Cardiovascular reactivity to a marital conflict version of the Trier social stress test in intimate partner violence perpetrators
2014
Intimate partner violence (IPV) perpetrators have been categorized into two groups based on their heart rate (HR) reactivity to stress following Gottman's studies. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II or reactive perpetrators present a hyper-reactivity in anticipation of stress. In this study, changes in HR, pre-ejection period (PEP), vagal ratio as well as psychological state variables (anxiety and anger) in response to stress were assessed, comparing a group of type II IPV perpetrators (based on violence reports and psychological assessment; n = 17; mean age = 37) with non-violent controls (n = 17; mean age = 35) using modified version of the T…
How are neuroticism and depression related to the psychophysiological stress response to acute stress in healthy older people?
2015
Neuroticism and depressive symptomatology have been related to a heightened and diminished physiological stress response, which may partly explain their negative relationship with health and wellbeing. Identifying factors that may increase disease vulnerability is especially relevant in older people, whose physiological systems decline. With this in mind, we investigated the influence of neuroticism and depression on the psychophysiological stress response in healthy older people (from 55 to 76years old). A total of 36 volunteers were exposed to a stressful task (Trier Social Stress Test, TSST), while 35 volunteers performed a control non-stressful task. The physiological stress response wa…
Quality-of-Life and Economic Outcomes of Assessing Fractional Flow Reserve With Computed Tomography Angiography: PLATFORM.
2015
International audience; BACKGROUND: Fractional flow reserve estimated using computed tomography (FFRCT) might improve evaluation of patients with chest pain. OBJECTIVES: The authors sought to determine the effect on cost and quality of life (QOL) of using FFRCT instead of usual care to evaluate stable patients with symptoms suspicious for coronary disease. METHODS: Symptomatic patients without known coronary disease were enrolled into 2 strata based on whether invasive or noninvasive diagnostic testing was planned. In each stratum, consecutive observational cohorts were evaluated with either usual care or FFRCT. The number of diagnostic tests, invasive procedures, hospitalizations, and medi…
Stress test based on Oliver Wyman in Bank of Spain: an evaluation
2016
This paper, based on econometric techniques, has done a study to improve the predictions of the stress test, concerning the estimation of impairment losses. The main results obtained are: 1) the impact of the explanatory variables on the impairment loss is different at stages of growth, compared to times of recession; 2) there is a certain inertia of the dependent variable, but this inertia is different in intensity, and even the sign in the growth stages concerning the stages of recession; 3) of the explanatory variables, nominal GDP and equity are those that have a greater impact on the impairment loss; 4) finally, the two dummy variables that assess the impact of adjustment to market val…
El ciclo económico y la morosidad
2016
Basado en las variables utilizadas por el informe de Oliver Wyman, modificando y eliminado las redundantes, se elabora un modelo econométrico para estimar la morosidad de las entidades de crédito españolas. Las variables son el PIB, el deflactor, el desempleo, la bolsa, los créditos, el Euribor, el precio de las viviendas el tipo de cambio y na variable ficticia para que representa el SAREB. Además se contrasta si el modelo es óptimo para para largos periodos de tiempo. Los resultados obtenidos evidencian que el modelo construido con datos provenientes de épocas de recesión no es válido para épocas de crecimiento.
Econometric model to estimate the Probability of Default and Loss Given Default in the EBA stress test in 2016
2019
In this research, an econometric with panel data using Ordinary least squares OLS model is constructed following the guidelines recommended by the EBA stress test methodology for 2016. The findings indicate that macroeconomic factors affecting defaults are the expected ones in the Spanish credit institutions. However, loan impairments do not follow the patterns that a priori would be normal. Divergent is outcomes in defaults and impairments: the Non-Performing Loans (NPL) is pro-cyclical and impairment losses are counter-cyclical.
Cognitive emotion regulation withstands the stress test: An fMRI study on the effect of acute stress on distraction and reappraisal
2021
Cognitive emotion regulation is a key mechanism for the maintenance of mental health, but may fail, when individuals are exposed to acute stress. To date, it is not well understood whether and to what extent acute stress effects contribute to impairments in emotion regulation capacities as the sparse existing studies have yielded heterogeneous results, indicating that stress timing might be a crucial factor.In the present study, 81 healthy participants underwent either an acute stress task (ScanSTRESS-C; n = 40) or a control condition (n = 41) while lying in the MRI scanner. In the subsequent Cognitive Emotion Regulation Task (CERT), participants were confronted with neutral or negative pic…
Individual Differences in the Psychobiological Response to Psychosocial Stress (Trier Social Stress Test): The Relevance of Trait Anxiety and Coping …
2014
The main objective of this study was to investigate the contribution of some personality traits to the physiological and psychological response to a standardized laboratory psychosocial stressor (trier social stress test). Cortisol and affective response (anxiety and mood) were analysed in a mixed-sex group composed of 35 young adults who participated in a crossover design (18 men and 17 women). After verifying a statistically significant response to the trier social stress test in all parameters studied in both sex groups, exploratory cluster analyses were carried out to identify sub-groups based on their psychophysiological responses. These analyses showed two different groups: subjects d…
Assessing Performance on an Evaluated Speaking Task
2018
Abstract. Coping with social stress involves cognitive perceptions and the activation of several physiological mechanisms. Our main purpose was to examine how psychological factors such as cognitive appraisal, and particularly self-efficacy, may affect psychophysiological reactivity to social stress and young people’s performance on an evaluated speaking task. Thirty-five university students (18 men and 17 women) were exposed to the Trier Social Stress Test (TSST) and a control condition in a counterbalanced order. Self-efficacy, several dimensions of trait anxiety related to social evaluation, and changes in state anxiety were assessed. Additionally, heart rate and heart rate variability …
