School‐based mindfulness intervention for depressive symptoms in adolescence: For whom is it most effective?

Effects of mind-body therapies on depression among adolescents: a systematic review and network meta-analysis

Background

Depression poses significant threats to adolescents' health globally. Research has shown the potential of mind-body therapies to alleviate depression, but limited studies have directly compared the therapeutic effects of different types of mind-body therapies on adolescent depression and the optimal therapy remain unclear. Therefore, we conducted a systematic review and network meta-analysis of randomized controlled trials that met the inclusion criteria to explore the effectiveness of different types of mind-body therapies as interventions to improve depression among adolescents, and to identify the most effective interventions.

Methods

A comprehensive search of databases including PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus up to January 2024 was conducted to assess the impact of mind-body therapies on depression among adolescents. The risk of bias of the included studies was evaluated using Cochrane Review Manager 5.4. STATA 18.0 was used for network meta-analysis. The node-splitting method was used to test the local inconsistency of the network meta-analysis. Funnel plots and the Egger's test were utilized to assess the potential impact of bias in this study.

Result

This network meta-analysis included 9 randomized controlled trials involving a total of 955 subjects. The results indicated that yoga, dance therapy and Tai Chi were more effective than other mind-body therapies in reducing symptoms of depression among adolescents. Specifically, according to the SUCRA ranking, yoga was rated to be the optimal intervention for adolescents with depression (SCURA: 82.2%), followed by dance therapy (SCURA: 77.5%) and Tai Chi (SCURA: 64.9%).

Conclusion

This study revealed that mind-body therapies have positive effects on improving depression among adolescents. Yoga may be the most effective intervention among the different types of mind-body therapies. However, due to the small sample size of patients included, the certainty of the results was limited to some extent. Therefore, further investigation is necessary to strengthen the evidence base when more relevant studies become available.

School-based interventions to improve emotional regulation skills in adolescent students: A systematic review

INTRODUCTION

Emotional regulation (ER) is a core variable involved in the onset and maintenance of mental health disorders; therefore, interventions targeting ER in adolescence represent a promising preventive action. The current systematic review provides a synthesis of the evidence on school-based interventions on ER in adolescent students.

METHODS

Six electronic databases (Medline, Psychology Database, Embase, Scopus, Psychinfo, and Web of Science) were searched. The methodological quality of the included studies was assessed by the Methodological Index for Nonrandomized Studies.

RESULTS

A total of 36 studies were identified. The interventions were based on different theoretic frameworks and focused on different components of ER. There were universal interventions that addressed the entire class, as well as interventions for a selected population of at-risk students. Only one-third of the studies were based on manualized programs. Small to moderate effect sizes were found for mental health and ER skills. Only a few studies assessed risky behaviors, and these studies showed a reduction with moderate to large effect size. Studies conducted on high-risk populations showed medium-high effect sizes on ER skills. In contrast, studies conducted on unselected samples of students showed greater variability in the outcome estimates. Acceptability analysis and attendance rates suggested that the interventions were well received by students. The lack of follow-up assessments and the absence of sample-size calculation were the most frequent methodological weaknesses.

CONCLUSIONS

The content of the present review could be useful for professionals involved in the planning of school psychological services. Overall, the findings of the current review support the applicability and beneficial effect of school-based intervention for adolescents. Moreover, the results clearly point out the utility of a multitiered model to structure coordinated and integrated preventive interventions and to optimize resources.
