The authors also aim at promoting the use of the term in nursing practice and research when talking about cancer care. According to the authors, while psychological distress refers to the negative feelings or emotions affecting a person’s daily function, cancer-related psychological distress is different in that it could cause major psychiatric illness and symptoms of depression that are caused by the cancer diagnosis.Defining attributes of the conceptCancer-related psychological distress can be defined using four attributes: depression, anxiety, fear, and feeling discouraged. Depression refers to symptoms such as a lack of appetite and fatigue and is linked to a history of depression and lack of social support. Anxiety is an uneasiness of mind that comes because of the impending illness. Fear occurs when patients have lost a projected future while discouragement occurs when there is a loss of enthusiasm.Benefits of completing a Concept AnalysisCompleting a concept analysis for nursing theory development research and nursing practice is important as it helps to inform a nurse how to define a concept and how to use it in a study, how to select appropriate instruments to measure the concept, and how to use the concept in clinical practice.
