Self-determination refers to the ability of individuals to make choices and decisions about their own lives, based on their own values and preferences. This research area examines how people's sense of autonomy and control over their own actions and behavior influences their motivation, well-being, and overall satisfaction with their lives. Researchers in this field explore the psychological, social, and cultural factors that contribute to individuals' sense of self-determination, and how it relates to their personal growth, happiness, and fulfillment. Studies may also focus on interventions and strategies to support and enhance self-determination in various settings, such as schools, workplaces, and healthcare settings.
