About
Professor Nicolas ROUSSIAU is a distinguished faculty member at the University of Nantes' Faculty of Psychology, where he leads research through the Psychology Laboratory of Pays de la Loire (UR 4638). His academic profile integrates empirical rigor with philosophical depth, focusing on the psychological dimensions of spirituality across health, social, and methodological domains.
His research program centers on three interconnected pillars:
- Spirituality, Religion and Health: Investigating how spiritual beliefs influence health behaviors and outcomes, including studies on homeopathy efficacy perceptions and workplace spirituality-health connections
- Social Judgment and Representations: Analyzing cognitive frameworks for understanding social phenomena, with emphasis on self-esteem mechanisms and temporal comparison processes
- Methodological Innovation: Specializing in cross-culturally validated psychometric scales for measuring spirituality, including French adaptations of international instruments
Professor Roussiau's publication trajectory (2020-2024) reveals consistent output in high-impact journals, characterized by international collaboration (15+ countries), theoretical innovation in 'implicit spirituality,' and methodological precision in scale validation. His work increasingly bridges positive psychology with spiritual dimensions, as evidenced by the 2023 Frontiers in Psychology special issue he guest-edited.
Through the Psychology Laboratory of Pays de la Loire, he maintains active research programs that attract international collaborators. His editorial leadership—including the 2021 co-edited volume 'Psychology and Spirituality: Foundations, Concepts and Applications'—demonstrates his role in shaping scholarly discourse. Current projects emphasize cross-cultural comparisons of religiousness dimensions and the development of assessment tools for clinical and organizational settings.
