Measuring authoritative teaching

High quality measurements are important to evaluate interventions. The study reports on the development of a measurement to investigate authoritative teaching understood as a two-dimensional construct of warmth and control. Through the application of confirmatory factor analysis (CFA) and structural equation modelling (SEM) the factor structure and measurement invariance is investigated. Generally, results suggest that the two-dimensional model of authoritative teaching has satisfactory psychometric properties for longitudinal measurement invariance, ensuring the measurement of the same concept over time. Different types of missing data in this study are discussed. Also, the relevance of such study for professional development is addressed.
