Self-Determination Theory
A theory of motivation by Edward Deci and Richard Ryan stating that people are most intrinsically motivated when three basic psychological needs are met: autonomy, competence and relatedness. It is one of the most thoroughly researched motivation theories and explains why control and pressure tend to undermine engagement.
When to use Self-Determination Theory
When motivation or engagement is a concern, for example mandatory training, long programmes, or sessions meant to change habits.
How Self-Determination Theory works
Activities provide autonomy, build competence, and foster relatedness.
Phases of Self-Determination Theory
- Autonomy: People need to feel they act by choice. In a session: explain the why, offer meaningful options and avoid controlling language.
- Competence: People need to feel effective. In a session: pitch challenges at the right level, give clear structure and informative feedback.
- Relatedness: People need to feel connected and respected. In a session: create belonging through pair work, names and genuine interest in contributions.
Key principles
- Autonomy support over control
- Optimal challenge with feedback
- Belonging supports motivation
- Intrinsic motivation outlasts rewards
Best for
- Mandatory or compliance training
- Long programmes and cohorts
- Coaching and behaviour change
- Designing for voluntary participation
Considerations
- Autonomy does not mean no structure; learners still need clear guidance.
- External rewards and heavy monitoring can undermine the intrinsic motivation you want to build.
- Cultural context shapes how autonomy and relatedness are experienced.
