Narcolepsy and Idiopathic Hypersomnia (IH) are chronic sleep disorders that negatively impact the Health-Related Quality of Life (HRQoL) of those who are diagnosed with the disorders. As such, Narcolepsy and IH may also impact the HRQoL of those close to the patient (e.g. partners, parents).

Research on the prevalence of bedtime procrastination (BtP) is currently focused on the breadth of BtP presentations, with limited insights into the severity of BtP in terms of its frequency, duration, and dysfunctional impacts. This study aimed to explore the BtP severity and its prevalence among Chinese college students. Moreover, correlates and outcomes of BtP were also examined.

To explore the attitudes and experiences of people with chronic low back pain (LBP) on sleep, health care, and digital health.

This study examined the effects of bedroom lighting with pre-bedtime activities two hours before bedtime on sleepiness and polysomnography (PSG) sleep in community-dwelling adults with poor sleep.

To examine the relationship between insomnia symptoms and self-injurious behaviors (SIB) among adolescents and young adults, with a focus on the mediation effects of depression and anxiety on this association.

This case series examined the feasibility and preliminary effects of group-based, videoconference-delivered cognitive-behavioral therapy (CBT) combined with morning light therapy (LT) in adolescents with delayed sleep timing.

Research indicates a strong relationship between dietary inflammation and sleep; however, such research is limited among women postpartum. We studied whether prenatal and postnatal pro-inflammatory diets were associated with postpartum sleep quality and duration.

Bedtime procrastination describes going to bed later than intended, leading to insufficient sleep. Although difficulty falling asleep and pre-sleep arousal are assumed to cause bedtime procrastination, the relationship has not been directly examined. In this study, we examined whether difficulty falling asleep and pre-sleep arousal lead to bedtime procrastination.

To examine the associations between parent perceived environmental factors, nighttime sleep duration and 24-h sleep duration among an international sample of preschool-aged children.

Insomnia is highly comorbid with mental health conditions, yet graduate psychology students receive limited training in sleep and insomnia management. An online introductory sleep workshop focused on insomnia management with Cognitive Behavioral Therapy for Insomnia (CBT-I) was developed for Australian graduate psychology students to address this training gap. However, some students reported difficulties applying CBT-I knowledge to clinical practice. This study explored the barriers and facilitators to implementing CBT-I knowledge into graduate psychology students' practice post-workshop.

Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for insomnia. However, patients with objective short sleep duration may show a reduced response to CBT-I and require alternative or additional treatment.This study investigated the effect of objective and subjective short sleep duration before treatment on response to CBT-I in patients with chronic insomnia.

This study employed a multilevel autoregressive mediation model to clarify the longitudinal role of poor sleep quality in the association between mobile-phone addiction and depressive symptoms among Chinese college students.

Sleep and depression are known to be related in patients with fibromyalgia but the strength of this association is not well defined. Hence, this study aimed to investigate the association between subjective and objective sleep parameters with depression and to quantitatively summarize the results.

This study assessed the effects of cognitive therapy (CT) for depression on insomnia in women with metastatic breast cancer.

Women are less adherent to continuous positive airway pressure (CPAP) treatment than men, but the reasons remain unclear. This study explored women's unique challenges, experiences, and support needs during CPAP initiation and adherence.

Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment over medication. However, its use among Veterans in the Polytrauma/Traumatic Brain Injury System of Care (PSC) - a high-riskgroup for insomnia and medication complications - remains unclear. We describe CBT-I utilization in the PSC and identify predictors of receiving CBT-I.

Sleep-disordered breathing (SDB) is common in ischemic stroke patients and may influence recovery and long-term outcomes. This systematic review and meta-analysis aims to evaluate the impact of SDB on clinical outcomes of ischemic stroke including complications, cognitive impairment, hospitalization, recurrent stroke, and mortality.

We developed and evaluated the psychometric properties of the Sleep Acceptance Scale (SAS), a tool designed to measure sleep acceptance via cognitive and emotional responses to sleep problems.

This study aimed to develop a short form of the Korean version of the Sleep-Related Behaviors Questionnaire (SRBQ) and assess its validity and psychometric properties.

Insomnia often involves physiological hyperarousal, particularly autonomic dysregulation. Although Cognitive Behavioral Therapy for Insomnia (CBT-I) is effective, some patients do not achieve complete remission. This preliminary study evaluated whether combining CBT-I with heart rate variability (HRV) biofeedback could enhance treatment effects by improving autonomic regulation.

The PANAS is the most widely used measure to detect changes in mood following sleep loss. Although insufficient sleep is associated with enhanced negativity, negative affect items on the PANAS appear unaffected. We examined whether PANAS items were deemed relevant to sleep and subsequently developed a novel tool reflecting changes in negative and positive affect with sleep (NAP-AS).

This study aimed to determine the extent to which Cognitive Behavioral Therapy for Insomnia (CBT-I) influences participant willingness to seek treatment for behavioral health conditions. We hypothesized that, relative to sleep hygiene control, CBT-I would be associated with increased willingness to seek treatment for alcohol use, depression, anxiety, PTSD, and chronic pain. Since all participants had insomnia, we also tested CBT-I effects on willingness to seek treatment for residual or future episodes of insomnia.

Insomnia and its association with mental health problems are prevalent in young populations. While person-centered statistical methods have identified insomnia phenotypes using a wide range of variables, the potential of common screening tools like the Insomnia Severity Index (ISI) for subtyping insomnia is underexplored. This study aimed to investigate insomnia subtypes in university students using ISI items.

The present study evaluated associations among sleep health, insomnia symptoms, and loneliness across the adult lifespan.

Insomnia is common for women with breast cancer, and related to fatigue, depression, and pain. Research exploring these symptoms among breast cancer patients in medically underserved areas is lacking. This study aimed to characterize symptom severity, and examine how fatigue, depression, and pain vary based on categories of insomnia severity.

Stroke sleep disorders have negative effects on physiological function, readmission rate and mortality. However, the effects on cognitive function were inconsistent. This study aims to identify the impact of sleep disorders on cognitive functions in stroke, and the relationship between types of sleep disorders and cognitive disorders.

To examine the mediating role of depressive symptoms in the relationship between internalized homophobia and sleep quality among sexual minority men (SMM), and test whether perceived social support moderates this pathway.

The cultural and historical experiences of African American family caregivers increase their risk for poor sleep health. Limited research representation hinders the development of effective sleep interventions for their unique needs. The purpose of this study is to explore the barriers and facilitators to sleep health in African American family caregivers and describe participants' preferences and recommendations for sleep health interventions.

This study examined whether the interaction between chronotype and sleep duration moderates the relationship between smartphone usage time and problematic smartphone use (PSU) among early adolescents.
