背景和目的在先前关于社区特征对心理健康影响的研究中，通常使用参与者评估的社区暴露，这可能导致同源偏差，因为个人的心理健康状况可能影响他们对社区的判断。为了避免这种潜在的偏差，我们评估了单独评估社区暴露的使用情况，以了解它们与集体评估措施的比较（通过汇总同一社区内的多个反应）。这将通过将邻里测量与个人心理健康状况脱钩来提高测量的有效性。我们对加拿大多伦多87个人口普查区（每个人口普查区平均28人）的2411名成年人进行了分层随机调查，以调查自我报告（单独评估）的社会环境邻里措施与汇总、集体评估的邻里问题/混乱、安全、服务质量、联系、纽带和桥接社会资本措施的对比。结果，过去12个月的重度抑郁经历，是用综合国际诊断研究抑郁量表短表来衡量的。结果：(1)单独评估的邻里问题，(2)低（单独评估的）邻里安全，(3)低（单独评估的）邻里服务质量，以及(4)低（单独评估的）连接社会资本与抑郁症独立相关(均至少p
Background and purpose It is common in prior studies of the influence of neighbourhood characteristics on mental health to use participant-assessed neighbourhood exposures, which can lead to same-source bias since an individual's mental health status may influence their judgement of their neighbourhood. To avoid this potential bias, we evaluated the use of individually assessed neighbourhood exposures to understand how they compare to collectively assessed measures (by aggregating multiple responses within the same neighbourhood). This would increase the validity of the measure by decoupling the neighbourhood measure from an individual's mental health status.Methods We conducted a stratified-randomised survey of 2411 adults across 87 census tracts in Toronto, Canada (mean of 28 per census tract) to investigate how self-reported (individually assessed) social environmental neighbourhood measures compared to aggregated, collectively assessed, measures for neighbourhood problems/disorder, safety, service quality, and linking, bonding and bridging social capital. The outcome, experience of major depression in the past 12 months, was measured using the Composite International Diagnostic Studies Depression Scale Short Form.Results (1) Individually assessed neighbourhood problems, (2) low (individually assessed) neighbourhood safety, (3) low (individually assessed) neighbourhood service quality, and (4) low (individually assessed) linking social capital were independently associated with depression (all at least p
