Review: School-based interventions to improve mental health literacy and reduce mental health stigma - a systematic review.

BACKGROUND: The steadily increasing prevalence of mental disorders in children and adolescents presents itself as a public health challenge, especially given the health, social and economic burden of mental disorders. School-based interventions aimed at improving mental health literacy and reducing mental health stigma have the potential to prevent mental disorders and promote mental well-being, thus reducing the burden of mental disorders. This review identified and synthesised evidence on the effectiveness of school-based interventions designed to improve mental health literacy and reduce mental health stigma. METHODS: Electronic bibliographic databases including MEDLINE, Embase, PsycINFO, Education Resources Information Center (ERIC), Child Development and Adolescent Studies, British Education Index and Applied Social Sciences Index and Abstracts (ASSIA) were searched. Randomised controlled trials (RCTs) were included if they assessed the effectiveness or cost-effectiveness of school-based intervention aimed at improving mental health literacy and reducing mental health stigma for children and young people aged 4-18 years. Quality of studies was appraised using the EPHPP tool. A numerical summary and a narrative description of the findings in relation to the research questions were synthesised. This systematic review was registered with PROSPERO (CRD42020191265). RESULTS: We identified 21 studies describing 20 unique school-based mental health interventions. Overall, there is moderate evidence suggesting that school-based mental health interventions can be effective in improving mental health literacy and reducing mental health stigma defined as attitudes and beliefs regarding mental disorders. However, there is less evidence for their long-term effectiveness, as most studies did not include follow-ups. CONCLUSIONS: Despite exclusively including studies with randomised designs, intervention and methodological heterogeneity poses uncertainties to any conclusions made. Future research should focus on resolving methodological issues concerning how outcomes are assessed and include process evaluations to better inform the design of an intervention in term of its delivery and implementation.

Review: School-based mental health literacy interventions to promote help-seeking - a systematic review.

BACKGROUND: School-based mental health literacy interventions aim to prevent mental disorders and promote mental wellbeing through improving the knowledge and understanding of mental health, mental disorders, and reducing stigma. Evidence suggests that good mental health literacy helps young people recognise mental health difficulties in themselves and in others, and seek help for mental health problems. Improved help-seeking can allow for early intervention, which prevents the progression of mental disorders and ultimately reduces the burden of mental disorders. The aim of this review is to identify and synthesise evidence on the effectiveness of school-based mental health literacy interventions in improving help-seeking outcomes. METHODS: We searched MEDLINE, Embase, PsycINFO, ERIC, Child Development and Adolescent Studies, British Education Index and ASSIA (June 2020). Additional searches were conducted a year later to identify any new publications (June 2021). We included randomised controlled trials (RCTs) assessing the effectiveness or cost-effectiveness of school-based interventions to improve help-seeking outcomes for children and young people aged 4-18 years. Included studies were critically appraised. RESULTS: We identified 11 studies investigating help-seeking outcomes of school-based mental health literacy interventions including a total of 7066 participants from 66 secondary schools. Overall, there is no strong evidence for the effectiveness of school-based mental health literacy interventions in improving help-seeking outcomes, including general attitudes towards help-seeking, personal intentions to seek help, knowledge of when and how to seek help for mental disorders, confidence to seek help, and actual help-seeking behaviours. None of the studies investigated the cost-effectiveness of the interventions. CONCLUSION: The lack of standardised measures with established reliability and validity for help-seeking outcomes, and the incomprehensive consideration of the multi-faceted concepts of MH literacy and MH stigma have contributed to the scarcity of evidence for the effectiveness. Future research should focus on developing standardised measurement tools and including economic evaluations to understand pragmatic and financial aspects of school-based mental health literacy interventions.
