Targeted community-based programmes for children's mental health: A systematic review and meta-analysis of the Australian literature

The Effectiveness of Preventative Interventions to Reduce Mental Health Problems in at-risk Children and Young People: A Systematic Review of Reviews

Mental health problems are the leading cause of childhood disability worldwide, resulting in poor outcomes for children and young people that persist into adulthood. It is essential that those young people most at risk of developing mental health problems receive effective preventative interventions. Whilst there have been a number of systematic reviews which have examined the effectiveness of secondary prevention interventions for specific groups of children and young people, or to address identified mental health concerns, no review has engaged with the breadth of this literature. We conducted a systematic review of systematic reviews to map this complex field of secondary preventative interventions and identify effective interventions to prevent mental health problems in children and adolescents aged 3-17 years. The review protocol was registered on PROSPERO. We searched five electronic databases from inception to February 2023. The certainty of the evidence was appraised using the AMSTAR 2. We included 49 unique systematic reviews each including between 2 and 249 (mean 34) unique studies; the majority of which were reviews which included only or mostly randomised controlled trials (70%). The reviews examined selective interventions (defined as interventions which are delivered to sub-group populations of young people at increased risk of mental health problems) (n = 22), indicated interventions (defined as interventions which target young people who are found to have pre-clinical symptoms) (n = 15) or a synthesis of both (n = 12). The certainty of the evidence in the reviews was rated as high, (n = 12) moderate (n = 5), low (n = 9) and critically low (n = 23). We found evidence to support both selective and indicated interventions in a range of populations and settings, with most of this evidence available for children and young people in their mid-years (6-10 years) and early adolescence (11-13 years). There was a large body of evidence suggesting that resilience enhancing, cognitive behaviour therapy-based and psychoeducational interventions for children who experience adversity, or those with subclinical externalising problems may offer promise. Early selective interventions for a subpopulation of children and young people who have experienced adversity which combines risk reduction and resilience enhancing approaches directed at children and their families may be effective at reducing mental health problems.

Effectiveness of Community-Based Programs on Aggressive Behavior Among Children and Adolescents: A Systematic Review and Meta-Analysis

Adolescent aggressive behavior has increasingly become a central issue affecting the safety of both school campuses and the broader society. Despite the existence of numerous community interventions targeting this issue, there has been a paucity of efforts to consolidate the findings on the effectiveness of community-based programs in preventing aggressive behavior. This meta-analysis sought to address this gap by reviewing and assessing the impact of community-based initiatives on reducing adolescent aggression. A thorough search was carried out on 12 electronic databases: EBSCO, ERIC, PubMed, PsycINFO, MEDLINE, EMBASE, Scopus, Web of Science, ProQuest Dissertations and Theses, the China National Knowledge, Wanfang Databases, and China Science and Technology Journal Database. Sixteen studies were finalized, and meta-analyses were performed using a random effect model on RevMan v5.4 software developed by Cochrane. The analysis encompassed 16 published studies, involving a total of 2,585 participants. The key components of existing programs for aggression reduction included providing behavioral skills and training for adolescents, employing a problem-solving approach to address behavioral issues, offering psychological treatment, and emphasizing community supervision. The results indicate a significant positive effect of community-based interventions on aggression reduction (standardized mean difference = -0.26, 95% confidence intervals [-0.39, -0.13], Z = 3.84, p < .001). The subgroup analyses revealed that the intervention's effectiveness was moderated by the duration of the intervention, its theoretical foundation, and the sample size. This study furnishes empirical evidence supporting the enhancement of policies and practices to foster community engagement in mitigating aggressive behavior.

Interventions for Young Children's Mental Health: A Review of Reviews

To determine the efficacy of intervention programs for young children (4-9 years) with emerging mental health needs, we conducted a review of meta-analytic and systematic reviews of the intervention literature. Of 41,061 abstracts identified and 15,076 screened, 152 review articles met the inclusion criteria. We reviewed interventions across multiple disciplines targeting: (1) general mental health concerns; (2) internalizing symptoms; (3) externalizing symptoms; (4) anxiety; (5) depression; (6) trauma; (7) symptoms of attention-deficit/hyperactivity disorder; and (8) mental health concerns associated with autism spectrum disorder. Substantial evidence was found for the efficacy of behavioral and cognitive behavioral interventions for general mental health concerns, externalizing symptoms (generally, as well as ADHD, conduct, and other behavioral symptoms) and internalizing symptoms (generally, as well as anxiety) aged 4-9 years. Emerging evidence was identified for interventions targeting trauma symptoms, depression symptoms, and social, emotional and behavioral symptoms in autism spectrum disorder in children aged 4-9 years. Currently there is only limited emerging evidence regarding non-behavioral or non-cognitive behavioral interventions for programs targeting children ages 4-9 years where the aim is to deliver an evidence-based program to improve child social, emotional and/or behavioral functioning. Given the recent rises in mental health needs reported in children, targeted behavioral-and/or cognitive behavior therapy-based interventions should be made widely available to children (and their families) who experience elevated symptoms.
