Self-Care Deficit Theory, developed by Dorothea Orem, focuses on the individual's ability to perform self-care activities necessary for maintaining health and well-being. The theory posits that when individuals cannot meet their own self-care needs due to limitations, a deficit occurs. This can arise from various factors, including illness, injury, or lack of knowledge. To address this deficit, healthcare providers must assess the individual's self-care capabilities and provide support or education as needed. The goal is to empower individuals to regain their ability to care for themselves, promoting independence and improving overall health outcomes.
