Harris E, Carciofo R. The association between eveningness and autistic traits: Mediating effects of depression and insomnia. Chronobiol Int 2023; 40:961-969. [PMID: 37334796 DOI: 10.1080/07420528.2023.2224872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/09/2023] [Accepted: 06/08/2023] [Indexed: 06/21/2023]
Abstract
There is a lack of research on the relationships between autistic traits and morningness-eveningness. The current research explored associations between autistic traits (preferences for routine, difficulties with imagination, difficulties with social skills, fixations with numbers and patterns, and difficulties with attention switching) and morningness-eveningness, including the component of Morning Affect (alertness/energy upon awakening). The potential mediation effects of depression and insomnia were also tested. 163 adults (university students and general population) completed an online survey including questionnaire measures of autistic traits, morningness-eveningness, depression, and insomnia. Positive correlations were found between most autistic trait subcomponents, depression, and insomnia. The autistic trait of difficulties in attention switching was correlated with more eveningness and with less Morning Affect, but significant correlations were not observed with any other autistic trait. Depression mediated the relationship between eveningness and difficulties in attention switching. Although insomnia alone was not a significant mediator, when combined with depression in a serial mediator model, a significant mediation effect was shown. The current results suggest that greater eveningness may be related with the autistic trait of difficulties in attention switching possibly through the mechanism of increased insomnia and elevated risk for depression. These findings may potentially inform interventions.

[PMID: 37338040 DOI: 10.1080/07420528.2023.2222814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/25/2023] [Accepted: 06/02/2023] [Indexed: 06/21/2023]
Abstract
Occupational stress and burnout are widely encountered among many healthcare professionals, including nurses and doctors, as well as among members of other professions. For example, nurses, who have disrupted circadian rhythms, are seen to have sleep problems. In addition, their personality traits are also considered to be related with burnout. This study aimed to identify nurses' circadian preference and personality traits along with their effects on sleep quality and their relationship with burnout. In this study, 211 nurses (40 male, 171 female) using the correlational model from quantitative research methods was used since the variables of morningness/eveningness, personality trait, sleep quality, and burnout were aimed to be investigated at once, without intervention, within the predictivity context of the relationship among them. When the scores obtained from the burnout scale were examined, it was observed that the emotional exhaustion and personal accomplishment subdimensions were so close to the median value and mean, while depersonalization was quite low compared to these sub-dimensions. The participants' sleep quality was seen to be at the lowest step of the poor sleep quality class. When the scores obtained from the MESSI scale are examined, it is seen that the scores obtained from the morning affect dimension are above the median value, and the highest average according to the Five-Factor Personality Traits Scale is obtained in the subdimensions of agreeableness and conscientiousness. Female gender, constantly work at night, having a high number of weekly working hours increased burnout level. Additionally Evening chronotype, poor sleep quality, neuroticism, agreeableness, extroversion and conscientiousness personality traits were found to be associated with burnout in this study. In the study, being of different chronotypes, having other personality traits, and varying sleep quality scores were seen to affect the sub-dimensions of burnout.

Chronobiol Int 2023; 40:812-823. [PMID: 37183995 DOI: 10.1080/07420528.2023.2212043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 04/16/2023] [Accepted: 05/04/2023] [Indexed: 05/16/2023]
Abstract
Morningness-eveningness refers to individual differences in the sleep-wake cycle. Research indicates that morningness-eveningness is associated with the Big Five (neuroticism, extraversion, openness to experience, agreeableness, conscientiousness) and the Big Two (alpha-stability, beta-plasticity) personality factors. However, the latter has not yet been tested within the multidimensional approach to morningness-eveningness. In the present study, we have adapted the Morningness-Eveningness-Stability-Scale improved (MESSi) to Polish (https://osf.io/rcxb5) to explore the associations between its subscales (morning affect, eveningness, distinctness) and the Big Two personality traits in a sample of 1106 participants (559 women and 547 men) aged 18 to 55 (M = 36.26, SD = 9.90). In bivariate correlations, morning affect was positively related to alpha-stability and beta-plasticity, distinctness was correlated negatively with alpha-stability and beta-plasticity, while eveningness was positively correlated only with beta-plasticity. Furthermore, the confirmatory factor analysis supported the original three-factor structure of the Polish version of MESSi, while the associations with affect and the symptoms of depression and anxiety attested to its validity. Overall, the present study provides the first evidence for the associations between MESSi subscales and the Big Two personality traits, as well as shows a good fit of the three-factor structure of MESSi in the Polish population.

Carciofo R. Morning affect or sleep inertia? Comparing the constructs and their measurement. Chronobiol Int 2023:1-15.

Abstract
The construct of Morning Affect (MA; alertness upon awakening/time required to feel fully awake) emerged from exploratory factor analysis of morningness-eveningness questionnaires, and while it has been equated with morningness-eveningness preference it has much conceptual overlap with sleep inertia (SI; the transitional state between sleep and being fully awake). The current study compared questionnaire measures of these constructs to help clarify their inter-relationships. A volunteer sample of 453 students at an English-medium university in China completed an online survey including the Sleep Inertia Questionnaire (SIQ), the Morningness-Eveningness-Stability-Scale-improved (MESSi), with subscales for MA, Eveningness, and Distinctness (amplitude of diurnal variation), and the reduced Morningness-Eveningness Questionnaire (rMEQ). Measures of depression, sleep quality, mindfulness, and personality were also included. Exploratory factor analysis of the SIQ, MESSi, and rMEQ items revealed seven factors: Cognitive, Emotional, and Physiological SI, Responses to SI (including one MA item), and Duration of SI (one SIQ item, 3/5 MA items, and one rMEQ item); Morningness-Eveningness (MESSi Eveningness items, plus 3/5 rMEQ items); Distinctness (3/5 MESSi items). These results suggest that Morning Affect may be better characterised as a general measure of sleep inertia, and may contribute to ongoing development/refinement of questionnaire measures of circadian functioning.

Abstract
Morningness is associated with well-being, better sleep quality, and more conscientiousness, while eveningness is associated with negative emotionality, poorer sleep quality, and less conscientiousness. The current study aimed to further understanding of associations with conscientiousness by assessing specific behavioural indicators of conscientiousness, morningness-eveningness, and also the Morning Affect and Distinctness (amplitude of diurnal variation) aspects of circadian functioning. A survey of Chinese university students (N = 369, aged 18-30, mean = 19.48, SD = 1.922; 108 males, 261 females), included the Morningness-Eveningness-Stability-Scale, measures of conscientiousness, mindfulness, life satisfaction, aspects of sleep, and the Behavioural Indicators of Conscientiousness (BIC) scale. Morningness and Morning Affect were positively correlated with life satisfaction, mindfulness, better sleep quality, more conscientiousness, and with BIC including Hardworking, Self-control, and Punctuality. Distinctness showed negative correlations with these variables. Negative correlations between Eveningness and conscientiousness, and the BIC subscales of Hardworking and Cleanliness were no longer significant after controlling for Morning Affect. Mediation analysis showed that the associations between Eveningness and conscientiousness/BIC were mediated by Morning Affect. These results extend previous research by showing associations between circadian functioning and specific behavioural indicators of conscientiousness, and suggest that low Morning Affect may provide a mechanism for the relationship between Eveningness and conscientiousness.

Abstract
The aim of the present study was to adapt the Morningness-Eveningness-Stability Scale improved (MESSi) to the Spanish adolescent population, testing its factor structure and construct validity. The participants were 725 adolescents (52.9% girls; M = 14.8, SD = 1.99) who completed the MESSi, the Morningness Eveningness Scale of Children (MESC), questions about sleep habits adapted from the School Sleep Habits Survey, and self-reported academic performance. The psychometric results support a three-factor model with the factors of morning affect, eveningness, and distinctness, which show good internal consistency. The pattern of correlations between MESSi and the other measures was in the expected direction. The MESC correlated positively with morning affect and negatively with eveningness, whereas distinctness was uncorrelated. Boys reported higher morningness, whereas girls reported higher distinctness. Eveningness was negatively related to academic performance. Overall, the results support the validity and reliability of the Spanish adolescent version of the MESSi.

Abstract
Morningness-Eveningness Stability Scale improved (MESSi) is an assessment tool that evaluates distinctness of daily changes as well as the person's propensity for morningness and eveningness. The aim of this study is to evaluate psychometric properties of the Turkish version of MESSi and associations of chronotypes and diurnal variations with personality, affect, sleep quality as well as validity of the scale in Turkish adolescents. The sample of this study consisted of 445 students between ages of 10-19. Participants filled in MESSi, Morningness/Eveningness Scale for Children, Composite Scale of Morningness, Personality Traits Scale (BIG-5), Positive and Negative Affect Scale (PANAS), Pittsburgh Sleep Quality Index (PSQI). Reliability analysis of the scale showed quite reliable internal consistency values. Confirmatory factor analysis (CFA) was used to test construct validity of three-factor model of MESSi. An acceptable model fit was demonstrated in CFA. There was a moderate and significant relationship between MA and DI subscale scores of MESSi. A moderate but negative correlation was found between MA and EV subscale scores of MESSi. MA and DI subscale scores of MESSi were found to be weakly correlated with conscientiousness, emotional stability, openness to experience and subscale scores of BIG-5, respectively. There was a positive correlation of positive affect subscale scores of PANAS with MA and DI subscale scores of MESSi. MA subscale scores of MESSi were found to be negatively correlated with scores of subjective sleep quality, latency, duration, disturbances, habitual sleep efficiency, daytime dysfunction, and global scores of PSQI. This study shows that Turkish version of MESSi is valid and reliable for use in adolescents. Three-factor MESSi provides an advantage over other chronotype scales in adolescence since it includes DI subscale as well as MA and EV subscales. Psychometric results were supported by other chronotype scales and clinical features such as sleep, affect, and personality.

Abstract
Eveningness, as opposed to other chronotypes, in childhood and adolescence is associated with more parental conflicts, such as regarding bed and rising times, which might adversely influence future relationships with parents, and adult attachments. The current survey of 524 Chinese university students (mean = 20.05 and range 18-36 years of age) investigated whether eveningness shows these adverse associations. Morning affect and amplitude distinctness facets of circadian functioning were also assessed. It was found that eveningness is not related to adults' perception of current parental relationships, or to adult attachment security, but low morning affect and stronger amplitude distinctness were associated with perception of more fatherly control, less regard for parents, and more attachment insecurity, and these were related to poorer wellbeing. These findings indicate that components of circadian functioning are related to the quality of adult relationships. Further research is needed to confirm these findings and establish explanatory mechanisms for these associations.

Abstract
Since a thorough review in 2011 by Spruyt, into the integral pitfalls of pediatric questionnaires in sleep, sleep researchers worldwide have further evaluated many existing tools. This systematic review aims to comprehensively evaluate and summarize the tools currently in circulation and provide recommendations for potential evolving avenues of pediatric sleep interest. 144 "tool"-studies (70 tools) have been published aiming at investigating sleep in primarily 6-18 years old per parental report. Although 27 new tools were discovered, most of the studies translated or evaluated the psychometric properties of existing tools. Some form of normative values has been established in 18 studies. More than half of the tools queried general sleep problems. Extra efforts in tool development are still needed for tools that assess children outside the 6-to-12-year-old age range, as well as for tools examining sleep-related aspects beyond sleep problems/disorders. Especially assessing the validity of tools has been pursued vis-à-vis fulfillment of psychometric criteria. While the Spruyt et al. review provided a rigorous step-by-step guide into the development and validation of such tools, a pattern of steps continue to be overlooked. As these instruments are potentially valuable in assisting in the development of a clinical diagnosis into pediatric sleep pathologies, it is required that while they are primary subjective measures, they behave as objective measures. More tools for specific populations (e.g., in terms of ages, developmental disabilities, and sleep pathologies) are still needed.
