Professor Yasuo Miyazaki is interested in developing a new statistical and measurement modeling methodology and/or improving current methodology for the most pressing issues that plague behavioral and social scientists to answer the important questions. Miyazaki considers one of the most pressing problems in behavioral and social sciences to lie in the measurement of key variables in research since many of them are phrased in abstract terms such as ability, anxiety, social skills, and school climate, as they cannot be directly observed.  

Since human development through formal education occurs in school contexts, it is also important to consider the validity and reliability of measurements at teacher and school level as well as the individual level constructs. Because of the hierarchical nature of educational settings, Miyazaki has been focusing on the methodology and applications surrounding Hierarchical Linear/Nonlinear Modeling (also known as Multilevel Modeling), a useful methodology for studying phenomena that occur in multilevel contexts.

Hierarchical Linear/Nonlinear Modeling shares a common theme with other major methodologies used in behavioral and social sciences, such as structural equation modeling and Item Response Theory. The common theme he has found is the use of latent variables. Thus he is making efforts to combine and integrate Hierarchical Linear/Nonlinear Modeling with the structural equation modeling and Item Response Theory to develop new and improved methodology and applications.

Miyazaki is currently tackling several specific topics:

  • A longitudinal growth model from item level data;
  • Measurement model to capture the organizational climate;
  • Contextual/compositional effects in organizational research; and
  • Impacts of nested data structure on Item Response Theory model parameters.
  • Multilevel Modeling
  • Growth Modeling / Longitudinal Data Analysis
  • Reliability and Meta-analysis Model for Reliability Coefficients
  • Multilevel Measurement Model
  • Multilevel Factor Model
