A cross-sectional study of the association between physical activity and depressive symptoms among adolescents in southwest China stratified by parental absence: the mediating role of insomnia and the moderating role of resilience.

OBJECTIVES: This study explored the mechanisms by which physical activity was associated with depressive symptoms in multi-ethnic (Han, Yi and Tibetan) adolescents in southwest China. The mediating role of insomnia in the association of physical activity with depressive symptoms, the moderating role of resilience in this mediation model and the moderating role of parental absence in the moderated mediation model were also examined. DESIGN: A cross-sectional survey. SETTING: In southwest China (Sichuan Province and Tibet Autonomous Region). PARTICIPANTS: 3195 adolescents from a school-based survey conducted between April and October 2020. METHODS: There were 3143 valid samples in this study (47.2% males with mean age=12.88±1.68 years). Structural equation models were developed to estimate the direct and mediating effect, and the moderating effect. Multigroup comparison was performed to examine the differences and similarities of the moderated mediation model across three parental absence subgroups: (1) both parents present, (2) one parent absent and (3) both parents absent. RESULTS: As hypothesised, physical activity was significantly and positively associated with the reduction of depressive symptoms in adolescents. Insomnia partially mediated the effect of physical activity on depressive symptoms. In addition, resilience moderated the direct and indirect effects of physical activity (through insomnia) on depressive symptoms. Finally, the multigroup comparison indicated the moderating effect of parental absence on the moderated mediation model. CONCLUSIONS: Physical activity was associated with alleviating insomnia symptoms among adolescents, thus correlating with the improvement of their depressive symptoms. Resilience was associated with enhancing the beneficial effects of physical activity, further improving depressive symptoms among adolescents, especially those with both absent parents. It is evident that physical activity interventions should be further incorporated into public health programmes to foster the physical and mental health of left-behind adolescents in southwest China.

Altered emotion perception in insomnia, anxiety, depression, mania, psychotic experiences and schizotypal symptoms: a dataset.

This data resource provides evidence concerning the prevalence of perceptual alterations of emotional faces amongst individuals experiencing symptoms of insomnia, anxiety, depression, mania, psychotic experiences, and schizotypal tendencies. More specifically, we explored the categorisation accuracy (whether the displayed emotion was correctly identified), misperception (which emotion an incorrect judgment was perceived to be), intensity (extent of the emotion signal strength) and emotional valence (the extent and direction of perceived affect) of six facial expressions of emotion from the Karolinska Directed Emotional Faces database. Complete data from N = 572 respondents are included. The dataset is available to other researchers and is provided on Figshare. Information concerning the data records, usage notes, code availability and technical validation are presented. Finally, we present demographic and correlational data concerning psychiatric symptoms and alterations in the perception of emotional faces.

Altered cingulate gyrus subregions functional connectivity in chronic insomnia disorder with anxiety.

BACKGROUND: Chronic insomnia disorder (CID) is commonly associated with mood disorders. The cingulate gyrus (CG) plays a critical role in the pathophysiology of CID and anxiety. However, the specific characteristics of altered brain networks in the CG in CID with anxiety remain unclear. This study aimed to investigate the characteristics of CG functional connectivity (FC) in CID with and without anxiety. METHODS: Resting-state functional magnetic resonance imaging was conducted on 92 CID and 36 healthy controls (HC). CID was divided into CID with anxiety (CID-A, N = 37) and CID without anxiety (CID-NA, N = 55) groups based on anxiety scores. Using the Human Brainnetome Atlas, the subregion CG FC network was constructed. RESULTS: Compared with HC, CID showed significantly decreased CG FC with the precuneus, middle frontal gyrus (MFG), and hippocampus, while showing significantly increased CG FC with the middle temporal gyrus (MTG)/superior temporal gyrus (STG). In contrast, CID-A showed significantly decreased CG FC with the salience network (insular, putamen) and default mode network (MTG/STG and inferior parietal lobule), while showing significantly increased CG FC with the thalamus and MFG compared to CID-NA. Further, CID-A and CID-NA could be classified with 84.21 % accuracy by using the CG FCs as features. Among these features, the CG FC with MFG, thalamus, and putamen had the highest contribution weights. CONCLUSION: This study revealed specific changes in the brain network of the CG subregion in CID-A. Understanding these CG FC alterations can help identify potential biomarkers specific to CID-A, which may be valuable for early detection and differentiation from other CID subtypes.

Sleep disorder syndromes of post-acute sequelae of SARS-CoV-2 (PASC) / Long Covid.

INTRODUCTION: COVID-19 infection has resulted in a high prevalence of a post-infectious syndrome, known as post-acute sequelae of SARS-CoV-2 (PASC) or "Long COVID". PASC is a heterogeneous disease with a high prevalence of sleep disturbances, varying from an insomnia disorder to excessive daytime sleepiness. METHODS: Patients seen in the Covid Survivorship Program at the Beth Israel Deaconess Medical Center Boston, USA, were screened for sleep disorders as part of a comprehensive multi-system evaluation. Those who screened positive were referred for a comprehensive sleep evaluation in a dedicated COVID-19-Sleep clinic, followed by diagnostic sleep testing and treatment. This report summarizes patients who completed an American Academy of Sleep Medicine (AASM) accredited facility-based diagnostic evaluation. International Classification of Sleep Disorders 3rd Edition-Revised criteria were met for all diagnoses. RESULTS: In 42 patients with PASC, five categories of sleep disorder syndromes were observed following a sleep clinic evaluation, including obstructive sleep apnea, chronic insomnia disorder, primary hypersomnia, REM behavior disorder (RBD), and new onset circadian phase delay. Seven patients met criteria for idiopathic hypersomnia, and two had narcolepsy type 2. RBD patients were infected in three different waves; circadian disturbance patients were all infected in the winter wave of 2020/21, and the primary hypersomnolence group occurred during all waves, predominantly the initial wave of 2020. A peculiar form of insomnia was a persistent loss of sleep regularity. CONCLUSIONS: Specific sleep symptoms/syndromes are reported in this select group of patients with PASC/Long Covid. As new onset sleep complaints are prevalent in PASC, we recommend a complete clinical and investigative sleep evaluation for persistent severe sleep symptoms following COVID-19 infection.

Exploring the Congruence of actigraphy and the Pediatric Autism Insomnia rating Scale.

OBJECTIVE/BACKGROUND: Insomnia is common in children with autism spectrum disorder (ASD). We recently developed and validated the 21-item Pediatric Autism Insomnia Rating Scale (PAIRS). This report explores the associations and agreements between actigraphy and PAIRS. PARTICIPANTS METHODS: Children with ASD, with and without sleep problems, were assessed with a battery of parent-rated and clinician measures (N = 134). In a subset (n = 70), a wrist-worn actigraph measured sleep for five consecutive nights. Parents completed logs for scoring sleep intervals. Spearman correlations evaluated associations with the PAIRS and actigraphy indices (sleep onset latency = SOL, wake after sleep onset = WASO, total sleep time = TST, sleep efficiency = SE%). Agreements on "poor sleepers" based on PAIRS total score (≥33) and conventional thresholds for TST and SE% were evaluated with Cohen's Kappa and McNemar's test. RESULTS: Actigraphy data were averaged over 4.64 ± 0.68 nights in 70 children (mean age = 7.3 ± 2.9, 74.3 % male). There were no significant correlations between PAIRS and any actigraphy indices. On TST, 48.6 % (n = 34) and on SE% 52.9 % (n = 37) were classified as "poor sleepers" compared to 32.9 % (n = 23) on PAIRS (kappa = 0.11 for TST and 0.27 for SE%). P-values on McNemar's Chi square test for PAIRS with TST and with SE% were 0.072 and 0.011, respectfully. CONCLUSIONS: These results suggest that actigraphy and PAIRS do not agree. Actigraphy TST captures movement and an estimate of specific sleep parameters. PAIRS is a broader measure that incorporates sleep disturbance and sleep-related impairment.

Association between depression severity and trouble sleeping: A population-based study.

This study investigates the association between insomnia and depression severity, exploring sleep disturbances in individuals with depression. The aim is to establish a new foundation for managing patients with co-occurring depression and insomnia, using 2015 to 2016 National Health and Nutrition Examination Survey (NHANES) data. We employed a cross-sectional design, using NHANES data from 2015 to 2018. The study included 11,261 participants after excluding incomplete data. Depression severity, assessed using Patient Health Questionnaire-9 (PHQ-9) scores, served as the exposure variable. We considered various demographic and lifestyle factors as covariates in the multivariate adjustment model. Statistical analyses adhered to CDC recommendations, with sample weights incorporated to account for NHANES' complex sample design. Our study, encompassing 19,225 participants, revealed that higher PHQ-9 scores correlated with an increased likelihood of sleep disorders. In the fully adjusted model, a positive association emerged between PHQ-9 scores and trouble sleeping (OR = 3.95, 95% CI: 3.35-4.66, P < .0001). This relationship displayed an inverted U-shaped curve, with an inflection point at 28. Subgroup analysis and interaction tests indicated no reliance on factors such as gender, age, marital status, or BMI for the connection between depression severity and trouble sleeping (all P for interaction > .05). We identified a significant inverted U-shaped correlation between sleep disturbances and depression severity. This underscores the crucial importance of assessing sleep disorder risks in individuals with varying degrees of depression severity, facilitating personalized therapeutic interventions.

Consumption patterns and factors associated with inappropriate prescribing of benzodiazepines in Primary Health Care settings.

BACKGROUND: Benzodiazepines are frequently prescribed to treat anxiety and insomnia, but long-term use has been associated with the development of dependence, tolerance, and cognitive decline, especially among older adults. This study aimed to investigate the pattern of consumption and factors associated with inappropriate prescribing of benzodiazepines in primary health care. METHODS: This is a cross-sectional analytical study, using dispensing records of diazepam, clonazepam, and nitrazepam from public pharmacies in a Brazilian municipality between 2018 and 2022. Metrics for benzodiazepine consumption were DDD (Defined Daily Dose) and DDD/1000PD (per 1000 population per day). Long-term/prolonged benzodiazepine use was defined as consuming at least 90 DDD and at least 2 dispensations per year. To ascertain associations between long-term use and predictor variables, a multivariate logistic regression model was utilized. FINDINGS: A total of 40402 participants were included, with an average age of 55 years (SD = 0.30), 38.5% were older aged. Diazepam and nitrazepam exceeded the daily dose recommended. There was a reduction in diazepam consumption during the study period, as calculated by DDD/1.000PD, while the consumption of other benzodiazepines remained stable. However, a significant increase in diazepam consumption is noted when considering the last decade. Prolonged use was observed in 29.1% of participants, with a significant prevalence among the older people (34.8% of them were long-term users) and advancing age was identified as a risk factor for long-term use. Higher PDDs were also associated with long-term use and aging. Participants who used different benzodiazepines during the period had a higher risk of prolonged use. CONCLUSIONS: These results provide insights into the prevalence of problematic utilization of benzodiazepines in primary health care. Authorities and health care providers must take steps to encourage gradual cessation of prolonged benzodiazepine prescriptions and the embrace of suitable strategies for addressing anxiety and insomnia within primary health care settings.

Predictive effect of insomnia on quality of life in last trimester pregnant women: A cross-sectional study.

This study was conducted to determine the predictive effect of insomnia on quality of life in last trimester pregnant women. This study is a cross-sectional study. The sample of the study consisted of 309 women who were pregnant in the last trimester and were followed up in the university hospital. The data was collected using Women's Health Initiative Insomnia Rating Scale(WHIIRS), World Health Organization Quality of Life Scale Short Form(WHOQOL-BREF). The Kolmogorov-Smirnov test was used to evaluate compliance with the normal distribution. Pearson correlation test used to examine the relationships between life quality subscales, discomforts during pregnancy, chronic disease, psychiatric disease, working status and insomnia. Hierarchical multiple linear regression analysis was used to determine the predictive factors of quality of life. There was a negative relationship between having problems in pregnancy and the physical domain and the psychological domain of quality of life. When working status and discomforts during pregnancy were controlled, it was determined that insomnia was an important predictor of physical, psychological, social relations and environmental areas of quality of life (respectively 21%, 6%, 5%, 4%,). As a result, it can be said that insomnia is one of the important areas that should be intervened to improve the quality of life in pregnant women.

Cette étude a été menée pour déterminer l'effet prédictif de l'insomnie sur la qualité de vie des femmes enceintes au dernier trimestre. Il s'agit d'une étude transversale. L'échantillon de l'étude était composé de 309 femmes enceintes au dernier trimestre et suivies à l'hôpital universitaire. Les données ont été recueillies à l'aide de l'échelle d'évaluation de l'insomnie de la Women's Health Initiative (WHIIRS), de l'échelle abrégée de la qualité de vie de l'Organisation mondiale de la santé (WHOQOL-BREF). Le test de Kolmogorov-Smirnov a été utilisé pour évaluer la conformité à la distribution normale. Le test de corrélation de Pearson a été utilisé pour examiner les relations entre les sous-échelles de qualité de vie, les désagréments pendant la grossesse, les maladies chroniques, les maladies psychiatriques, le statut professionnel et l'insomnie. Une analyse de régression linéaire multiple hiérarchique a été utilisée pour déterminer les facteurs prédictifs de la qualité de vie. Il y avait une relation négative entre le fait d'avoir des problèmes pendant la grossesse et le domaine physique et le domaine psychologique de la qualité de vie. En prenant en compte le statut professionnel et les désagréments pendant la grossesse, il a été déterminé que l'insomnie était un prédicteur important de la qualité de vie physique, psychologique, sociale et environnementale (respectivement 21 %, 6 %, 5 %, 4 %). Par conséquent, on peut dire que l'insomnie est l'un des domaines importants sur lesquels il faut intervenir pour améliorer la qualité de vie des femmes enceintes.

A Retrospective Observational Study to Understand Medication Utilization and Lines of Treatment in Patients With Insomnia Disorder.

Background: Insomnia is a common sleep disorder, associated with multiple health concerns. Current medications for insomnia are associated with higher safety risks if clinical practice guidelines or monograph recommendations are not followed. This study aims to understand real-world prescribing practices among patients with insomnia in Canada, including medication utilization, potentially inappropriate medication use, cost incurred, and lines of treatment.Methods: This retrospective observational study utilized longitudinal drug claims data from 2018 to 2020 from the Canadian IQVIA National Private Drug Plan and Ontario Drug Benefit databases. Patients with any claims for medications approved for insomnia in Canada were identified. Four types of inappropriate medication usage were defined: (1) elevated daily dose; (2) extended duration of use for benzodiazepines (BZD) and/or Z-drugs; (3) combination use; and (4) opioid overlap with BZD and/or Z-drugs.Results: In 2019, 597,222 patients with insomnia were identified; 64% were female, with an average age of 55 years. Inappropriate medication use was noted in 52.5% of adult patients (aged 18-65 years) and 69.5% of senior patients (aged >65 years). Extended duration was the most common inappropriate medication usage category. The annual cost of medications for insomnia was $54.8 million, and $30.3 million (55.2%) met inappropriate medication use criteria.Conclusion: High prevalence of inappropriate medications usage in insomnia raises serious safety concerns for patients suffering from insomnia, particularly seniors, while also placing a substantial burden on the Canadian public and private health systems. This highlights an unmet need for better education regarding current guidelines and more effective and safer treatment options.

Increased risk of depression and associated symptoms in poststroke aphasia.

Poststroke aphasia hinders patients' emotional processing and social adaptation. This study estimated the risks of depression and related symptoms in patients developing or not developing aphasia after various types of stroke. Using data from the US Collaborative Network within the TriNetX Diamond Network, we conducted a retrospective cohort study of adults experiencing their first stroke between 2013 and 2022. Diagnoses were confirmed using corresponding International Classification of Diseases, Tenth Revision, Clinical Modification codes. Patients were stratified by poststroke aphasia status and stroke type, with propensity score matching performed to control for confounders. The primary outcome was depression within one year post-stroke; secondary outcomes included anxiety, fatigue, agitation, emotional impact, and insomnia. Each matched group comprised 12,333 patients. The risk of depression was significantly higher in patients with poststroke aphasia (hazard ratio: 1.728; 95% CI 1.464-2.038; p < 0.001), especially those with post-hemorrhagic-stroke aphasia (hazard ratio: 2.321; 95% CI 1.814-2.970; p < 0.001). Patients with poststroke aphasia also had higher risks of fatigue, agitation, and emotional impact. Anxiety and insomnia risks were higher in those with post-hemorrhagic-stroke aphasia. Poststroke aphasia, particularly post-hemorrhagic-stroke aphasia, may increase the risks of depression and associated symptoms, indicating the need for comprehensive psychiatric assessments.

Comparative insomnia prevalence between geriatrics lived in urban and rural areas: a multicenter nationwide study analysis.

AIMS: Insomnia is a common complaint among older adults. However, the comparative prevalence between older adults living in urban versus rural areas remains under-researched. This study aims to validate the overall prevalence of insomnia among older adults in Indonesia and investigate the comparative prevalence between older adults living in urban and rural areas. METHODS: The data were derived from the 2018 Indonesian Basic Health Research Study. We included a total of 93,830 older participants aged > 60 years old who completed the insomnia questions. The prevalence and regression models were analyzed using the SPSS software. RESULTS: The insomnia group has a higher age compared to the non-insomnia group (P < 0.05). Insomnia is more prevalent in females compared to males (P < 0.05). When classified by age groups (60-64, 65-69, 70-74, and > 75 years old), the prevalence of insomnia was 20%, 21%, 23%, and 24%, respectively. The prevalence of insomnia among older individuals living in rural areas was higher compared to those living in urban areas. In addition, increasing age, being female, unemployed, having comorbidities, being less active, and drinking alcohol are associated with insomnia symptoms. CONCLUSION: The findings of this study indicated that the prevalence of insomnia is high among older adults in Indonesia, with older adults living in rural areas exhibiting a higher prevalence compared to those living in urban areas. Our findings strengthen the importance of sleep management in clinical or community settings.

Outpatient Prescriptions for Insomnia Medications During the First Year Following Combat-Related Amputations.

INTRODUCTION: Sleep-related disorders are associated with pain, fatigue, and deficits in cognitive performance, which may interfere with successful rehabilitation. The study objectives were to (1) quantify outpatient prescriptions for insomnia medications during the first year following combat-related amputations, (2) examine longitudinal changes in prescriptions for insomnia medications, and (3) analyze patient characteristics associated with prescriptions for insomnia medications. MATERIAL AND METHODS: This was a retrospective study of DoD casualty records from the Expeditionary Medical Encounter Dataset and prescriptions for outpatient medications from the Pharmacy Data Transaction Service. Patients were a total of 1,651 U.S. service members who sustained major limb amputations in Operations Iraqi and Enduring Freedom from 2001 through 2017 and had outpatient prescriptions for any medication during the first year postinjury. Prescriptions for medications recommended for insomnia were low-dose antidepressants, anxiolytic sedatives, benzodiazepines, melatonin receptor agonist, and low-dose quetiapine. These prescription medications were analyzed by medication type, postinjury time, and patient characteristics during the first year postinjury. RESULTS: During the first year postinjury, 78% of patients (1,291 of 1,651) had outpatient prescriptions for insomnia medications, primarily anxiolytic sedative drugs (e.g., zolpidem), averaging a total of 86 prescription days (median = 66). The prevalence of these prescriptions declined substantially during the first year, from 57% of patients during the first quarter to 28% during the fourth quarter postinjury. In univariate analyses, multiple patient characteristics, including high Injury Severity Score, continued opioid and non-opioid analgesic prescriptions, and diagnoses of chronic pain, mood disorder, and posttraumatic stress disorder, were significantly associated with higher prevalence and duration of outpatient prescriptions for insomnia medications. CONCLUSIONS: The present results indicate a high prevalence of outpatient prescriptions for insomnia medications following combat-related amputations, a prevalence that is substantially higher than previously reported among active duty personnel. These findings can inform DVA/DoD guidelines for amputation care and insomnia among military subpopulations. The results highlight the need for more research on the treatment of insomnia during early postinjury rehabilitation among patients who sustained serious combat injuries.

Reliability and validity of the Chinese version of the doomscrolling scale and the mediating role of doomscrolling in the bidirectional relationship between insomnia and depression.

BACKGROUND: Doomscrolling behavior is very common among college students. The purpose of this study was to evaluate the reliability and validity of the Chinese version of the Doomscrolling Scale, thus providing a scientific basis for its application among Chinese university students. METHODS: The Chinese version of Doomscrolling Scale was developed through translation and revision of the original scale, conducting item and factor analysis, and validating it with validation factor analysis. The psychometric properties of the Doomscrolling Scale were assessed in 2885 Chinese university students. RESULTS: The internal consistency coefficients, two-month test-retest reliability, and split-half reliability of the Chinese version of the Doomscrolling Scale (including the 15-item and the 4-item short version) were high, and the mono-factorial scales fitted well to the theoretical model. Scores on the Chinese version of the Doomscrolling Scale were significantly associated with depression, anxiety, and smartphone addiction. The structural equation model indicates that doomscrolling can mediate the bidirectional relationship between insomnia disorder and depression. CONCLUSIONS: The revised Chinese version of the Doomscrolling Scale is valid and reliable, which can facilitate research in this field. The association between doomscrolling and various mental disorders has been confirmed, and further research should be conducted to investigate its mechanisms of action.

Study on chemical characterization and sleep-improvement function of Prunella vulgaris L. based on the functional components.

Prunella vulgaris L. (P. vulgaris) has great application value and development prospects in improving sleep. In this study, we continued to evaluate the sleep-improvement function and mechanism of P. vulgaris from both chemical characterization and function based on sleep-improvement functional ingredients, rosmarinic acid and salviaflaside, screened out in the previous stage as the index components. The chemical constituents of P. vulgaris and its phenolic acid fraction were characterized by the UPLC-MSn technology. The quality of the sleep-improvement phenolic acid fraction of P. vulgaris was scientifically evaluated by fingerprints combined with quantitative analysis of rosmarinic acid and salviaflaside. The function of phenolic acid parts of P. vulgaris in improving sleep was verified by different insomnia models including the PCPA-induced insomnia model and surface platform sleep deprivation model. HE staining was used to observe the effect of P. vulgaris on the morphology of nerve cells in different brain regions. In vivo experiments and molecular docking explored the sedative-hypnotic effects of functional ingredients of P. vulgaris. All these results investigated the material basis and mechanism of P. vulgaris to improve sleep from multiple perspectives, which contribute to providing a basis for the development of functional food to improve sleep.

Using the behaviour change wheel to develop a tailored intervention to overcome general practitioners' perceived barriers to referring insomnia patients to digital therapeutic sleepio.

BACKGROUND: Digital therapeutic Sleepio has proven effective in improving sleep quality and decreasing symptoms of anxiety. The National Institute for Health and Care Excellence (NICE) guidance recommends Sleepio as an alternative treatment to usual sleep hygiene education and hypnotic medications. General practitioners (GPs) play a critical role in the adoption of digital therapeutics in patient care. Previous interventions did not adopt theoretical frameworks to systematically understand GPs behaviour toward referring patients to digital therapeutics. OBJECTIVES: This study aimed to report the systematic and comprehensive development of an intervention to encourage GPs to refer insomnia patients to Sleepio, using the Behaviour Change Wheel (BCW). METHODS: The eight steps outlined in the BCW were followed to develop an intervention. The Capability Opportunity Motivation-Behaviour Self-Evaluation Questionnaire (COM-B-Qv1) was adopted to understand GPs perceived facilitators and barriers to refer insomnia patients to Sleepio. The Behaviour Change Technique Taxonomy Version 1 (BCTv1) was thereafter used to identify possible strategies that could be used to facilitate changes in GPs' behaviour in relation to Sleepio. RESULTS: The BCW design process resulted in the identification of five intervention functions, three policy categories and five behaviour change techniques (BCTs) as potential active components for an intervention. The intervention includes providing GPs with an orientation about using Sleepio to improve their knowledge and confidence, sending visual reminders to GPs to recommend Sleepio to their patients, providing ongoing technical support. CONCLUSION: The BCW can be successfully applied through a systematic process to understand the drivers of GPs' behaviour and to develop an intervention that can encourage them to refer insomnia patients to Sleepio.

Acupuncture modulates emotional network resting-state functional connectivity in patients with insomnia disorder: a randomized controlled trial and fMRI study.

BACKGROUND: Insomnia disorder (ID) is one of the most common sleep problems, usually accompanied by anxiety and depression symptoms. Functional magnetic resonance imaging (fMRI) study suggests that both poor sleep quality and negative emotion are linked to the dysregulation of brain network related to emotion processing in ID patients. Acupuncture therapy has been proven effective in improving sleep quality and mood of ID patients, but the involved neurobiological mechanism remains unclear. We aimed to investigate the modulation effect of acupuncture on resting-state functional connectivity (rsFC) of the emotional network (EN) in patients experiencing insomnia. METHODS: A total of 30 healthy controls (HCs) and 60 ID patients were enrolled in this study. Sixty ID patients were randomly assigned to real and sham acupuncture groups and attended resting-state fMRI scans before and after 4 weeks of acupuncture treatment. HCs completed an MRI/fMRI scan at baseline. The rsFC values within EN were calculated, and Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), Hyperarousal Scale (HAS), and actigraphy data were collected for clinical efficacy evaluation. RESULTS: Resting-state FC analysis showed abnormalities in rsFC centered on the thalamus and dorsolateral prefrontal cortex within EN of ID patients compared to HCs. After real acupuncture treatment, rsFC of the anterior cingulate cortex, hippocampus, and amygdala were increased compared with the sham acupuncture group (p < 0.05, FDR corrected). In real acupuncture group, the rsFC value was decreased between left amygdala and left thalamus after 4 weeks of treatment compared with baseline. A trend of correlation was found that the increased rsFC value between the right amygdala and left hippocampus was positively correlated with the decreased HAMA scores across all ID patients, and the decreased left amygdala rsFC value with the left thalamus was negatively correlated with the increased sleep efficiency in the real acupuncture group. CONCLUSION: Our findings showed that real acupuncture could produce a positive effect on modulating rsFC within network related to emotion processing in ID patients, which may illustrate the central mechanism underlying acupuncture for insomnia in improving sleep quality and emotion regulation.

Effectiveness of digital Cognitive-Behavioural Therapy for Insomnia in patients with musculoskeletal complaints and insomnia in primary care physiotherapy: study protocol for a randomised controlled trial.

INTRODUCTION: Insomnia is prevalent among patients visiting physiotherapists due to musculoskeletal complaints and associated with poorer pain prognosis. Cognitive-Behavioural Therapy for Insomnia (CBT-I) may be effective for improving sleep quality and pain-related outcomes in these patients, but its availability and utility are limited in daily physiotherapy practice. The aim of this randomised controlled trial (RCT) is to evaluate the effectiveness of digital CBT-I in addition to usual treatment in patients with chronic musculoskeletal complaints and insomnia, compared with usual treatment only. METHODS AND ANALYSIS: In this RCT, eligible and consenting participants will be randomised (1:1 ratio) to one of two interventions: (1) digital CBT-I adjunct to physiotherapy treatment or (2) usual physiotherapy treatment. Patients with musculoskeletal complaints and insomnia visiting a physiotherapist in Norway will be invited to participate in the study. We aim to include 188 participants to detect a difference in the primary outcome. Outcome variables will be assessed at baseline (prior to randomisation) and at 6-week, 3-month, 6-month and 12-month follow-up. The primary outcome is between-group difference in insomnia severity, assessed with the Insomnia Severity Index (0-28 points) at 3 months. Secondary outcomes include between-group differences in pain intensity, physical function, work ability, health-related quality of life, mental distress, and self-reported use of sleep and pain medication. Exploratory analyses will identify patient characteristics influencing the effect of the digital intervention. ETHICS AND DISSEMINATION: This trial is approved by the Regional Committee for Medical and Health Research Ethics in Central Norway (Ref. 2023/533381). The results of the trial will be published in peer-review journals and disseminated at national and international conferences. TRIAL REGISTRATION NUMBER: ISRCTN91221906.

Psychometric Evaluation of the Insomnia Severity Index in U.S. College Students.

Psychometric properties of the Insomnia Severity Index (ISI) were analyzed in U.S. college samples. ISI items and total score with sleep and psychosocial questionnaires were examined in Experiment I. ISI diagnostic accuracy in a clinical sample with and without insomnia was assessed in Experiment II. ISI test-retest validity, confirmatory factor analysis (CFA), and item response theory via graded response model (GRM) were assessed in Experiment III. Results indicated analogous ISI and sleep diary items showed moderate correlations (r1 = .40; r2 = .45). The ISI total had weak to strong correlations with other indicators of sleep-related disturbance (rs = .25-.62). The ISI had weak to moderate correlations with psychosocial measures commonly associated with insomnia (rs = .10-.57). The diagnostic accuracy of the ISI was very high (area under the curve [AUC] = .999). Sensitivity and specificity were maximized at a cutoff score ≥ 8. The ISI demonstrated good test-retest reliability (ICC = .87). CFA revealed a three-factor model for two study samples and GRM indicated better ability of the ISI to assess moderate (Sample III) and moderate to high (Sample I) levels of insomnia severity. The ISI demonstrated good psychometric properties and appears generally valid for screening insomnia disorder and assessing insomnia severity in college students. Overlap with psychological symptoms suggests caution while interpreting these constructs independently.

The Adolescent Insomnia Questionnaire: the Turkish validity and reliability study.

OBJECTIVE: This study aimed to evaluate the Turkish validity and reliability of the Adolescent Insomnia Questionnaire. METHODS: The study was carried out with 265 adolescents. Data were collected with the Adolescent Insomnia Questionnaire and the Cleveland Adolescent Sleepiness Questionnaire. Exploratory factor analysis and confirmatory factor analysis were used to analyze the construct validity of Adolescent Insomnia Questionnaire. The scale reliability was tested using test-retest, Cronbach's α test, Pearson correlation analysis, and inter-item correlation analysis. RESULTS: The Cronbach's α coefficients were found to be above 0.80 for all sub-dimensions and the total scale. Correlations between Adolescent Insomnia Questionnaire and Cleveland Adolescent Sleepiness Questionnaire scores were positively highly significant. The test-retest correlation analysis of Adolescent Insomnia Questionnaire was 0.675. The results of confirmatory factor analysis were χ2/df=2.861, comparative fit index=0.966, incremental fit index=0.966, Tucker-Lewis index=0.956, normed fit index=0.949, root-mean-square error of approximation=0.084. The suitability of the data for exploratory factor analysis was evaluated with Bartlett's test of sphericity (p<0.05), and the sample adequacy was evaluated with the Kaiser-Meyer-Olkin test (0.77). CONCLUSION: The Adolescent Insomnia Questionnaire Turkish version is a valid and reliable tool for measuring insomnia in adolescents aged 11-18 years. Adolescent Insomnia Questionnaire is a brief, practical, self-reported, age-appropriate, easily applicable, valid, and reliable tool in Turkish. This is the first Turkish validity and reliability study of Adolescent Insomnia Questionnaire.

The Association Between Sleep Disturbances and Perceived Stress in Substance Use Disorder Treatment.

Abstract.Introduction: Sleep disturbances and elevated stress levels are commonly reported among individuals seeking treatment for substance use disorders (SUDs). However, it remains unclear whether the relationship between sleep and stress differs based on the primary substance of use or if there are commonalities across different substances. This study aimed to investigate the association between sleep disturbances and perceived stress among individuals in SUD treatment and examine whether primary substance influences this relationship.Method: A sample of 4,201 individuals from 59 SUD treatment programs completed assessments including the Insomnia Severity Index and Perceived Stress Scale in 2021. Cross-sectional and longitudinal analyses were conducted to evaluate the relationship between sleep and stress across different primary substances during treatment.Results: The results demonstrated that higher stress was associated with more severe insomnia, and vice versa, both at treatment intake and over the course of treatment, regardless of primary substance. Persons using heroin/ fentanyl evidenced a stronger association of sleep on stress, and persons using cocaine evidenced a stronger relationship of stress on sleep.Discussion: The findings suggest that sleep/stress associations are ubiquitous across different classes of drugs, although sleep might have more influence on stress in persons primarily using heroin/ fentanyl, and stress might have more influence on sleep in persons primarily using cocaine, relative to other substances. Interventions targeting either sleep or stress could have positive effects on SUD outcomes, but further research is needed to investigate the underlying neurobiological mechanisms and inform the development of effective interventions for sleep and stress in SUD populations.
