Mokken Scale Analysis
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Mokken-scale analysis is a non-parametric item response theory (IRT) method used in psychometrics to examine the scalability and hierarchical structure of questionnaire items. It helps determine whether items form a unidimensional scale and assess their ordering and reliability, facilitating the development of valid measurement instruments.
Key Features
- Non-parametric approach to item response modeling
- Assess scalability and hierarchical structure of items
- Used for validating questionnaires and scales
- Provides Loevinger's H coefficient to measure scale strength
- Applicable to ordinal data and Likert-type responses
- Identifies homogeneous item groups forming a reliable scale
Pros
- Provides a robust framework for scale validation using non-parametric methods
- Useful for examining the hierarchical ordering of items
- Relatively simple to implement compared to parametric IRT models
- Supports assessment of scale reliability and consistency
- Flexible with different types of ordinal data
Cons
- Less detailed modeling capabilities compared to parametric IRT models
- Requires large sample sizes for stable results
- Interpretation can be complex for inexperienced users
- Limited in handling multidimensional constructs without adaptations
