父母物质惩罚对儿童睡眠质量的影响：主观幸福感的中介作用及友谊质量的调节作用

摘 要：为探讨父母物质惩罚与儿童睡眠质量的关系及其作用机制,采用问卷法对438名小学生进行调查。结果发现：（1）父母物质惩罚与儿童主观幸福感、睡眠质量之间呈现显著相关;（2）物质惩罚既能直接预测儿童睡眠质量,也能通过主观幸福感的中介作用预测睡眠质量;（3）友谊质量能在物质惩罚对儿童睡眠质量的中介中起到调节,对高友谊质量的儿童来说,物质惩罚对幸福感的作用不显著。研究结果揭示了作为物质型教养行为之一的物质惩罚对儿童睡眠质量的影响及其作用机制,能为提高儿童的幸福感及睡眠质量提供有效启示。     

Night waking in 6-month-old infants and maternal depressive symptoms

Relations between night waking in infants and depressive symptoms in their mothers at 6 months postpartum were examined using the data from the National Institute for Child Health and Human Development Study of Early Child Care. Although more depressive symptoms were only weakly correlated with a higher frequency of infant waking, longer wake times, and more total time awake, the rate of clinically significant depression scores was about double in mothers of chronically waking infants in comparison with mothers whose infants did not awaken during the night. The value of comparing subgroups to elucidate relations identified through correlations is discussed.     

Repetitive Thought Impairs Sleep Quality: An Experience Sampling Study

Although previous research has suggested that presleep negative cognitive activities are associated with poor sleep quality, there is little evidence regarding the association between negative thoughts and sleep in real-life settings. The present study used experience sampling and long-term sleep monitoring with actigraphy to investigate the relationships among negative repetitive thought, mood, and sleep problems. During a 1-week sampling period, 43 undergraduate students recorded their thought content and mood eight times a day at semirandom intervals. In addition to these subjective reports, participants wore actigraphs on their wrists in order to measure sleep parameters. Analyses using multilevel modeling showed that repetitive thought in the evening was significantly associated with longer sleep-onset latency, decreased sleep efficiency, and reduced total sleep time. Furthermore, impaired sleep quality was significantly associated with reduced positive affect the next morning, and decreased positive affect was indirectly associated with increased repetitive thought in the evening. These findings suggest the existence of a self-reinforcing cycle involving repetitive thought, mood, and impaired sleep quality, highlighting the importance of cognitive and emotional factors in enhancement and maintenance of good-quality sleep.     

How Do Mothers Help Their Children Sleep at Night? Night‐waking Strategy Use Among Mothers of Preschool‐aged Children

Night‐waking is common among preschool‐aged children. Little is known about night‐time parenting among parents of preschool‐aged children. To explore night‐waking strategy use in a community sample, 203 mothers (M age = 32 years, SD = 5.1; children's M age = 3.4 years, SD = 1.0) completed the Night‐waking Strategy Scale (NSS) and measures of general parenting, agreement with night‐waking strategies, and children's sleep. Children were grouped by age (2‐, 3‐, and 4‐to‐5‐year‐olds). Mothers endorsed using routines most frequently, followed by active comforting and rewards; limit‐setting and punishment were used less often. NSS punishment and routines were significantly associated with parenting (e.g. laxness was correlated with NSS routines, rs = ?.35 to .47, p < .001). Night‐waking strategy use was correlated with agreement with those strategies (e.g. active comforting was correlated with agreement with active comforting rs = .35 to .52, p < .001). Active comforting was correlated with the frequency of children's night‐waking for 2‐ and 3‐year‐olds (rs = .35 and .38, respectively, p < .01). Mothers of preschool‐aged children in the community engage in a range of parenting strategies to manage children's night‐waking. These strategies are largely consistent with general parenting and agreement with night‐waking strategy use. Copyright © 2014 John Wiley & Sons, Ltd.     

Goodness of fit between prenatal maternal sleep and infant sleep: Associations with maternal depression and attachment security

The current study prospectively examined the ways in which goodness of fit between maternal and infant sleep contributes to maternal depressive symptoms and the mother-child relationship across the first years of life. In a sample of 173 mother-child dyads, maternal prenatal sleep, infant sleep, maternal depressive symptoms, and mother-child attachment security were assessed via self-report, actigraphy, and observational measures. Results suggested that a poor fit between mothers’ prenatal sleep and infants’ sleep at 8 months (measured by sleep diary and actigraphy) was associated with maternal depressive symptoms at 15 months. Additionally, maternal depression mediated the association between the interplay of mother and infant sleep (measured by sleep diary) and mother-child attachment security at 30 months. Findings emphasize the importance of the match between mother and infant sleep on maternal wellbeing and mother-child relationships and highlight the role of mothers’ perceptions of infant sleep.     

Personality,hedonic balance and the quality and quantity of sleep in adulthood

Objective: Sufficient and good-quality sleep is important for individual functioning. This study explored associations between personality and sleep duration and sleep quality in adulthood. The mediating role of hedonic balance and the moderating roles of age and sex were also explored.

Method: A nationally representative sample of Australian adults (n = 14,065; M_age = 44.4 years; 53.1% women) completed self-report measures of personality, sleep, hedonic balance and demographic variables (e.g. health status, employment status) in late 2013.

Results: After controlling for demographic variables, we found that high neuroticism was associated with poorer sleep quality, and both long and short sleep durations (a curvilinear relationship). Small effects were also observed relating high extraversion and low openness to better sleep quality. Hedonic balance mediated all linear and non-linear associations between personality and sleep. Additional moderator analyses showed that high openness was more strongly related to poor sleep quality among men and young adults. High neuroticism was more strongly related to poor sleep quality among men.

Conclusion: Findings indicate that personality is important for sleep in adulthood and that hedonic balance features a prominent role in this association.     

Eveningness Predicts Negative Affect Following Sleep Restriction

Although considerable research has shown that sleep loss results in decreased positive affect, findings regarding change in negative affect are inconsistent. Such inconsistency may be due in part to variability in individual difference factors, such as chronotype, which is associated with both sleep and affective outcomes. Chronotype represents the tendency to be a morning- or evening-type person and is underpinned by the timing of circadian processes linked to sleep and mental health. The present study examined the predictive effect of chronotype above and beyond that of depression on affective response to sleep restriction in a sample of healthy sleeping adults (n = 73). Participants completed measures of chronotype and depression at baseline and measures of positive and negative affect before and after one night of sleep restriction (4 hours between 4 a.m. and 8 a.m.). Results indicate a large, significant decrease in positive affect following sleep restriction, but no statistically significant change in negative affect. Subsequent analyses showed that chronotype predicted affective response to sleep restriction, such that eveningness predicted a medium, significant increase in negative affect following sleep restriction, controlling for depression—however, there was no association between chronotype and change in positive affect in response to sleep restriction. These findings highlight a differential effect of sleep loss on positive and negative affect and suggest that evening chronotype may confer a distinct vulnerability for increased negative affect following sleep loss.
