نظرية التحديد الذاتي لريان وديشي

Self-determination theory identifies autonomy, competence, and relatedness as three fundamental psychological needs essential for personal growth and well-being. Autonomy is the desire to control one's actions and decisions aligned with personal values. Competence refers to feeling capable when overcoming challenges. Relatedness involves establishing meaningful connections with others. When satisfied, these needs foster intrinsic motivation and optimal functioning.

Autonomy fosters intrinsic motivation because individuals feel they act from personal choice rather than external pressure. Students who choose their own projects tend to be more motivated and engaged than those assigned tasks. This sense of control aligns actions with personal values and interests, enhancing both motivation and satisfaction with learning activities.

Competence refers to feeling capable and effective when successfully overcoming challenges. A baseball player may feel motivated to practice more when observing improved batting accuracy, as mastery reinforces confidence. When people feel competent, they are more likely to take on new challenges and invest in tasks that promote growth and skill development.

Relatedness involves the need to establish meaningful relationships and connections with others. Employees often feel more motivated and satisfied in jobs where they experience strong teamwork and colleague support. This sense of belonging enhances emotional well-being and fosters collaboration, making relatedness essential for overall job satisfaction and performance.

When autonomy, competence, and relatedness needs are unmet, individuals may shift toward extrinsic motivation, focusing on external rewards like money or approval rather than inherent satisfaction. This contrasts with intrinsic motivation, which flourishes when all three needs are satisfied. Unmet needs reduce personal growth and overall well-being.

Intrinsic motivation involves engaging in activities for their inherent satisfaction, while extrinsic motivation focuses on external rewards like money or approval. Self-determination theory shows that intrinsic motivation flourishes when autonomy, competence, and relatedness needs are met. Athletes driven by these needs perform better and enjoy their sport more than those solely motivated by external rewards.

Research has demonstrated the universality of self-determination theory across cultures. People who satisfy their needs for autonomy, competence, and relatedness report higher levels of happiness, personal growth, and well-being regardless of cultural background. This cross-cultural evidence supports SDT as a fundamental framework for understanding human motivation and psychological health.
