The influence of personality on the effect of iTBS after being stressed on cortisol secretion
2019
Over the last years, individualization of repetitive Transcranial Magnetic Stimulation (rTMS) parameters has been a focus of attention in the field of non-invasive stimulation. It has been proposed that in stress-related disorders personality characteristics may influence the clinical outcome of rTMS. However, the underlying physiological mechanisms as to how personality may affect the rTMS response to stress remains to be clarified. In this sham-controlled crossover study, after being stressed by the Trier Social Stress Test, 38 healthy females received two sessions of intermittent theta burst stimulation (iTBS) applied to the left dorsolateral prefrontal cortex. To take possible personali…
Verbal performance during stress in healthy older people
2018
The impact of stress on the dehydroepiandrosterone (DHEA) response in older population is understudied. This study investigated, in healthy older people, whether the DHEA and cortisol responses to the Trier Social Stress Test (TSST) was related to performance on this task. Both speech (rated by committee and self-rated) and arithmetic (number of mistakes) performance were assessed. Sixty-five participants (55–77 years old) were exposed to the TSST. Increases in negative affect, state anxiety, and cortisol levels could be observed, but there were no significant changes in positive affect or DHEA levels. Interestingly, a larger DHEA response was related to better verbal performance after cont…
Cortisol reactivity in social anxiety disorder: A highly standardized and controlled study.
2020
Abstract In order to understand the psychopathology of the social anxiety disorder (SAD) at the neuroendocrine level, standardized experimental studies on endocrine and physiological markers are necessary, especially since empirical data are still ambiguous. Hence, differences in both, the autonomic nervous system (ANS) and the endocrine stress responses (ACTH, salivary and plasma cortisol) were investigated in a particularly homogenous sample after a standardized stressor (Trier Social Stress Test). The sample consisted of n = 35 patients with SAD, age, and gender matched to n = 35 healthy controls (HC). In terms of the heart rate, the response pattern was comparable in both groups. Conc…
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…
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.
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 …
Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress
2020
Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…
Hormonal responsiveness in the Trier Social Stress Test and the dexamethasone‐corticotropin releasing hormone test in healthy individuals
2021
A number of different laboratory procedures investigate the hormonal response in a standardized pharmacological challenge test (dexamethasone-corticotropin releasing hormone; DEX-CRH) or in a psychosocial stress induction on the hypothalamic-pituitary-adrenocortical axis by the Trier Social Stress Test (TSST). However, the magnitude of the response related to the different stressors and the interaction of the responsiveness between the two tests is still unclear. Fifty-two participants underwent both the DEX-CRH test and the TSST on two separate days. The cortisol and the plasma adrenocorticotropic hormone (ACTH) release were assessed before and after the stress tests. For a specification o…
