Summary
Chronotype questionnaires help understand human adaptation to daily rhythms. This study developed a system to classify 75 questionnaires, aiding researchers in selecting the best tool for their specific chronobiology research needs.
Area of Science:
- Chronobiology
- Psychometrics
- Human Adaptation
Background:
- Chronotyping assesses individual differences in adapting to 24-hour environmental cycles.
- The number and variety of chronotype questionnaires have significantly increased over 50 years.
- Difficulty exists in selecting appropriate questionnaires for specific research questions.
Purpose of the Study:
- To develop a structured system for classifying and comparing chronotype questionnaires.
- To aid researchers in selecting optimal chronotype assessment tools.
- To provide a framework for predicting properties of new questionnaires.
Main Methods:
- A comprehensive literature search identified 75 chronotype questionnaires.
- Questionnaire properties were systematically defined and documented.
- A classification system based on defined properties was developed.
Main Results:
- 75 chronotype questionnaires were identified and analyzed.
- 60 questionnaires assessed chronotype exclusively; 15 assessed chronotype and other factors.
- A set of 20 properties was proposed for questionnaire classification.
Conclusions:
- The proposed classification system facilitates navigation of the diverse landscape of chronotype questionnaires.
- Researchers can use this system to select the most suitable instrument for their studies.
- The system aids in predicting the characteristics of novel chronotype assessment tools.

02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:29Personality Theory by Eysenck and Eysenck
Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...
