Abstract: Se realizó la construcción y validación de un test psicométrico para la determinación de vulnerabilidad al estrés. El test, denominado cuestionario vulnerabilidad estrés, fue realizado básicamente a partir de la batería psicométrico del método de enfoque sistémico de evaluación del estrés. Se confeccionó un cuestionario inicial de 63 ítems y 3 subescalas con el que se realizó un estudio piloto; al depurarlo, la forma definitiva fue redactada con 39 ítems y sometida a un estudio para determinar fiabilidad y validez. Se determinó una estructura trifactorial coincidente con el dise o previo. La consistencia interna fue de 0,92 según el alfa de Cronbach y de 0,90 con el coeficiente de Spearman-Brown. Se encontró una correlación test-retest de 0,97 y se correlacionó además, de forma significativa con criterios externos de vulnerabilidad-escala de neuroticismo del test de Eysenck, ansiedad como rasgo de Spielberger y el criterio clínico. Se concluyó que el cuestionario vulnerabilidad estrés constituye un instrumento válido y fiable para medir vulnerabilidad al estrés sobre la base del método de enfoque sistémico.

Abstract: Para determinar la correlación entre las pruebas psicométricas que utiliza el método de enfoque sistémico de evaluación del estrés, así como la estructura factorial entre estas, se realizó el análisis de los registros psicométricos de 114 sujetos sometidos a estrés, que incluyeron: test de actividad nerviosa superior de Strelau, inventario de personalidad de Eysenck, patrón de conducta tipo A, ansiedad rasgo-estado de Spielberger y vulnerabilidad al estrés de Miller y Smith. Se utilizó el coeficiente de correlación de Pearson y el análisis de componentes principales con el método de rotación Varimax con Kaiser. Se encontró la existencia de correlaciones significativas entre la mayor parte de las pruebas analizadas, lo que se atribuyó a la medición de similares procesos psicológicos con diferentes instrumentos. Además, se precisó la existencia de una estructura bifactorial, con un primer factor relacionado con la inhibición, neuroticismo y ansiedad rasgo-estado, y un segundo factor relacionado con la excitación y la movilidad. Existió concordancia de los resultados con los criterios de evaluación del método de enfoque sistémico de evaluación del estrés.

Abstract: The inspirals of stellar-mass mass compact objects into massive black holes in the centres of galaxies are one of the most important sources of gravitational radiation for space-based detectors like LISA or eLISA. These extreme-mass-ratio inspirals (EMRIs) will enable an ambitious research program with implications for astrophysics, cosmology, and fundamental physics. This article is a summary of the talks delivered at the plenary session on EMRIs at the 10th International LISA Symposium. It contains research updates on the following topics: astrophysics of EMRIs; EMRI science potential; and EMRI modeling.
