Abstract :

The Unpleasant Symptoms Theory, one of the medium scale theories, has been developed to integrate various symptoms and existing relevant data. Theory is available for understanding the symptom experiences in various cases and prevention, alleviation and management of unfavorable symptoms and their negative effects. Symptoms occuring together are depicted as catalyzing each other. Thus, this theory allows for the presence of multiple symptoms and implies that management of one symptom will contribute to the management of other symptoms. The purpose of theory is to the theory is to improve understanding of the symptom experience in various contexts and to provide information useful for designing effective means to prevent, ameliorate, or manage unpleasant symptoms and their negative effects. Because it is more general than a theory describing or explaining a specific symptom. The Unpleasant Symptoms Theory has three major concepts such as symptom(s), effective factors and performance outcomes. Symptom(s) has been the starting point in conceptualization of the theory and therefore they should be accepted as the central concept of the theory. The three factors influencing the symptom experience were defined as physiological, psychological and situational factors. Three categories of factors that influence the symptom experience (and can, in turn, be influenced by it and by one another) are identified in the theory: physiologic factors, psychologic factors, and situational factors.The outcome concept in the The Unpleasant Symptoms Theory is performance. Performance represents the outcomes of the symptom experience. The concept of performance has several possible dimensions: physical activity and impairment, functional role performance, activities of daily living, cognition, comprehension, learning, concentration, problem solving and social interactions. The theory of unpleasant symptoms, which was grounded in clinical research and practice, is a mid-range theory that holds considerable promise as a basis for additional research and as a guide to nursing practice. In this article the The Unpleasant Symptoms Theory has been explained.
