Jean-Louis Monestès is a Professor of Clinical Psychology at the University of Grenoble Alpes, specializing in psychopathology and contextual behavioral science. His work primarily focuses on Acceptance and Commitment Therapy (ACT), Relational Frame Theory, and functional approaches to psychological disorders. He maintains an active research program examining rule-governed behaviors, psychological flexibility, and selectionist approaches to understanding mental health conditions. Dr. Monestès completed his doctoral studies at Université Charles de Gaulle Lille 3, where he earned his PhD in 2011 with research on "Liens entre attention centrée sur soi et évitement expérientiel dans les troubles anxio-dépressifs et leur prise en charge psychothérapeutique" (Links between self-focused attention and experiential avoidance in anxiety-depressive disorders and their psychotherapeutic management). He subsequently obtained his Habilitation à Diriger des Recherches (HDR) in 2012 with the work "Les réactions d'un sujet à ses expériences psychologiques: Vers une approche fonctionnelle globale" (A subject's reactions to their psychological experiences: Toward a global functional approach). Monestès' research interests center around contextual behavioral science, with particular emphasis on Acceptance and Commitment Therapy (ACT) , Relational Frame Theory (RFT) , and selectionist approaches to psychopathology . His work explores psychological flexibility as a transdiagnostic process, examining how rule-governed behaviors contribute to psychological suffering across various disorders. He has made significant contributions to understanding experiential avoidance in European cultural contexts and has developed French translations of key ACT assessment instruments. His research spans clinical populations including schizophrenia, chronic pain patients, and anxiety disorders, with a consistent focus on functional analysis of behavior rather than symptom-based approaches. Analysis of Monestès' recent publications reveals a strong trend toward cross-cultural validation of ACT measures, particularly in European contexts. His work demonstrates growing interest in organizational applications of psychological flexibility, extending ACT principles beyond traditional clinical settings into leadership development and workplace psychology. A substantial portion of his research focuses on schizophrenia spectrum disorders, examining cognitive processes like rule-governed behavior and perspective-taking. His publications also show consistent development of French-language assessment tools for ACT processes, contributing significantly to the internationalization of contextual behavioral science. Dr. Monestès has authored or co-authored numerous scientific publications including over 40 peer-reviewed articles, 8 books, and 17 book chapters. His books include "ACT – La thérapie d'acceptation et d'engagement en pratique" (2017), "L'approche transdiagnostique en psychopathologie" (2016), and "La thérapie d'acceptation et d'engagement" (2011). He has presented his research at numerous international conferences including the World-Conference of the Association for Behavioral and Contextual Science. Monestès maintains active research collaborations, particularly with colleagues like Matthieu Villatte, Gwénaël Loas, and others across European institutions. His work bridges clinical practice with basic behavioral research, consistently emphasizing functional contextual approaches to understanding and treating psychological disorders. He has contributed significantly to the French-speaking contextual behavioral science community through translations, adaptations of assessment tools, and theoretical developments tailored to European cultural contexts.
