饮酒在睡眠呼吸暂停低通气综合征患病率流行病学研究中的意义

了解饮酒对打鼾和睡眠呼吸暂停低通气综合征(SAHS)患病率的影响,为该病的防治提供依据。按照随机整群抽样法,对承德市双桥区部分30岁以上居民进行入户调查,共调查1168人,对部分2级及2级以上打鼾者进行整夜睡眠呼吸监测。结果显示饮酒与打鼾的关系密切;饮酒可以使不同性别人群打鼾的患病率升高;不同种类饮酒者打鼾的患病率有不同的差异。饮酒是打鼾和SAHS的独立危险因素,要防范打鼾和SAHS戒酒或减少饮酒量是非常重要的。     

手机成瘾对大学生认知失败的影响:一个有调节的中介模型

以问卷法对河南省三所高校的471名大学生进行调查,考察手机成瘾对大学生认知失败的影响,睡眠质量在手机成瘾与认知失败之间的中介作用,同时检验神经质和外倾性对该中介路径的调节作用。结果表明：（1）手机成瘾不仅能直接预测大学生的认知失败,还能通过睡眠质量的中介作用间接预测认知失败;（2）神经质对直接效应及中介效应的后半段路径起着调节作用,在直接路径中高神经质会加剧手机成瘾对认知失败的影响,在中介路径中,低神经质时,睡眠质量对认知失败影响较大;（3）外倾性对中介效应的后半段路径起着调节作用,高外倾性会缓和睡眠质量对认知失败的影响。     

Social contents in dreams: An empirical test of the Social Simulation Theory

Social Simulation Theory (SST) considers the function of dreaming to be the simulation of social events. The Sociality Bias and the Strengthening hypotheses of SST were tested. Social Content Scale (SCS) was developed to quantify social events. Additionally, we attempted to replicate a previous finding (McNamara et al., 2005, Psychological Science) of REM dreams as predisposed to aggressive, and NREM dreams to prosocial interactions.Further, we investigated the frequency and quality of interactions in late vs early REM and NREM dreams. Data consisted of wake, REM and NREM home dream reports (N = 232, 116, 116, respectively) from 15 students. Dreams overrepresented social events compared to wake reports, supporting the Sociality Bias hypothesis. However, the Strengthening Hypothesis was not supported. We weren’t able to replicate the McNamara et al. finding, and no time of night effect was found. While SST gained partial support, further research on social contents in dreams is required.     

Testing the benefits of expressive writing for workplace embitterment: a randomized control trial

Clinicians working in occupational health services often recognize features of embitterment in organizations; however, research on interventions for embitterment are scarce. The present study aimed to assess the effectiveness of an expressive writing intervention on working adults who experience workplace embitterment. Employing a randomized control trial we sought to test an expressive writing intervention for its effects on reducing embitterment, work-related rumination and sleep quality and assess whether the effect of the intervention was maintained over time by following up participants after one and three months. Findings partially supported our hypothesis as results showed that participants who completed the expressive writing intervention (N = 23) did not show significantly lower levels of embitterment, affective rumination, higher levels of detachment, either improved sleep quality, compared to participants who completed the factual writing (N = 21), when baseline values were controlled for. However, when looking at the mean scores embitterment and affective rumination levels diminished, detachment levels increased and sleep quality improved throughout the course of the intervention for both groups. Given the stability of embitterment and as findings from this study indicate embitterment diminished after a writing exercise irrespective of emotional disclosure taking place or not, further research and investigation are warranted.     

Problems in the neighbourhood: Formulating noise complaints across dispute resolution services

When people are in dispute with their neighbours, there are multiple routes to resolution, and different services have a range of remits to support it. This article explores how noise complaints are reported to dispute resolution mediation and local council environmental services in the United Kingdom. A collection of 315 recorded telephone calls were transcribed and analysed using discursive psychology, underpinned by conversation analytic methods. Analysis focused on how the same kinds of noise complaint were formulated for the remit and provision of the service called. In mediation calls, callers directly attributed the source of the noise to the agent of its production (e.g., “it's about the neighbour”). However, reference to “the neighbour” was typically omitted (at least initially) in calls to environmental health services (e.g., “I need to speak to someone about disturbance”). This comparative analysis of different settings reveals the significance of service remit for the design of complaints and the relevance of attributing cause in making a case for aid. Comparing two settings provides a propitious opportunity to demonstrate that noise is not a physically objective phenomenon or neutral category but institutionally formulated social conduct.     

不同睡眠时间参数对学前儿童执行功能的差异化影响

研究选取78名5~7岁的学前儿童为研究对象, 采用睡眠日志法测量了儿童的夜间睡眠比、总睡眠时长和周末补偿睡眠三个睡眠时间的指标, 同时采用母亲报告法收集儿童的消极情绪性, 3个月后采用美国国立卫生研究院(NIH)的一套标准化测量程序评估儿童的执行功能, 探讨三个睡眠时间参数对不同消极情绪性学前儿童执行功能的差异化影响。结果发现, 在控制了儿童的同时性语言能力之后, 夜间睡眠比能够显著预测儿童三个月之后的执行功能; 儿童的消极情绪性与周末补偿睡眠对执行功能的三个子成分存在显著的交互作用。当周末补偿睡眠较少时, 高消极情绪性儿童的执行功能显著低于低消极情绪性儿童; 当周末补偿睡眠较多时, 高消极情绪性儿童的执行功能显著高于低消极情绪性儿童, 该结果符合差别易感性模型。     

Facebook use and sleep quality: Light interacts with socially induced alertness

It has been demonstrated that the use of social networking sites late at night can lead to sleep‐related problems that extend into the next day. A common explanation is that the light emitted from screens is disrupting the users’ circadian rhythms. An alternative explanation is that the social cognition inherent in the use of social networking sites is responsible. Here, the two factors were looked at together. Participants used Facebook on iPad tablets before sleep. This was done on different nights with two lighting conditions and with two levels of content. In the ‘light’ condition, blue wavelength light was manipulated so that it was either full wavelength or blue light filtered. In the ‘alertness’ condition, the personal significance of the content was changed from personally relevant to irrelevant. A modified version of the Pittsburgh Sleep Quality Index was used to measure sleep‐related problems. No evidence was found that simply filtering blue light or simply removing relevant content improved sleep quality. However, the two factors interacted. The results suggest that the light emitted from screens can affect sleep quality under some conditions but this is behaviourally irrelevant in the context of normal Facebook usage.     

Sleep Quality and the Stress‐Buffering Role of Religious Involvement: A Mediated Moderation Analysis

Although several studies have documented an inverse association between stressful events and sleep quality, much less is known about the factors that might moderate or buffer against the adverse effects of psychosocial stress on sleep. Building on previous research, we employ national cross‐sectional survey data from the 2017 Baylor Religion Survey (n= 1,410) to test whether the association between recent stressful events and sleep quality varies according to several dimensions of religious involvement. We also formally assess whether any attenuation of the association between stressful events and sleep quality is at least partially mediated or explained by lower levels of depressive symptoms (mediated moderation). Our moderation analyses indicate that the inverse association between stressful events and sleep quality is in fact attenuated by religious cognitions (secure attachment to God and assurance of salvation), but not religious attendance or private religiousness. We also observe direct evidence of mediated moderation through depressive symptoms for both religious cognitions. Taken together, our results demonstrate that religious cognitions may buffer against stress‐related sleep disturbance by helping people avoid symptoms of depression.     

Evaluating motion detection to score sleep disturbance for children: A translational approach to developing a measurement system

Information obtained via direct observation of children's sleep disturbance throughout the night in their home can guide the assessment and treatment process, but watching live or via recorded video might be impractical in terms of time expenditures. In Experiment 1, we assessed the accuracy and reliability of a motion‐detection camera with human motor movements. In Experiment 2, we tested the system's generality by using it to obtain in‐home measures of sleep disturbance for three children with autism spectrum disorder and compared the accuracy to a continuous measurement system. We also measured scoring efficiency and assessed parents' acceptability of the camera. Results provide preliminary support for motion detection in measuring sleep disturbance, but further evaluation of motion detection to improve accuracy is warranted.     

Postoperative Cognitive Dysfunction Versus Complaints: A Discrepancy in Long-Term Findings

This review describes the discrepancy in findings between postoperative cognitive performance and postoperative cognitive complaints long time after an operation under general anesthesia. Shortly (from 6 hr to 1 week) after an operation a decline in cognitive performance is reported in most studies. However, long time (from 3 weeks to 1–2 years) after an operation this is rarely found although some patients are still reporting cognitive complaints. In general this kind of research is suffering from severe methodological problems (use of insensitive tests, lack of control groups, lack of parallel tests, different definitions of cognitive decline). However, these problems cannot totally explain the discrepancy in findings in the long term. Thus, there are patients who have persistent cognitive complaints long time after an operation, that cannot be measured with cognitive tests. More psychological factors such as fixation on short-term cognitive dysfunction, mood, coping style, and personality are possible explanations for these cognitive complaints in the long term. As a consequence, these factors should be a topic in future research elucidating the persistence of these cognitive complaints long time after an operation under general anesthesia.
