Which should be targeted first? The comorbidity of sleep disturbances and anxiety symptoms among adolescents: Cross-sectional and longitudinal network analyses.

Background: The comorbidity of sleep disturbances and anxiety is well-established, but which symptoms to prioritize for intervention remains unclear. Academic stress, a key factor worsening both, is common among adolescents facing growing academic demands. Understanding how it affects both comorbidities from a symptomatology perspective is crucial for developing targeted interventions.

The longitudinal association between problematic Internet use and psychotic-like experiences in adolescents: Mediated by sleep disturbance and moderated by psychological resilience.

Problematic Internet use (PIU) has been empirically identified as a risk factor for future psychotic-like experiences (PLEs) among adolescents. This study aimed to examine the short-term predictive role of PIU on PLEs in adolescents and investigate their underlying mechanisms, focusing on the mediating role of sleep disturbance and the moderating role of psychological resilience. A total of 27,260 Chinese adolescents (52.

Changes in insomnia symptoms among compulsory education students in China after the "Double Reduction" policy: a two-wave longitudinal study.

Objective: In July 2021, the "Double Reduction" policy was introduced in China, aiming to alleviate the burden of excessive homework and off-campus tutoring for students in the compulsory education stage. The purpose of this study is to explore the changes in students' insomnia symptoms and related factors after the policy implementation. Meanwhile, sex differences were further examined.

Is Bedtime Procrastination Related to Multidimensional Sleep Health? Evidence from Samples of Different Educational Stages (Aged 10-25) in China.

Bedtime procrastination has been associated with poorer sleep health, but evidence for this association is not sufficient. This cross-sectional study aimed to investigate the relationship between bedtime procrastination and multidimensional sleep health among students at different educational stages (from elementary school to college) in China, and further examine the moderating role of psychological distress in the procrastination-sleep health link. A total of 3539 students (M = 15.

A new way to conceptualize intolerance of uncertainty among adolescents: Embracing the network perspective.

Intolerance of uncertainty (IU), a pivotal transdiagnostic risk factor in psychopathology, is defined as a dispositional incapacity to withstand uncertainty distress, driving maladaptive cognitive, emotional and behavioural reactions to uncertainty. However, the intricate interplay among these components, particularly in adolescents, remains underexplored; yet understanding this interplay is crucial for supporting mental health. To address this gap, we employed a network approach to conceptualize IU in 5672 non-clinical Chinese adolescents (M = 14.

Sleep disturbance and internalizing symptoms in adolescents: a moderated mediation model of self-control and mindfulness.

Objectives: Despite accumulating evidence regarding the impact of sleep disturbance on internalizing symptoms among adolescents, the underlying psychological mechanisms remain inadequately explored. This study aimed to investigate a conceptual framework elucidating how sleep disturbance influences internalizing symptoms in adolescents through the mediating role of self-control, with mindfulness as a moderator.

Methods: In this cross-sectional study, 1876 Chinese adolescents (Mage = 14.

Negative life events and sleep disturbance among adolescents: Intolerance of uncertainty as mediator and moderator.

Background: While negative life events (NLEs) have been linked to an increased risk of sleep disturbance among adolescents, the mechanisms of this impact still lack further examination. The current study aimed to explore whether intolerance of uncertainty (IU), a dispositional transdiagnostic vulnerability factor for psychopathology, could act as a mediator and/or moderator in the link from NLEs to sleep disturbance.

Methods: A longitudinal nested subsample of 54,240 Chinese adolescents (aged 9-19) were surveyed at baseline (Timepoint 1) and six months later (Timepoint 2).

Changes in sleep disturbance among Chinese adolescents: A population-based online survey.

Objective: Sleep disturbance is prevalent among adolescents but little is known about the short-term changes among Chinese adolescents. The study aimed to explore the prevalence and change patterns of sleep disturbance and identify its risk and protective factors.

Methods: Data were collected online from April 21st to May 12th, 2021 (Time 1, T1) and December 17th to 26th, 2021 (Time 2, T2).

Profiles of Intolerance of Uncertainty Among 108,540 Adolescents: Associations with Sociodemographic Variables and Mental Health.

Intolerance of uncertainty (IU) is widely considered a transdiagnostic risk and maintaining factor for psychiatric disorders. However, little is known about the overall nature and profile of IU among adolescents. This study aims to investigate the profiles of IU among Chinese adolescents and explore their associations with sociodemographic characteristics and mental health problems.

A comparative study of mental health status among left-behind, migrant, and local adolescents in China.

Objective: Influence of migration on mental impairments among adolescents has been well assessed. However, there lack empirical data on multiple mental health problems and comparisons of children who suffer from different parental migration. This study aims to compare the mental health status among left-behind adolescents (LBA), migrant adolescents (MA), and local adolescents (LA).

Does sleep disturbance predicts posttraumatic stress disorder and depression among college students during COVID-19 lockdown? A longitudinal survey.

Aim: To examine the cross-sectional and longitudinal associations between self-reported sleep disturbances, posttraumatic stress disorder (PTSD) and depression in a large cohort of Chinese adolescents experiencing the COVID-19 pandemic.

Methods: Participants were 67905 Chinese college students in the two-wave longitudinal web-based survey during early COVID-19 outbreak (Time1, T1: Feb 3rd to 10th, 2020) and initial remission period (Time2, T2: March 24th to April 3rd, 2020). The Youth Self Rating Insomnia Scale (YSIS), 6-Item Impact of Event Scale (IES-6), and 9-Item Patient Heath Questionnaire (PHQ-9) were used to assess adolescents' sleep, PTSD, and depressive symptoms, respectively, at T1 and T2.

Using network analysis to explore the key bridge symptoms between posttraumatic stress symptoms and posttraumatic growth among survivors 10 years after the Wenchuan earthquake in China.

Despite previous research has illustrated there is high-coexistence between posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) in the aftermath of traumatic events, few studies have conceptualized the coexistence mechanism of the two psychological phenomena. Using the network analysis, this study aimed to identify the key bridge symptoms and compare sex differences between PTSD symptoms and PTG elements in survivors 10 years after the Wenchuan earthquake in China. A total of 744 survivors 10 years after the Wenchuan earthquake in China completed self-reported questionnaires on demographics, PTSD symptoms (4-item of Posttraumatic Stress Disorder Checklist), and PTG (10-item of Posttraumatic Growth Inventory).
