Japanese Epistemic Curiosity Scale: English Version for Cross-Cultural Comparison

Kazuji Nishikawa's 2026 study provides a 36.7 KB English translation of the Japanese Epistemic Curiosity (J-EC) scale. This document details the development and validation of the scale, which measures diversive and specific curiosity as personality traits. The work enables international comparisons of curiosity levels among Japanese populations.

Use Cases

• Validate the factor structure of diversive and specific curiosity based on the described translation and assessment process.
• Conduct cross-cultural comparisons of curiosity levels based on the stated goal of the English version's development.
• Assess the reliability and validity of curiosity subscales based on the reported results of factor and correlation analyses.
• Study the role of epistemic curiosity in learning and education based on the theoretical foundation mentioned in the description.

Strengths

• The scale is explicitly validated for factor structure, reliability, and validity as reported in the study.
• Dataset is shared under a permissive CC-BY-4.0 license, facilitating reuse and distribution.
• Author and last update date (2026-04-20) are clearly provided, supporting provenance.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The 36.7 KB file size suggests a very limited scope, likely containing the scale and documentation rather than a large dataset of responses.
• The primary file format is DOCX, which may require conversion for automated data analysis.
