Spanish-Language EPO-1 Well-Being Survey Data from Argentina and Ecuador

A cross-sectional sample of 627 people and a longitudinal sample of 135 participants from Argentina and Ecuador completed the Emotional and Psychological Outcome – Item 1 (EPO-1) well-being tool alongside other psychological measures. The dataset, authored by Rocio Manubens and hosted on Harvard Dataverse, was last updated in July 2026. It examines the psychometric properties and scoring format preferences of the Spanish-language EPO-1.

Use Cases

• Compare psychometric performance of Likert vs. Visual Analogue Scale (VAS) scoring formats based on the described validation study.
• Analyze cultural differences in well-being measurement based on data from Argentina and Ecuador.
• Assess criterion validity of a single-item well-being measure against established tools like CORE-10, PHQ-2, and GAD-2.
• Evaluate test-retest reliability and sensitivity to change in a brief assessment tool.
• Study user preferences for survey response formats in community settings.

Strengths

• Includes data from 627 participants in a cross-sectional study and 135 in a longitudinal study over seven days.
• Compares three distinct survey formats: Likert-only, VAS-only, and a combination format.
• Validates against multiple established psychological measures (CORE-10, PHQ-2, GAD-2, SWLI, MII, PCII).
• Provides psychometric analysis across two distinct cultural contexts (Argentina and Ecuador).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the full dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic and cultural bias inherent to the specific community samples from Argentina and Ecuador.
