Daily fluctuations in adolescents' sleep predict next-day attention, sleepiness, and fatigue: an ecological momentary assessment study over 28 days.

Background: Current understanding of the associations between adolescents' daily sleep and daytime alertness and fatigue under naturalistically occurring restricted (school) and unrestricted (vacation) sleep opportunities is limited.

Methods: A convenience sample of adolescents (n = 205; 54.1% females, M ± SD = 16.

The longitudinal trajectory of depression and anxiety across the perinatal period.

The understanding of long-term depression and anxiety trajectories across the perinatal periods is lacking. This longitudinal study investigated the change trajectories of both depressive and anxiety symptoms, as well as the associations of their trajectories over five years. The study included nulliparous participants (N = 163, M = 33.

Integrating lived experience to develop a tailored sleep intervention for people living with dementia and carepartners.

Objectives: Sleep disturbances are highly prevalent and have adverse health consequences for both people living with dementia and their carepartners. Despite this, they are under-addressed caregiving settings. This study aimed to explore these sleep disturbances and co-design a multimodal sleep intervention for people living with dementia and their carepartners.

Preventing postpartum insomnia: findings from a three-arm randomized-controlled trial of cognitive behavioral therapy for insomnia, a responsive bassinet, and sleep hygiene.

Study Objectives: Insomnia symptoms are common during the perinatal period and are linked to adverse outcomes. This single-blind three-arm randomized-controlled trial examined whether two interventions targeting different mechanisms prevent postpartum insomnia.

Methods: Participants were nulliparous females 26-32 weeks gestation with Insomnia Severity Index (ISI) scores ≥ 8, recruited in Australia and randomized 1:1:1 to: (1) a responsive bassinet (RB) designed to support infant sleep and reduce maternal sleep disruption until 6 months postpartum, (2) therapist-assisted cognitive behavioral therapy for insomnia (CBT-I) delivered during pregnancy and postpartum, or (3) a sleep hygiene booklet (control; CTRL).

Daily associations between salivary cortisol and electroencephalographic-assessed sleep: a 15-day intensive longitudinal study.

Study Objectives: Current evidence suggests that cortisol levels are bi-directionally associated with sleep. However, the daily, naturalistic cortisol-sleep associations remain unclear, as current evidence is mostly cross-sectional. This study tested whether pre-sleep cortisol predicts sleep duration and quality, and whether these sleep parameters predict the following day's diurnal cortisol slope using a 15-day intensive longitudinal design with electroencephalographic measures and saliva sampling.

Effects of paternal involvement in nighttime childcare on child and maternal sleep: exploring the roles of relationship satisfaction and maternal competence about child sleep.

Study Objectives: Supportive coparenting between couples has been shown to have positive effects on the dyadic relationship, child development, and parental and child sleep. This study aimed to investigate the association between paternal involvement in nighttime childcare and child and maternal sleep, while exploring relationship satisfaction and maternal competence about child sleep as mediators.

Methods: The sample consisted of 290 mothers (mean age ± standard deviation = 34.

Multi-modal sleep intervention for community-dwelling people living with dementia and primary caregiver dyads with sleep disturbance: protocol of a single-arm feasibility trial.

Background: Disturbed sleep is common among people living with dementia and their informal caregivers, and is associated with negative health outcomes. Dyadic, multi-modal interventions targeting caregiver and care-recipient sleep have been recommended yet remain limited. This protocol details the development of a single-arm feasibility trial of a multi-modal, therapist-led, six-week intervention targeting sleep disturbance in dyads of people living with dementia and their primary caregiver.

Defining and empirically testing a two-stage build-maintain model of cognitive behavioural therapy for insomnia.

Cognitive Behavioural Therapy for Insomnia is the front-line intervention for Insomnia Disorder. However, few studies have reported data on how CBT-I implementation evolves over the course of therapy or the time course of client response. This is due, in part, to no formal framework for defining stages of CBT-I.

Assessing 'readiness' by tracking fluctuations in daily sleep duration and their effects on daily mood, motivation, and sleepiness.

Study Objectives: Consumer sleep trackers issue daily guidance on 'readiness' without clear empirical basis. We investigated how self-rated mood, motivation, and sleepiness (MMS) levels are affected by daily fluctuations in sleep duration, timing, and efficiency and overall sleep regularity. We also determined how temporally specific these associations are.

Protocol for a randomized controlled study examining the role of rapid eye movement sleep in fear-related mechanisms: rapid eye movement fragmentation and fear inhibition in adults with insomnia disorders before and after cognitive behavioral therapy for insomnia.

Insomnia confers a 2.5-to-3-fold risk of developing posttraumatic stress disorder (PTSD) after a traumatic event. The mechanism underlying this increased risk, however, remains unknown.

Tailoring cognitive behavioural therapy for insomnia across contexts, conditions, and individuals: What do we know, where do we go?

Cognitive behavioural therapy for insomnia (CBT-I) is considered the front-line treatment for insomnia. Despite the demonstrated effectiveness of CBT-I, it is necessary to consider how CBT-I may be tailored to different individuals. The purpose of the present review is to provide a summary of literature on tailoring CBT-I to different individuals and provide directions for future research.

Vulnerability to sleep-related affective disturbances? A closer look at dysfunctional beliefs and attitudes about sleep as a moderator of daily sleep-affect associations in young people.

Study Objectives: Sleep and affect are closely related. Whether modifiable cognitive factors moderate this association is unclear. This study examined whether Dysfunctional Beliefs and Attitudes about Sleep moderate the impact of sleep on next-day affect in young people.

Sleep-wake timing and chronotype in perinatal periods: longitudinal changes and associations with insomnia symptoms, sleep-related impairment, and mood from pregnancy to 2 years postpartum.

Across the perinatal transition, existing research focuses mainly on significant changes in sleep duration and quality, neglecting sleep timing. This study investigated change trajectories of sleep timing and chronotype from late pregnancy to 2 years postpartum and examined longitudinal associations of chronotype with symptoms of insomnia, daytime sleep-related impairment, and mood. Data were from a two-arm randomised controlled trial testing parent-focused wellbeing interventions.

World sleep society international sleep medicine guidelines position statement endorsement of "behavioral and psychological treatments for chronic insomnia disorder in adults: An American Academy of sleep medicine clinical practice guidelines".

This paper summarizes the position statement of the World Sleep Society (WSS) International Guidelines Committee regarding the Clinical Practice Guidelines on the Behavioral and Psychological Treatments for Chronic Insomnia Disorder in Adults prepared by a task force of the American Academy of Sleep Medicine (AASM). The practice guidelines were reviewed for their relevance and applicability to the practice of sleep medicine around the world. The WSS Work Group endorsed the AASM strong recommendation for Multicomponent Cognitive Behavioral Therapy as the treatment of choice for Insomnia Disorder and conditional endorsement for its single-therapy components (sleep restriction, stimulus control, relaxation); use of sleep hygiene education as single therapy was not endorsed due to lack of evidence for its efficacy.

Targeting emotional regulation using an Internet-delivered psychological intervention for cancer survivors: A randomized controlled trial.

Objectives: This trial assessed the efficacy of an emotion-focused, modular, Internet-delivered adaptation of the Unified Protocol (UP) in improving cancer survivors' emotion regulation strategies.

Design: A two-arm randomized controlled trial (1:1) was used to compare the efficacy of two Internet-based interventions: UP-adapted CanCope Mind (CM) and lifestyle-focused active control CanCope Lifestyle (CL).

Methods: N = 224 cancer survivors randomized to CM or CL were assessed at baseline, between-modules, at post-intervention and 3-month follow-up on emotion regulation outcomes targeted by each CM module (Module 1: beliefs about emotions; Module 2: mindfulness; Module 3: cognitive reappraisal skills, catastrophizing, refocus on planning; Module 4: experiential avoidance).

Does providing feedback and guidance on sleep perceptions using sleep wearables improve insomnia? Findings from "Novel Insomnia Treatment Experiment": a randomized controlled trial.

Study Objectives: Insomnia is a disorder diagnosed based on self-reported sleep complaints. Differences between self-reported and sensor-based sleep parameters (sleep-wake state discrepancy) are common but not well-understood in individuals with insomnia. This two-arm, parallel-group, single-blind, superiority randomized-controlled trial examined whether monitoring sleep using wearable devices and providing support for interpretation of sensor-based sleep data improved insomnia symptoms or impacted sleep-wake state discrepancy.

Does changing perceptions of sleep by incorporating sleep wearables improve insomnia? Protocol for a randomized study (the Novel Insomnia Treatment Experiment).

Study Objectives: Insomnia is common in the general population and is diagnosed based on self-reported sleep complaints. There is a frequent discrepancy between objectively recorded and self-reported sleep (sleep-wake state discrepancy), especially in individuals with insomnia. Although sleep-wake state discrepancy is well-documented in the literature, it is not well understood.

Randomized controlled trial of cognitive behavioral therapy for perinatal insomnia: postpartum outcomes.

Study Objectives: This study aimed to assess the effectiveness of cognitive behavioral therapy for insomnia (CBTI) during the postpartum period as part of a larger randomized controlled trial of CBTI on perinatal insomnia.

Methods: A total of 179 women of 18-30 gestational weeks with insomnia disorder were randomly assigned to CBTI or an active control (CTRL) therapy. Participants were assessed between 18 and 32 weeks of pregnancy at baseline, after the intervention during pregnancy, and at 8, 18, and 30 weeks postpartum.

Coping strategies predict daily emotional reactivity to stress: An ecological momentary assessment study.

Background: Emotional reactivity predicts poor health and psychopathology. Despite its theoretical importance, little research has tested whether coping predicts emotional reactivity to stressors. We analyse three studies to test this hypothesis for negative (NA) and positive affect (PA) reactivity to daily stressors.

Associations of Changes in Sleep and Emotional and Behavioral Problems From Late Childhood to Early Adolescence.

Importance: Sleep problems and psychopathology symptoms are highly comorbid and bidirectionally correlated across childhood and adolescence. Whether these associations are specific to discrete profiles of sleep problems and specific internalizing and externalizing phenomena is currently unclear.

Objective: To characterize individual changes in profiles of sleep problems and their prospective associations with psychopathology symptoms across the transition from childhood to adolescence.

Validation of the Parental Understanding and Misperceptions about BAby's Sleep Questionnaire using auto-videosomnography.

Background: Previous studies have suggested that parental cognitions about child's sleep may be an important factor underlying pediatric sleep problems. The current study aimed to (a) develop an assessment tool measuring parental understanding and misperceptions about baby's sleep (PUMBA-Q); (b) validate the questionnaire using self-report and objective sleep measures.

Methods: There were 1,420 English-speaking caregivers (68.

Measuring light regularity: sleep regularity is associated with regularity of light exposure in adolescents.

Study Objectives: Light is the main time cue for the human circadian system. Sleep and light are intrinsically linked; light exposure patterns can influence sleep patterns and sleep can influence light exposure patterns. However, metrics for quantifying light regularity are lacking, and the relationship between sleep and light regularity is underexplored.
