The interest in the systematic study of the circadian typology (CT) is relatively recent and has developed rapidly in the two last decades. All the existing data suggest that this individual difference affects our biological and psychological functioning, not only in health, but also in disease. In the present study, we review the current literature(More)
Morningness-eveningness preference (morning-, intermediate-, evening-type) or circadian typology is the individual difference that most clearly explains the variations in the rhythmic expression of biological or behavioral patterns. The aim of this study was to analyze gender difference in morningness-eveningness preference using the Horne and Ostberg(More)
The aim of this study was to examine sex differences in sleep-time preference by age among Italian pre-adolescents, adolescents, and adults. The final sample consisted of 8,972 participants (5,367 females and 3,605 males) from 10 to 87 yrs of age. To assess preferred sleep habits, we considered the answers to the open-ended questions of the(More)
The purpose of the present study is to explore the relationships between circadian typology and Cloninger's model of the seven dimensions of personality, taking into account the possible sex interactions. This model considers four temperament dimensions (viz., HA, harm avoidance; NS, novelty seeking; RD, reward dependence; and PS, persistence) and three(More)
We explored the relationship between personality, based on the five-factor model, and circadian preference. To this end, 503 participants (280 females, 223 males) were administered the Morningness-Eveningness Questionnaire (MEQ) and the self-report version of the Big Five Observer (BFO) to determine circadian preference and personality features,(More)
The present study analysed the efficiency of postural control after 12 h of nocturnal forced wakefulness using Romberg's test comprising 1 min of recording with eyes-open and 1 min of recording with eyes-closed, with a 1 min break between the two sessions. Our aim was to see if the decreased postural control efficiency after a sleepless night was unspecific(More)
Morningness scales have been translated into several languages, but a lack of normative data and methodological differences make cross-cultural comparisons difficult. This study examines the psychometric properties and factor structure of the Composite Scale of Morningness (CSM) in samples from five countries: France (n = 627), Italy (n = 702), Spain (n =(More)
The present study explores the relationships between functional and dysfunctional impulsivity factors, circadian typology, and sex. A sample of 850 university students (396 men) aged between 18 and 33 yrs of age completed the Dickman's Impulsivity Inventory (DII) and reduced morningness-eveningness questionnaire (rMEQ). Factorial analysis showed a(More)
BACKGROUND Rhythm disturbances are a frequent clinical manifestation of depression. In recent years a possible relationship between depression and chronotypes has emerged. Specifically eveningness has been proposed as vulnerability factor. The aim of this study was to describe sleep features of depressed patients according to chronotypes and to explore(More)
The present study aimed to compare two commercially available actigraphs, with a concurrent polysomnographic (PSG) recording. Twelve healthy volunteers (six women; age range 19-28 yrs) simultaneously wore the Basic Mini-Motionlogger and Actiwatch for seven overnight polysomnographic recordings. Comparisons of the following sleep measures were focused on:(More)
