What is satisfying about satisfying events? Testing 10 candidate psychological needs

Area of Science:

• Psychology
• Human Needs Research
• Social Psychology

Background:

• Understanding fundamental human psychological needs is crucial for well-being.
• Previous theories proposed various needs, but empirical validation of their core importance is ongoing.
• Self-determination theory highlights autonomy, competence, and relatedness as key psychological needs.

Purpose of the Study:

• To empirically identify and rank the most fundamental psychological needs for human beings.
• To compare the salience and impact of ten candidate psychological needs across different contexts.
• To investigate the role of psychological needs in both satisfying and unsatisfying life events.

Main Methods:

• Three studies were conducted, involving participants describing "most satisfying events" in their lives.
• Participants rated the salience of ten candidate psychological needs within these described events.
• A cross-cultural component included U.S. and South Korean samples, and analyses across different time frames.

Main Results:

• Autonomy, competence, and relatedness consistently ranked among the top four most salient needs.
• These three needs, along with self-esteem, were strongly associated with positive event-related affect.
• Needs such as self-actualization, meaning, physical thriving, popularity, and wealth were found to be less fundamental.

Conclusions:

• The findings strongly support the postulates of self-determination theory regarding the fundamental nature of autonomy, competence, and relatedness.
• Psychological need satisfaction, particularly for autonomy, competence, and relatedness, appears critical for human flourishing.
• The results have implications for refining hierarchical models of human needs and understanding the drivers of life satisfaction.
