The aim of this study was to examine sex differences in sleep‐time preference by age among Italian pre‐adolescents, adolescents, and adults. final sample consisted 8,972 participants (5,367 females 3,605 males) from 10 87 yrs age. To assess preferred sleep habits, we considered the answers open‐ended questions Morningness‐Eveningness Questionnaire (MEQ). In agreement with previous studies, found that started shift toward eveningness 13 yrs. Females reached their peak earlier (about 17 age)...

We explored the relationship between personality, based on five-factor model, and circadian preference. To this end, 503 participants (280 females, 223 males) were administered Morningness-Eveningness Questionnaire (MEQ) self-report version of Big Five Observer (BFO) to determine preference personality features, respectively. Morning types scored significantly higher than evening intermediate conscientiousness factor. Evening found be more neurotic morning types. With reference big five our...

Summary The aim of this work was to present the Sleep Beliefs Scale (SBS), a 20‐item reviewed version Hygiene Awareness by Lacks and Rotert [ Behav. Res. Ther. , 1986 28 : 104–112]. We also examined for first time influence circadian typology in sleep beliefs. Voluntary unpaid psychology students participated study ( n = 510; 182 men 328 women), from Italy Spain, aged between 18 33 (22.80 ± 4.14 years). mean score SBS 13.05 (SD 3.46; range 2–20) total sample, with distribution positive...

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 recordings. Comparisons of following sleep measures were focused on: onset latency (SOL), total time, wake after onset, efficiency. Both devices underestimated SOL in comparison PSG, but they had similar performance compared...

The current study was conducted to evaluate the psychometric properties and analyze convergent validity of Italian version Mini Sleep Questionnaire (MSQ). In addition, it aimed put forward cut-off values be used in screening protocols.The MSQ administered 1830 participants (age range 18-87 years), whom 1208 also completed Disorder years). A subgroup 187 18-71 years) randomly chosen test test-retest reliability. complete evaluation performed on MSQ. To tool, as an external criterion validate...

Study Objective:The present study aimed to analyze season of birth effects on preferred sleep-wake cycle timing as assessed by Morningness-Eveningness Questionnaire (MEQ).

The aim of the study was to put forward quantitative criteria for Consensus Sleep Diary, differentiate people with insomnia from normal sleepers.In this retrospective study, we analyzed 295 sleep diaries patients primary (43% were male, ages ranging between 17 and 76 years) collected in two clinical centers 536 sleepers (47% 15 82 years). We considered following parameters: time bed, onset latency, total time, wake after onset, efficiency, number awakenings, terminal wakefulness, subjective...

Recent contributions have reported sleep disorders as one of the health impairment outcomes workaholism. A possible factor affecting sleep-wake cycle might be intensive use smartphones. The current study aimed to explore role smartphone in relationship between workaholism and cycle. Two serial multiple mediation models were tested on a sample 418 employees, who filled self-report questionnaires measuring workaholism, smartphones, quality daytime sleepiness, using conditional process analysis...

The main goal of the present study was to examine effects transition into and out daylight saving time (DST) on quality sleep/wake cycle, assessed through actigraphy. To this end, 14 healthy university students (mean age: 26.86 ± 3.25 yrs) wore an actigraph for 7 d before after DST fall 2009 spring 2010, respectively. following parameters have been compared transition, separately autumn changes: bedtime (BT), get-up (GUT), in bed (TIB), sleep onset latency (SOL), fragmentation index (FI),...

Abstract The cognitive functioning varies during the day and it can be modulated by time in which individuals reach their arousal peak day. Morning-types should have morning while evening-types evening, reflecting synchrony effect. aim was to investigate time-of-day effects on long-term memory with a network-like structure, using semantic classification number-matching tasks. Evening- morning-types performed two tasks three times of day: morning, afternoon evening. In task, effect found did...

The aim of the present study was to investigate, for first time, relationship between circadian preference and mood seasonality in adolescents. To this end, 1539 participants (881 female; 658 male) completed Morningness–Eveningness Questionnaire Children Adolescents Seasonal Pattern Assessment determine seasonality, respectively. Evening types achieved significantly higher scores than intermediate morning types, as intermediates did types. Agreeing with previous studies on young adults...

The current study was conducted to provide normative data on actigraphic dichotomy index (I < O) (the percentage of in bed activity counts that are less than the median out counts) healthy population and assess whether I O could be an effective discriminating circadian motor cancer patients from controls. In this retrospective study, we recovered 408 records two databases: controls (n = 182; 79 males; mean age 38.7 ± 12.6) with metastatic colorectal 226; 149 58.4 11.4). Beside usual sleep...

The present study aimed to investigate the relationship between physical self-efficacy and body mass index in a large sample of schoolchildren. Perceived Physical Ability Scale for Children was administered 1560 children (50.4% boys; 8–12 years) from three different countries. Weight height were also recorded obtain index. In agreement with literature, boys reported greater perceived than girls. Moreover, number who are obese is double that girls, while underweight half found linear...

The aim of the present study was to explore relationship between season birth and sleep-timing preferences in adolescence. To this end, Morningness-Eveningness Questionnaire for Children Adolescents (MEQ-CA) administered 1912 adolescents (1058 females 854 males), ranging age 10 17 yrs. assess preferred sleep habits, authors considered answers open-ended questions MEQ-CA (items 1 2), regarding arising time going bed time.
