Psychometric properties of the Connor-Davidson Resilience Scale (CD-RISC) in the Spanish population

Although the number of studies in the literature on the psychometric properties of the CD-RISC measures is remarkably high, there is still a great lack of consensus about its internal structure among the general population. Therefore, the aim of this study has been threefold: to analyze the psychometric properties, explore the factorial structure and calculate percentiles of the Connor-Davidson Resilience Scale (CD-RISC) for a sample of the Spanish population. For this purpose, the study sample consisted of 1119 participants consisting of 324 males and 795 females and they completed the following scales: CD-RISC, Perceived Stress Scale, Multidimensional Scale of Perceived Social Support, General Self-Efficacy Scale, Stress Vulnerability Inventory, Personality Hardiness Questionnaire and the anxiety and depression subscales of the SCL-90-R. In terms of reliability, an adequate Cronbach's coefficient alpha value of .86 was obtained. The evidence for the validity of the internal structure supports the unidimensionality of the CD-RISC measurements, as well as confirming the expec-ted theoretical relationships and correlating with the described measures in the expected direction. Satisfactory results are obtained in the present study that reinforce the usefulness and precision of this scale for its application using the Spanish population, presenting percentiles that can provide guidance in the interpretation and use of the scores with respect to its application in both research and clinical practiceAunque el número de estudios sobre las propiedades psicométricas de la CD-RISC es notablemente amplio, aún hay gran falta de consenso sobre su estructura interna en población general. Por ello, el objetivo de este estudio ha sido triple, verificar sus propiedades psicométricas, ex-plorar la estructura factorial y calcular baremos de la escala de resiliencia CD-RISC para una muestra de población española. Para ello participaron 1119 personas, 324 hombres y 795 mujeres, cumplimentando las siguientes escalas: CD-RISC, Escala de Estrés Percibido, Escala de Apoyo Social Percibido, Escala de Autoeficacia, Escala de Vulnerabilidad al Estrés, Cuestionario de Personalidad Resistente y subescalas de ansiedad y depresión del SCL-90. Las evidencias de validez confirmaron las relaciones teóricas esperadas correlacionándose con las medidas descritas. El análisis factorial encontró un apoyo razonable a la hipótesis de unidimensionalidad. En cuanto a la fiabilidad se obtuvieron valores aceptables con un alfa de .86 y una omega de .86. Se obtienen resultados satisfactorios que refuerzan la utilidad y precisión de esta escala para su uso en población española, apoyando la hipótesis de unidimensionalidad y aportando baremos que permiten interpretar las puntuaciones para su aplicación tanto en investigación como en la práctica clínica

Proyecto PRIC: Protección Robotizada de Infraestructuras Críticas

Esta comunicación resume los trabajos realizados por el Grupo de Robótica y Cibernética (RobCib) del Centro de Automática y Robótica (CAR), formado por UPM y CSIC, en el contexto del proyecto PRIC (Protección Robotizada de Infraestructuras Críticas). Este proyecto tiene como objetivo el desarrollo de sistemas robóticos capaces de vigilar las infraestructuras críticas, detectando las potenciales amenazas e interviniendo cuando sea necesario. Algunos de estos trabajos están encaminados a la detección de anomalías visuales y acústicas, la detección, predicción e interceptación de intrusos, el desarrollo de un robot de pequeño tamaño y un manipulador híper-redundante para intervenir en áreas de difícil acceso, el diseño de una interfaz para misiones multi-robot y la adaptación de herramientas comunes en el mundo de la robótica a los escenarios multi-robot

Role of biological and non biological factors in congestive heart failure mortality: PREDICE-SCORE: A clinical prediction rule

Background: Congestive heart failure (HF) is a chronic, frequent and disabling condition but with a modifiable course and a large potential for improving. The aim of this project was to develop a clinical prediction model of biological and non biological factors in patients with first diagnosis of HF that facilitates the risk-stratification and decision-making process at the point of care. Methods and Results: Historical cohort analysis of 600 patients attended at three tertiary hospitals and diagnosed of a first episode of HF according Framingham criteria. There were followed 1 year. We analyzed sociodemographic, clinical and laboratory data with potential prognostic value. The modelling process concluded into a logistic regression multivariable analysis and a predictive rule: PREDICE SCORE. Age, dependency for daily basic activities, creatinine clearance, sodium levels at admission and systolic dysfunction diagnosis (HF with left ventricular ejection fraction < 40%) were the selected variables. The model showed a c-statistic of 0.763. PREDICE Score, has range of 22 points to stratifications of 1-year mortality. Conclusions: The follow-up of 600 patients hospitalized by a first episode of congestive HF, allowed us to obtain a predictive 1 year mortality model from the combination of demographic data, routine biochemistry and easy handling social and functional variables at the point of care. The variables included were non-invasive, undemanding to collect, and widely available. It allows for risk stratification and therapeutical targeting and may help in the clinical decisions process in a sustainable way
