          Abstract

          RESUMEN: Introducción. La incertidumbre es la dificultad para definir el significado de situaciones relacionadas con enfermedades; además, es fuente significativa de estrés psicosocial en su trayectoria. Los exámenes endoscópicos, aunque mínimamente invasivos, generan miedo e incertidumbre. El cáncer (gástrico, colorrectal) es una causa prematura de mortalidad; para su detección, son necesarias las ayudas diagnósticas, las cuales son generadoras de incertidumbre. Objetivo. Determinar el nivel de incertidumbre en las personas previo a la toma de una endoscopia o colonoscopia de acuerdo a la teoría de Mishel. Materiales y método. Estudio cuantitativo, descriptivo, transversal, muestreo no probabilístico por conveniencia. La muestra conformada por 477 participantes a quienes se les aplicó la “Escala de Incertidumbre en la Enfermedad de Merle Mishel”, adaptada para procedimientos diagnósticos en el año 2017, con Alfa de Cronbach 0.90. El análisis estadístico se realizó con cálculo de medidas de tendencia central, de dispersión y medidas de posición. Resultados. La edad promedio fue de 53 años, el 51,5 % presentó nivel moderado de incertidumbre; a mayor escolaridad menor incertidumbre (p = 6,286), la dimensión con mayor nivel de incertidumbre fue la complejidad. Conclusiones. La incertidumbre que genera una situación como el diagnóstico de una enfermedad crónica, causa en los individuos un estado estresante; la aplicación de la teoría de Mishel orienta al profesional de enfermería a identificar el nivel de incertidumbre generando mecanismos de afrontamiento para lograr la adaptación a los resultados expuestos.

          ABSTRACT: Introduction. Uncertainty is one of the difficulties in defining the meaning of situations related to diseases; it is also a significant source of psychosocial stress during their trajectory. Endoscopic exams, although minimally invasive, generate fear and uncertainty. Cancer (gastric, colorectal) is a premature cause of mortality; diagnostic aids are necessary for its detection, which generate uncertainty. Objective. This work sought to determine the level of uncertainty in people prior to an endoscopy or colonoscopy procedure, according to Mishel’s theory. Materials and Method. Quantitative, descriptive, cross-sectional study, non-probability convenience sampling. The sample was made up of 477 participants who were administered "Merle Mishel’s uncertainty in disease scale", adapted for diagnostic procedures in 2017, with Cronbach's alpha of 0.90. The statistical analysis was performed by calculating measures of central tendency, dispersion, and position measures. Results. The mean age was 53 years, 51.5% had moderate level of uncertainty; the higher the level of education, the lower the uncertainty (p = 6.286), the dimension with the highest level of uncertainty was complexity. Conclusions. Uncertainty caused by a situation, such as the diagnosis of a chronic disease causes a stressful state in individuals. Application of Mishel’s theory guides nursing professionals to identify levels of uncertainty by developing coping mechanisms to achieve adaptation to the results exposed.

          Illness uncertainty, coping, and quality of life among patients with prostate cancer

          Illness uncertainty is a significant source of psychological distress that affects cancer patients’ quality of life (QOL). Mishel’s uncertainty in illness theory (UIT) proposes that illness uncertainty influences an individual’s use of coping strategies, and directly and indirectly influences their QOL. This study tested the relationships depicted in the adapted UIT in cancer patients. This cross-sectional study is a secondary analysis of the baseline data from a randomized clinical trial ( N = 263 prostate cancer patients). Patients were diagnosed with localized (64.6%), biochemical recurrent (12.6%), or advanced (22.8%) prostate cancer. Uncertainty, coping (avoidant and active coping strategies), and QOL (physical and mental well-being) were measured using the Mishel’s uncertainty of illness scale, Brief COPE, and the Medical Outcomes Study 12-item short form (SF-12), respectively. We used path analysis to achieve the research aim. Patients’ illness uncertainty directly, negatively influenced their physical well-being ( P < .001) and mental well-being ( P < .05). Patients’ illness uncertainty was positively related to their avoidant coping strategies ( P < .001). Patients’ active and avoidant coping strategies influenced their mental well-being ( P < .001). Uncertainty also negatively influenced mental well-being through avoidant coping strategies. The model had excellent fit to the data. Our findings have indicated the potential of improving QOL by decreasing illness uncertainty and reducing avoidant coping strategies. Future research is needed to better understand the complex relationships between illness uncertainty, coping strategies, and domains of QOL among patients with different types of cancer using longitudinal research.
