<p>Bivariate Correlations among Study Variables.</p>

2,240 adults aged 65 or older from the National Social Life, Health, and Aging Project provide data on perceived neighborhood danger, insomnia, and depressive symptoms. Seo-Yun Choi's analysis, published on figshare in 2026, identifies insomnia as a mediator, accounting for 25.8% of the total effect of neighborhood danger on depression. The 9.5 KB XLS file contains bivariate correlations supporting this psychological pathway.

Use Cases

• Replicate mediation analysis based on the reported bivariate correlations and bootstrap results.
• Study the relationship between environmental stressors and mental health in older adults based on the described variables.
• Investigate sleep as a mediator between perceived safety and depression based on the conceptual model.
• Benchmark sociological models using a dataset with controlled sociodemographic and health covariates.

Strengths

• Data originates from a named national study, the National Social Life, Health, and Aging Project (NSHAP) Wave 3.
• Analysis is based on a specific sample size of 2,240 adults aged 65 or older.
• Results include a quantified indirect effect (B=.04) and a specific proportion of the total effect explained (25.8%).
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 9.5 KB file size indicates a very small, likely summary-level dataset, not the raw survey data.
