  • Synthesizing measurement sciences, predictive analytics, evidence-based medicine/practice, and informatics to guide clinical decision making in real time and to improve symptom and disease management over time.
  • Smart learning and testing to improve clinical competencies

Research Interests

  • Ability and competency assessment
  • Patient-reported outcomes (PROs) and health-related quality of life (HRQOL)
  • Item response theory (IRT) and computerized adaptive testing (CAT)
  • Smart testing and learning (STL) – dynamic assessment and tailored education
  • Precision Rehabilitation Outcomes Universal Design (PROUD)

Teaching Roles

Dr. Chang teaches Measurement Theory and Development (OT680.01).


1987: BS in Psychology, National Chengchi University, Taipei, Taiwan
1995: PhD in Research Methodology and Quantitative Psychology, University of Chicago, Chicago, Illinois


Dr. Chang is a psychometrician and health services researcher trained in research methodology and quantitative psychology. His research focuses on the integration of methodology and technology to advance clinical outcomes assessment and management across the continuum of care. Dr. Chang has extensive experience and expertise in patient-centered outcomes measurement and management in diverse populations and settings utilizing item response theory (IRT) and computerized adaptive testing (CAT). He has created a discipline called "Clinical Infometrics" that is a synthesis of measurement sciences, predictive analytics, evidence-based medicine and informatics to guide clinical decision making in real time and to improve symptom and disease management over time. Dr. Chang directs the Psychometrics-Informatics Laboratory (The pi Lab), which aims to integrate advanced psychometrics and evolving informatics to advance our understanding of participation and human health. The pi Lab focuses on the knowledge translation of measurement theory and data science methods to clinical applications.
