Occupational theory is an important component of occupational therapy, which emphasizes the strong link between fulfilling activities and happiness. It asserts that involvement in meaningful activities is necessary for overall health. According to this theory, when people engage in activities that align with their interests and objectives, they find fulfillment and advance their skills. Occupational therapists use this theory to assess how a person’s environment and physical, emotional, and cognitive factors interact to affect daily functioning.

The importance of occupation in therapy is emphasized by this theory, which acknowledges that meaningful work can positively impact one’s physical, psychological, and social well-being.
