The UK private rental housing market has poorer quality housing compared with other sectors and is subjected to calls for better regulation. Poor quality housing poses risks to mental and physical health, and housing improvement can potentially benefit health and well-being. Local authorities have powers to implement selective licencing (SL) schemes in specific localities. Such schemes involve landlord registration, payment of licence fees, local authority inspection and requirements that landlords conduct any necessary renovation works to ensure housing standards are met. We aim to evaluate SL in Greater London and to test the feasibility of a national evaluation.
We will measure individual-level and area-level impacts of SL in Greater London between 2011 and 2019. A difference-in-differences approach with propensity score-matched controls will be used. We propose to exploit data from the Annual Population Survey (APS) and health and social benefit registers to measure mental health and well-being at individual (self-reported anxiety) and area (Small Area Mental Health Index) level. We estimate 633 APS participants in our intervention groups compared with 1899 participants in control areas (1:3 ratio of intervention to control). Secondary outcomes will be self-reported well-being and residential stability at the individual level and incidence of police-recorded antisocial behaviour calls and population turnover at the area level. The study size of the area-level analyses will be 3684 lower layer super output areas (including controls). Qualitative semistructured interviews with lead implementers in several London boroughs will produce insights into variations and commonalities between schemes.
Ethical approval was obtained from London School of Hygiene and Tropical Medicine's Ethics Committee (reference number 26481) and London Borough of Hackney. All interviewees will be asked for informed written consent. Study findings will be published in a peer-reviewed journal.
与其他领域相比，英国私人租赁住房市场的住房质量较差，因此需要更好的监管。住房质量差会对身心健康造成风险，而改善住房条件则有可能有益于健康和幸福感。地方当局有权在特定地区实施有选择的许可（SL）计划。此类计划涉及房东登记、支付许可费、地方当局检查以及要求房东进行任何必要的翻新工作，以确保达到住房标准。我们旨在评估大伦敦的 SL，并测试全国性评估的可行性。
我们将在 2011 年至 2019 年期间测量大伦敦 SL 的个体和区域层面的影响。将采用倾向评分匹配对照的差异中的差异方法。我们建议利用年度人口调查（APS）和健康与社会福利登记数据来衡量个体（自我报告的焦虑）和区域（小区域心理健康指数）层面的心理健康和幸福感。我们估计干预组有 633 名 APS 参与者，而对照组有 1899 名参与者（干预组与对照组的比例为 1:3）。次要结果将是个体层面的自我报告幸福感和居住稳定性以及区域层面的警察记录的反社会行为电话发生率和人口周转率。区域层面分析的研究规模将为 3684 个较低层超级输出区（包括对照组）。对伦敦几个行政区的主要实施者进行半结构化定性访谈，将深入了解计划之间的差异和共性。
伦 敦卫生与热带医学学院伦理委员会（参考编号 26481）和伦敦哈克尼行政区已批准本研究的伦理。所有受访者都将被要求书面知情同意。研究结果将在同行评审的期刊上发表。
