Aggressive/antisocial behaviors in children and youth may result in impairments in family, social, or academic functioning and lead to long‐term negative consequences for both the individual and society as a whole. The potential of healthy dietand nutritional supplements to reduce aggression and antisocial behavior is an active area of study in nutritional mental health sciences. The goal of this systematic review is to (1) investigate the effectiveness/efficacy of nutritional interventions(dietary manipulation, fortification or supplementation) in reducing excessive aggression, antisocial behaviors, and criminal offending in children/youth (systematic review and meta‐analysis); and (2) provide an overview of implementation barriers and facilitators regarding nutritional interventions in children/youth (qualitative/narrative synthesis). After consulting theCampbell Collaboration's methodological guidelines, a comprehensive search for published and unpublished papers on controlled intervention studies was performed (up to February 26, 2024) using both electronic databases (MEDLINE,Embase, Cochrane Library, APA PsycInfo, Scopus, and the Allied and Complementary Medicine Database) and otherresources (e.g., Google Scholar, reference list of included studies and other reviews, websites of public health agencies). Thisstudy focuses on children and youth (up to the age of 24) presenting with an above‐average level of aggression/antisocial behavior. In terms of the intervention, we considered both dietary manipulation and nutritional supplementation with aduration long enough (minimum of 1 week) that a significant change in the individual's nutritional status could be expected.We included studies with a controlled design if, for outcomes, they reported on (1) behavioral‐level violence/aggression toward others in real‐life (non‐simulated) settings, (2) antisocial behaviors, or (3) criminal offending. Initial screening,checking for eligibility criteria, data extraction from, and risk of bias assessment for each eligible study were conducted independently by two reviewers. To perform the meta‐analysis, data from each original report were standardized(transformed into Hedges' g) so that results across studies could be meaningfully combined and interpreted. Data con-versions, computation of pooled effect sizes, and estimation of publication bias were conducted using the Comprehensive Meta‐analysis software (Version 4). Altogether, 51 reports (describing 50 individual studies) met our inclusion criteria, and72 effect sizes were extracted from these reports. Nutritional interventions with a broad target (e.g., broad‐spectrummicronutrient supplementation or general improvement in diet quality) had the most consistent and largest interventionThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.© 2025 The Author(s).

The United States has one of the highest rates of correctional supervision among all nations in the world, reflecting the disproportionate incarceration of racial minorities and economically disadvantaged groups. Scholars have emphasized the role of structural factors and governmental policies in longterm shifts in crime and incarceration. However, much of the psychological research on crime and antisocial behaviors has not deeply considered this broader context, focusing mostly on individual and proximal environmental risk factors. This article presents a novel synthesis of large cross-disciplinary literatures that have not been previously integrated. After a brief summary of dominant themes in psychological research on the topic, we review the strong evidence, primarily from fields outside of psychology, for structural forces that explain pathways into criminal justice involvement, independent of individual-level explanations. A broader ecological framework is outlined to help unconfound individual and structural influences, with the hope of motivating policy change that is evidence-based and equitable.

The former Minister for Community Safety, Ash Regan MSP, asked the Scottish Community Safety Network (SCSN) and the Scottish Government to undertake a review of antisocial behaviour (ASB). This report presents the findings from work undertaken to gather views on the current approach to antisocial behaviour in Scotland. It is based on discussions with key stakeholders across Scotland including those who have experienced antisocial behaviour, frontline staff seeking to prevent and tackle antisocial behaviour and community and equality groups including those representing minority communities in Scotland. The discussions included people from both urban and rural settings across different areas of Scotland.

The findings do not amount to a definitive statement on what people feel needs to be done to change the way we view, prevent and address antisocial behaviour. However, they do provide a qualitative evidence base given the size and breadth of engagement. It is clear from these sessions that there are no quick fixes or easy solutions here. Therefore, we need to look at how we set the path to begin the journey and identify future work activity and milestones.

Overall, 25 engagement discussions involving close to 250 people, representing a wide range of interests (Annex B - methodology summary) were held by the Scottish Community Safety Network and the Scottish Government. We are indebted to all who shared their time and their expertise. This report reflects the views, opinions and experiences from those discussions, and additional written feedback received.

The Scottish Government and its partners believe that everyone has the right to be, and feel, safe in their community and homes. Embedding change which will have a positive sustainable impact, requires a process of innovating, evaluating and building on success. We can also learn from challenging issues and sharing best practice.

What has come across very clearly during this engagement, is that prevention is better than cure and that working collaboratively in partnership is essential to finding long term solutions to address antisocial behaviour and make all of our communities safer and more welcoming places to live.

We all have a role to play in preventing and tackling antisocial behaviour and hope that this report will be used as the starting point of a much broader and deeper discussion of these issues, leading to a long-term road map of how we can work collectively to prevent and address antisocial behaviour in effective ways.

We can, and should, come together to address the mutual problems we face in our communities, but we will achieve little if we approach this in a way that is not properly considered, including the potential for unintended consequences, and therefore we need to develop structures which we can work within to achieve change and incrementally build on approaches which are proven to be successful.

As such, two recommendations arise from our assessment of the qualitative evidence:

Recommendation one

That Scottish Ministers, and statutory, non-statutory and voluntary sector service providers and communities themselves recognise that our approach to preventing and tackling antisocial behaviour needs to be a long-term approach (that recognises societal changes and evolves) and that we need to make a commitment to a programme of activity which will provide a framework that will guide us in taking forward this agenda in alignment with other linked national policies.

Recommendation two

An independently chaired group of experts, potentially including statutory, non-statutory and voluntary service providers, community representatives and other key interests should be brought together to develop a long-term framework for addressing antisocial behaviour.

This should have a strong focus on steps that can be taken to prevent antisocial behaviour from occurring as well as considering the effectiveness of current approaches to tackling the antisocial behaviour which occurs.

The findings in this and other relevant, existing reports should form the foundations of the group’s work and they should not be restricted in identifying what areas are most important to move this agenda forward, which could include considerations of the effectiveness of current legislation.

The group should be able to commission and gather evidence to support their work and have a free hand to engage with anyone who can support this agenda. Central to this work should be building broad support for any long-term work that the group proposes.
