In addition to formal theory development, research has applied SDT in many domains including education, organizations, sport and physical activity, religion, health and medicine, parenting, virtual environments and media, close relationships, and psychotherapy. Across these domains, research has looked at how controlling versus autonomy-supportive environments impact functioning and wellness, as well as performance and persistence. In addition, supports for relatedness and competence are seen as interactive with volitional supports in fostering engagement and value within specific settings, and within domains of activity. This body of applied research has led to considerable specification of techniques, including goal structures and ways of communicating that have proven effective at promoting maintained, volitional motivation.
The varied articles on this website demonstrate the many types of inquiry associated with the SDT framework, as well as its generative capacity with respect to practical issues in human organizations of all kinds. Relevant research reports and theoretical discussion are listed in the Publications section, organized by topic.
By focusing on the fundamental psychological tendencies toward intrinsic motivation and integration, SDT occupies a unique position in psychology, as it addresses not only the central questions of why people do what they do, but also the costs and benefits of various ways of socially regulating or promoting behavior. Overviews of the theory can be found in Ryan and Deci (2000) and in Deci and Ryan (1985, 2000), as well as numerous other articles and chapters identified on this website.
