Betty Neuman’s Systems Model is a comprehensive, holistic, and system-based perspective on nursing and health. It focuses on the individual as an open system in dynamic interaction with their environment, including physical, psychological, social, and spiritual factors. The model proposes that individuals have normal lines of defense susceptible to stress and change. The nurse’s role is to support the individual’s lines of defense and help maintain their balance.

Imogene King’s Goal Attainment Theory

Imogene King’s Goal Attainment Theory focuses on the interaction between the individual and the environment and the individual’s goal-directed actions and interactions. Specifically, the theory proposes that the nurse and the individual work together to set and achieve mutually agreed-upon goals and that the nurse plays a crucial role in helping the individual attain their goals.

Contemporary Nursing Theories

The theory proposes that the nurse plays a crucial role in helping individuals identify their self-care needs and develop the necessary skills to meet them.

Differences between Theories

Early nursing theories focus more on the medical aspects of nursing and view the patient as a passive recipient of care. Nonetheless, Mid-20th-century theories expanded this view to include the patient’s environment and social factors that impact their health.

Application of Nursing Theories in Clinical Practice

Assessment and Diagnosis

Nursing theories are used in the assessment and diagnosis phase of patient care by providing a framework for understanding the patient’s needs and determining the best course of action. For example, Orem’s Self-Care Deficit Theory helps identify areas where patients may need support in managing their health.

Planning and Interventions

Nursing theories also inform the planning and intervention phase of patient care. Using Roy’s Adaptation Model, for example, a nurse can identify areas where the patient may need support to adapt to changes in their environment or health.

Evaluation of Patient Outcomes

Finally, nursing theories can evaluate patient outcomes by providing a standard for measuring the effectiveness of care. For example, Imogene King’s Goal Attainment Theory determines if health providers meet the patient’s goals for their health.

Challenges and Future of Nursing Theories

Criticisms of Nursing Theories

Critics of nursing theories argue that they can be too abstract and may not always be applicable in clinical practice. Additionally, some theories may not be well understood or widely used, leading to difficulty in their implementation.

Future Developments in Nursing Theories
