越轨同伴交往与青少年睡眠问题的交叉滞后分析

本研究采用交叉滞后设计探讨越轨同伴交往与青少年睡眠问题之间的双向关系。通过越轨同伴交往问卷与匹兹堡睡眠质量指数（PSQI）对广东省某地区887名青少年（43.90%男生; M = 15.55）进行为期一学年的追踪研究。在控制了性别、年龄后,结果发现:（1）学年初始的睡眠问题可以显著正向预测青少年学年末的越轨同伴交往（b2 = 0.12, SE = .05, p < .05）,即青少年在学年初始睡眠问题越多,学年末则表现出更多的越轨同伴交往;（2）研究并未发现学年初始的青少年越轨同伴交往可以显著预测其学年末的睡眠问题（b1 = –0.07, SE = .06, p > .05）。因此,本研究的结果支持了睡眠问题对青少年越轨同伴交往的单向预测作用,即睡眠问题可能是增加青少年越轨同伴交往的重要风险因素之一。

黎明模拟光照对晨起睡眠惰性的影响

本研究采用单因素被试内设计对清晨唤醒后睡眠惰性对个体主观情绪、警觉性和认知加工的影响，以及利用动态黎明模拟光照能否对睡眠惰性产生有效的对抗作用进行了考察。结果发现：（1）被试的积极情绪、主观警觉性在刚唤醒时显著低于基线水平，之后随时间推移逐渐提升。（2）被试醒后立即进行测试的认知加工成绩最差，随后逐渐提高，且主要表现在加工速度的回升上。（3）黎明模拟光照对被试醒后在积极情绪、主观警觉性、持续性注意和抑制功能的缓解上产生了明显的促进作用。这表明睡眠惰性会对个体的主客观活动产生显著的负性影响，而使用黎明模拟光照可在一定程度上对抗睡眠惰性带来的负性影响。     

原发性失眠对睡眠依赖性记忆巩固的影响及机制

现代社会的失眠问题异常突出,其对睡眠依赖性记忆巩固（SDC）的影响日益引起重视。目前,原发性失眠（PI）对陈述性及程序性记忆SDC的影响存在分歧。梳理以往研究发现,系统巩固假说和突触稳态假说支持睡眠结构紊乱及脑结构异常可能是PI患者SDC损伤的潜在脑机制。未来研究可考虑同步采集行为、脑电和脑成像数据,深入探究PI影响SDC的脑机制,并验证上述假说;还可尝试通过经颅电/磁刺激和目标记忆重激活等无创性干预措施改善PI患者的SDC效应。

Changes in Subjective-Objective Sleep Discrepancy Following Inpatient Cognitive Behavior Therapy for Insomnia

Discrepancy between objective and subjective sleep parameters is a frequent symptom in persons suffering from insomnia. Since it has an impairing effect on daytime well-being and neglects possible positive objective improvements, it would be useful if it was treated. Apart from hypnotics, cognitive behavior therapy (CBT-I) is the therapy of choice for chronic forms of insomnia. However, there is limited information about whether CBT-I can also improve subjective-objective sleep discrepancy. We investigated a large sample of patients showing chronic forms of insomnia regarding their subjective-objective sleep discrepancy pre and post CBT-I. Objective sleep data were obtained from 3 nights (2 baseline nights and 1 night after therapy) using polysomnography in our sleep laboratory. All 92 patients participated in a 14-day inpatient program with CBT-I including psychoeducation about subjective-objective sleep discrepancy. Repeated measures analyses showed an improvement in subjective-objective sleep discrepancy parameters after CBT-I. Those parameters were also correlated with perceived quality of sleep. We conclude that CBT-I is a useful tool to improve subjective-objective sleep discrepancy in patients showing chronic forms of insomnia.     

Repetitive Thought and Self-Reported Sleep Disturbance

Repetitive thought has been focused upon as a transdiagnostic risk factor for depression, anxiety, and poor physical health. Among the forms of repetitive thought, rumination and worry are considered to play important roles in the onset and maintenance of insomnia. However, there have been few attempts to clarify the similarities, differences, and interaction between the functions of rumination and worry in sleep problems. Furthermore, no study has investigated the prospective relationships between these two forms of repetitive thought and sleep disturbance. In the present study, we examined the prospective associations between repetitive thought and subjective sleep quality, measured by a self-report questionnaire. A total of 208 undergraduates participated in a 2-wave longitudinal survey with an interval of 3 weeks between assessments. Hierarchical multiple regression analyses showed that baseline rumination predicted reduction in the follow-up assessment of subjective sleep quality, controlling for levels of depressive and anxious symptoms. This main effect of rumination was qualified by the levels of worry; for individuals with higher levels of worry, rumination was associated with greater reduction in subjective sleep quality. These results suggest that both rumination and worry have unique associations with sleep and that their interaction is especially important in sleep problems.

Melatonin and Sleep Qualities in Healthy Adults: Pharmacological and Expectancy Effects

The impact of expectancy on melatonin's effects on sleep qualities was investigated. Both the pharmacological dose of 6 mg of melatonin and the expectation of receiving melatonin were predicted to improve subjective ratings of sleep qualities. The balanced placebo design varied 2 factors within-subjects: actual treatment and expected treatment. Adults (N = 53; 21 men and 32 women) between the ages of 26 and 71 years were administered either 6 mg of melatonin or a placebo for 8 nights. An instructional manipulation directed participants' expectations. Participants rated their nightly sleep experiences. Results revealed that feelings upon awakening differed between genders and that expecting melatonin increased ratings of sleep continuity. Most important, high ratings of “grogginess/tiredness” were associated with receiving melatonin, regardless of expectancy, as well as with receiving placebo when melatonin was expected. Overall, the findings underscore the need to consider expectancy and gender differences in research on melatonin and sleep experiences.     

Sleep disturbances in treatment‐seeking OCD‐patients: Changes after concentrated exposure treatment

Research indicates that patients with Obsessive Compulsive Disorder (OCD) frequently suffer from comorbid sleep difficulties, and that these difficulties often are not clinically recognized and diagnosed. There has been limited research investigating if comorbid sleep difficulties impair treatment outcome for OCD and if the sleep difficulties change following OCD‐treatment. Thirty‐six patients with obsessive compulsive disorder underwent concentrated exposure treatment delivered in a group over four consecutive days and were assessed with measures of OCD, depressive symptoms and sleep disturbance at three different time points (pre, post and 6 months follow‐up). The sample was characterized by a high degree of comorbidity with other psychiatric disorders. At pre‐treatment nearly 70% of the patients reported sleep difficulties indicative of primary insomnia. The results showed that patients had large reductions of OCD‐symptoms as well as significant improvements in sleep disturbance assessed after treatment, and that these improvements were maintained at follow‐up. Sleep disturbance did not impair treatment outcome, on the contrary patients with higher degree of sleep disturbance at pre‐treatment had better outcome on OCD‐symptoms after treatment. The results indicated that the majority of the OCD sample suffered from sleep disturbances and that these sleep disturbances were significantly reduced following adequate treatment of OCD without specific sleep interventions. However, a proportion of the patients suffered from residual symptoms of insomnia after treatment.     

Insomnia: Neurophysiological and NeuropsychologicalApproaches

Insomnia is a symptom, a syndrome and a comorbid disorder. Its diagnosis relies on subjective reports from the afflicted individual and is defined as difficulties in initiating sleep, maintaining sleep, waking up too early or non-restorative sleep. However, insomnia and especially, primary insomnia, has received much attention in insomnia research with the use of objective measures. Insomnia, its peculiarities, most frequent subtypes and two most prominent models will first be briefly introduced. Then, insomnia will be reviewed according to results obtained with the use of neurophysiological measures as basic/traditional as polysomnography to more sophisticated ones such as power spectral analysis, neuroimaging, cyclic alternating patterns and event-related potentials. In addition, a review of the discrepancies between subjective and objective reports of cognitive alterations through neuropsychological testing is offered. The need to combine measures is then highlighted in conclusion.     

Cognitive-behavioural Analysis and 1 reatment ot Insomnia

Abstract

Insomnia is a condition characterized by subjective complaints of insufficient sleep and poor daytime functioning. Objective measures of sleep and daytime functioning, however, seldom show evidence of a similar degree of dysfunction. Most insomniacs, for example, do not suffer from sleep deprivation or daytime sleepiness. This discrepancy between subjective and objective measures of sleep and daytime functioning suggests that cognitive factors may play a central role in persistent insomnia. In particular, it is argued that fears about insufficient sleep and its adverse daytime consequences tend to interfere with sleep, thereby causing a vicious cycle which serves to maintain the insomnia. It is also argued that perfectionist standards and other dysfunctional beliefs may predispose people to these kinds of fears. Finally, existing models for cognitive-behavioural treatment of insomnia are criticized for being almost exclusively focused on the night-time aspects of insomnia. If insomnia is maintained by various kinds of vicious cycles involving fears, beliefs, and standards with regard to daytime functioning, these daytime aspects of insomnia should receive more attention in cognitive-behavioural treatment.     

Sleep in Women: A Review

Sleep complaints are common in women, and women are more likely to suffer from insomnia than men. Multiple factors across a woman's lifespan, including hormonal changes, age‐related physiological changes, psychosocial factors, the presence of sleep disorders, and physical and mental health conditions, can contribute to complaints of poor sleep in women. This article reviews the literature on the characteristics of, and contributing factors to, subjectively and objectively measured sleep during the menstrual cycle, pregnancy, and post‐partum period, as well as the menopausal transition and postmenopause. Evidence from both subjective and objective measurements supports the presence of chronic sleep fragmentation associated with pregnancy, acute sleep deprivation during labour and the immediate post‐partum periods, as well as disrupted sleep during the first few months after childbirth. While there is evidence for menstrual cycle and menopause related sleep disturbance based on women's self report, findings from objectively measured sleep have been mixed. Observational and intervention studies on the relationship between sleep and women's psychological well‐being suggest that underlying causes of sleep disturbance across a woman's lifespan are often multi‐factorial. Comprehensive assessments and targeted interventions are needed in managing sleep problems in women. Cognitive behavioural interventions have been shown to reduce sleep complaints during the perinatal and menopausal periods, and improvements in sleep are likely to lead to improvements in women's overall well‐being.     

Subjective Sleep Disturbances in Sexual Assault Survivors: Associations With Trauma and Posttraumatic Stress Disorder Symptom Severity

Prior work implicates sleep disturbance in the development and maintenance of posttraumatic stress disorder (PTSD). However, the majority of this literature has focused on combat veteran men, and limited work has examined links between sleep disturbance and PTSD symptoms in sexual assault survivors. This is a notable gap in the literature, as sexual trauma is disproportionately likely to result in PTSD and is more common in women. We sought to examine the relations between subjective sleep disturbance, sexual assault severity, and PTSD symptoms in a sample of sexual assault survivors with PTSD (PTSD+), without PTSD (PTSD-), and healthy controls. The sample (N = 60) completed the Insomnia Severity Index and prospectively monitored their sleep for 1 week using the Consensus Sleep Diary. The sexual assault survivors also completed the Sexual Experiences Survey and PTSD Checklist-5. Results of group comparisons found that the PTSD+ group reported significantly higher insomnia symptoms, longer sleep onset latency, more nocturnal awakenings, and lower sleep quality compared to the healthy control group and higher insomnia symptoms compared to the PTSD- group. Results of regression analyses in the sexual assault survivors found that insomnia symptoms and number of nocturnal awakenings were significantly associated with higher PTSD symptoms, and sexual assault severity was significantly associated with higher insomnia symptoms, longer sleep onset latency, and lower sleep quality. These findings highlight specific features of sleep disturbance that are linked to trauma and PTSD symptom severity among sexual assault survivors.
