Objectives: theoretical validation of the concept of low self-efficacy in health as a nursing diagnosis construct. Methods: construction of a middle-range theory for validating diagnoses, comprised of five stages: definition of the approach for building the theory; definition of the main concepts; creation of a pictorial diagram; formulation of proposals; establishment of causal relationships and evidence for clinical practice. The main concepts were identified through a literature review and the studies were taken from the LILACS, SCOPUS, CINAHL and PubMed/MEDLINE databases. The final sample was comprised of 92 articles. Results: eighteen etiological factors and 16 clinical indicators were identified; characterized as antecedents and manifestations for inferring a diagnosis of low self-efficacy in health. Conclusions: the related concepts of the new nursing diagnosis of low self-efficacy in health, to be applied in clinical nursing practice, were identified and defined.

Objetivo: determinar la relación entre la capacidad de agencia de autocuidado y la autoeficacia percibida en personas con cardiopatía isquémica que asisten al programa de rehabilitación cardíaca, en una clínica privada de la ciudad de Neiva.Metodología: estudio correlacional, de corte transversal, con abordaje cuantitativo, basado en la teoría de déficit de autocuidados de Orem y la teoría de mediano rango de enfermería de autoeficacia de Resnick. La muestra estuvo constituida por 61 personas, a quienes se les aplicó la escala de apreciación de agencia de autocuidado, segunda versión en español, y la escala de autoeficacia general.Resultados: la mayoría de los participantes reportaron niveles altos de capacidad de agencia de autocuidado y de autoeficacia percibida; respecto a la asociación entre estas dos variables, a través de un análisis de correlación canónica se halló un resultado de rc=0,879, p<0,05, demostrando un grado fuerte de relación entre las variables agencia de autocuidado y autoeficacia percibida.Conclusión: la capacidad de agencia de autocuidado y autoeficacia percibida son fenómenos que se presentan de manera positiva en las personas con cardiopatías isquémicas que asisten al programa de rehabilitación cardíaca. Se confirmó la relación entre estas dos variables, demostrando que la autoeficacia percibida tiene influencia y posee efecto predictor sobre la capacidad de agencia de autocuidado.

Objectives: to analyze the impact of the Colombian Peace Agreement on the structural social determinants of health. Methods: a descriptive, ecological study, based on documentary data from 2008 to 2018. The records of victims, epidemiological indicators, and structural social determinants of health in Colombia were analyzed. Results: there was a correlation between the period in which the Peace Agreement process was developed and the indicators of structural determinants in health with p<0.05. With the Poisson regression analysis, the favorable correlations between the peace process and the determinants were confirmed, besides allowing the understanding of the changes in these indicators before the Peace Agreement. Conclusions: the implementation of the peace process has a positive impact on structural social determinants of health, which is observed by the beginning of the decrease of economic, educational, health, and social inequalities and inequities, a fact that offers the possibility of living in peace.
