VHAS: PTSD Symptom Clusters by Trauma Exposure in Older Vietnamese Adults

The Vietnam Health and Aging Study (VHAS) second wave (2021–2022) provides aggregated summary data on PTSD symptom severity in community-dwelling Vietnamese adults aged 60 and older. The dataset includes summary statistics, frequencies, and logistic regression results from the PTSD Checklist for DSM-5 (PCL-5). It was authored by Le Xuan Hung and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Comparing PTSD symptom cluster profiles based on direct versus indirect trauma exposure modalities described in the study.
• Verifying reported descriptive statistics like mean and standard deviation of total and cluster-level PCL-5 scores.
• Replicating logistic regression analyses using the provided odds ratios and confidence intervals.
• Examining the proportion of a clinical population meeting the PTSD threshold (PCL-5 ≥11) in an older adult cohort.

Strengths

• Data is derived from a defined population-based cohort (VHAS) with a specific time range (2021–2022).
• Includes multiple analytical outputs: summary statistics, frequencies, and logistic regression results.
• Explicitly protects participant confidentiality by providing only aggregated summary-level data.
• Supports verification of findings from a specific, peer-reviewed study.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (6.9 KB), indicating limited scope and aggregated, non-individual-level data.
