The Sleep Acceptance Scale (SAS): Development, psychometric properties, and applications.

Objectives: 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.

Method: We designed a six-item scale, rated on a 7-point Likert scale, to capture the nuances of sleep acceptance. Data were collected from 1,350 participants, both with and without sleep problems.

Food Consumption and Sleep Disturbances in 9-year-old Children.

 To assess the association of food consumption with sleep disturbances in 9-year-old children.  The present study is part of a larger cohort study named Predictors of Maternal and Infant Excess Body Weight (PREDI) that was conducted in the homes of the participants during the fourth study follow-up. Anthropometric assessment and demographic, socioeconomic, food consumption, and sleep data were obtained.

Personality traits and insomnia: direct and anxiety-mediated associations.

Insomnia is the one of the most prevalent sleep disorders in the adult population. Studies have shown that personality traits, particularly neuroticism, act as factors that predispose to and potentially perpetuate insomnia; however, there is still no consensus in the literature regarding these relationships considering their mechanisms. A total of 595 participants answered the Insomnia Severity Index, Revised Neuroticism-Extroversion-Openness (NEO) Five-Factor Inventory, Hospital Anxiety and Depression Scale, questions of the Diagnostic and Statistical Manual of Mental Disorders (fifth edition), and a sociodemographic questionnaire.

Cognitive and psychological factors associated with treatment response in ACT-I and CBT-I for insomnia.

Cognitive behavioural therapy for insomnia is the treatment of choice for patients with insomnia, but not all patients benefit, and novel psychological treatment approaches have emerged (e.g. acceptance and commitment therapy).

Personality and Sleep Psychopathology: Associations Between the DSM-5 Maladaptive Trait Domains and Multiple Sleep Problems in an Adult Population.

Given the lack of sufficient studies exploring the nature of sleep problems from the perspective of the alternative model of personality disorders (AMPD) proposed by the DSM-5, the present study is aimed at determining the associations between five trait domains such as negative affectivity and sleep problems (insomnia, parasomnia, hypersomnia, circadian rhythm sleep disorder, restless legs syndrome, and sleep-disordered breathing) in an adult population. Adults aged 18-65 from western Iran were invited to the study via virtual platforms (N = 928; 62% female) and responded online to the Brief Form of Personality Inventory for DSM-5 and the Holland Sleep Disorder Questionnaire to assess sleep problems. The regression analyses indicated that the AMPD trait domains could significantly predict both specific sleep problems (R ranges from 0.

Acceptance and commitment therapy versus cognitive behavioral therapy for insomnia: A randomized controlled trial.

Objective: To compare the effectiveness of an acceptance and commitment therapy (ACT)-based protocol and cognitive behavior therapy (CBT) for insomnia in adults.

Method: The participants comprised 227 adults with insomnia. They were randomized to six weekly group sessions consisting of acceptance and commitment therapy for insomnia (n = 76), cognitive behavioral therapy for insomnia (n = 76), or waitlist (WL; n = 75).

Adaptation and validation for use in Brazil of the Confusion, Hubbub, and Order Scale (CHAOS).

Background: The Confusion, Hubbub, and Order Scale (CHAOS in English Version) was originally developed in the USA by Matheny et al (Bringing order out of chaos: psychometric characteristics of the confusion, hubbub, and order scale. Journal of Applied Developmental Psychology 16(3):429-444, 1995) to measure chaos in the family environment, characterized by confusion, lack of routine, and organization.

Objective: To present evidence of content validity, internal structure validity, and validity based on relationships with external measures of an adapted version of the CHAOS into Brasilian Portuguese with adolescents sample in São Paulo - Brasil.

Psychological inflexibility as a predictor associated with insomnia.

Psychological flexibility has recently attracted the attention of researchers in the field of sleep disorders; therefore, in the study, psychological flexibility was evaluated as a predictor or factor related to the presence/severity of insomnia. We included 2218 individuals selected from the randomized-control trial for behavioural therapy for insomnia and cross-sectional studies, including 1797 individuals with insomnia and 421 controls without insomnia. All participants completed the DSM-5-based insomnia diagnosis interview, Insomnia Severity Index, Hospital Anxiety and Depression Scale, and Acceptance Action Questionnaire-II.

A systematic review with meta-analyses of the relationship between recurrent binge eating and sleep parameters.

Background: Sleep problems are known to compound the negative effects of other health issues, such as eating disorders and the associated behavior of binge eating. Previous studies suggested associations between binge eating and sleep problems, but the strength of the relationship is unknown.

Methods: We conducted a systematic review with meta-analyses examining the relationship between binge eating and sleep parameters.

A 25-Year Review of Nighttime Fears in Children: Past, Present, and Future.

Nighttime fears in children are common, interfere with daily functioning, and result in considerable disruption in the family. The aim of the present review was to examine empirical literature from the past 25 years that investigated the assessment of nighttime fears in young children and the efficacy and effectiveness of psychosocial treatments for children's nighttime fears. The last review of this literature was in 1997 and examined studies conducted in and prior to 1995 (King et al.

Brief treatment for nighttime fears and co-sleeping problems: A randomized clinical trial.

Sixty-eight 4-6 year old children who co-slept with their parents and who avoided sleeping alone due to intense nighttime fears were randomized to a brief combined parent-based intervention (CBT-based bibliotherapy plus doll) or a wait list control group. After the waiting period, the wait list participants were offered treatment. Co-sleeping patterns, sleep records, anxiety, general fears, and behavior problems were assessed with parent-report measures.
