Anxiety in Adolescents

Global Prevalence of Social Anxiety Disorder in Children, Adolescents and Youth: A Systematic Review and Meta-analysis

Social anxiety disorder is a prevalent mental health condition that significantly impairs social interactions, academic performance, and professional functioning in children, adolescents, and youth. This study aimed to investigate the global prevalence of social anxiety disorder across these developmental stages. Six electronic databases (PubMed, Scopus, Web of Science, Embase, ScienceDirect and Google Scholar) were systematically searched for studies related to the prevalence of social anxiety disorder in children, adolescents and youth. Random-effects models were employed for data analysis and Comprehensive Meta-Analysis Version 2.0. Heterogeneity was assessed using the I2 index. A total of 38 studies were included in the final analysis. The global prevalence of social anxiety disorder was estimated to be 4.7% in children, 8.3% in adolescents, and 17% in youth. These findings suggest a progressive increase in the prevalence of SAD across these developmental stages. Considering the prevalence of social anxiety disorder in this study, policymakers can use the findings of this study to inform and develop effective prevention strategies for individuals and communities most susceptible to this disorder.

Adolescent internet use predicts higher levels of generalized and social anxiety symptoms for girls but not boys

Past research suggests that internet use can increase the risks of internalizing symptoms in adolescents. However, bidirectional relationships between adolescent internet use and anxiety symptoms have received very little attention. Furthermore, few studies have examined these links according to sex. The present study attempts to fill this gap by investigating longitudinal associations between Canadian boys' and girls' internet use and symptoms of generalized anxiety and social anxiety using data from the Quebec longitudinal Study of Child Development. A sample of 1324 adolescents (698 girls, 626 boys) self-reported the number of hours per week they spent on the internet and their symptoms of generalized and social anxiety at ages 15 and 17. We estimated two cross-lagged panel models with social or generalized anxiety symptoms and internet use at age 15 predicting those same variables at age 17. Sex was used as a grouping variable and socioeconomic status was included as a control variable. Internet use at 15 predicted generalized and social anxiety symptoms at age 17 in girls, but not boys. Social and generalized anxiety symptoms at age 15 did not predict internet use at age 17 for both boys and girls. These results suggest that internet use can be a significant risk factor for the development of anxiety symptoms in adolescent girls. Girls may be more vulnerable to the negative effects of internet use due to increased sensitivity to social comparisons. Thus, helping girls develop healthier internet use habits should be a target for promoting their mental health.

Outpatient care for adolescents' and young adults' mental health: promoting self- and others' understanding through a metacognitive interpersonal therapy-informed psychological intervention

Introduction

Psychological distress may result in impairment and difficulty understanding oneself and others. Thus, addressing metacognitive issues in psychotherapy may improve psychopathology in adolescents and young adults (AYAs). We aimed to compare metacognitive interpersonal therapy (MIT)-informed psychotherapy with other treatment-as-usual (TAU) therapies.

Methods

We administered the Global Assessment of Functioning (GAF) scale, the Clinical Global Impressions-Severity (CGI-S) scale, and the Brief Psychiatric Rating Scale (BPRS) at baseline (BL) and at treatment termination (the endpoint was at 6 months and any last results obtained before that term were carried forward in analyzes). Patients received concomitant psychiatric and psychological treatment.

Results

Sixty AYAs were involved in the study. There was a significant reduction in symptomatology after the intervention. Twelve patients (17%) dropped out; treatment adherence was 83%. In the MIT group, 2 patients dropped out (11%), and in the TAU group, 9 patients dropped out (19%). All scales showed a significant reduction in symptoms between baseline (BL) and the 6-month endpoint: GAF (χ2 = 6.61, p < 0.001), BPRS (χ2 = 6.77, p < 0.001), and CGI (χ2 = 7.20, p < 0.001). There was a greater efficacy for the MIT group in terms of symptom reduction on the BPRS (t = 2.31; p < 0.05).

Conclusion

The study confirmed the efficacy of early and integrated care in adolescence and suggested greater symptom reduction for a psychotherapeutic intervention focused on stimulating mentalization skills. The study indicates the usefulness of this type of approach in the treatment of adolescent psychopathology. Due to the small sample size, the results need replication.

Cross-sectional and longitudinal associations of adherence to the 24-hour movement guidelines with mental health problems among Chinese adolescents

OBJECTIVE

This study aimed to examine the cross-sectional and longitudinal associations between meeting the 24-Hour Movement Guidelines (recommendations for the optimal amount of moderate-to-vigorous physical activity, screen time, and sleep duration per day) and mental health problems among Chinese adolescents.

METHODS

A two-wave longitudinal survey was conducted in Huizhou, Guangdong province. A total of 906 junior high school students were recruited in the six-month follow-up survey. Moderate-to-vigorous physical activity, screen time, sleep duration, anxiety symptoms (GAD-7 score), and depressive symptoms (PHQ-9 score) were measured using a self-administered questionnaire. At baseline, participants were classified as meeting: 1) no recommendation, 2) one recommendation, 3) two recommendations, or 4) all three recommendations.

RESULTS

Overall, the proportions of adolescents meeting moderate-to-vigorous physical activity, screen time, and sleep recommendations at T₁ were 33.3%, 68.2%, and 64.7%, respectively. Cross-sectionally, the severity of anxiety and depressive symptoms at T₁ significantly decreased as the number of recommendations met increased (adjusted regression coefficients [95% CI] for three recommendations met versus none: -2.80 [-4.05, -1.55] and - 3.42 [-4.85, -1.99], respectively). Longitudinally, adolescents who met three recommendations at T₁ displayed lower anxiety and depressive symptoms six months later than those who did not (adjusted regression coefficients [95% CI]: -1.00 [-1.98, -0.02] and - 1.43 [-2.53, -0.32], respectively). Furthermore, meeting three recommendations was associated with the alleviation of depressive symptoms (adjusted OR [95% CI]: 0.39 [0.17, 0.90]).

CONCLUSIONS

Promoting adolescents to adhere to the 24-Hour Movement Guidelines could be considered an intervention target for mental health problems at a population level.

Mental health interventions in adolescence

Adolescent mental health (MH) disorders with striking prominence include anxiety, self-harm and depression. The current review aims to highlight high-quality reviews of novel interventions, mainly Cochrane reviews, and/or quality meta-analyses published between 2019 and 2022 on three adolescent mental health challenges. Recent evidence about the effectiveness of psychosocial interventions is encouraging. However, the shift to virtual treatment methods during the pandemic was supported by a relatively thin body of research. Future research and policy in child and youth MH must address the consequences of the pandemic or comparable disruptions on adolescent MH, as well as mitigation strategies. An emphasis on integrated digital, community and school platforms for mental health within child and adolescent health services would benefit from a greater focus on early recognition and prevention.

Maternal separation affects Anxiety like behavior begin in adolescence continue through adulthood and related to Dnmt3a expression

Early life stress, including maternal separation, is among one of the main causes of anxiety in adolescents. DNA methyltransferase 3A (Dnmt3a) is a key molecule that regulates DNA methylation and is found to be associated with anxiety-like behavior. It is not clear whether maternal separation affects anxiety levels in mice at different developmental stages, or whether Dnmt3a plays a role in this process. Here, by using open field test to exploring the effect of maternal separation on anxiety-like behavior in mice of different age, it was found that maternal separation could successfully induce anxiety-like behavior in adolescent mice, and which continued through adulthood. By using western blot, we found the levels of Dnmt3a in the hippocampus and cortex have shown different trends in maternal separation mice on P17. Further, by using immunostaining, we have found that the expression levels of Dnmt3a in the cortex and hippocampus were significantly different, and decreased to varying degrees with the age of mice, which being the reason for different trends. Our results provide an experimental basis for further development of anxiety/depression treatment programs more suitable for adolescence.

The Effectiveness of Psychoeducational Interventions in Adolescents’ Anxiety: A Systematic Review Protocol

The COVID-19 pandemic had a strong impact on increasing anxiety in adolescents. This systematic review aims to identify the most effective psychoeducational interventions for reducing anxiety in adolescents following the guidelines of the Joanna Briggs Institute (JBI). The inclusion and exclusion criteria have been defined, and the search strategy has been planned. The search strategy will aim to locate both published and unpublished studies using, among other databases: CINAHL Plus with Full Text; PubMed; the Cochrane Central Register of Controlled Trials; and the JBI Database of Systematic Reviews. Following the search, all identified citations will be collated and uploaded into Endnote, and duplicates removed. Titles and abstracts will then be screened by two independent reviewers and by a third reviewer if a disagreement occurs. The results of the search will be reported in full in the final systematic review and presented in the PRISMA flow diagram. Eligible studies will be critically appraised for methodological quality using standardized critical appraisal instruments from the JBI. Data will be extracted from the studies included using the standardized JBI data extraction tool. For data synthesis, studies will be pooled using JBI SUMARI. The GRADE approach for grading the certainty of evidence will be followed, and a summary of findings will be created using GRADEPro GDT software. The results from this systematic review are expected to provide an overview of the most effective psychoeducational interventions for reducing anxiety in adolescents, allowing researchers to design and propose a new multicomponent psychoeducational intervention that will be validated and tested in the future.

Associations of 24-Hour Movement Behavior with Depressive Symptoms and Anxiety in Children: Cross-Sectional Findings from a Chinese Sample

This study examined the associations between adherence to 24-hour movement behavior guidelines (24-HMB) and the mental-health-related outcomes of depressive symptoms and anxiety in Chinese children. Data on movement behavior from 5357 children (4th and 5th grades), including physical activity, recreational screen time and sleep, were self-reported using the Health Behavior School-Aged Children Survey. Depressive symptoms and anxiety were self-reported using the Chinese version of the nine-item Patient Health Questionnaire and the Generalized Anxiety Disorder Scale, respectively. Depressive symptoms and anxiety were treated as categorical variables. Only 3.2% of the participants met physical activity, screen time, and sleep 24-HMB guidelines. Ordinal logistic regressions showed that, compared with participants who met the 24-HMB guidelines, participants who met none (odds ratio (OR) = 2.62, 95% CI: 1.76-3.90) or any one of the guidelines (OR = 1.88, 95% CI: 1.27-2.77) had higher odds of depressive symptoms. Similarly, there were higher odds of anxiety in participants who met none (OR = 2.32, 95% CI: 1.45-3.70) or any one of the recommendations (OR = 1.62, 95% CI: 1.03-2.57) compared with participants who met all the 24-HMB guidelines. Meeting the 24-HMB guidelines is associated with better mental-health-related outcomes in Chinese children. Because of the low prevalence of Chinese children meeting the 24-HMB recommendations, the present findings highlight the need to encourage children to regularly engage in physical activity, decrease their time spent sitting, and improve their sleep patterns.
