DataSheet1_The Impact of Place-Based Approaches Addressing Mental Health and Substance Use Among Adolescents: A Systematic Review of the Literature.docx

ObjectivesWe systematically appraised peer reviewed evidence assessing the impact of “place-based approaches” (PBAs) – those requiring multi-sectoral action within localities to address complex health challenges – on mental health outcomes among adolescents.
MethodsWe searched six databases from inception to May 2023. We defined PBAs as at least two sectors (e.g., local government, health) working collaboratively within a locality. Studies reporting mental health and substance-use among young people (aged 10–24) were included. Two authors independently assessed study quality using MMAT. Heterogeneity in PBAs, study design and outcomes prevented meta-analysis; results were narratively synthesised.
ResultsThirty-three publications presented data from 22 PBA evaluations; 6 evaluations assessed mental health or wellbeing, 16 appraised substance use. Higher quality evaluations found no impact on mental health outcomes (n = 4), and some evidence for delayed initiation (n = 4) and reduced point-in-time use (n = 10) of alcohol. Evidence for impact on binge-drinking and drug use was mixed.
ConclusionBased on very few published studies of mixed quality, PBAs have not improved mental health or wellbeing among adolescents. More evidence exists to suggest PBAs can improve certain alcohol use outcomes in young people.

研究目标：我们系统评估了同行评议的相关证据，以考察“基于场所的干预措施（place-based approaches，PBAs）”——即要求在地方层面开展多部门协作以应对复杂健康挑战的干预模式——对青少年心理健康结局的影响。
研究方法：本研究从各数据库建库起始至2023年5月，共检索了6个学术数据库。我们将基于场所的干预措施界定为：至少两个部门（如地方政府、医疗卫生机构）在特定地域内开展协同合作的干预模式。纳入研究需报告10~24岁青少年群体的心理健康与物质使用相关结局。由两名研究者独立采用MMAT量表对纳入研究的质量进行评估。由于基于场所的干预措施类型、研究设计及结局指标均存在显著异质性，无法开展Meta分析，最终研究结果采用叙述性综合法进行整合。
研究结果：共33篇文献报告了22项基于场所的干预措施评估数据；其中6项评估聚焦青少年心理健康或福祉状况，16项评估考察了物质使用情况。高质量评估未发现该类干预对青少年心理健康结局存在显著影响（n=4），同时有部分证据表明，此类措施可延缓青少年初次饮酒的年龄（n=4）、降低即时饮酒发生率（n=10）。关于其对暴饮与药物使用的影响，现有研究证据结果不一。
研究结论：基于数量极少且质量参差不齐的已发表研究，基于场所的干预措施未能改善青少年的心理健康或福祉水平。现有更多证据提示，此类干预可改善青少年的部分饮酒相关结局。
