Democratic Support Survey Data for Measurement Invariance Analysis

Offering replication material for a study on scalar invariance violations in comparative democratic support data, conditionally accepted for a 2026 special issue of Public Opinion Quarterly. The data is associated with research on democratic mood and differential item functioning, particularly in a Latin American context.

Use Cases

• Analyze Differential Item Functioning in survey items related to Democratic Support across different contexts.
• Assess Measurement Invariance for comparative survey research on Democratic Mood.
• Apply Hierarchical IRT models to public opinion data to study cross-country comparability.

Strengths

• Data is linked to a peer-reviewed study conditionally accepted in Public Opinion Quarterly.
• The dataset is associated with research on a specific region (Latin America).
• Includes replication code (R scripts) for reproducing all figures and tables from the associated study.

Limitations

• The core dataset structure (rows, columns, sample data) is not described, limiting initial assessment.
• The data is primarily intended for replication, which may limit its utility for novel analysis without the original study context.
• The computationally intensive simulation components require specific R environment setup and may be time-consuming to re-run.
