What problem does it solve?
This Skill solves the problem of building and validating social science measurement instruments so that your scales are reliable, valid, and comparable across groups.
Core Features & Use Cases
- Reliability & internal consistency: Compute Cronbach’s alpha and interpret it alongside omega-based reliability (including omega hierarchical) and item-total diagnostics.
- Factor structure validation: Run EFA and CFA to estimate dimensionality and test hypothesized measurement models.
- Advanced measurement validation: Perform measurement invariance testing across groups, fit bifactor models, and (when appropriate) apply IRT and network psychometrics for deeper scale evaluation.
- Scale scoring: Construct composite indices (simple, weighted, or standardized) based on your indicators and chosen measurement model.
Quick Start
Use this skill to validate a Likert-scale by running EFA then CFA, reporting reliability (alpha/omega), and testing measurement invariance across two groups.
