Assessing insomnia after stroke: a diagnostic validation of the Sleep Condition Indicator in self-reported stroke survivors.

Background: Insomnia is common after stroke and is associated with poorer recovery and greater risk of subsequent strokes. Yet, no insomnia measures have been validated in English-speaking individuals affected by stroke.

Aims: This prospective diagnostic validation study investigated the discriminatory validity and optimal diagnostic cut-off of the Sleep Condition Indicator when screening for Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5) insomnia disorder post-stroke.

The British Sleep Society position statement on Daylight Saving Time in the UK.

There is an ongoing debate in the United Kingdom and in other countries about whether twice-yearly changes into and out of Daylight Saving Time should be abolished. Opinions are divided about whether any abolition of Daylight Saving Time should result in permanent Standard Time, or year-long Daylight Saving Time. The British Sleep Society concludes from the available scientific evidence that circadian and sleep health are affected negatively by enforced changes of clock time (especially in a forward direction) and positively by the availability of natural daylight during the morning.

Experiences of and treatment preferences for insomnia in autistic adults: An Interpretative Phenomenological Analysis.

Insomnia and insomnia symptoms are frequent experiences of autistic people resulting in pronounced daytime effects and poor quality of life. This study employed an Interpretive Phenomenological Analysis approach to explore lived experiences of autistic adults with insomnia, perspectives on current available interventions and future treatment preferences. Twelve participants (aged 21-48 years old) were interviewed following screening for insomnia, using the Sleep Condition Indicator (scores ranged from 1 to 12; cut off >16).

Starting an undergraduate degree amid the COVID-19 pandemic: A mixed-method egocentric network study on student loneliness.

Students who began their undergraduate university studies in the midst of the COVID-19 pandemic (the 'COVID cohort'), may have been particularly at risk for experiencing increased loneliness. This study employed an exploratory egocentric network and mixed-methods approach to investigate the links between social networks and loneliness in the COVID cohort. Of sixty-one respondents meeting inclusion criteria for the study, fifty-eight first-year undergraduate students from the September 2020 intake at a large Scottish University provided egocentric network data via an online survey, as well as responses to three open-ended questions which were aimed at generating qualitative data about participants' experiences of starting university in the context of the COVID-19 pandemic.

Personality and insomnia: A systematic review and narrative synthesis.

The inherent nature of personality serves as a predisposing, and possible maintaining, factor of insomnia. However, methodological differences limit the ability to draw causal conclusions regarding the specific traits involved in the aetiology of the disorder. This systematic review of the relationship between insomnia and personality provides a narrative synthesis of the literature to date.

The effectiveness of the behavioural components of cognitive behavioural therapy for insomnia in older adults: A systematic review.

Insomnia is more prevalent in older adults (> 60 years) than in the general population. Cognitive behavioural therapy for insomnia is the gold-standard treatment; however, it may prove too cognitively taxing for some. This systematic review aimed to critically examine the literature exploring the effectiveness of explicitly behavioural interventions for insomnia in older adults, with secondary aims of investigating their effect on mood and daytime functioning.

Sleep-related attentional and interpretive-bias in insomnia: A systematic review and meta-analysis.

Cognitive models of insomnia highlight internal and external cognitive-biases for sleep-related "threat" in maintaining the disorder. This systematic review of the sleep-related attentional and interpretive-bias literature includes meta-analytic calculations of each construct. Searches identified N = 21 attentional-bias and N = 8 interpretive-bias studies meeting the inclusion/exclusion criteria.

Improving university students' mental health using multi-component and single-component sleep interventions: A systematic review and meta-analysis.

University is a time of significant transitions during a young adult's life, with delayed and shortened sleep and poor mental health a common occurrence. This systematic review and meta-analysis examined the effect of both multi-component and single-component sleep interventions on improving university students' sleep and mental health. Five databases (MEDLINE, PsycINFO, Embase, CINAHL and Cochrane Library) were searched for relevant literature published until April 2022.

A mixed methods expert opinion study on the optimal content and format for an occupational therapy intervention to improve sleep in schizophrenia spectrum disorders.

Introduction: People with schizophrenia spectrum disorder diagnoses commonly have poor sleep, which predicts various negative outcomes. The problems are diverse, including substantial circadian dysregulation, sleep-wake timing issues, hypersomnia (excessive sleep), and more classic insomnia.

Methods: This paper reports on a mixed methods expert opinion study based on the principles of Delphi methodology.

Adolescent perspectives of bedtime social media use: A qualitative systematic review and thematic synthesis.

Adolescence is often characterised by changes in sleep patterns, with reports that the average adolescent does not get the recommended sleep time. Recent qualitative research has identified the use of electronics at bedtime and engagement with social media platforms as barriers to gaining sufficient time and quality of sleep during adolescence. A systematic review and thematic synthesis was undertaken following the three-step thematic synthesis framework.

Prevalence of insomnia and insomnia symptoms following mild-traumatic brain injury: A systematic review and meta-analysis.

Sleep is commonly disrupted following mild traumatic brain injury (mTBI), however there is a lack of consensus in the existing literature regarding the prevalence of insomnia/insomnia symptoms after injury. The aim of this review was to conduct a systematic review and meta-analysis of insomnia and insomnia symptoms' prevalence following mTBI. Full-text articles published in English in peer-reviewed journals, including adults with a clinical or self-reported mild traumatic brain injury diagnosis, were eligible for inclusion.

A systematic review and meta-analysis of poor sleep, insomnia symptoms and stress in undergraduate students.

University students experience high prevalence of mental health problems and exacerbation of mental health difficulties, including sleep disturbances and stress during their studies. Stress and poor sleep quality and/or insomnia are interlinked outcomes for this population. The aim was to conduct a systematic review, and meta-analyses, of the relationships between sleep quality and/or insomnia with stress in students.

The natural history of insomnia: predisposing, precipitating, coping, and perpetuating factors over the early developmental course of insomnia.

While there is an extensive literature on predisposing, precipitating, coping, and perpetuating factors in those with chronic insomnia, very little work has been undertaken to evaluate these factors over the early developmental course of insomnia. The present aim was to determine whether several hypothesized factors in each domain (predisposing, precipitating, coping, and perpetuating), assessed during an episode of acute insomnia (AI), are related to its persistence or remission to normal sleep. Participants comprised n = 140 people with AI and n = 737 normal sleepers (NS) recruited from the general public.

Examining the Factor Structure, Reliability, and Validity of the Disturbing Dreams and Nightmare Severity Index (DDNSI) Consequences Sub-component.

: The Disturbing Dreams and Nightmares Severity Index (DDNSI) is commonly used when assessing the experience of nightmares. It comprises two parts examining i) chronicity and ii) nightmare consequences. The primary aim of the present study was to explore the dimensional structure of the optional and currently unvalidated nightmare consequences component using exploratory factor analysis.

Emotion dysregulation mediates the relationship between nightmares and psychotic experiences: results from a student population.

Sleep disruption is commonly associated with psychotic experiences. While sparse, the literature to date highlights nightmares and related distress as prominent risk factors for psychosis in students. We aimed to further explore the relationship between specific nightmare symptoms and psychotic experiences in university students while examining the mediating role of emotion dysregulation.

Mental health disorders and adolescent peer relationships.

Rationale: Mental health disorders often arise during adolescence, with disruptive behavior disorders and anxiety disorders among the most common. Given the salience of peer relationships during adolescence, and research suggesting that mental health disorders negatively impact social functioning, this study uses novel methodology from social network analysis to uncover the social processes linking disruptive behavior disorders and anxiety disorders with adolescent friendships. In particular, the study focuses on peer withdrawal, peer popularity, and peer homophily in relation to both disorders.

Psychopathy and chronotype disposition: the mediating role of depression.

This study examined the relationship between dark triad personality traits and chronotype disposition, whilst incorporating the mediating role of anxiety and/or depression after excluding individuals presenting insomnia and/or physiological sleep-disorder symptoms. Members of the general population (N = 453) completed online measures of dark triad personality traits, chronotype, and anxious and depressive symptoms. Psychopathy and Machiavellianism were independently related to an evening chronotype disposition.

Incidence and prevalence of post-stroke insomnia: A systematic review and meta-analysis.

Problems with sleep are reported to be common after stroke but the incidence and prevalence of insomnia and insomnia symptoms following stroke is not yet established. The aim of this review was to conduct a systematic review and meta-analysis of the incidence and prevalence of insomnia and insomnia symptoms in individuals affected by stroke. We searched seven main electronic databases to identify studies until September 25, 2018.

Dysfunctional sleep-related cognition and anxiety mediate the relationship between multidimensional perfectionism and insomnia symptoms.

Perfectionism is one of several personality traits associated with insomnia. Whilst research has examined the relationships between perfectionism and insomnia, the mediating role of dysfunctional sleep-related cognition (i.e.

Interactive 3D Visualisation of the Mammalian Circadian System.

The daily fluctuations that govern an organism's physiology and behaviour are referred to as the circadian rhythm. Dramatic changes in our internal or external environment can affect these fluctuations by causing them to shift abnormally. Chronic readjustment in circadian rhythmicity can lead to health defects that extend throughout the organism.

Anxiety and depression mediate the relationship between insomnia symptoms and the personality traits of conscientiousness and emotional stability.

This study examined the relationship between the Big Five personality traits and insomnia symptoms in the general population. Additionally, the mediating role of anxiety and depression was examined. Participants (N = 625) completed online measures of the big five personality traits and insomnia severity.
