Self-Determination Theory (SDT) is a theory of motivation. It is concerned with supporting our natural or intrinsic tendencies to behave in effective and healthy ways. SDT has been researched and practiced by a network of researchers around the world.

The theory was initially developed by Edward L. Deci and Richard M. Ryan, and has been elaborated and refined by scholars from many countries. Deci is currently a professor at the University of Rochester in the Department of Clinical and Social Sciences in Psychology in Rochester, NY; Ryan, a clinical psychologist, was recently appointed as Professor at the Institute for Positive Psychology and Education at the Australian Catholic University in Sydney, Australia.  Together and separately Deci and Ryan have promoted SDT through theory, research, and their ongoing training of scholars.

This website presents a brief overview of SDT and provides resources that address important issues such as human needs, values, intrinsic motivation, development, motivation across cultures, individual differences, and psychological well-being. Also addressed are the applications of Self-Determination Theory to:

  • Education
  • Healthcare
  • Relationships
  • Psychotherapy
  • Psychopathology
  • Organizations
  • Sports and Exercise
  • Goals
  • Health and Well-being
