In Units 3 And 4 You Examined Theories From Other Disciplines That Ar

In Units 3 and 4, you examined theories from other disciplines that are used in nursing. Some of these theories are used without modification in nursing such as Lewin’s Change Theory to support practice changes. Other theories are used as a foundation for development of nursing theories such as Peplau’s Theory of Interpersonal Relations founded on the work of Harry Stack Sullivan. Clearly, many non-nursing theories are used in the development of middle range theories in nursing. Identify a middle range theory in nursing that has links to a non-nursing theory.

Describe the theory and explain the relationship to the related non-nursing theory. Connect the selected middle range theory to nursing research or advanced nursing practice. (Use at least 3 references from the year 2015 and above) (use APA style 7)

Paper For Above instruction

The selected middle-range theory for this discussion is the Theory of Uncertainty in Illness, developed by Merle Mishel. This theory has significant roots in the non-nursing discipline of cognitive psychology, particularly the work on uncertainty and information processing. Mishel’s theory was designed to understand how patients interpret and manage their illness-related uncertainties, which directly influences their psychological adjustment and health outcomes (Mishel, 1988). Over time, this theory has been refined and extensively used in nursing research to improve patient care strategies and outcomes, especially in chronic illness management (Gligorov et al., 2018).

The non-nursing theory underpinning the Theory of Uncertainty in Illness is rooted in the cognitive psychological understanding of uncertainty, decision-making, and information processing. Cognitive psychology posits that individuals strive to reduce uncertainty through the acquisition and interpretation of information (Ladouceur et al., 2017). Mishel adapted these principles to health, emphasizing how patients interpret ambiguous symptoms and uncertain diagnoses to make meaning of their illness experiences. This connection underscores a shared focus on internal cognitive processes influencing behavior and perception, which is central to both theories.

The relationship between the Theory of Uncertainty in Illness and cognitive psychology is evident in the emphasis on how individuals manage ambiguity and make sense of complex information regarding their health. Mishel’s model describes how patients use appraisal procedures—either a pattern of thought or information seeking—to reduce uncertainty (Mishel, 1988). This approach aligns with cognitive psychological theories that focus on thought patterns, perception, and decision-making. In nursing practice, understanding these processes helps nurses develop tailored interventions to reduce uncertainty, foster coping mechanisms, and improve patient outcomes (Gligorov et al., 2018).

In the context of nursing research, the Theory of Uncertainty in Illness has facilitated studies exploring how uncertainty impacts patient adaptation and health behavior. For example, research demonstrates that high uncertainty correlates with increased anxiety and decreased quality of life among cancer patients (Yan et al., 2019). This theoretical framework guides the development of interventions aimed at information provision, education, and support strategies to help patients manage their health uncertainties better (Heng et al., 2020). Moreover, in advanced nursing practice, its applications extend to patient education, shared decision-making, and psychosocial support, emphasizing holistic care that addresses cognitive and emotional dimensions (Gligorov et al., 2018).

In conclusion, the Theory of Uncertainty in Illness exemplifies how a non-nursing theory rooted in cognitive psychology has profoundly influenced the development of a significant nursing middle-range theory. Its focus on patient cognition and information processing bridges psychological principles with practical nursing interventions, fostering improved patient outcomes through targeted communication and support strategies. The ongoing application of this theory in research and practice highlights its relevance in advancing nursing knowledge and addressing complex patient needs in diverse clinical settings.
