, the survey results were analyzed in different age groups. The mean MEQ scores and the chronotype percentages were plotted separately to visualize the age. The morningness/eveningness questionnaire (MEQ) determines daily preferences producing a score, and the Munich ChronoType Questionnaire aims to determine phase of entrainment producing a time. An.

Chronotype: a review of the advances, limits and

Chronotype refers to individual differences in sleep timing and in preferences for a given time of day (Adan et al., 2012).Morning types prefer to get up and go to bed early, while evening types get up and go to bed later (Adan et al., 2012).This aspect refers to sleep timing (when to sleep) rather than to the sleep duration itself, and it is considered a different construct (Randler, 2014) Over several decades, biologists, psychiatrists, and neurologists have developed questionnaires to help you determine your sleep chronotype. Automated Morningness-Eveningness Questionnaire (Auto-MEQ): This self-assessment questionnaire is based on a 1976 template developed by Swedish psychiatrist Olov Östberg.For its part, the Östberg Morningness-Eveningness Questionnaire builds on the work. Sleep chronotype is closely related to circadian rhythm, which controls the day-to-day sleep-wake cycle and releases melatonin in response to environmental cues such as light and temperature. However, while circadian rhythm can be trained by adhering to a strict schedule, the underlying chronotype exists on a more permanent basis The Morningness-Eveningness Questionnaire (MEQ) and Munich ChronoType Questionnaire (MCTQ) are sometimes used to estimate circadian timing. However, it remains unclear if they can reflect a change in circadian timing after a light treatment. In this study, 31 participants (25-68 years) completed both questionnaires before and after a 13-28 day morning light treatment. The dim light.

Significant negative correlations of chronotype-MEQ score with STAI state-anxiety (r = -0.40, p < 0.05), STAI trait-anxiety (r = -0.40, p < 0.05), and STAI pre-sleep state anxiety (r = -0.30, p < 0.05) were observed. Eveningness preference was associated with higher trait, state, and pre-sleep state anxiety. Conclusions: These results suggest that chronotype may be an important parameter to. In the present study, chronotypes were determined based on the scores of the Morningness-Eveningness Questionnaire-K (MEQ-K) [ 30, 31 ]; a higher score indicated a morning type and a lower score indicated an evening type

Comparing the Morningness-Eveningness Questionnaire and

Similarly, in a random sample of the Finnish population, chronotype was assessed via a shortened version of the MEQ . Dietary data were collected with the use of a validated FFQ. Greater eveningness, as demonstrated by lower morning-to-evening score, was associated with a lower intake of whole grains, rye, potatoes, and vegetables and roots, whereas intake of wine and chocolate was higher. CLOCK3111 T/C interacts with chronotype assessed by MEQ (evening type versus morning type) for obesity (body weight at baseline, kg) in severely obese subjects (P-value for the interaction <0.001) Chronotype was determined by the MEQ. The questionnaire consists of 19 items regarding preference for sleep and wake times as well as the time of day the respondent feels at peak performance. There is a designated point value for each answer choice. Once totaled, there are 5 categories or chronotypes. The highest point values correlate with a definite morning type and the lowest point values. We report on results from an Internet survey of sleeping habits in a Dutch population using the Munich Chronotype Questionnaire (MCTQ), supplemented with the Horne-Östberg Morningness-Eveningness Questionnaire (MEQ). The MCTQ was completed by 5,055 responders, of which 2,481 also completed the MEQ. MEQ score correlated well with the MCTQ assessment.

The MEQ asks about the preferred daily timing for a range of activities (e.g., physical exercise, eating) producing an arbitrary score, whereas the MCTQ asks and utilizes the actual sleep-wake times on work and work-free days to determine chronotype by the mid-point of sleep on days off Unlike the MCTQ, which derives chronotype from sleep timing on school/work‐free days, the MEQ assesses chronotype based on diurnal preferences (e.g., preferred time of day to perform physical and mental work; Horne & Östberg, 1976). With this questionnaire, chronotype is categorized as a score (range: 16-86), with high numbers corresponding to morning types (59 and above), low numbers. Chronotype was estimated through questionnaires (MEQ, rMEQ, MCTQ) and the circadian rhythm of wrist temperature. Synchrony effects were found for both wrist temperature and subjective affect, but not for behavioral performance. Morning-types showed earlier phases of circadian rhythms in temperature, reported better sleep quality, more positive affective balance, accepted more unfair offers. Along with the MEQ, other morningness-eveningness scales have been developed, including the 7-item Diurnal Type Scale (DTS) [48] and the 19-item Circadian Type Questionnaire (CTQ) [20] consisting of three scales, one measuring morningness (6-items), but criticized for weak psychometric properties [10], thus further improved to Circadian Type Inventory [18].Although the MEQ seems to be the most.

Patients' MEQ scores (β=-0.473, P=0.003) were negatively correlated to ADHD symptoms. The present results suggest a linkage between the PGV and circadian preference in adults with ADHD and an association of the circadian preference to symptom severity. This may facilitate the development of new chronobiological treatment approaches for the add-on treatment in ADHD Determination of chronotype was based on responses to the validated Italian version of the MEQ (Zani et al., 1984), a self-report questionnaire initially designed by Horne and Ostberg (1976). It includes 19 multiple-choice items that investigate preferences for sleep and activity, the mood before retirement or after awakening, and the time of day in which the respondent feels most active. The. ABSTRACT A chronotype is a designation for individual preference of times for different activities in humans. In chronobiological research, it can be measured in many ways, including subjective questionnaires. The most frequently used questionnaires for determining the chronotype are Morningness-Eveningness Questionnaire (MEQ) and Munich Chronotype Questionnaire (MCTQ)

Subjective chronotype was determined using the Morningness-Eveningness Questionnaire (MEQ) and circadian phase through analysis of salivary melatonin secretion, considering 3. pg/ml as the dim light melatonin onset (DLMO) threshold. The mean MEQ score was significantly higher in the patients with epilepsy than in the controls, and significantly, more patients had a MEQ score indicative of the. Introduction: Chronotype refers to an individual's preference in the timing of sleep and wakefulness. MEQ is having 19 multiple choice questions with four to five options against each question and with specific score for each option and the scores can vary from zero to six. After completion of MEQ test, students were grouped accordingly. Mean of the internal theory assessment marks and. MORNINGNESS-EVENINGNESS QUESTIONNAIRE Page 3 9.

Morning types (M-types) prefer to go to sleep and wake up earlier and perform better in the mornings, whereas individuals who are evening types Chronotype changes with age, with adolescents and young adults being especially late types. We conducted a systematic literature research and identified studies that explore the association between chronotype (MEQ, MCTQ) and depressive symptoms or depressive disorders. Most of the studies showed an association between a late chronotype and depressive symptomatology. However, it is still.

1976) to determine their chronotype. The MEQ con-sists of 19 questions and generates a score between 16 and 86. Scores above 58 classify individuals as morn-ing type, scores below 42 classify individuals as eve-ning type, and scores from 42 to 58 classify individuals as neither type. MEQ scores for our subjects ranged from 27 to 69. Subjects classified as neither type (n = 5; MEQ score. morningness-eveningness questionnaire (MEQ). Differences in chronotype have been observed in individuals since the 1930's beginning with the work of Freeman and Hovland. However, it wasn't until several decades later that Aschoff and Wever demonstrated that the variability observed was related to the human circadian system (Adan & Natale, 2002).

Overall, 191 subjects (115 IBD subjects and 76 healthy controls (HC)) completed the Pittsburgh Sleep Quality Index (PSQI), Morningness-Eveningness Questionnaire (MEQ), Munich ChronoType Questionnaire (MCTQ), Short Inflammatory Bowel Disease Questionnaire (SIBDQ), and a structured Food Timing Questionnaire. Later chronotype (by MEQ) was associated with a worse SIBDQ (r = -0.209; P < 0.05). SJL was increased in IBD at 1.32 h ± 1.03 vs. 1.05 h ± 0.97 in HC, P < 0.05, when adjusted for age. Results showed that MEQ scores were significantly negatively correlated with mid-sleep parameters assessed by the MCTQ, on both, work and free days, as well as with the chronotype measure MSFsc (r = -0.580 to -0.652, all p < 0.001).

Chronotype refers to the behavioral manifestation of underlying circadian rhythms of myriad physical processes. A person's chronotype is the propensity for the individual to sleep at a particular time during a 24-hour period. 'Eveningness' (delayed sleep period) and 'morningness' (advanced sleep period) are the two extremes with most individuals having some flexibility in the timing of their sleep period. However, across development there are changes in the propensity of the sleep period. Chronotype questionnaires. Each participant completed the Morningness-Eveningness Questionnaire (self-assessment version, MEQ-SA) to determine chronotype . We also collected the Munich Chronotype Questionnaire (MCTQ) to estimate habitual bedtime Results showed that MEQ scores were significantly negatively correlated with mid-sleep parameters assessed by the MCTQ, on both, work and free days, as well as with the chronotype measure MSF sc (r = -0.580 to -0.652, all p < 0.001).
