Our
Institute
We are an international non-profit initiative dedicated to advancing and connecting brief psychological and counseling approaches worldwide.
Founded in Athens, Greece and operating globally, IISTP builds bridges between professionals, institutions, and research communities.
At A Glance
We believe that the evolution of psychotherapy must move in synchrony with the speed and complexity of our time. For this reason, IISTP documents and brings together short-term psychological approaches and techniques within a structured, objective, and scientifically grounded international registry.
Our work is guided by academic integrity, methodological clarity, and professional rigor. We record established brief approaches while remaining open to innovation, allowing emerging models and new ideas to be presented, examined, and supported when evidence and relevance justify their inclusion.
Through international collaboration, we expand partnerships and map contemporary developments in brief psychology worldwide. Our registry enables professionals to understand new trends and identify the institutions and organizations representing them at a global level.
