Objectives: This study sought to characterize the sleep of youth athletes and investigate relationships between sleep measures and cognitive function.

Method: Youth netball athletes (n = 19, age; 16.58 ± 1.26 years), wore an Actigraph wGT3X-BT and completed a daily sleep diary over 8 weeks. Cognitive function was measured every 2 weeks using Inquisit online software. Data were analyzed using generalized estimating equations to investigate the relationship between sleep and cognitive function.

Results: Youth athletes averaged <7 hr of sleep each night. Increases in total sleep time (β= -.13, CI [-.21, -.06]) sleep efficiency (β= -.49, CI [-.87, -.11]) and sleep quality rating (β= -12.23, CI [-21.26, -3.20]) resulted in a decrease in reaction time (p < .05). Increases in sleep onset latency (β= .04, CI [.02, .06]) and wake after sleep onset (β= .03, CI [.01, .05]) resulted in an increased error count for the digit symbol substitution task (p < .05).

Conclusion: Findings show that many youth athletes obtain less than the recommended amount of sleep. This is concerning given the importance of sleep for adolescent development. Inadequate sleep in youth athletes appears to negatively affect cognitive function. Future research should investigate the impact of inadequate sleep in youth athletes on athletic and academic performance.

Objectives: Research supports cognitive behavioral therapies for nightmares (CBT-N) in adults. However, the nuances of implementation and unstandardized nomenclature for treatment components has created confusion in the field. To provide clarification, an expert consensus panel convened to review treatment manual components and to develop guidelines for the standardized implementation and terminology of CBT-N. The aims of this paper are to report on the expert panel recommendations.

Methods: A literature review was conducted for nightmare treatment manuals that have been tested in randomized clinical trials with adults. the panel of experts evaluated the content and the main controversies regarding treatment components. The panel then established recommended treatment guidelines based on the literature and clinical experience.

Results: Recommendations pertain to which patient symptom presentations are appropriate for CBT-N and considerations for implementing treatment components including session length, relaxation training, stimulus control, sleep efficiency training, sleep hygiene, nightmare exposure, nightmare rescripting, and imagery rehearsal of rescripted dreams. The panel evaluated treatment components to inform the development of a consensus CBT-N treatment manual.

Conclusions: Using a comprehensive treatment manual based on expert recommendations will not only help disseminate nightmare treatment but also advance the field by providing clarity. These recommendations are based on the status of the field and will need to be revised to incorporate developing research evidence in nightmare treatment.

Objectives: Cognitive Behavioral Therapy for Insomnia (CBT-I) is recommended as the first-line treatment for insomnia disorders, yet its clinical application rate ranges from 1% to 29%. This study evaluated medical doctors' knowledge, attitudes, and practices regarding the use of CBT-I in treatingpatients with insomnia.

Methods: A cross-sectional study was conducted from May 8 to 26, 2021. Data were collected using an anonymous structured self-administered questionnaire with 19 questions. Multivariable logistic regression analysis identified factors influencing doctors' recommendations of CBT-I.

Results: The sample included 1494 respondents.Of these, 27.2% knew the core components of CBT-I, 86.1% believed it was a first-line treatment, and 64.1% had recommended CBT-I. The analysis indicated that female respondents were less likely to recommend CBT-I (adjusted OR = 0.76, p = .045), whereas those aged 31-40 years were more likely to recommend it (adjusted OR = 2.62, p < .001). Respondents with an undergraduate degree or lower (adjusted OR = 1.36, p = .043), those knowledgeable about stimulus control (adjusted OR = 0.67, p = .01), familiar with CBT-I (adjusted OR = 0.09, p < .001), and who viewed CBT-I as a first-line treatment (adjusted OR = 0.37, p < .001) were more inclined to recommend it.

Conclusions: Medical doctors treating insomnia have positive attitudes toward CBT-I but need better knowledge. Factors influencing CBT-I recommendations include gender, age, education level, knowledge of stimulus control, familiarity with CBT-I, and viewing it as a first-line treatment. These findings highlight the need for targeted education to improve CBT-I adoption.

Background: Compared to the general population, military personnel are at increased risk for insomnia and poor psychological well-being. The present study: (1) compared categories of insomnia severity between cadets of the Swiss Armed Forces (SAF) and previously published norms and (2) investigated the associations between insomnia and psychological well-being related to perceived stress, mental toughness, dark triad traits, and organizational citizenship behavior (OCB).

Methods: A total of 216 cadets of the SAF (mean age: 20.80 years) completed self-rating questionnaires covering sociodemographic information, insomnia, perceived stress, mental toughness, dark triad, and organizational citizenship behavior. Data on insomnia sum scores and categories of historical samples (862 young adults and 533 police and emergency response service officers) were used for comparison.

Results: Cadets of the SAF reported higher insomnia sum scores and insomnia severity categories, compared to young adults and police officers. Higher scores for insomnia were associated with higher scores for stress, dark triad traits, and with lower scores for mental toughness and OCB. Categories of low, medium, and high stress moderated the association between insomnia and dark triad traits.

Conclusions: Compared to norms of the general population, cadets of the SAF reported a higher insomnia severity. Given that standardized treatment programs for insomnia, mental toughness, and above all for coping with stress are available, such interventions might be promising avenues to improve a cadet's overall sleep, psychological well-being, and behavior.

Objectives: Sleep and internalizing problems escalate during adolescence and can negatively impact long-term health. However, the directionality of this risk-relationship remains poorly understood within a developmental context. The current study aimed to determine the directionality of this relationship in adolescents with no history of psychiatric disorder and whether sex at birth played a role in this relationship.

Methods: We used data from the Adolescent Brain Cognitive Development, an ongoing multisite longitudinal US study, that covered four waves (W1:9-11 years; W2:10-12 years; W3:11-13 years; W4:12-14 years). Analyses included 3,128 youth (50.99%girls) with no past or current psychiatric disorders at W1. The Sleep Disturbance Scale for Children and the Child Behavior Checklist were used to measure sleep and internalizing problems. Cross-lagged panel models were used to evaluate the cross-lagged relationships across waves.

Results: The sleep-internalizing cross-lagged relationship was unidirectional, with medium-large effect sizes: greater total sleep problems were associated with more severe internalizing problems at later waves (W2➔W3, coefficient = 0.052, p = .021; W3➔W4, coefficient = 0.091, p < .001), with problems in initiating and maintaining sleep predicting internalizing problems early on. Girls showed greater sleep-internalizing risk than boys.

Conclusions: Sleep-internalizing relationships change across adolescence, becoming significant and more specific from early to mid-adolescence. Sleep interventions delivered in early adolescence, to girls in particular, may have a positive short and long-term impact on internalizing outcomes.

Objective: We investigated the relationship between irregular sleep-wake patterns and other aspects of sleep and mental health among adolescents.

Methods: Community-based sample of adolescents (n = 200, mean age 16.8; 61.7% female) completed baseline assessment (i.e. sleep quality, daytime sleepiness, depressive symptoms, social anhedonia, problematic alcohol use), and 7-8 consecutive days of wearing wrist actigraphy. Irregular sleep-wake patterns were assessed via two methods, both based on actigraphy, to capture day-to-day irregularity (intraindividual variability, IIV) and weekly irregularity (social jet lag, SJL). The Bayesian variability method was performed to calculate IIV in total sleep time (TST), sleep onset, and offset time. SJL was quantified as the actual difference in the sleep midpoint on school days versus non-school days.

Results: Greater IIV in TST was associated with poorer sleep quality (B = 1.66, 95% CI, 0.14, 3.31, p < .05), and greater depressive symptoms (B = 0.72, 95% CI, 0.17, 1.35, p < .05), while greater IIV in sleep offset time was associated greater depressive symptoms (B = 0.63, 95% CI, 0.03, 1.28, p < .05), and greater problematic alcohol use (B = 0.70, 95% CI, 0.12, 1.35, p < .05), all after adjusting for age, sex, family SES, alcohol drinks, and SJL. No significant association was found with sleep onset time. Greater SJL was associated with poorer sleep quality (B = 0.40, 95% CI, 0.27, 0.54, p < .001) and fewer problematic alcohol uses (B = -0.05, 95% CI, -0.09, -0.00, p < .05), when adjusting for age, sex, family SES, and alcohol drinks.

Conclusion: Our findings add to a growing body of research on irregularity in sleep-wake patterns and clinical implications.

Objective: Discrimination disrupts sleep and contributes to race-based health inequities for Black Americans, but less is known about the psychological mechanisms underlying this relation. The current work tests whether emotion invalidation, termed Social Pain Minimization (SPM), mediates discrimination's negative effects on sleep quality. We focus on the experiences of Black Americans because of racism's disproportionate effect on the health outcomes of Black individuals in the U.S.

Methods: Four studies with cross-sectional (Studies 1a-1b) and cross-lagged panel designs (Studies 2-3; N_total = 1,176) were used. Discrimination and SPM were assessed with established measures and self-reported sleep quality was assessed with three different operationalizations including the short form Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep-Related Impairment (SRI) subscale and composites of the Insomnia Severity Index (ISI).

Results: Cross-sectional (Studies 1a-1b) and longitudinal mediation analyses (Studies 2-3) indicated discrimination's negative effect on sleep quality partially operated through SPM (Study 1a, 95% CI = [-.24, -.016]); Study 1b, 95% CI = [-.22, -.03]; Study 2, 95% CI = [-.268, -.007]]; Study 3, 95% CI = [-0.043, -.002]).

Conclusion: Beyond its direct negative effect on sleep, discrimination also operates through SPM to reduce sleep quality. Emotion invalidation stemming from discrimination damages sleep.

Objectives: Sleep disorder is a growing public health concern that requires attentive assessment and treatment. However, the length of assessment tools for sleep disorders, including insomnia, hinders their use in both research and clinical settings. Brief assessment measures expedite assessment time, reducing respondent burden, and save resources, especially in resource-limited settings.

Methods: This study investigated the validity and reliability of a short three-item insomnia scale, the Insomnia Severity Index-3 (ISI-3) and established two cutoff scores in a sample of 238 healthcare providers in Oman (45.8% physicians and 54.2% nurses).

Results: The ISI-3 demonstrated good convergent and divergent validity. The receiver operator characteristic recommended two cutoff scores of > 4 (a sensitivity of 0.87.3 and a specificity of 0.96.4) and > 6 (a sensitivity of 0.96.9 and a specificity of 0.97.1).

Conclusions: The ISI-3 is a good assessment index of insomnia, especially when the utilization of the full insomnia index is unfeasible.
