Hello, my name is Brandi Miller. My classmates, Marcie Chenette, Mariah Lab, Tamara Putney, and I, invite you to join us as we explore Merle Mishels uncertainty in illness theory. This presentation was created as part of the Ferris State University Master of Science in Nursing program.
Mishels original 1988 theory proposed that managing uncertainty is necessary to adapt during illness. She developed a framework to describe how individuals process the events surrounding illness. In 1990, Mishel updated her theory to better apply to chronically ill patients. Since the original conception of the uncertainty in illness theory, Mishel and other researchers have conducted several studies that support and apply the theorys constructs.

2Theory OverviewOriginal 1988 TheoryBailey & Stewart, 2010Mishel, 1981Mishel, 1988
Mishel began her work in 1981 when she developed a 30-item scale to measure uncertainty, a key concept in her original 1988 theory. In formulating the original theory, Mishel recognized that a persons stimuli frame could reduce uncertainty in illness. The stimuli frame is composed of the symptom pattern, event familiarity, and event congruence (or the consistency between expected and experienced events). In addition, she proposed that a persons stimuli frame could be enhanced by his or her cognitive capacities and structure providers. Structure providers include credible authorities like doctors and nurses, and also social supports. These concepts are grouped together as the antecedents of uncertainty.
Uncertainty occurs when individuals are unable to determine the meaning of illness-related events. Individuals appraise uncertainty as either a danger or an opportunity using inference and illusion. Inference is the process of evaluating a situation based on past experiences. Whereas, illusion is the process of constructing positive beliefs.
When a person appraises uncertainty as dangerous, he or she copes by reducing the uncertainty and managing the emotions caused by it. Conversely, when a person appraises uncertainty as an opportunity, he or she uses coping strategies aimed at maintaining the uncertainty. Based on Mishels original theory, people only view uncertainty as an opportunity when the alternative is facing the certainty of a poor outcome. Using appropriate coping strategies, individuals adapt to their illness.
[1 min 38 sec]3Theory OverviewReconceptualized 1990 Theory
Bailey & Stewart, 2010Mishel, 1990
Research completed after publication of Mishels original theory supported its application to acutely ill patients, but did not support the theorys application to chronically ill patients or those facing recurrence of a disease in remission. These patients initially viewed uncertainty as dangerous, but over time came to accept it as an opportunity. This conflicted with Mishels original theory, which proposed that only individuals faced with the certainty of poor outcomes would view uncertainty as an opportunity.
Therefore, Mishel updated her work in 1990 to accommodate the response over time of chronically ill patients and those facing disease recurrence. Recognizing the cultural bias inherent in her original work, she abandoned the Western mechanistic assumption that adaptation is the single desired outcome and that uncertainty in illness is a linear trajectory.
The new model proposed that under conditions of chronic uncertainty, people move away from evaluating uncertainty as dangerous and adopt a new world view that accepts uncertainty as part of life. The reconceptualized model also introduced the concept of probabilistic thinking, or the ability to consider multiple ways of accomplishing goals. When people with chronic illnesses or disease remission accept uncertainty as part of life, they perceive it as an opportunity to grow and change.
[1 min 32 sec]4Mishel, 1990Mishel, 1999Mishel, 2014Metaparadigm Concepts
While the metaparadigm concepts are not explicitly defined in Mishels theory, they can be implicitly derived.
Mishel explains that human experience is one of the most important elements of her theory, which focuses on both individuals and families. Feelings of uncertainty can cross all stages of illness, even after the acute phase is over, because the question of disease recurrence is a big factor in the level of uncertainty a person feels.
The environment is an open system that exchanges energy and matter with the person. External environment includes the persons stimuli frame and structure providers, and internal environment encompasses his or her cognitive capacities.
Uncertainty and mechanisms of coping are imperative to the perceived health and wellbeing of the individual. Uncertainty contributes to maladaptive coping mechanisms and health problems. Utilizing a theory based tool, measurement of uncertainty can facilitate the design of effective interventions to promote coping.
The role of nursing is to accept and promote probabilistic thinking and to avoid focusing on predictability and certainty. Nurses promote consideration of alternatives that allow their patients to adjust to the changing nature of their illness and foster the notion that there are many factors that influence a patients response to illness.

Bailey & Stewart, 2010Dudley-Brown, 1997Mishel, 1999
Dudley-Brown proposed several criteria to evaluate nursing theories. An abbreviated analysis of the uncertainty in illness theory is presented using the criteria of accuracy, simplicity, scope, acceptability, and sociocultural utility.
Accuracy describes how well the theory applies to the real world of nursing today. Nurses responsible for different types of patient populations incorporate uncertainty concepts into their plans of care. The uncertainty in illness theory has been tested and shown to be accurate in both research and clinical settings and is frequently used in nursing education as an exemplar of middle-range nursing theories.
Simplicity is based on the number of phenomena and relationships described by a theory. The uncertainty in illness theory has 11 major concepts and three themes in the original theory, and several new concepts were introduced in the reconceptualized theory. While the antecedents of uncertainty are clear and concise, both the appraisal process and coping phase are complex. However, Mishel constructed the theory to be very functional when used appropriately with the designed tools.

Bailey & Stewart, 2010Mishel, 1999UNC School of Nursing, 2014 Wright, Afari, & Zautra, 2009
By definition, middle-range theories are more narrow in scope than nursing philosophies or conceptual models. This theory applies strictly to uncertainty caused by illness, and was originally used only with cancer patients. However, it is generalizable across many patient populations. Research has been conducted assessing uncertainty in illness on children and adults with all forms of acute, chronic and terminal illness.
The uncertainty in illness theory is widely accepted in the nursing community and has been used in practice, education, and research. Empirical testing carried out by Mishel and others supports the relationships among the concepts, assumptions, and variables proposed by the theory. Mishel has secured grants and funding from the National Institute of Nursing Research and the National Cancer Institute for over twenty years.
Sociocultural utility defines how well a theory includes different cultures and if it is significant to humanity. The uncertainty in illness scale and theory have been used in eight countries outside the U.S. and have been translated into 15 languages. The theory has been tested on people of varying gender, age, race, and ethnicity, and has also been applied to families. It has been used to predict uncertainty in many different diagnoses including breast and prostate cancer, cardiac disease, and schizophrenia.

Research ArticleOutcomes of an uncertainty management interventionPurposeInterventionMethodFindingsConclusion and implications
Germino et al., 2013
Examining a research study allows one to see how Mishels theory can be used in practice. The name of this study is: Outcomes of an Uncertainty Management Intervention, in Younger African American and Caucasian Breast Cancer Survivors (Germino et al., 2013).
In this 2013 study, researchers reported the outcomes of an uncertainty management intervention in young breast cancer survivors.The purpose of the study was to determine if a tailored intervention reduced uncertainty, facilitated fewer breast cancer-specific concerns, and produced more positive psychological outcomes.
Participants in the intervention group received a CD and a guidebook that provided strategies to control uncertainty and promote self-efficacy.They also received four weekly follow-up calls to reinforce the strategies.Participants in the control group received four weekly supportive telephone calls to control for the time researchers spent with the intervention group.
Breast cancer survivors receiving the intervention reported decreased uncertainty and improved coping.The intervention allowed breast cancer survivors to easily access information, resources, and management strategies.The tools can be adapted for use on a variety of electronic devices.

8Theory ReflectionPurpose:Appropriate interventions decrease uncertaintyHypothesis:Less uncertaintyBetter uncertainty managementFewer concernsMore positive psychological outcomesMethods:Theory derived scalesDesigned to address antecedents of uncertainty
Germino et al., 2013
The uncertainty in illness theory was explicitly named by the breast cancer study authors as the theoretical basis for the research, and was foundational to the study purpose, hypothesis, and design. The theory provided a framework for selecting interventions to improve outcomes under conditions of uncertainty.
The purpose of the study was to show that with proper interventions there would be a decrease in uncertain feelings in patients who are experiencing cancer or remission.According to the theory, the antecedents of uncertainty can be managed by interventions designed to facilitate a new world view where uncertainty is regarded as an opportunity.
The authors of the study hypothesized that the women who received the intervention, in comparison to women in the control group, would have less uncertainty, better uncertainty management, fewer concerns,and more positive psychological outcomes.
The uncertainty in illness theory was also integrated into the study methods. Uncertainty was measured using scales based on the theory and interventions were designed to reduce uncertainty by addressing its antecedents.

9With no theoretical framework:Uncertainty concepts would lack clarity and measurabilityNo existing knowledge to compareStudy less meaningful
Germino et al., 2013University of Southern California, 2013
Implications of Framework
Utilizing a theory in research allows for prediction, explanation, and, at times, control of phenomena (University of Southern California, 2013). The researchers in the breast cancer survivor study integrated the uncertainty in illness theory in all aspects of their study design (Germino et al., 2013). Key concepts from the theory were incorporated into the study purpose and hypothesis. Their research not only drew significantly from past studies, but also expanded on the knowledge generated. Variables and interventions were selected and designed to correspond with theory concepts, and the data were analyzed and interpreted within the constructs of the theoretical framework. Without the theoretical framework of Mishels uncertainty in illness theory, study concepts would lack clarity and there would be no mechanism to measure uncertainty. In other words there would be no link to existing knowledge, so the results of the study would be less meaningful.

10Implications of FrameworkFramework based on nursing theoryAppropriatenessClear conceptual definitionsGuided by propositional statementsOperational definitions providedStudy findings support framework
Germino et al., 2013Nieswiadomy, 2012
Nieswiadomy [pronounced ness-we-odomy] asserts in the book Foundations of Nursing Research that a theoretical or conceptual framework should be used in all studies. Using her guidelines to critique the breast cancer survivor study framework, it fares quite well. The study framework is clearly identified in the research and it is based on a middle-range nursing theory: the theory of uncertainty in illness. The study appropriately incorporated the theoretical concepts, definitions, and relationships throughout all aspects of the research design. Theoretical propositions were used to develop the research hypothesis. Using the Survivor Version of the Mishel Uncertainty in Illness Scale and the Growth through Uncertainty Scale, operational definitions were provided. The study findings were related to the uncertainty in illness theoretical framework and support the theory relationships.

11Theory in PracticeOperating room managementUncertainty related to post-operative symptomsPre- and post-operative education can decrease uncertaintyNursing clinical instructionEasy to teach and widely applicableValuable tool for care planning
Merle Mishels theory is useful in practice. Here are some examples to show how the theory can be applied to our individual practices.
Patients have many reasons to be uncertain prior to surgery. Surgical nurses like Marcie must ask the right questions to ensure that patients have adequate knowledge and resources. Education begins in the physicians office, then patients speak with a pre-anesthesia nurse. On the day of surgery, a pre-op assessment is completed, and prior to discharge, the patient is given printed discharge instructions. Education should be patient specific based on the surgery and the needs of the patient.
MerleMishelstheory can be applied to Mariahs role as an adjunct nursing instructor by teaching the students how to apply this theory to their patients. This theory is a good learning tool for students to understand that the patients they encounter might all have some level of uncertainty. The students will be better prepared to converse with their patients about the illness or diagnosis once they better understand the patients state of mind.
[1 min 6 sec]12Theory in PracticeHospital telemetry unitUncertainty predicts depression in female heart failure patientsNurses can design gender-specific interventionsHospital critical care unitLaryngectomy patients experience fear and traumatic thoughtsAppropriate interventions can assist in coping and relaxation
Kao et al., 2013
I work on a telemetry unit and often care for patients with congestive heart failure and other comorbid, chronic issues. Several studies have examined how the uncertainty in illness theory can be used with these patients. Using the Mishel Uncertainty in Illness Scale, Kao and colleagues found that uncertainty was a predictor of depression in female heart failure patients. Nurses can use this information to design gender-specific interventions aimed at reducing uncertainty in this population.
Tamara works in the intensive care unit and often cares for patients recovering from a laryngectomy due to laryngeal cancer. These patients can experience traumatic thoughts and fear related to their illness. Through the use of Mishels assessment tools, interventions can be developed to help patients relax during or after triggering events, or with coping in everyday life.Offering the patient the best possible resources and materials related to the illness and ensuring open lines of communication are very important.

Link Between Theory & PracticeEmpirics EstheticsPersonal knowledgeEthics
Carper, 1978
Thetheory of uncertainty in illness can be described usingCarpers fundamental patterns of knowing in nursing (Carper, 1978). Mishelswork organizes nursing knowledge into alogical theory that has been empirically tested and found to be reliable.The theory integrates abstract and systematic explanations to characterize the impact of uncertainty and suggest avenues to reduce it. Using the art of nursing, or esthetics, nurses help patients explore what uncertainty means and design unique interventions to help patients cope. Nurses develop authentic relationships with patients to facilitate the exploration and resolution of uncertainty.They recognize that patients are constantly changing and promote probabilistic thinking to help patients internalize uncertainty as an opportunity. Nurses also help patients face moral and ethical dilemmas, such as viewing uncertainty as an opportunity when the alternative is the certainty of a downward trajectory.

14Link Between Theory & PracticeInteractions with people are never the sameNursing knowledge is uniqueCarpers patterns of knowing help distinguish relationships of phenomena seen in practiceState of health is in constant fluxArticle shows treatments must be holistic and approached from many angles to be effective
Carper, 1978Fiandt, Forman, Megel, Pakieser, & Burge, 2003Germino et al., 2013
Designing interventions for the varying actions of people is difficult. In order to produce desired patient outcomes, the knowledge and education nurses possess must be unique. Using Carpers (1978) patterns of knowing helps definenursing knowledge. Eventhough there is a clear need for a holistic team approach to patient care, the medical model of care still dominates(Fiandt,Forman, Megel, Pakieser, & Burge, 2003). Most healthcare professions focus on one specialty or body organ.Nursing is unique in that the profession is concerned with the person as a whole and recognizes the best way to optimize patient outcomes is to take a holistic approach. Nurses must use their unique knowledge to understand that health is in a constant state of flux.
The research done by Germino and colleagues (2013) shows that care and treatment of patients must be approached from many angles.It demonstrates the complex relationships people share with metaparadigm systems around them.The patients in the study responded to interventions of all kinds designed to allow them to use what was most helpful.

ConclusionTheory overviewAbbreviated analysisUse in researchUse in practiceLink between unique nursing knowledge and nursing practice
Fear. Uncertainty. What does the future look like? Many people diagnosed with an illness ask questions to understand their disease, but they are fearful. Merle Mishels theory of uncertainty in illness allows nurses to help patients comprehend and deal with their uncertainty. It can be used to develop innovative strategies to enhance coping, reduce uncertainty, and help patients grow through their illness experience. The uncertainty in illness theory uniquely defines the metaparadigm concepts of person, environment, health, and nursing. It has been shown to be accurate and functional, and can be broadly applied to a variety of nursing practice settings. It is widely accepted by the nursing community, and has been translated across several cultures. The uncertainty in illness theory has been used in a variety of research studies, including the breast cancer survivor study profiled in this presentation. The theory is useful and demonstrates the unique link between nursing knowledge and practice.
