Stefan Stieger

Stefan Stieger is a Professor and Head of the Department of Psychological Methodology at the Karl Landsteiner Private University of Health Sciences. He leads an interdisciplinary research team focused on advancing psychological methodology through the integration of technology, statistics, and software development. His work bridges psychology and informatics, particularly in the emerging field of psychoinformatics.

His research interests include psychometrics, individual differences, self-esteem, personality (e.g., Big Five, Dark Triad), life satisfaction, and digital well-being. He emphasizes methodological innovation, particularly through Experience Sampling Methods (ESM) and the development of open-source tools like ESMira, which enables real-time data collection in natural environments. His work often involves large-scale, cross-cultural studies and replication research to ensure robust psychological science.

Recent publications highlight trends in replication studies, cross-cultural invariance of psychological scales, mood and energy dynamics, social perception, and the role of technology in behavioral research. His articles frequently appear in high-impact journals and address both foundational methodological questions and applied topics such as mental health in crisis regions.

Stefan Stieger is actively involved in funded research projects, including studies on CO₂ and cognitive performance, app-based workplace health interventions, demographic diversity in groups, sexual activity frequency, and peer support for diabetes management. He collaborates extensively with international researchers and institutions.

He advises and mentors students and junior researchers, though specific names are not listed. His team develops software solutions for the scientific community, promoting open science and reproducibility.
