Smartwatch vs Self-Reported Sleep Data from 130 Participants

A validation dataset comparing smartwatch-measured and self-reported sleep parameters from 130 participants over 841 sleep instances. The data was collected between November 2023 and June 2024 from participants wearing three generations of Garmin smartwatches. It was authored by Christina T. Saliba and shared under a CC-BY-4.0 license.

Use Cases

• Validate sleep duration algorithms for wearables based on the comparison of smartwatch-recorded and participant-reported timestamps.
• Assess the correlation between device-derived sleep scores and self-reported Sleep Quality Scale (SQS) scores.
• Analyze discrepancies in sleep measurement accuracy across different smartwatch models (Garmin Vívoactive 4, Venu 2 Plus, Venu 3/3S).
• Investigate sleep duration reporting differences in specific populations, such as healthcare shift workers, as mentioned in the exploratory analyses.

Strengths

• Includes 841 sleep instances from 130 participants, providing a basis for statistical analysis.
• Compares three specific smartwatch models (Garmin Vívoactive 4 2019, Venu 2 Plus 2022, Venu 3/3S 2023), allowing for generational analysis.
• Data collection spanned a defined period from November 7, 2023, to June 30, 2024.
• Employs multiple statistical methods (paired t-tests, equipercentile linking, chi-square tests) as described in the study.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is small (132.2 KB), suggesting limited scope or that the primary data may be summarized results within a document.
• The primary file is a DOCX document, which may require extraction or conversion to access structured data.
